The doors are an exact replacement for damaged doors fitted to existing Braby storage Replacement Braby plastic door fitted to a silo silos. Commenting on the purchase, Mark Barton MD of Barton Fabrications said: ”Since Braby closed its doors in 2011 we have had requests from a number of companies to provide spares and a refurbishment service for its silos. We have been fortunate in obtaining what we believe are the only replacement Braby silo doors in Europe.” The doors are supplied undrilled ready for customer fitting to replace existing damaged doors.

Safety and automation systems from ABB will contribute to the efficient and safe operation of Statoil’s Heimdal platform. ABB’s scope comprises a new human-machine interface (HMI) for the control system, control room modifications, simulator, fire and gas detectors, integration of telecommunication in the control room and information management systems (IMS). Following the upgrades, the Heimdal platform will have ABB’s modern 800xA Extended Automation platform as the main control system, adapted to comply with Statoil’s guidelines for workstations layout and design of process graphic. According to the agreement, ABB will have the complete engineering, procurement, construction and installation (EPCI) responsibility. Today the Heimdal field has reduced its own production and the platform is now primarily a hub in the central North Sea for the processing and distribution of gas. The platform receives gas from the Huldra, Oseberg, Skirne and Vale fields and exports it via Vesterled or Statpipe pipelines for processing. At its peak the amount of processed gas in Heimdal represents 15 to 20 percent of the total Norwegian gas production. The agreement strengthens ABB’s position as a supplier of maintenance, modification and service of existing fields and confirms its ability to manage complex projects involving core areas: automation, power, telecommunication and instrumentation.

applications NOV MONO EZSTRIP™ TECHNOLOGY HELPS IMPROVE BIOGAS PRODUCTION EFFICIENCY

HIRE STATION MOVES LOW-LEVEL ACCESS OUTDOORS

The ability to reduce the average maintenance time from 1 day to just 1 hour was a key reason why a NOV Mono EZstrip™ maintain-in-place, progressing cavity transfer pump was selected by a large wastewater treatment plant in Germany. Installed at the Karanlage Plön site in Schleswig-Holstien, the pump transfers sewage sludge to an anaerobic digester for biogas creation. Operating at 294 rpm, the pump transfers the sludge at 15m3 per hour, lifting it 18 metres into the digester. “Whenever the previous pump needed maintenance it took 8-hours to strip, maintain and rebuild,” says the plant’s Abwassermeister, Andreas Laatsch. “The ability to do this to the Mono pump in one hour has cut our maintenance times dramatically and also helped reduce the associated costs.” Mono’s innovative EZstrip™ technology allows the pump to be disassembled without removing any associated equipment or pipework. By simply removing a few screws, the suction chamber is dismantled giving access to remove any rag buildup. The EZstrip™ transfer pump can be installed into new plants, or retro-fitted into existing NOV Mono Compact C installations. No electrical disconnection is required and suction and discharge pipes remain untouched “There are increasing instances where customers are realising the tremendous time and cost savings which our EZstrip™ pumps offer,” adds Mono’s Area Sales Manager in Germany, Werner Potrafke. “The EZstrip™ technology represents the biggest leap forward in progressing cavity pump design for 30 years.”

Hire Station, a member of the Vp Plc group of companies, displayed its ingenuity in providing low-level access solutions at the recent Network Rail track and plant show. Showcased on the Vp group stand was a variant of the PecoLift which has been specifically designed for outdoor use. The compact PecoLift is the first ‘non-powered’ powered access platform. It does not use batteries – so no charging requirement or mains power consumption – just step on and turn the handle. Using a unique winding mechanism, the access platform requires minimal effort from the operator to attain a safe working height of 3.5 metres, and its wheels are automatically braked on elevation. Graham Haigh, who is Business Development Director for the specialist Hire Station division that deals with low-level access for sectors such as facilities management, petrochemical and rail, explains: “Like many low-level access products, the standard PecoLift is not wind-rated and is therefore only suitable for use indoors, on a flat level surface. However, at Hire Station, we could see great potential for this product in outdoor maintenance applications. Together with the manufacturer, we came up with a wind-rated PecoLift which has all the necessary attributes for working in the open. The newly-designed PecoLift provides excellent stability, can be operated on gradients up to three degrees and has a wind rating of 12.5m/s.” Hire Station reports that it has now taken delivery of the initial batch of production machines, with further units ordered to complete the hire fleet, and has already placed equipment with clients. Initial contracts for the new PecoLift include 10 units on hire to Hertel (UK) Ltd – a leading maintenance and facility management services provider.

Pulsar’s non-contacting control for the Mersey Estuary pollution alleviation scheme Pulsar Process Measurement have supplied non-contacting ultrasonic level measurement instruments that have been incorporated into United Utilities flagship project, the Mersey Estuary Pollution Alleviation Scheme (MEPAS), providing key control and monitoring functions throughout the network of CSO/SSO chambers, vortex and interceptor sewers that form the MEPAS network. When the major Sandon Dock Wastewater Treatment Works was expanded during the 1990’s, the scheme included a substantial network of interceptor sewers and CSO, designed both to separate out solids and particulates before the main Works and to manage storm surges. Some of Pulsar’s earliest equipment was used as the project went live, including the unit that bears the serial number 0001. The Mersey is now so clean that, within a few hundred yards of the sewage treatment works itself, a scuba diving centre is flourishing, and many species of fish have re-established themselves in the river.

However, following major and damaging floods in 2010, it became clear that the existing control and monitoring regime that controlled the flow to the WwTWwas not operating as it should. The new control systems contractor, Ramptec, along with UU’s modelling team, redesigned the system operation through the 39 CSO’s within the network. Pulsar Process Measurement supported, ensuring that the ultrasonic level measurement instruments at each location were performing correctly. Under the new control arrangement, the holding capacity of the system is maximised, so storm flows to the works are better managed, discharges of untreated and semitreated sewage to the Mersey are minimised, and limits are in place and controlled accurately to avoid any risk of further flooding arising from overflow of the system. Each CSO includes three or more Pulsar units, at measurement points to maintain control and flows – within the chamber, at the outfall end, measuring river levels and within the vortex chamber feeding on to the

wastewater treatment works. Some of the applications were challenging, including measurement down narrow pipes that was previously undertaken using pressure transmitters. Pulsar remained involved throughout the project to re-establish control, providing service and commissioning support to Ramptec. As Ray Watts of Ramptec put it: ‘We have a very good relationship with Pulsar. The fact that we have their first unit, dating back to 1997, and also some of their latest equipment, proves that they supply good equipment and are able to back it up effectively’ The sternest test of the operation of the new system came in September 2012. The 25th September saw some of the worst storms on record, and the effluent height in the culvert reached 4.5m AOD (metres above ordinance datum), a volume of water that would have potentially resulted in devastating flooding if it had not been properly controlled. Both the control system and the CSO’s worked perfectly, however, releasing the excess water safely away from habitation. For more information contact Pulsar Process Measurement, Malvern, Worcs.

Ultracoat helps stop the rot in food and drink processing A proven and accredited epoxy coating system, Ultracoat from Fernco Environmental, has become the champion of the food and drink manufacturing industry, as it provides the ultimate in repair, rehabilitation and protection of grease traps, settlement tanks, manholes, and all other trade effluent chambers. Due to the chemical composition of the trade effluent, chambers traditionally built with concrete and brick will become corroded over a period of time. Effluent may then leach out into the ground, and groundwater will also infiltrate into the drainage network. As a result, the structure may become unstable, maintenance becomes more expensive and the facility may experience downtime. Furthermore, environmental issues may become legal issues. Thanks to the highly chemical resistant (pH 2-14) Ultracoat epoxy spray applied coating system, these structures can be efficiently repaired and permanently protected, extending their life by up to 50 years. Graham Howard, Technical Sales Manager at Fernco Environmental comments: “Ultracoat has been used by the food and drink industry worldwide for over 20 years and having been applied to over 50,000 infrastructure projects, the system can still claim zero failures. In addition to its excellent chemical resistance, maintenance and cleaning schedules are reduced – virtually nothing sticks to it!” Graham adds: “Ultracoat also delivers structural reinforcement, and provides excellent bonding

adhesion to damp substrates – in all pull off tests, the substrate comes off with the coating.” Containing no VOC’s (Volatile Organic Compounds) and addressing many health and safety issues, Ultracoat is also particularly suitable for application in those corroded chambers and settlement tanks that are located underground or in confined spaces. To ensure the highest standards, Ultracoat is only used by licenced applicators who have completed Fernco Environmental’s rigorous training scheme. Graham concludes: “The food industry faces ongoing pressure to cut costs and to reduce its environmental footprint from trade effluent. As many are being hit by increased effluent charges and carbon taxation, Ultracoat provides a costeffective and permanent solution for all trade effluent chambers, avoiding the disruption of replacement. In terms of whole of life costs, it is reduced to a minimum.” In addition to settlement tanks, Ultracoat is suitable for bunds, manholes, grease traps, reservoirs, tunnels and a whole host of other structures at risk from corrosion. Independently tested and approved according to a range of international standards, Ultracoat is an ideal solution for the permanent protection of chamber infrastructures.

SPIRAX SARCO DELIVERS TOTAL STEAM SOLUTION FOR PIONEERING CARBON CAPTURE PROJECT Spirax Sarco has delivered a comprehensive steam-driven heat exchange solution for a ground-breaking carbon capture project at Ferrybridge coal-fired power station in Yorkshire. The Spirax Sarco system is a key element in the success of this cutting-edge project to develop large-scale technology to mitigate the environmental damage from burning fossil fuels. Carbon Capture and Storage (CCS) technology aims to capture carbon dioxide from the flue gas of major emitters such as power stations and store it out of harm’s way, possibly by burying it in exhausted oil and gas reservoirs or saline aquifers. The Ferrybridge project demonstrates the “capture” part of the process at a much larger scale than previous pilot schemes, using an amine-based solvent to absorb up to 100 tonnes of carbon dioxide per day. Spirax Sarco’s steam system is used to re-boil and regenerate the carbon dioxide saturated solvent for reuse by stripping the carbon dioxide out under carefully controlled high-temperature conditions. The temperature and pressure in the clean-up column, or stripper, has to be controlled precisely. If the temperature is too high, the amine solvent breaks down. If it’s too low, the pressure in the column drops, which means it subsequently takes more energy to compress the carbon dioxide ready for transport and storage. According to project partner Doosan Power Systems, Spirax Sarco was the right choice to provide the steam system. For more information, please contact: Spirax Sarco, Cheltenham, Glos.

