The Changing of the Numbers

48 Company Profile: Andrews Sykes

Articles about refrigerants are the most popular on the ACR Journal website. Quite rightly too. They are at the heart of the cooling industry in helping to keep products and people at the right temperature.

50

Until quite recently, articles about R22 were the most read refrigerant articles on our website as the phase-out came into force in January. Readers needed information about the impact of the legislation on their customers’ air conditioning systems who had systems containing R22.

A few months ago, R32 was an interesting topic for the future. But, until there was the infrastructure and product range to support it, it was just a matter of interest, if our website is anything to go by.

That has now changed. Interest in R22 has waned.

Readers have shifted their interest to R32. The top articles online now focus on R32.

But, how does this ‘change of numbers’ translate into business? How many contractors installing R32-based systems?

I would like to hear from you if you are.

Finally, we have an announcement to make about the National ACR & Heat Pump Awards. Turn to pages 14 & 15 or visit our website for more details: www.acr-heat-pumps-today.co.uk/Awards/

Four HFO Refrigerants Launched by Honeywell Honeywell announced the launch of four low GWP HFO refrigerants in April, adding to their F-Gas compliant range of products.

The HFO (hydrofluoro-olefin) refrigerants will be used in supermarket, chiller and air conditioning systems, and are part of Honeywell’s Soltice® range. The company aims to make it easier for industrial customers to move over to using alternatives to high global warming potential refrigerants.

Honeywell spokesman, Julien Soulet, who is part of the manufacturer’s fluorine team said,“Each year, the world uses more than 100 thousand tonnes of refrigerant, enough to keep food fresh in 240,000 supermarkets and to cool more than 300,000 commercial buildings.”

See the summary table below to understand where Honeywell’s HFO refrigerants apply:

LG Opens New Factory in Vietnam LG Electronics opened its new factory in Vietnam in April on its Haiphong Campus near Hanoi.

The 262,000 square feet building will house the factory making its air conditioning products, as well as TVs, mobile phones, washing machines and in-car entertainment systems. The products will be shipped nationally and internationally.

Over 400 people came to the opening ceremony including the country’s President and Korea’s Ambassador, Dae-joo Jun. The new factory is part of a £1 billion investment by LG and its suppliers over the next 15 years. LG’s two current plants in Vietnam will move into the Haiphong Campus which gives the company room to grow.

The factory’s location near to a port will make it easier to transport its products and parts in and out of the country quickly. Also, there is a well-educated workforce in the area, and government support.

“It’s quite appropriate to be marking this occasion on the 20th

NEWS.indd 6

anniversary of our entry into Vietnam,” said LG Electronics CEO Bon-joon Koo. “We will make every effort to make this cooperative venture a success so that our new Haiphong Campus will play an important role in LG’s global manufacturing strategy.”

EU F-gas regulation. The end for high GWP gases.

The new EU f-gas regulation (517/2014) comes into force on 1.1.2015. It will quickly restrict the use of high Global Warming Potential gases such as R404A, R507 and R422D. 3 choices are available to you: → Continue using your existing gas but expect to face potential product shortages and cost increases → Convert your existing equipment to run on an alternative “retrofit” refrigerant with lower GWP → Change your refrigeration equipment to use a different gas such as HFO or natural refrigerants.

BOC can help you understand the impact of phase-out on your business, develop the best plan of action and support your chosen path by providing you with the gases you need – when and where you need them.

Delegates on one of the first courses

New £6.5 million UK HQ for Eberspächer The German maker and supplier of heating and air conditioning systems for the automotive, construction, and marine markets opened its new, £6.5 million UK headquarters in Ringwood recently.

CDL Opens New ACR Training Centre in Scotland Toshiba Air Conditioning distributor, CDL, recently opened a new training centre in Glasgow recently to serve its Scottish installers.

CDL’s training centre is in College Milton, East Kilbride and boasts a full set of Toshiba courses to help installers learn practical and theoretical skills on installation, commissioning and problem-solving.

Also in its training portfolio are courses on F-Gas regulations to help contractors understand the changes, how it impacts them and their end user customers. Delegates on courses will get their hands on working equipment including Toshiba’s SMMS mini-VRF. Darrel Birkett, managing director, said: “One of the biggest constraints on the growth of the air conditioning industry is the availability of skilled engineers. As a successful and growing distributor, we have a responsibility to help grow the next generation, and make sure today’s staff are fully up-to-speed, on the technology, the environment and the regulations. That way everyone benefits.”

Find out more about training courses in the new training centre here: call 01355 234776 or via CDL’s Sunderland headquarters on 0191 5496964.

The 150 year old German company opened its first UK office in 1977 but has now moved its three other UK offices into the new site.

Vince Lee, Eberspächer UK’s Managing Director, explained: “We needed to retain the particularly unique skills of the current workforce so waited patiently for this site to be developed in Ringwood.”

He continued,“Now, with our new facility, we have an unprecedented opportunity to increase production, create new jobs in the area and bring the latest technologies and innovations to life.”