SINE PUMPS HELP TRANSFER 2 TONNES OF HAZELNUT SPREAD EVERY HOUR AT KESSKO • MasoSine SPS pumps vital to production at German sweet treat specialist • 160 containers of hazelnut spread filled every 60 minutes The Kessko factory in Bonn, Germany is using four MasoSine SPS series pumps supplied by WatsonMarlow Pumps Group to help deliver high quality ‘sweet’ products to customers in the bakery, confectionary, ice cream, biscuit and soft drink trades. At the heart of this effort, the SPS pumps offer reliable service that includes the transfer of up to 2 tonnes of hazelnut spread (containing soft solids) every 60 minutes. Inside the production hall, one of Kessko’s 180 employees enters the exact weight of 12.5kg of hazelnut spread per container into the filling system. He actuates the foot pedal and the sweet chocolate and hazelnut mixture that children so enjoy spreading on their toast, flows quickly into the containers courtesy of a MasoSine SPS pump. “We fill 160 containers in this process every hour,” says technical manager Reiner Liffmann, “which is the equivalent of 2 tonnes of hazelnut spread.”

Viscous substances

With their powerful suction, the MasoSine SPS pumps are ideal for viscous substances such as the chocolate spread being handled at Kessko. They provide a particularly gentle, virtually pulsation-free pumping operation. This is what distinguishes MasoSine pumps from other positive displacement models such as gear pumps, for example. The sinusoidal design of the rotor creates four chambers with each turn, through which the medium – in this case the sweet spread – is pumped from the inlet port to the higher-pressure discharge port. The rotor, unlike on rotary lobe pumps with multiple shafts, is powered by a motor via just one shaft. The scraper gate prevents any liquid from flowing back from the discharge side to the lower-pressure suction side of the pump. Since the chamber volume does not change, the system is perfect for pumping liquids containing soft solids or viscous media. A heated jacket for the housing is used especially for this type of application, while other pumped liquids require a cooling jacket in order to keep the temperature of the product constant. This is also available for MasoSine SPS pumps.

Thorough cleaning Even the cleaning of the SPS pumps is a straightforward process. The pump is stripped down in 10 minutes. Once the pumphead front cover has been removed, all the internal parts that come into contact with the product can be removed (without tools) and cleaned. The SPS pumps are also suitable for CIP and SIP cleaning processes. “Our four MasoSine SPS pumps are good, fast and extremely reliable,” concludes Mr Liffmann. “When it comes to acquiring our next pump, Watson-Marlow will definitely be the first port of call. We’re extremely satisfied with what they have to offer.” For more information contact Watson-Marlow Pumps Group, Falmouth, Cornwall Tel: 01326 370370 Fax: 01326 376009 E-mail: info@wmpg.co.uk Web: www.wmpg.co.uk

AXFLOW SOLVES A STICKY PROBLEM FOR TOFFEE MANUFACTURER Walkers Nonsuch of Stoke–on–Trent has been making traditional toffees for over 100 years and exports its high quality confectionery to over 35 countries. The recipes may be as old as the family business, but the same cannot be said about the processing equipment. One of the company’s recent investments has been the installation of six Waukesha Universal 1Series rotary piston pumps from AxFlow to replace rotary lobe pumps which were plagued by mechanical seal failures. The toffee production cycle starts with uncooked toffee mixture at a temperature of between 40 and 50ºC and this has to be pumped around the factory to various points where it is drawn off for the addition of ingredients that go into formulating the toffee mix. At this temperature the sugar is abrasive and viscous. Once a toffee mix has been produced, the sticky liquid is transferred to the dissolver where it is raised to 85ºC in order to dissolve the sugar. Both operations use the Universal 1 Series 60 pumps. Once the sugar has been dissolved, it is transferred by four Universal 1 Series 15 pumps to the individual cooking ovens. These pumps are governed by flow meters as it is critical that the speed of the pumps is accurately controlled to ensure a smooth production flow. Cooking is a continuous process, but the individual products are manufactured on a batch process, so there has to be a constant availability of the toffee mix into which the various additives, such as flavourings and colours, are fed. The number of hours that any of these Waukesha Universal pumps run does vary according to production requirement, but as a minimum, the pumps are run eight hours a day. Walkers Nonsuch switched to the Waukesha pumps after consulting AxFlow, the UK distributor for this pump brand, about the sealing problems that they were experiencing with the existing rotary lobe pumps. “There were two reasons why the Waukesha pumps were selected, the first being down to efficiency of the design and the second was the elimination of replacing mechanical seals,” says Production Director, Edward

The pump in the foreground is pumping raw toffee to the cookers and the pump in the background is pumping sugar and water to the initial holding tank where the raw toffee ingredients are mixed. Walker. “It was costing us around £2,000.00 every time seals needed replacing. The attraction of the Waukesha pump is that it contains a self-lubricating double ‘O’ ring seal, so the problem of costly mechanical seal failures is eliminated. In reality, the initial outlay on a new pump can be recovered in around a couple of years.” The Waukesha Universal 1 Series is a rotary piston pump that employs an operating principle known as the external circumferential piston (ECP). In this design the arc-shaped rotary pistons, or rotor wings, travel in annular-shaped cylinders machined in the pump body. The resulting long sealing path reduces slippage and produces a smooth product flow without destructive pulses or pressure peaks, and without the need for valves or complex parts. However, unlike progressing cavity and rotary lobe pumps, the Universal pump is not adversely affected by varying or viscous products that may settle in the pump. Because the rotors produce a scooping action, they do not squeeze and compact the medium being pumped. The Waukesha Universal 1 pump is ideally suited to

Site completed Niplast Tanks replace originals after 25 years Simpson Thomson Filtration (STF) Ltd, manufacturers of Niplast Storage Tanks, have replaced two bulk storage tanks, in situ, for NGF EUROPE Limited 25 years after the originals were first installed in the company’s St. Helens site. Niplast bulk storage tanks were originally installed at the NGF EUROPE’s St Helens site in 1988 and the replacement tanks will continue to store latex solutions for the company, part of the NSG Group, one of the world’s leading manufacturers of glass products. However, the contract brought new challenges. The original tanks were installed as part of the site construction, being lifted into place before the plant roof was assembled. Hence, 25 years on, STF were required to undertake the demolition of the redundant tanks and complete the construction of the new tanks in situ, within the plant. STF also undertook the licensed disposal and 100% recycling of the original polypropylene tanks. The two 30,000 litre Niplast tanks have been designed and manufactured to British and European Standard BS EN 12573 Welded Static Non-pressurised Thermoplastic Tanks which was adopted by the BSI in 2000. The key tank components were manufactured at STF’s Stockport factory, primarily the tank roofs, base sections and wall cylinders. STF Managing Director, Adrian Greenwood said, “The 25 year’s service provided by the original Niplast tanks demonstrates the excellent service life achieved by thermoplastic tanks constructed to BS EN 12573. The provision of the new tanks shows the flexibility of this design standard and the manufacturing and testing techniques.” For further information about Niplast contact Storage Tanks Tel: 0161 477 6777 E-mail: info@niplast.com Web: www.niplast.com

confectionery manufacturing because it can handle both thick and thin fluids without causing any damage to the pumped product. It combines a very gentle, pulse-free pumping action with the high suction capacity necessary for allowing the thick mix to be drawn into the pump without any separation of the ingredients. The pump uses double ‘0’ ring self-lubricating sealing system for all applications, which allows high vacuum to be developed on the inlet side. Manufactured from stainless steel and suitable for CIP cleaning, the pump’s close clearances allow the pumping of water against back pressures, whilst its simple design enables operators to completely strip it down for inspection in situ without the need to remove connecting pipework. Where high viscosity fluids and solids are involved, the large fluid cavities of the rotors, together with the large easy-entry anti-cavitation ports enable efficient pumping. Maximum service life can be achieved even under severe operating conditions where fluids are non-lubricating or abrasive because there is no contact between the bearings and the pumped fluid, nor is there sliding or rolling contact and rotor-to-rotor contact. According to Edward Walker, it is now about two years since the first of the Waukesha pumps was installed and following on from the success of the pump the other five units have been installed as required. Should there be a need to shut one of the Waukesha pumps down, it can be quickly removed and flushed out in a very short period of time in situ. “When you are making up to as much as 40 tons of toffees a week and having to satisfy orders from customers from all over the world, minimising downtime is a key issue,” comments Edward Walker. “The removal of the old pumps and their replacement with Waukesha Universal 1 Series pumps has removed the uncertainty and costs of mechanical seal failure, and at the same time is contributing to efficiency.” For more information contact AxFlow Limited, Ealing, London Tel: 0208 579 2111 E-mail: info@axflow.co.uk Web: www.axflow.co.uk

Transforming your sustainability with robotic automation Sustainability has become something of a buzzword in modern manufacturing processes. Often requiring investment to bring about the changes needed, it presents something of a double-edged sword for companies seeking to enhance their reputation through sustainable practices

whilst enhancing their competitiveness through reduced costs. With the potential to completely transform production processes, robotic automation is a good example of an investment that can yield improvements in both sustainability and cost performance that can greatly improve competitiveness.

Few would argue that these are tough times for manufacturing and processing companies. As well as having to contend with the toughest set of economic conditions in living memory, there are the added pressures of spiralling energy prices, rising input prices and fragile consumer demand. Not only that, but today’s companies are subject to increasingly stringent legislation governing everything from product quality through to minimising the environmental impact of their operations.

energy is now by far the most significant overhead for any company. It is therefore imperative to find ways to use it more efficiently.

For many companies, the concept of sustainability is the latest addition to this list. The idea has been gathering momentum in recent years, as consumers have become more aware of the environmental issues associated with manufacturing processes and produced goods. Basically defined, it promotes the idea of shaping our activities so that we can enjoy the materials and resources, including water and energy, that we need both now and in the future. Although it often requires associated changes and investment, acting sustainably can invariably have a positive impact on consumer demand that can lead to improved sales, making it a valuable differentiator and competitive tool. As a means of reshaping production processes to become more efficient, reliable and less prone to problems caused by wastage and poor quality, modern robotic automation can deliver major benefits for companies that often see investment being recouped within just 18 months. The following are some examples of how introducing robotic automation can help companies to improve their performance in some key areas associated with sustainable performance.

Energy Energy represents the most vital resource for every manufacturing process. Yet with supply being steadily outstripped by demand, it is no longer a resource that can be taken for granted. The United Nations Industrial Development Organisation’s (UNIDO) recent ‘Industrial Development Report’ points to the need for investment in energy efficient technologies at all levels in order for sustainable growth to be achieved. To paraphrase UNIDO Director General Kandeh Yumkella, industrial energy efficiency is a key issue that needs to be tackled in order to ensure continued growth, employment and mitigation of climate change. The knock-on effect of shrinking supplies is already being felt in rising energy prices in the UK. With energy prices having risen by well over 50% in the last 10 years,

With no requirement for minimum lighting or heating levels, robots offer a great opportunity to cut energy bills. Current estimates point to a potential saving of 8% for every 1°C reduction in heating levels, while savings of up to 20% can be achieved by turning off unnecessary lighting. Aside from their ability to work in unlit and unheated environments, robots also present massive opportunities to help save energy through longer-term productivity improvements, particularly in the area of reduced wastage, as I shall show below.

Wastage Closely linked to the inefficient use of energy is wastage. Every product that has to be reprocessed requires additional energy, materials and cost to make it. Not only that, but there is the additional cost and environmental impact associated with disposing of the ruined product and / or any associated waste. As a means of producing and handling hundreds of products quickly, repetitively and accurately, robotic automation has been proven to virtually eliminate product wastage. As such, reduced wastage can make a major contribution to more sustainable production practices, by enabling products to be produced correctly first time, optimising the use of materials, and reducing the amount of energy, with less capital spent.

Flexibility One of the biggest areas that companies need to address to improve their sustainability performance is product and process innovation. In essence, this focuses on the need for companies to find new ways to remodel their production processes and find ways to reduce the environmental impact of their product offerings, both during production and after, at the disposal stage. Robotic automation can help in both these areas. For one, robots offer a very high level of flexibility as they can be programmed to handle a large number of product variations and sizes. With the availability of simulation and offline programming software suites, programming the production line in advance can increase overall productivity and enable shorter change-overs between products. The ability to produce a greater range of products without causing considerable downtime can not only increase profitability

Mike Wilson, General Industry Sales and Marketing Manager for ABB’s UK robotics business, explains how.

but enable tasks such as training, programming and optimising plant processes to take place without disturbing production. A real life example of how flexible robots can be in production is the Youngman Group. The manufacturer of micro powered access, Ecolite lighting towers, ladders, steps and mobile access towers introduced two of ABB’s IRB 1600 robots to dramatically improve flexible production and reduce stockholding. The answer was to install two fully, automated welding cells. The welding cells were programmed to operate around the clock, six days and a week. The labour-saving benefits, improved flexibility and safety aspects of the new system are impressive in their own right, but the proven capabilities of the system ensures products can be quickly and perfectly handled with a high level of precision and consistency.

Summary For many manufacturing processes, robot-based automation offers improved flexibility, productivity and reliability, helping manufacturers to meet ever shorter product life-cycles, multiple product variants and rising energy and material costs. As demonstrated, the tangible benefits of robotic solutions have become ever more apparent and it is widely accepted that robots will be adopted at a much higher rate across the manufacturing industries where long term sustainability and reputation are paramount. The challenge for manufacturers now is to reassess their strategy to identify the opportunities and exploit the sustainable and environmental advantages of integrating robot-based automation into modern manufacturing processes. With the potential to completely transform production processes and introduce sustainable production, there is no longer a reason to avoid an investment that is widely proven to also greatly improve your competitiveness.

The role of maintenance and asset management in optimising plant performance By Ian Ritchie, Managing Director, Brammer UK

Irrespective of the economic situation, the key drivers of manufacturing competitiveness and profitability remain the need to optimise production output and efficiency whilst reducing operational costs. If an efficient and reliable plant is the key driver of success, then the way in which a company approaches its maintenance and asset management strategy is critical. A best-in-class approach to optimising manufacturing plant performance will align the strategies, goals and metrics of the production and maintenance teams, fostering collaboration between these teams to aid effective prioritisation and decision making.

a general reduction in capital investment in new plant and equipment. Many companies are instead focused on driving existing assets over an extended lifespan, frequently while working within reduced operating budgets.

should always focus on the total cost of ownership, rather than the initial purchase cost, with factors such as component lifespan, spares criticality, reliability, reduced maintenance and service intervals all contributing to the purchasing decision.

Common objectives should be standardised around typical metrics used by best-in-class manufacturing companies such as Overall Equipment Effectiveness (OEE) â&#x20AC;&#x201C; measured as a percentage by multiplying plant availability, performance and quality â&#x20AC;&#x201C; and asset downtime, measured as the amount of time the asset is offline against total asset availability.

An effective maintenance and asset management strategy is absolutely critical to meeting these challenges while delivering on operational performance, service levels and overall company profitability targets.

Ultimately, the strategy should concentrate on identifying the most common and machine-specific spares, and ensure that critical spares are always available. Wherever possible, stock value and the number of stockkeeping units held should be minimised, with the number of suppliers minimised to reduce inventory and working capital tied up in maintenance spares as well as the transactional costs associated with maintaining duplicate suppliers of the same thing.

In order to maximise OEE and minimise asset downtime, plant must be both well operated and well maintained, with vital spares available when needed and unscheduled downtime minimised. This is brought firmly into focus by the fact that unplanned production downtime can throw manufacturing schedule adherence into disarray. It can often cost many thousands of pounds per hour, and can be commercially damaging for companies in asset intensive industries. Lost production time can mean a failure to meet a tight order deadline and even the consequential loss of one or more highly valuable customers. It can also be further complicated by the issues brought on by ageing plant and equipment. This is becoming an increasingly important factor since the recent recession as economic and financial pressures have influenced

Developments in maintenance strategy A best-in-class approach to maintenance and asset management strategy is to move from a reactive approach â&#x20AC;&#x201C; where plant is run to failure, often supported with high levels of engineering stock and characterised by unreliable performance and frequent breakdowns - to proactive and condition-based maintenance management. A reliability-centred approach goes a long way in helping companies to avoid asset failure and to fix potential problems relating to production assets before they actually have an impact on unscheduled plant downtime. Making effective asset maintenance decisions requires organisations to equip their employees with the right data at the right time and in the right format. This may include the adoption of condition monitoring techniques such as vibration analysis, thermographics, oil sampling and acoustic analysis to assist in the monitoring of plant performance. While this approach requires a significant evolution in maintenance strategy and execution for many manufacturers, its impact is being widely proven in safeguarding production schedules, adding new efficiencies to operations, reducing maintenance costs, improving spares management and even lowering energy consumption. For example, scheduled maintenance to a motor or compressor whose energy usage has been monitored and identified as exceeding the level expected, can help identify the contributing factors and allow a programme of corrective action to be developed and implemented reducing both energy usage and future asset downtime. This is just one instance of how energy consumption data can be highly valuable in informing operational decisionmaking and contributing to OEE. Whatever approach to maintenance is adopted, its goals and metrics should always be closely aligned with those of production and procurement teams to ensure a consistent and collaborative approach to the spares purchasing and management process.

Best practice in maintenance management Maintenance spares management also plays a significant part in achieving the goal of improving overall efficiency in manufacturing operations, helping to maintain continuity of production and avoiding costly downtime. A successful maintenance spares sourcing strategy

Process Industry Informer September 2013

The maintenance management strategy should also focus on an engineering spares standardisation programme, which has the potential to significantly reduce inventory and the cash tied up in stock, while ensuring a consistent standard of components is used across the asset base.

The benefits of outsourcing The purchasing of spares for the daily maintenance and repair of production and manufacturing equipment is often a complex, time and resource consuming activity for most organisations. When well managed, however, this is an operational area that can provide considerable added value with major cost savings generated through demand reduction, reduced inventory, production and maintenance improvements. Where the procurement and spares management process is large-scale or complicated, there is much to be said for outsourcing part or all of the function to a specialist MRO partner. The right partner should be able to offer a strong combination of procurement and supply chain management expertise, combined with valueadding services such as condition monitoring, energy audits, drive system design and lubrication programmes to support the maintenance and asset management strategy. This enhanced level of support can free up valuable in-house procurement, production and maintenance capacity to focus on improvement projects to increase production output and efficiency. Outsourcing of some, or all, aspects of MRO spares management is consistently proven to reduce total acquisition costs and working capital, while the right partner can also add value to the engineering team to support the goal of optimising plant uptime and production output. In the current economic climate, where capital investment is being restrained, and therefore plant asset life is being extended, an effective maintenance strategy is the key to improved manufacturing plant reliability and higher operational and financial performance.

Sweating Your Assets –

More!

Throughout industry, pressure to squeeze maximum return from each and every asset is intense. This principle drives the focus on process simplification, and on maximizing efficiency in production. Such strategies have become vital for day-to-day operations in most sectors, and return considerable value. However, business leaders targeting the very highest levels of excellence are now extending this rigour to other aspects of their companies and, for example, are recognizing the additional value that proactive management of idle and surplus analytical, plant and packaging equipment can deliver. In this article Ben Potenza, VP Marketing, EquipNet, examines emerging best practice in this area, pointing out what to look for in the solutions offered, and illustrating what proactive asset management is delivering to the pharmaceutical, biotech, chemical, food, beverage, and personal care companies that are their clients.

Significant asset base idle and underutilized Today’s companies hold enormous value in the form of equipment and plant. Keeping an accurate asset register provides a solid basis on which to make management decisions, but research suggests that on average, 5% of a manufacturing company’s global asset base is idle, with most not having good visibility of these underutilized assets. Of course, businesses have always traded surplus assets, and equipment dealers and auctioneers have been there to help. But increasingly, more sophisticated tools – tools that can develop a comprehensive inventory of assets and support their utilization across multiple sites as needs change – are being systematically implemented. In parallel, there has been significant growth in the market for the sale and purchase of surplus equipment.

Challenges and opportunities Progressive businesses strive constantly for an efficiency edge, but in recent years, the tough economic climate has driven consolidation, relocation, mergers & acquisitions, outsourcing and plant closures in almost every sector and company. The result? More executive teams see that a focus on managing assets can deliver directly to the bottom line. Once a decision has been taken to proactively manage the asset base, a company must consider a series of choices. For many, the variables are clear – redeployment vs. disposal, or realizable value vs. available time, for example. But every situation is different – reusing equipment within an organization always delivers the highest value and, with time available to do this, some companies will have this as the sole focus. Disposal is a secondary consideration that only comes into play if redeployment is not needed. For other organizations, perhaps where a site or line is being closed, time may be short and releasing as much value as possible within the available window is the overriding factor. Whatever the goal, the process is logical, and straightforward, but like much in business it needs to be carefully planned, and rigorously executed in order to maximize returns. For most executive teams asset management is a ‘non core’ activity, so contracting with an external specialist that can bring industry expertise and experience to bear, whatever the size and shape of the project, is an attractive option.