At 5,276m2, the new site is three times bigger than its previous sites combined. The new HQ has a state-of-the-art climatic chamber, boasting a temperature range of -30°C to +60°C. This will help them to develop new condensers and evaporators which will come off the production line in April.

US HVAC Market Set to Reach £13.7 Billion by 2019 The heating, ventilation and air conditioning (HVAC) market is forecasted to increase by nearly 7% a year between now and 2019, according to a report by the Freedonia Group.

The growth rate in this period is nearly double that seen between 2009 and 2014. The rise is driven by investment in construction spending, particularly in the refurbishment and repair sectors.

Furthermore, the report forecasts that demand for highly sophisticated and technical HVAC solutions will contribute to the growth.

NEWS.indd 8

Tax incentives to install more efficient domestic HVAC systems ended in 2014 which could mean less demand in this market. The report anticipates that more than a quarter of HVAC equipment shipments will be imported systems by 2019.

However, the impact of refrigerant regulations (e.g. R22 phase-out) and more efficient equipment will mean that demand will be strong. Also, heat pumps which can provide both heating and cooling for commercial properties will be in demand where energy efficiency is important.

Beijer Ref Expands into ANZ

Beijer Ref’s expansion continues with the announcement from the air conditioning and refrigeration wholesaling business that it has bought Patton, a company with operations in New Zealand, Australia, India and Thailand.

Patton has a long history in the refrigeration industry, having started in 1923. The company now turns over around £31.3 million a year. The company is not only a wholesaler but a manufacturer too of its own brand products.

Most of Patton’s business comes from New Zealand and Australia. But, its sales are growing in India where the country’s refrigeration infrastructure is developing. Its Thai manufacturing business makes and sells its products through the Middle East, South East Asian and Australia. ”Beijer Ref complements Patton’s current product supply with several strong international brands, which are currently missing in its product portfolio.

It means that Beijer Ref, with its overall product offer, will become more competitive in these markets. In addition, we see synergies on the purchasing side as well as on the production side”,

Carrier’s New Academy Training Facility Carrier Commercial Refrigeration has opened an academy field training facility in Germany, its first in a live-store environment.

The academy officially opened 25th March at Carrier’s Research Development Centre in Mainz. It will serve as the central training site for Carrier’s service and installation technicians from across Europe, providing practical training and exercises to improve skills, while sharing best practices. Assigned technicians will be trained on specific carbon dioxide (CO2) refrigerant technologies, while supplemental local training initiatives will also continue.

“Participating in internal training activities under best-in-class conditions enables our field technicians to gain and apply the latest knowledge on how to install and service CO2OLtec®turnkey projects with the highest level of quality and reliability,” said Bart Driessens, Service Operations Director at Carrier Commercial Refrigeration Europe.

The new facility features a training room as well as an operational cold room and freezer room. A CO2OLtec refrigeration system is installed and connected with remote cabinets to create a fully operational CO2supermarket where real-time situations, such as scheduled service and other necessary repairs, can be simulated.

ACR and Heat Pump Apprenticeship Approved The air conditioning, refrigeration and heat pump industry received a boost this in April when the government approved a new apprenticeship standard for the sector.

The Refrigeration, Air Conditioning and Heat Pump Engineering Technician apprenticeship was developed by employers with the help of the Institute of Refrigeration and the ACRIB (Air Conditioning & Refrigeration Industry Board).

Skills Minister Nick Boles said:“Apprenticeships are a real success story. Through giving leading employers in your sector the power to design and deliver high quality apprenticeships we can give young people the skills our economy vitally needs.

It is big step forward for the ACR & HP industry which struggles to attract enough young people with the right skills to help it grow.

“It is critical for us as an industry that we lead the development of skills for the RACHP sector. The new RACHP Engineering Technician apprenticeship will enable our industry to support and engage with young people at an early stage in their career,” said IoR President Graeme Maidment.

“There is much more work to be done to bring this new standard to the market but we are confident that with continued high levels of support from employers, it will make an immediate and lasting

NEWS.indd 9

contribution to the future of the industry.”

The new Apprenticeship standard outlines the knowledge, skills and behaviours needed to achieve full competence in RACHP Engineering Technician job roles. The standard was developed by a group of twelve employers designated a “Trailblazer” by BIS (Department for Business Innovation and Skills). They will continue now to prepare an Assessment Plan, leading to a new Apprenticeship for the RACHP Engineering Technician, linked to Engineering Council national standards.

People who enrol in the three year course will learn to apply ‘relevant’ scientific principals and basics, coupled with work-based experience and training with real employers.

f you ask anyone what a Service Engineer or Technician is, there are always a lot of different views. But, the final word has to go to the UK Engineering Council. The Engineering Council award professional titles such as Engineering Technician or Chartered Engineer across all fields using a specific set of criteria against which an individual’s experience, knowledge and skills is judged whatever their area of work. The Engineering Technician in the RACHP sector is awarded by the Institute of Refrigeration in association with CIBSE, through our membership of the Engineering Council.