The right tools for the job As noted above, auctioneers and equipment dealers offer their services in many industrial sectors. However, there is a view evolving of what best practice in asset management looks like, and specialist companies (such as EquipNet) have become established leaders. A holistic approach that balances the needs of a company can be developed. EquipNet describes this with its ‘Value Control Model’. Figure 1 shows how redeployment, negotiated sales with managed pricing through an on-line marketplace, competitive auction events and clearance programs fit together to deliver a consolidated service, whatever the individual needs of a company. Fig 1. Assets are liquidated using a range of strategies

We can pull this apart to consider the key components. Importantly,

what ties the redeployment part of the model together is the availability of an asset tracking platform that can be installed across multiple sites. Users should be able to post, track, identify and internally redeploy equipment that is not being used in its present location, ahead of moving to external sale. An established example is EquipNet’s ARMS™ (Asset Redeployment Management System) platform. This simple, yet robust program sits behind the company firewall, and features workflow management, multiple access levels for plant managers and executives across the business, in-depth search functionality, and comprehensive listing specifications, providing information that lets the company know what they have and where it’s located. The rise of the internet has seen the development of online marketplace products. Innovative features to look for here include: • ‘Top-down’ offers rather than the more usual ‘bottom-up’ bidding model • Expert evaluation of goods offered for sale, and accurate setting of sale prices • Concentrated promotion of the marketplace platform and, within it, advertising of specific equipment • Payment by results Auctions are another dependable channel but the competitive nature of auction events can produce wildly differing results, designing and managing a successful auction event depends on many factors. A specialist partner should advise on the right approach in each case; your options might include online auctions, live/webcast auction events, sealed bid and private treaty sales. Innovation should be at work here too, look out for active marketing by the auction provider, expert knowledge of the equipment being offered for sale, and a flexible approach to managing bids close to, but under any reserve set. Figure 2 shows how bids that most auctions would ignore are picked up and processed by EquipNet. There are those assets that hold very little value and are best dealt with through clearance, by donations, scrap and environmental Fig 2. Flexible management of bids close recycling. Working with to any reserve can deliver higher ROI your chosen expert, you should expect to be advised of the scrap value of your idle equipment, presented with a comparison of that amount against the market value to sell it, together with a recommended strategy that will generate the highest rate of return for your company.

In summary Pursuing a proactive asset management strategy is not without its challenges. It requires formalised processes, specialist knowledge of the industry and its equipment, dedicated resources, and a concerted effort to change management. Many companies lack the time or resources that are necessary to establish a successful program themselves. For this reason, the majority of companies that are succeeding in this area are relying on a partnership with a specialist service provider. They are enjoying the clear benefits of cash release, reduced costs, and increased efficiency.

A guide to pressure t materia

The risk of corrosion presents a serious threat to the long term operation and accuracy of pressure transmitters, particularly in critical measurement applications. One way of minimising this risk is to ensure that your pressure transmitter is made from the correct materials to enable it to withstand the rigours of your application. Trevor Dunger, Product Specialist for ABB’s UK Measurement Products business, explains the various choices on offer and how to choose between them. When selecting a material for a pressure transmitter it is necessary to consider both their resistance to corrosion and their suitability for the specific application in question. For example, the filling fluids used in a pressure transmitter mean that they cannot be used in direct contact applications such as in the food and beverage industry, as any leakage could corrupt the process. Corrosion is a major challenge in many pressure measurement applications. Corrosion is the gradual destruction of a metal either by chemical or electrochemical means. The speed and aggression of corrosion can be determined by a variety of factors, ranging from different types and combinations of chemicals through to temperature, particularly in high temperature applications. For example, temperatures above 40°C (104°F) in seawater can increase the risk of corrosion of stainless steel components through pitting. Where materials selection is concerned, it is important to remember that there is no ‘catch-all’ solution that will be suitable for all types of application and process conditions. With the onus sitting squarely on the user to make the right selection, it is therefore essential that you make a careful and detailed analysis of your process in order to correctly specify the materials for your device. If in doubt, it is always best to consult a pressure measurement expert, who can suggest possible solutions. The following section contains advice on some of the most common materials used for the wetted parts of pressure transmitters, these being the components that come into direct contact with the process.

316L Stainless steel 316L SST offers good resistance against corrosion, including low concentrations of nitric acid and most salt solutions and as an example it is used as the standard material for the wetted materials of our 2600T pressure transmitters. When it comes to alkaline solutions, organic acids and other organic compounds, the resistance of 316L SST against corrosion may depend on temperature. Certain halide salts, including fluorine, chlorine, bromine and iodine, can also cause severe pitting and stresscorrosion cracking. For oil and gas applications, where hydrogen sulphide is often present, 316L SST may be available with specific NACE MR0175 certification. This standard defines the types of corrosion resistant materials that can be used in various oil and gas industry environments. As such, it covers most types of stainless steels, including 316L SST. By setting criteria both for the hardness of the material and the process by which it is manufactured, the standard helps to reduce the risk of sulphide stress corrosion cracking. The standard also covers non-wetted parts such as bolts, as they also have a bearing on the instrument’s overall containment effectiveness even if they are exposed to corrosive environments far below the limits of the standard. The NACE certificate is also available for other materials including Monel and Hastelloy C.

Monel Monel offers good resistance against the corrosive effects of most of the non-oxidising acids, such as hydrofluoric, sulphuric and phosphoric acids, at ambient temperatures. Monel is also considered the prime choice for applications where components are in contact with sea water. Despite its general high resistance to corrosion, Monel is not suitable for contact with acid and alkaline oxidising sales, which can cause severe corrosion damage. Applications with a high hydrogen concentration may also affect Monel’s effectiveness as a material of construction. Especially where Monel is used as a diaphragm material in hydrogen gas processes, hydrogen atoms may permeate the diaphragm, leading to hydrogen bubbles forming within the fill fluid.

Hastelloy C Hastelloy C is comprised of chromium and molybdenum added to nickel to improve the alloy’s resistance to oxidising conditions. As such, Hastelloy C is well suited for protecting against the rigours of alkalis, organic acids and other organic compounds. Hastelloy C also offers good protection against oxidants such as phosphoric acid as well as acid salts including nickel and copper chlorides. At moderate temperatures, Hastelloy C is able to withstand hydrochloric and sulphuric acids in most concentrations. Like Monel, Hastelloy C also affords good protection against atmospheric conditions and fresh water.

Gold plated Hastelloy C, Monel or SST Hastelloy C, Monel and SST can all be permeated by hydrogen, meaning that they should be avoided as a diaphragm material for use in applications where hydrogen is present. Hydrogen atoms can diffuse through the very thin transmitter diaphragms into the fill fluid, whereupon they can combine with the fluid to form molecular hydrogen. This is particularly a problem at elevated pressures and temperatures, which increase the permeation rate. As molecular hydrogen is too large to permeate back through the diaphragm, it becomes trapped and forms bubbles in the fill fluid. As these bubbles form and accumulate, they can severely affect transmitter performance. One way to prevent this problem is to plate the diaphragm with gold, which prevents hydrogen permeation at high process temperatures and pressures. Another form of protection available from ABB is a corrosion resistant hydrogen preparation gel, which can be applied to a pressure transmitter’s diaphragm to reduce hydrogen permeation.

Tantalum Tantalum is an ideal alternative to 316L SST in corrosive applications featuring a range of chemicals including hydrochloric, hydrobromic, boiling hydrochloric, nitric, phosphoric and sulphuric acids. It has a high melting point and good strength even at elevated temperatures.

With the exception of aluminium fluoride, potassium carbonate and sodium sulphide, to which Monel is more suited, Tantalum offers a good resistance to most acids, chemical solutions and organic compounds, as well as liquid metals. Despite this, Tantalum can suffer severe embrittlement if used with high temperature oxygen or nitrogen, or with hydrogen at any temperature. It is also prone to attack by strong alkaline solutions and by fused alkalis such as sodium hydroxide.

PFA (Teflon from DuPont) PFA (Teflon) coating offers outstanding protection against corrosion and anti-stick properties, with even a 0.2 to 0.3mm coating capable of providing a cost effective alternative to more expensive methods, such as the use of specialised materials. A limitation of a PFA coating is its recommended temperature limit of 200°C (392°F) and a minimum increase of the temperature effect on accuracy. Also, if the diaphragm is subject to mechanical abrasion (rapid flows with solids) it can become punctured, allowing corrosion to penetrate the area below the coating.

Other points to consider Aside from the materials of construction, there are also other factors that can affect the operation of a pressure transmitter. One important aspect is the selection of the appropriate fill fluid. Making the correct choice is especially important as the type of fill fluid can limit the working temperature that the transmitter can stand.

Process Industry Informer September 2013

transmitter als selection

For this reason, it is advisable to choose a fill fluid that can be used over the widest possible range of operating temperatures. The most widely used is Silicone Oil DC200, which offers high stability over temperatures ranging from -40°C to 200°C (-40°F to 392°F). Alternatively, other fluids may be selected whenever their temperature range is compatible with the application, in order to take advantage of a lower viscosity or thermal expansion factor. This is especially useful where faster response times are required in remote seal applications with long capillaries. In some applications, such as food and pharmaceutical production processes, it may also be undesirable for certain fill fluids to be used, in order to prevent potential product contamination caused by a ruptured diaphragm. Where this is the case, a food sanitary fill fluid should be selected. An alternative fill fluid should also be used for transmitters used for oxygen rich applications , where leakage of a silicone oil fill fluid could cause a fire. For this reason, an inert fill fluid should be selected. Another important aspect concerns the selection of the appropriate material for the transmitter gasket. The most widely used material is PTFE (Teflon), due to its general corrosion suitability with several materials. However, a potential drawback of PTFE arises in processes subject to periodic variations in temperature. Particularly in processes where the temperature varies by several degrees, the limited elasticity of PTFE can compromise its tightness. In these instances, it would be wise to consider the elastomer Viton. Special requirements may also arise in food or pharmaceutical applications, which frequently call for an approved material listed by the US Food and Drug Administration (FDA) or other national equivalent organisations.

Summary As one of the most ubiquitous process parameters, pressure measurement needs to be conducted across a wide range of operating environments and process conditions. Given the wide variety of pressure ranges and operating conditions, having a good understanding of how to specify a device can be a useful first step in ensuring it fully meets the requirements for a particular application.

More efficiency from motors An accurate calculation of motor efficiency opens the door to long-term savings and backs up any initiative to improve plant profitability with a reliable set of data. And what’s more, explains Phil Burge, Country Communication Manager, SKF, even manufacturers with a relatively small number of motors in operation can achieve measurable payback. As long as environmental and economic needs stay at the top of the agenda for modern businesses, a more reliable, safe and beneficial method of enabling efficiency will always be vital to reduce energy demands and the impact on global warming. As one of the biggest energy consumers in industry, motors must be scrutinised to ensure that they are running as efficiently and smoothly as possible. By determining the efficiency of a motor, users can then correct the issues that directly affect energy usage, such as cavitating pumps and improperly tuned drives, and start increasing the efficiency and service life of the motor while also reducing maintenance costs, downtime and production losses. Industrial motors have something had a bad reputation, which is hardly surprising when you consider the statistics. Indeed, they are responsible for consuming about 65% of all generated electrical energy, account for up to 75% of the total electricity costs in industrial plants and use 50% of the total electricity consumed by commercial buildings. In addition, it has been said that the annual cost of operating an electric motor can reach a staggering 25 times its original purchase cost. Nevertheless, there is great potential to further reduce energy use in most sectors and economies. Many analyses have demonstrated that the total overall efficiency with which we use energy to provide the final demand of energy services in society is as low as 10-15%. This means that we as society “waste” as much as 85% of all the energy we consume. An even more striking case in point is lighting; an incandescent light is less than 5% efficient- and if you include in your calculations all the system inefficiencies inherent in generating, transporting and transforming electricity, the overall efficiency becomes – believe it or not -less than 1%.

Take account of statistics… The statistics can be daunting, but they also underline the importance that we work together as a coherent force with a consistent approach. A large amount of waste can be converted into a correspondingly large energy saving if attitudes to energy efficiency are transformed. We are in this together; and together is the only way we are going to solve the problem. A systems approach will help claw back some of the staggering amount of electricity consumed across industry by electric motors, and this begins with the calculation

of motor performance. The effort will be worthwhile; a systems approach will enable operators to capitalise on significant savings and rest assured that they are truly maximising their energy efficiency, not just solving a part of the problem. By correctly matching load and energy use, ensuring proper sizing of all components, improving the efficiency of the end-use devices such as pumps and fans, and reducing electrical and mechanical transmission losses, inefficiency can be significantly curtailed. In fact, by addressing each issue it has been estimated that the electricity use of industrial motor systems can be reduced by as much as 30%. When making that initial calculation of motor efficiency, the Instantaneous Current Method is considered the most accurate and less intrusive of the options available, and looks at output power rather than trying to estimate losses. As this element is less sensitive to the efficiency of the predicted motor, the margin for error for estimating lower end efficiencies is smaller and ensures maximum precision. In essence, the Instantaneous Current Method requires a measurement of the motor input power and a calculated estimate of the motor output power, with current and potential transformers being used to gather incoming rotating voltage and currents for all three phases. Calculations are then made based on these values for speed and torque, while air gap torque is worked out using the Park’s Vector, or 2-Axis Theory. Friction, stray load and windage losses are estimated and then subtracted from the air gap torque calculation to get an estimate of the output torque, while speed is estimated through the gathered currents and voltages. For example the EXP4000 Dynamic Motor Monitor from SKF uses the proven Instantaneous Current Method to give users a comprehensive look at overall motor performance and integrity. This instrument calculates the operating efficiency then extracts a comparable efficiency from a motor database that contains over 22,000 different NEMA design motors from numerous

motor manufacturers. The percentage difference in the losses between the tested motor and a comparable motor with the target efficiency is then evaluated with respect to the thresholds. Ultimately, it identifies motors that are performing under par and calculates the payback period if replaced by a new motor.

Making the case... In response to a sharp rise in local energy costs, Indonesian textile plant PT. Leuwijaya Utama implemented an urgent cost-saving programme, and discovered that 30% of the factory’s energy consumption was consumed by the twisting machines, which are critical in ensuring fabric quality. So, as well as taking measures to correct electric motor energy losses and optimising frequency converters for the overall electricity supply, the energy consumption of the twisting machinery was examined in closer detail. Inside the Leuwitex twisting machines, lines of high precision spindles are driven by two powerful motors. As these machines operate 24 hours per day, frictional losses (and ultimately energy losses) occur in the rotational motion dependant on the quality of the bearings fitted at the ends of each spindle. With 176 twisting machines incorporating 256 spindles, this clearly presented an opportunity for a major energy saving. By installing our Energy Efficient (E2) deep groove ball bearings, frictional losses were reduced by 30% over a standard SKF bearing and achieved 10% total energy savings. So, the means exists to conduct an evaluation of motor efficiency and the benefits can be considerable. All that needs to change is the attitude that accepts high energy consumption as an unavoidable fact and assumes that nothing can be done.

Energy Savings Opportunity Scheme (ESOS) The Department of Energy and Climate Change published in July its ESOS consultation document which seeks views on the Government’s approach to implementing Article 8 of the EU Energy Efficiency Directive, which was agreed by Member States on 25 October 2012 and came into force on 14 November 2012.

Background 1. Article 8 of the EU Energy Efficiency Directive (‘the Directive’) requires all Member States to introduce a programme of regular energy audits for ‘large enterprises’.1 Audits must be undertaken by 5 December 2015, and then at least every four years from the date of the previous audit. Government believes that this programme offers a significant opportunity for the UK. It will help drive the take-up of cost-effective energy efficiency measures by participants, benefiting their competitiveness and contributing to the wider growth agenda. 2. The ‘Energy Savings Opportunity Scheme’ (ESOS) is the Government’s proposed approach to implementing this requirement. Under the scheme, approved assessors will carry out Article 8 compliant ESOS assessments to identify energy saving recommendations. While the Directive prescribes many of the key features that ESOS must include, there is some limited scope for flexibility and interpretation. This consultation document seeks views on a range of detailed issues around the implementation of ESOS. 3. Following this consultation, the Government will analyse consultation responses and then develop secondary legislation, setting out the legal framework for the operation of ESOS. The Government also proposes to develop good practice guidance to support organisations and ESOS assessors in conducting ESOS assessments. 4. The Government’s guiding principles for implementing ESOS are to: • ensure that ESOS provides high quality and well-targeted advice to large enterprises on cost-effective energy efficiency opportunities, driving significant net cost savings; • ensure a proportionate approach to implementation is taken, minimising the administrative burdens placed on UK businesses; 2

• ensure ESOS fits with and is complementary to the landscape of existing energy efficiency and climate change policy instruments; and • ensure our implementation of Article 8 avoids ‘gold plating’ that disadvantages UK businesses relative to their European competitors. 5. The Government’s Energy Efficiency Strategy set out the substantial, untapped and cost effective energy efficiency potential which exists in the UK economy.2 Through the right action we can unlock more of this cost-effective potential, and help to reduce energy bills at a time of increasing gas and electricity prices, balance the UK’s future energy demand and supply needs, and cut our carbon emissions. 6. The current economic climate makes it more important than ever for individuals, businesses and the country to realise the benefits available from reducing energy demand. Doing so will help support productivity of UK firms and improve the UK’s international competitiveness.

Who will this scheme apply to? 7. The proposed scheme would apply to all large enterprises in the UK (primarily businesses but also charities and any other UK organisations outside the public sector, if large enough). 8. Small and medium enterprises (SMEs) will not be required to participate, unless they are part of a large corporate group enterprise.3 SMEs will be able to carry out ESOS assessments on a voluntary basis and the Government encourages SMEs to consider such voluntary action. 9. To make it easier to determine whether a corporate group would be included in ESOS, the Government proposes that the scheme would only target those corporate groups where there are one or more large (i.e. non-SME) UK companies within the corporate group. If every UK company in the group enterprise was an SME, the group would not be covered by the scheme. 10. The scheme does not extend to public bodies. NB. The consultation closes on 30 October 2013 and BPMA convened a meeting with its members on 4 September to consider the BPMA response.

WEG launches new energy efficient standard motor range with 40% less losses WEG, a global leader in electric motors, has launched a new range of motors that represents a major breakthrough in providing high levels of energy efficiency – the W22 Super Premium. The innovative electric motor is the only complete standard range available on the market worldwide that exceeds the yet-to-be-implemented IE4 regulations, enabling manufacturers to increase energy efficiencies significantly throughout their plants and processes, and reduce their total cost of ownership. The W22 Super Premium gives outstanding performance across the full power range from 3 kW to 355 kW and presents up to 40% less losses compared to previous designs. The threephase induction motor is based on WEG’s popular W22 motor mechanical design and meets the requirements of the most demanding industrial users, giving reduced energy consumption, increased productivity, extended lifetime and lower maintenance. It is ideal for industrial applications including fans, blowers, pumps and compressors. With features like an innovative aerodynamic frame, redesigned cooling system and unique insulation system, the W22 Super Premium range of motors is quieter, more reliable, easier to maintain and more cost-effective. The motor has been designed to have low operating temperatures, which increases the

insulation time and results in a long service life. The frame and cooling system of the motor has been optimised to deliver exceptional airflow to its components, improving operating efficiency even in tough environmental conditions. It delivers increased lubrication intervals and therefore needs minimal maintenance and servicing. High performance rubber drains allow for easy motor drainage during servicing, and provide high protection at harsh conditions. Special bearing seals also extend the lifetime of the motor in aggressive environments by protecting it against the ingress of water and dust. It has a flexible terminal box design for the 225 – 355 frame sizes, whereby the terminal can be positioned on the top or side to best suit the application. The W22 Super Premium range is modular, reducing inventory costs for manufacturers by enabling a common motor frame to be used with different types and sizes of terminal boxes. The motor is robust with solid integrated feet, which provides a tough construction and enables easier installation and alignment. Motors in frame sizes 160 and above are fitted with flat surfaces which allow vibration detectors to be fitted easily, an important advantage for condition monitoring and preventative maintenance schedules. Suitable for low voltage supplies, the W22 Super Premium motor range covers 2, 4 and 6-

pole motors in frame sizes up to 355. They are designed according to DIN EN 50347 Standard, which means that customers can replace an IE1, IE2 or IE3 motor with total reliability. “As motors typically run for thousands of hours every year, any gain in efficiency by replacing motors with higher efficiency versions, equates into considerable savings which would pay for the investment in a few years, and in some cases even months,” says Marek Lukaszczyk, European marketing manager at WEG. “The new W22 Super Premium motors allow a low total cost of ownership thanks to its reliability, easy maintenance and energy savings, and enable users to reduce their carbon footprint.” The introduction of the W22 Super Premium range means that WEG now has the widest range of energy saving motors for industry. For further information about the W22 Super Premium range of motors visit www.weg-ie4.com

Pump-attuned valves improve energy efficiency

By Uwe Herberger-Rosin – KSB Aktiengesellschaft

In actual practice, roughly one out of three check valves installed in pump systems is causing major losses due to improper selection. Particularly in connection with system conversions and overhauls, more attention should be paid to the proper selection and positioning of such valves. Check (or non-return) valves are needed when a pump is stopped and the liquid column acting on the discharge nozzle or the pressure generated by other pumps operating in parallel could cause the impeller to reverse direction. Sensitive components like unidirectional mechanical seals could sustain damage as a result. If an appropriate valve is installed, any reversal of flow will close it, thus providing reliable protection against reverse flow. Often, however, lift check valves and dual plate check valves are installed without first having examined the prevailing flow conditions and resultant energy losses.

BOA RVK wafer-type lift check valve

Frequently, the pump is the major point of focus at the time of installation, while the check valve is selected en passant, so to speak. Depending on the equipment constellation, this can cause serious wear and tear on the valve or even keep the system from achieving good performance. The advent of speed control systems, though, has changed the situation for check valves. While pumps used to be either “on at full load” or “off”, many units are now operating at reduced speed in the partload range. When lift check valves are used, low flow velocities can cause constant “opening and closing”, because, unlike dual plate check valves, they are unable to reliably maintain a partly open position. Consequently, they might use up their entire service life in terms of opening/closing cycles within a few weeks. High volume flows can also cause problems due to high flow velocities in the narrow gaps at the disc/seat interface. This can lead to such pronounced wear and vibrations as to cause the eventual failure of the valve. Indeed, resonant vibrations might even cause damage to the pump itself. Frequently, the connecting piece between the pump and the check valve is too short. As a rule of thumb, the valve should be situated at least the equivalent of five nominal diameters away from the pump – a length referred to as the flow stabilisation distance. In a study conducted by KSB, more than 30 percent of all check valves were found to have been incorrectly installed, poorly selected, or undersized. There were even cases in which the installed check 6

valve consumed nearly half of the head generated by the pump! Considering the huge number of check valves now in service in industry, there is an equally huge potential for cutting costs.

Hydraulically efficient swing check valves Ever since the company was founded, KSB has been designing and producing a wide diversity of valves. One particular model was known for closing so softly and reliably that it became the valve of choice for use in the exhaust systems of numerous dieselelectric submarines. Its job was to keep seawater out of the exhaust systems of snorkeling subs. So what could have been more logical than to use SERIE 2000 check valves, with their dual plate valve disc, for less spectacular applications, too? The robust, maintenance-free valves have one-piece cast bodies with high mechanical strength and excellent corrosion resistance. Their spring assembly ensures reliable seating in situations where gravity alone would not suffice. This type of valve can be installed horizontally or vertically with no special tools required. A wide spectrum of materials allows service at temperatures between -196°C and +538°C. Their main merit, however, is their low pressure loss coefficient. The valve disc opens stably even at very low flow velocities.

Tests document high savings potentials In order to closely analyse the opening behaviour of SERIE 2000 valves, extensive tests were performed on one of KSB’s own test stands. The basic goal was to examine which kind of check valve – dual plate check valve or lift check valve – is most suitable for which kind of application. Both types were therefore tested in diverse situations. In the first test set-up, the technicians installed a lift check valve with no flow stabilisation section. The results agreed with practical field data. At minimal volume flow, the opening behaviour was unstable, and the valve began to chatter. At maximum flow, the spring vibrated strongly due to the high velocity of flow through the valve. Even the subsequent installation of a flow stabilisation section failed to improve that behaviour. In the second setTest set-up for examining up, the technicians the behaviour of check installed a SERIE valves in combination with 2000 dual plate check valve with, variable speed pumps

and then again without, a flow stabilisation section. This time, the observed opening behaviour remained stable, even with the valve in a partially open position, and there was no chattering like in the case of the lift check valve. Any unsteady behaviour of the dual plate valve discs was remedied by installing a flow stabilisation section. Under low flow conditions, the lift check valve remained very unsteady despite installation of a flow stabilisation section. Consequently, such valves should only be installed in cases where space constraints leave no room for any other choice, because its unstable opening behaviour can, under certain circumstances, result in a very high rate of wear. Nor is this kind of valve inherently suitable for use with a frequency inverter. This is also evidenced by a comparison of head losses calculated for both types of valve. The individual loss coefficient, , of a wafer-type lift check valve is approximately 4.5. With a SERIE 2000 valve, the situation is intrinsiccally more favourable, because there is no change in the direction of flow in the valve, so its value, at 0.4, is much better. This can also be demonstrated by way of the head loss, Hv, as calculated according to the following equation. DN 200 mm pipes were selected on the basis of assumed flow velocities of v = 1 - 1.5 m/s on the suction side and v = 2 - 2.5 m/s on the discharge side. Applying these data, the equation

yields 1 m as the head loss attributable to the lift check valve. The same equation yields a head loss of just 0.08 m for a SERIE 2000 valve. Depending on the application in question, this could mean that a smaller pump could be installed. To ensure stable, vibration-free behaviour of the closing elements, though, even dual plate check valves need a flow stabilisation section measuring about 5 x DN. This helps ensure smooth and energy-efficient pump operation under any set of load conditions.

Conclusions drawn It pays off to take a holistic view of the valve, the pump and the frequency inverter as a system. The cost of installing a new valve redeems itself very quickly. Of course, optimal matching of pump and valve is not the only way to reduce energy expenditure. No matter which measures are taken, though, the decisive factor is to ensure that the system is designed to match the operating point.

A guide to selecting the right float switch for your application When selecting a float switch for a liquid level sensing application, a number of factors need to be considered, including float switch and gasket materials, physical arrangement, electrical ratings and cable type, says Simon Dear of Cynergy3 Components. a good indication of the suitability of the various float switch materials in a wide range of liquids. For some process liquids, it may be necessary to obtain a sample float switch in order to test the compatibility.

Electrical

horizontal/side mounting type normally has a fixed housing, which passes through the sidewall of a tank, with a hinged float attached to the fixed housing. Vertical mounting types normally have a fixed vertical stem, which is installed through the top or bottom of a tank, along which slides a cylindrical float.

Many industrial processes require devices that are able to sense the level of liquid stored within various types of tank or chamber. The signals from these devices may be used to control the production process or to provide indication of the status. One of the most reliable, well-proven technologies for liquid level sensing is a float switch. This type of switch comprises a magnet contained within a float, as well as a magnetic reed switch contained within a fixed housing. The movement of the float, due to the changing liquid level, will cause the reed switch to operate (i.e. close or open) at a particular level. This tried and trusted technology is based on a relatively simple design that offers long term reliability without the need for the user to calibrate the switch. Whilst there are different methods available for selecting the right float switch for a particular application, the main factors to consider include the following:

Physical arrangement and style The choice of styles that may be suitable for an application will depend on the physical arrangement of the tank, the available mounting positions and whether access is available to the inside of the tank. The main styles are horizontal/ side mounting and vertical mounting. The

Another important consideration is whether a build up of deposits from the liquid on the float body is likely to occur. These deposits can, over a period of time, accumulate to such an extent that the float switch can fail to operate. Whilst particular types of float switch have been developed to limit the effects of this build up, the experience and knowledge of the switch manufacturer is also critical here.

Material selection It is critical to select a float switch that is constructed from the right materials that are compatible with the liquids and temperatures of the particular application. Component damage as a result of incorrect materials selection can ultimately cause failure of a float switch, which may have severe consequences. Typical float switch materials include:

Nylon: suitable for many oils, diesel, organic chemicals and MEK-based printing inks. Polypropylene (PP): suitable for many acids and alkali, detergents, inorganic and organic chemicals, oils and water. Polyphenylene sulphide (PPS): suitable for many of the more aggressive chemicals and higher process temperatures, up to 120ºC.

It is important to fully understand the nature of the load that needs to be switched and to ensure that the float switch is capable of handling this load. The electrical ratings, which most manufacturers provide in their float switch specifications, are for purely resistive loads. Any loads that have either inductive or capacitive components should have the appropriate contact protection measure applied.

Cables In applications where aggressive liquids may spill onto external wiring, it is important to specify particular materials for the cables used to connect to the float switches. There are standard, UL-approved cable types for the various float switches, as well as high temperature, low smoke zero halogen (LSZH) and other specialised materials.

Custom engineered float switches The operating environment is critical to the choice of float switch. A water tank for an industrial process may only require a simple plastic float switch. However, if the application is in a hazardous area, for example, a petrochemical storage tank where flammable gases, vapours or dust are present, a stainless steel, explosion-proof float switch will be required. Over the years, we have custom engineered many variants of its float switches to match particular customer requirements in a wide range if industry sectors including oil, gas & petrochemicals; food and beverage; chemicals and pharmaceuticals; water and wastewater; and process manufacturing. These include float switches for all types of environment, including industrial process control, safe areas, intrinsically safe and hazardous areas (ATEXcertified), as well as WRAS-approved switches for drinking water applications.

Buna/Nitrophyl: suitable for many oils, diesel, petrol and water (non-potable applications). D300 foam (PVC): suitable for most hydraulic oils and many chemical solutions. Stainless steel: suitable for most medical and food applications, chemicals, hydraulic fluids, fuel oils and applications with process temperatures up to 135ºC. Selection of the most suitable materials for both float switch and gasket can be made by referring to a ‘Chemical Compatibility’ table. These tables provide

REACH:

By Dr. Dieter Reiml, Certified REACH-Multiplicator at TÜV SÜD Industrie Service GmbH

Time is running out The wave of registrations is now reaching small and medium-sized companies too. The EU’s REACH Regulation obliges all manufacturers and importers of chemicals above a quantity of 1 t/a to register them by June 2018 with the European Chemicals Agency (ECHA). This is a tight time frame for small and medium-sized companies because the requirements are very complex. External service providers like TÜV SÜD can relieve the pressure on companies and prevent serious errors in the registration process. The motto of the REACH Regulation is unmistakable: “No data, no market”. Chemicals with an annual production or an import volume of one metric ton or above must be registered by the end of May 2018. This third registration phase now affects mainly small and medium-sized enterprises that manufacture or import chemicals. Anyone who cannot comply with this deadline will have to cease production or import and will no longer be allowed to put the substances on the market within the European Union.

Many a small or medium-sized enterprise is still shying away from getting to grips with the REACH Regulation – after all, the deadline is still five years away. This way of thinking entails risks due to underestimating the complexity of the registration process and the time and effort it requires. There are often not the staff resources and the IT infrastructure necessary for the registration process. Even when the registration dossier is submitted on time, there is still a threat that the marketing rights will be withdrawn if the data quality is poor. As delays or errors during registration can be vital to the company’s existence, the REACH experts recommend starting the necessary preparatory work right now. First and foremost, it should be borne in mind that REACH is not only about the technical implementation of legal obligations but also about economic and financial aspects.

Increased documentation effort REACH places high requirements on documentation which can involve a considerable amount of in-house effort and expenditure. The registration dossier for quantities above 10 metric tons per year must additionally contain a Chemical Safety Report (CSR). The safety-relevant information and protective measures must be listed in this dossier for all intended uses of the substance. This means that the CSR can easily grow in size to a hundred pages or more. In this case, it is not only the manufacturers and importers but also the downstream users who are being required to comply. There are new obligations ahead of them. They must not only comply with the usage conditions specified and implement risk reduction measures but they are also required to help shape these measures by providing feedback and actively participating in discussions. For their part the users are therefore required to provide information to the manufacturers and importers and in this way to contribute to continuous adaptation of the safety data sheets. If the chemicals are exported to EU countries, the safety data sheets must additionally be translated into the relevant languages. The exposure assessment can also cover more than a hundred pages. This must always be prepared if the substance is classified as hazardous. The document must contain answers to the questions regarding the potential risk of a chemical, how great this specific risk is and what measures will be taken to protect the environment, consumers and employees. In this case, the substance’s entire life cycle from manufacture to disposal or recycling must be taken into account.

Cooperation in the SIEF takes the pressure off SMEs It is not always clear at present whether the registration of a chemical is appropriate from an economic point of view in view of the high expenditure. So companies should check

Process Industry Informer September 2013

first of all whether the substance will still be relevant for marketing in 2018. It should also be clarified whether the chemical will be produced or imported in the tonnage band above one metric ton per year at that time and will therefore be subject to registration. If this is the case, then even small companies should appoint a responsible person who coordinates all activities for planning and managing the REACH process on schedule. The most important building block is active participation in what is referred to as the Substance Information Exchange Forum, SIEF for short. All manufacturers and importers of a substance that is to be registered come together in the SIEF to exchange information about substance properties, uses and hazards as well as cost sharing. The aim of this is to prevent the repetition of studies and duplications when registering. As SMEs generally function as co-registrants, this amalgamation reduces both the effort and the costs for registration. On the other hand, participation in the cost sharing process is essential. However, the need for communication within the SIEF should not be underestimated. If a joint chemical safety report (CSR) is prepared, the co-registrant must ensure that it supplies the leading registrant with all the relevant information about the uses it has identified. Otherwise it must either prepare its own CSR or forego the use.

The most frequent sources of error The first two phases of the REACH implementation have been completed since the end of May. During evaluation of the dossiers submitted, the European Chemicals Agency (ECHA) discovered that in some cases the data were inadequate. According to the Association of the Chemical Industry (VCI), the ECHA is considering whether the registration number for a chemical should be withdrawn in such cases. As a result, it would no longer be permissible to market the substance within the EU – with all the economic consequences for the company concerned. REACH experts, such as those at TÜV SÜD, have identified some of the most frequent sources of error in the registration process. If communication in the SIEF is not monitored precisely, then in practice the wrong substance might be registered. The registration is therefore invalid. It is also often forgotten to list every use of a substance explicitly. Yet another stumbling block: although the ECHA’s detailed ‘guidance documents’ provide valuable aids and explanations about the REACH process, they are not legally binding in themselves. Anyone who takes only these documents into consideration when preparing the dossier is not necessarily acting within the law. In some cases, important information provided by the ECHA has also been overlooked because this body only communicates via its own data processing system REACH-IT. In other cases, it was forgotten that the dossiers also have to be kept up-to-date after registration and to this end must be updated continuously. For example, if the substance’s use changes, this must communicated along the entire supply chain after registration. And perhaps the most serious error of all: the REACH process is simply started too late.

Medium-sized enterprises initiative is expedient The European Commission reduced the registration fees for SMEs in March. Although this takes the financial pressure off the SMEs, it makes no difference at all to the level of administrative effort and the associated demands made on staff resources. External support can resolve these bottlenecks and prevent delays and errors during the registration process. For example TÜV SÜD’s small and medium-sized enterprises initiative, as a REACH service specifically for SMEs, will ensure reasonably-priced and timely registration of chemical substances. The companies’ own employees will have no need to get to grips with either the complex REACH Regulation nor the relevant data processing systems IUCLID and REACH-IT.

Safety engineering company Smith Flow Control has manufactured a custom-built operating panel which enables a client to control a sequence of actuated valves. The operating panel can be used in a wide variety of applications that involve the use of actuated valves, for example to launch or receive a pig. The panel works as a communication and proofing system to improve efficiency and safety. A typical application often includes two interlocked key units to isolate power to the panel and ensure a specific sequence of operation. Using the panel, the operator can select to close the valves. Red LED lights prove that the valves have reached their fully closed position. When all valves are closed, the operator can isolate the panel by removing the ‘A’ Key. The ‘A’ key is entered into the solenoid key unit and only when the SAS (safety and automation system) confirms all valves are closed, a permissive signal is sent to energise the solenoid and release the ‘B’ key. This allows the operator to safely continue the mechanical interlocking sequence, for example, to manually unlock a pig trap door to load or unload a pig. The panel has been designed with the operator and environment in mind, making it easy to use and robust. It is made to support applications in the most aggressive environments, suitable for temperatures ranging between -40 to +55 degrees Celsius (-40 to +131 degrees Fahrenheit) with an antireflective coating that eliminates glare. The panel is designed to meet strict safety guidelines and regulatory body requirements. It is made using 316 Stainless Steel and conforms to Zone 1 Ex de classification and protection class IP66. It also boasts a compact design and can be used in weight restricted and space-limited areas.

CO2 Gas Hazards in the Brewing Industry The hazards associated with CO2 in the brewing industry are well known, yet people still die needlessly every year in tragic and completely avoidable accidents in breweries. Just last year in Germany, which has a good safety record, two workers died in separate incidents at the same brewery. Chris Wilson, Crowcon’s Senior Support Engineer, discusses these incidents and explains how they could have been avoided by following the right CO2 gas safety procedures. In the first incident, the owner was found dead with his head and torso in a beer mixing tank. It is thought that, after bottling and subsequent cleaning, the owner had leaned in to check the container and was overcome by CO2. 10 months later in the same brewery a worker was found dead in a pressure tank used to recirculate wheat beer. He had probably forgotten to fit a yeast plug and had leaned into the tank – which was already pressurised with CO2 – to fit one. He was found up to his hips in the container and had been poisoned – probably in seconds – due to the high concentration of CO2. Both these accidents demonstrate the extremely hazardous nature of CO2 and how quickly one can be overcome by its deadly properties.

Properties and effects of CO2 CO2 is extremely hazardous and can kill in two ways: either by displacing O2, leading to rapid asphyxiation, or as a toxin in its own right. Exposure to as little 0.5% volume CO2 represents a toxic health hazard, while concentrations greater than 10% volume can lead to death. Because CO2 is completely odourless and colourless there is no physical indication of danger until it is usually too late. CO2 is a by-product of the fermentation process and, because the gas is heavier than air, it collects at the bottom of containers and confined spaces such as tanks and cellars and can even spill out of fermenting tanks and sink to the brewery floor, where it forms deadly, invisible pockets. In fact, CO2 is a hazard throughout the brewing process, right through to packaging and bottling.

Safety precautions Fermentation tanks, beer mixing tanks, silos and other confined spaces in the brewing industry are easily accessible – it is rare for them to be fitted with safety interlocks. For this very reason rigorous safety systems should be in place and always adhered to. Employers must assess the risks these areas pose to their employees and endeavour to prevent them. In most cases, both the assessment and the safe working system will require testing of the atmosphere with gas detection equipment. As a rule, entry should not be routine and should only be carried out if absolutely necessary. However, if entry is necessary – for example for an inspection or to ensure cleaning has been carried out correctly – suitable safety procedures must be followed. Firstly, CO2 from the space must be completely removed. This can be done by discharging all the fermentation and pressure gasses directly into the open air using a ring main system. If this is not possible due to the layout, the CO2 must be manually extracted and safely diverted. Prior to entering a tank or other confined space, a ‘release measurement’ of CO2 must be taken using a suitable CO2 monitor. This is the only reliable method to check whether the CO2 concentration is actually at a safe level. The measurement must be taken by a qualified person, usually by lowering the monitor into the chamber and leaving it there for several minutes. It goes without saying that any monitoring device must be durable, reliable and regularly calibrated and tested.

Protecting the worker entering a confined space Anyone entering a tank or other confined space must also be equipped with a suitable gas detector. If a certain CO2 concentration is exceeded the device will go into alarm

mode with both audio and visual alarms. Generally, at a CO2 volume of 0.5 % by volume, a pre-warning is set off; at 1 to 2 % by volume the main alarm is activated. With most devices other alarm thresholds can be selected with the aim of avoiding the alarm sounding too frequently and simultaneously ensuring the safety of the person working in the container.

CO2 gas detector types Both portable and fixed CO2 detectors can be used for CO2 monitoring in breweries. Fixed systems typically comprise one or more detector “heads” connected to a separate control panel. If a detector reads a dangerous CO2 level, extractor fans are automatically triggered and sirens or visual beacons can also be activated to warn workers to vacate the area. This sort of installation is suited to larger spaces like cellars and plant rooms. However, much confined space work in the brewing industry takes place in more restricted areas like fermentation tanks where fixed detectors cannot be installed. This means compact portable units are required. Ease of use, with one button operation, should be the norm when it comes to portable detectors. This means minimal training is required while increased safety is ensured. Combining one or more sensors with powerful audible and visual signals to warn when pre-set gas levels are reached, compact portable detectors are easily carried in a confined space, ensuring that pockets of high CO2 concentration are not missed. Certain features should be expected in every portable CO2 detector. Clearly, lifesaving tools for demanding environments must be as tough as possible, with reliable electronics housed in impact-resistant casings. While the need to leave gas sensors exposed to the atmosphere means that no instrument can be fully sealed, a high degree of protection against dust and water ingress is essential. Toughness notwithstanding, a well-designed detector will also be light and compact enough to wear for an entire shift. Finally, because of the difficulties of working in a cramped space, perhaps under poor lighting, instruments should be easy to use. No matter how advanced a detector’s internal architecture or data management options, personnel in the field should be faced with nothing more daunting than a clear display, simple, one-button operation and loud/bright alarms.

Conclusion Not taking the risk of CO2 seriously has led to many unavoidable deaths. If all the safety procedures described above are observed, the risks of dealing with this colourless, odourless and tasteless gas can be significantly reduced.

Wanner International has introduced a range of heavy duty, seal-less diaphragm bypass valves that are reported to provide accurate, repeatable smooth response without causing “chatter” in bypass lines. The Hydra-Cell C62/C63/C64 Series offers accurate, repeatable, smooth operation with minimal pressure surge and “chatter-free” bypass. Available in a choice of 316 stainless steel, Hastelloy or brass body with PTFE or Viton ‘O’ rings and PTFE diaphragm these valves are ideal for use in systems pumping corrosive or dirty liquids. They can be used with any positive displacement pump with flows up to 151 lpm. The Hydra-Cell Valve design is simple: a tapered plunger with an attached diaphragm. When excess pressure overcomes the adjustable spring pressure on the plunger, the plunger lifts off the valve seat, allowing fluid to bypass and reduce system pressure. When a system discharge is completely closed – such as a closed spray gun, closed valve or plugged nozzle – the Hydra-Cell Valve bypasses the total system fluid flow. Thanks to their immediate response these valves also balance system pressure for multiple-gun operations. Hydra-Cell Diaphragm Bypass Valves can be serviced in place, without removing any fittings or plumbing, simply by removing the top of the valve body and replacing any worn internal components.

Keep up with ATEX and stop dust fires Most of us are aware that devastating explosions and fires can be caused by explosive gases and vapours but are perhaps not so aware that fires caused by dust can be equally as destructive. This has now been addressed by the recently defined ATEX zone 20 to 22 dust conditions. To avoid liability, companies are advised to use suppliers and repairers who correctly certify machines to comply with the new legislation, says ERIKS. The trend for many years now has been to tighten up Health & Safety in the workplace. Engineering companies have a responsibility to their employees, and engineers themselves have a responsibility for their own safety and those around them. Statistics at a recent H&S course illustrated the point that over 90% of all industrial accidents are attributed to complacency. At H&S courses, attendees are encouraged to think about what they would miss most if they lost their sight or the ability to walk, even temporarily, and suddenly the wearing of safety glasses

doesn’t seem such a chore. Understanding and appreciating the risks to workers and establishing the most effective and efficient practices by which to minimise them can be a complex task but one that looks set to become more urgent than ever. A new Health and Safety Executive (HSE) cost recovery scheme for inspections and interventions is now in force under the Health and Safety (Fees) Regulations 2012. These Regulations put a duty on HSE to recover its costs for carrying out its regulatory functions from those found to be in material breach of health and safety law. A material breach is defined by the HSE as a contravention of health and safety law that is serious enough to require them to notify the person in material breach of that opinion in writing. When it comes to machine safety, legislation is particularly thorough and far reaching. Since moving machinery is capable of causing fire in hazardous environments, designers and engineers have invested a lot of time and energy in trying to minimise the problem. The fact that so much is at stake as a consequence of failure has driven the development of a range of tools and practices to defend the workforce from such hazards and their consequences, and routine maintenance procedures have enabled engineers to minimise the development of faults. Indeed, components themselves are continually being refined and upgraded to prevent, or offer greater resistance to, hazardous environments. To achieve a consistent and efficient management of plant safety, an awareness of ATEX-approved components is vital and, in many process and manufacturing applications, plays a major part in enabling operators and maintenance engineers to ensure that plant is observing all current legislation. Compliance with ATEX has always been a challenging, step-by-step process. Even in traditional ATEX industries, such as petrochemical processing facilities, there have been some challenges that have proved particularly hard to surmount, such as providing sensors that can perform reliably in the presence of the high pressures found within applications such as wellhead automation, gas distribution and gas compressors. In these applications, safety is critical and component failure could result in a serious accident. These hazardous conditions present complications to engineers, not only in ensuring safety but also in carrying out installation and replacement of components, which can be extremely difficult. However, solutions have been developed and engineers in these applications are now well used to conformity. Now maintenance operatives in a much wider section of industry need to make sure that repairs and maintenance meet the latest ATEX dust regulations.

Newly defined regulations determine the need to select suppliers more carefully… The recently defined ATEX zone 20 to 22 dust conditions present a new challenge and companies are advised to use suppliers and repairers who correctly certify machines, if they are to avoid liability. Most of us are aware that devastating explosions and fires can be caused by explosive gases and vapours but are perhaps not so aware that fires caused by dust can be equally as destructive, and this is reflected by the new legislation. The regulations have

Process Industry Informer September 2013

been influenced by the fact that there have been several large explosions investigated in recent years, in areas such as crop storage, food processing, coal processing and plastics that have been attributed to dust, either atmospheric or settled. So, with both these dust conditions covered by the regulations, and with the dangerous substances and explosive atmospheres regulations (DSEAR) 2002 also requiring employers to control the risks from fire and explosions, it is time for engineers to be sure that they understand what constitutes a risk to safety and consider carefully how to address it. Key to achieving conformity is to consult a leading supplier with expertise in a wide range of parts and components such as motors, belt drives and couplings – all of which are included in the regulations. Any party with responsibility for certification of supplied equipment, including product manufacturers, can be held legally responsible for accidents due to non-conformity with the new directives. The newly defined zones will affect many new operations, so if you are in any doubt about your responsibilities, conformity or the best way to achieve it, you should talk to a supplier who understands your industry, the legislation, and the machinery to which it applies. ATEX compliance – indeed, plant safety at large – has thankfully become an established part of the business processes for most industrial and manufacturing companies. It has moved beyond a simple assessment of risk to comply with and exceed the requirements of legislation and the welcome growth of this more responsible culture will make it easier for most firms to adjust. Indeed, the more enlightened companies are already recognising that by getting in line with legislation as early as possible, they can both comply with legislation and improve their productivity and profitability, while also presenting an impressive set of credentials to their customers.

Don’t take chances… Understanding and appreciating the risks to workers and establishing the most effective and efficient practices by which to minimise them can be a complex task. So, it may be advisable to work with a partner such as ERIKS that can help you to cost-effectively and efficiently review and renew your plant to comply with the regulations. Take, for example, the requirements for motors that operate in hazardous areas. The ATEX labelling scheme provides a vital indication of the level of protection offered and the zones in which the motor is suitable for use but the judgement as to whether a repaired motor remains ATEX-compliant is more complex and may require help from a specialist. To maintain safety, operators must be sure that a repaired motor is as safe as a new one, so it is important to enlist the help of a partner that offers an accredited repair service. The recently defined ATEX zone 20 to 22 dust conditions present a new challenge but also an opportunity to maximise safety and minimise plant shutdown, which will benefit people as well as profitability.

instrumentation

ELECTRONIC RELATIVE HUMIDITY (RH) INDICATOR Brownell has introduced an Electronic Relative Humidity Indicator as an alternative to paper and chemical colour based indicators. The new Electronic Humidity uses a polymer humidity sensor combined with a thermocouple to provide a digital display reading of relative humidity, ambient temperature and dewpoint. The operating range of the electronic relative humidity indicator is 5 to 80%RH, -20oC to +15oC dewpoint and -20oC to 60oC temperature. The electronic RH indicator removes the uncertainty associated

with temperature by converting the readings to dewpoint. Dewpoint is an absolute measure and is not influenced by temperature. Dewpoint indicates the temperature to which the system or instrument can be cooled before condensation (or frost) will occur. This qualifies dewpoint as a quality control standard for specify an operating performance for systems and instruments. The Electronic Indicator is mounted in a robust IP67 enclosure with a membrane press switch to activate the three readings in sequence.

MULTI PIN CONNECTORS

enclosures

New crimped RITTAL TOPTHERM INVERTER contact design CHILLER – IMPROVED launched for PRECISION AND EFFICIENCY Marechal’s multipin connectors MARECHAL has further enhanced its range of multi-pin connectors by offering the user a new design of crimped contact. Quick and easy to use, these connectors are designed for the transmission of power, signal and data in one connector thus providing greater operational flexibility whilst reducing the bench time required to make them off. Comprehensive multipin range The new crimped contact design is available with up to 37 contacts in both the IP66/67 DSN and DXN ATEX types as well as the industrial IP54 DS versions. The more compact industrial PN12C and ATEX PXN12C versions offer 12 contacts. They are all rated to 10A at a maximum of 415V (PN12C, 500V). Each socket and plug is supplied with the requisite number of contacts in multiples of 13. Socket and plug contacts can be removed from the housing using the tool supplied, crimped and then re-inserted into the socket/plug using the same tool. Patented safety technology MARECHAL’s DECONTACTOR™ offers a patented design including the plug release latch on the socket. When pressed the plug is ejected from the socket to a parked position, off load and providing visible isolation of the equipment in use. Contacts are silver-nickel tipped and spring loaded for better electrical performance. Whilst being crimpable the new contact design can also be soldered if preferred. The DECONTACTOR™ offers MARECHAL’s on load make and break capability for additional user safety. Reducing maintenance costs Replacing hard-wired connections in junction boxes with a quick release DECONTACTOR™ reduces plant downtime or conversely, speeds up maintenance time by being able to isolate equipment in seconds. Whether washing down, re-arranging machine locations or making repairs, downtime is substantially reduced without compromising user safety. Long-term reliability Contacts are housed in a choice of robust casings – polyester or metal - with suitable accessories available for each type. Both casings resist corrosion and vibration whilst offering over 2000 mating cycles. Shock resistance is IK08 for poly and IK09 for metal housings with both rated to IP66/67 for water and dust ingress. The ingress seal is achieved automatically as the plug is inserted into the socket or socket lid closed. The all-round quality of the DECONTACTOR™ multipin range is the reason it is installed in so many diverse industries including food & beverage, shipping, chemical, waste water and oil & gas. For durable, space-saving and simply assembled multipin connectors take a closer look at the MARECHAL range.

With the focus on flexibility, operation an security Rittal’s complete range of Top Therm chillers now has a reduced depth of 605mm, increasing the number of enclosures to which it may be bayed. The condenser fan, relocated to the roof of the unit, provides an optimised thermodynamic performance and an incorporated condenser protection grill minimisies the risk of damage during transit and installation. The temperature of the chilled water supplied for enclosure cooling is not as critical as that used in process cooling. Spindle cooling demands the cooling medium is supplied within a tolerance of ± 0.5 K, to guarantee the necessary accuracy in processing, otherwise the thermal expansion of the components will cause inaccuracies in the machined workpiece. Chillers are generally governed by a two-point control system, i.e. turning the compressor on and off as the temperature of the cooling water either rises above or falls below the maximum and minimum permissible limits. However, it is not possible to control within the small hysteresis required for machine cooling using this method as the frequent switching would adversely affect component life.

Rittal’s new TopTherm Inverter Chiller incorporates a variable speed compressor powered by a brushless DC motor, the speed of which is controlled by an inverter, to deliver the cooling medium at a temperature with the required accuracy. This technology, in conjunction with other optimised components in the refrigerant circuit, an electronically controlled expansion valve and energy efficient electronically commutated (EC) fans, has culminated in a range of chillers with a capacity range of 2-19.5 kW, a chilled water temperature tolerance as low as ± 0.2 K and an impressively high energy efficiency ratio (EER) of up to 3.3.

RiPOWER FORM 4 DISTRIBUTION SYSTEMS Rittal Ri4Power Form 4 distribution systems achieve internal compartmentalisation by utilising metal shielding that segregates the busbar systems, functional units and terminals. To increase flexibility several new wiring systems are available as an option. The new wiring systems facilitate vertical and horizontal cable routing whilst ensuring internal Form 2-4. Vertical cable routing and pre-punched cut-outs are provided in the mounting brackets for compartment dividers, which can easily be knocked out and used to install a vertical wiring channel. Horizontal cable routing occurs behind the front trim panels. This entails fitting a wiring trim panel suitable to accommodate a wiring channel which, at the same time, conceals the busbar system.

SET POINT GENERATORS

IS loop powered 4/20mA set point station reduces cost BEKA associates have introduced a new intrinsically safe panel mounting loop-powered 4/20mA Set Point Station [set point generator], which is ATEX and IECEx certified for use in all gas and dust hazardous areas. Enabling manual set point adjustment from within a hazardous process area, it incorporates a bold five digit display which may be calibrated to show the engineering variable represented by the 4/20mA current, plus a thirty one segment bargraph showing the output current. The new BA427E generator which is backwards compatible with the earlier BA405C, has additional features including five pre-set outputs, an extended temperature range, an easy to change scale card and a lower list price than its predecessor. For general purpose applications, the new BA627E offers the same additional features. Both models have a 96 x 48mm DIN enclosure with an IP66 front panel and are available with a factory fitted green backlight which may be loop or separately powered.