SO WHY SHOULD YOU BOTHER? In practical terms, gaining the letters ‘EngTech’ after your name will mark you out as a registered professional. It could help boost your career. It is an internationally recognised mark of your engineering skills, experience and competence and shows the commitment you’re prepared to make to your career and to keeping your skills updated in the future.

The first step towards registration is to become a Technician Member of the Institute of Refrigeration. Technician members gain access to regular practical updates and news on standards and legislation, their membership is based on holding a suitable F Gas Qualification and having at least 3 years verified experience in the industry.

Once you are an IOR member you can apply for Engineering Council registration in one of two ways.

SHOW YOUR COMPETENCE If you have a level 3 NVQ or Apprenticeship plus suitable experience the process is straightforward. You need to provide an additional portfolio of evidence demonstrating your competence and commitment to regular on-going training and your annual SES CPD Certification! Help is available to mentor applicants through each step. Fees to the IOR and Engineering Council will also apply.

Industry employers are currently working on a new RACHP Engineering Technician Apprenticeship framework that will be closely aligned to the Engineering Council standards, so future entrants to the sector will be recognised nationally with the same status as other engineering professions.

efrigeration, Air Conditioning and Heat Pumps (RACHP) industry underpins everything we do.

Refrigeration reaches in to vast range of fields, that we all in counter in our everyday lives for example without it the food supply would still be seasonal and limited to locally produced nonconsumable items; data centres would not work, comfortable living conditions and certain medical advancements would be impossible.

RACHP account for 19% of UK electricity demand or around 10% of total greenhouse gas (GHG) emissions. Last month at an EU meeting in Paris, the EU agreed to intensify reductions in carbon emission further from 2020 to 2030. This will include a further 40% GHG reduction, through much greater use of renewable technologies and a massive increase in energy efficiency.

As a big GHG emitter and electricity user, the RACHP industry will be at the forefront Adopting different ways of reducing the energy use and carbon emission for RACHP such as utilising and developing efficient innovative and low carbon technologies.

Modern refrigeration is almost entirely based on a compression and expansion refrigeration cycle. Vapour compression refrigeration is a mature, reliable and relatively low cost technology. Over the years, the design of components and equipment of refrigeration systems, such as heat exchangers, compressors, fans, pumps, refrigerants and expansion valves were considerably improved due to extended research and developmental efforts.

Anticipated improvements, however, are incremental since modern refrigeration is already near its fundamental limit of energy efficiency.

However, vapour compression is not the only cooling technology available. There are many many others, including technologies

the future that maybe familiar like absorption and adsorption refrigeration, however, there are some more obscure technologies such as Electrocalorics and thermoacoustics.

In a series of articles SIRACH will review individual heating and cooling technologies and simply describe how they work, who has been developing them. The potential benefits of application and the challenges in bringing to market. Next month we will describe Magnetic refrigeration.

SIRACH will be exploring the topic of Innovations in Heat Pumps and Cooling - The Integration Challenge. The event will focus on the “integration challenge” and latest developments and innovations in heat pumps and cooling technologies and look at the challenges that integration poses.

Presentations will include an overview and technical presentation from Arctic Circle.

The SIRACH event will also include a unique tour of Arctic Circle’s leading edge research and development facilities in the UK. Arctic Circle is well known for providing low carbon solutions to the industry through innovation in compressors, heat recovery, chillers, thermal storage and heat pumps. Delegates will be able to hear from experts on the design and manufacturing process in this unique tour.

Anyone who wants to attend this event can book online.

With an election this close, the future is already certain

S

o, it is election time, when we as a country choose the government we want – or not!

At the time of writing, if the polls are to be believed, no one party will win an overall majority and we look likely to be led by a coalition.

What that means for us as individuals remains unclear but one thing I would predict is that things will not change drastically for us collectively as the Aircon industry.

I say this because to a large degree, the future is already mapped out, with legislation both from here and from Europe, continuing to direct the way that things are heading, regardless of the flavour or colour of the next UK government.

We already have F-Gas and the Building Regulations governing the way we work and operate.

We already know that we will see the increasing impact of

energy labelling, both of buildings and of equipment, as part of the on-going drive to reduce energy use and lower carbon emissions.

We will also see an increasing pressure to reduce the use of refrigerants in occupied spaces – especially in the hotel sector and we are starting to see three real options here: ₀ We can design systems to reduce refrigerant; ₀ we can add the cost of including sometimes complex leak detection systems; ₀ or we can utilise the new systems coming on the market that use other refrigerants such as CO2 or even water as is the case with our own HVRF system.

What I do confidently predict though is that we as an industry will have an increasingly important role to play because we are the specialists who understand the need to balance internal ‘creature comfort’ with energy use and emissions.

I meet keen, fresh-faced engineers, straight out of college, and old-hands who come in for updates on things they already know like the back of their hands.

It is us collectively that are charged with making the buildings work properly once they are designed, built and occupied.

It’s our job to keep the nation cool, warm and ventilated, to enable the nation to ‘work, rest and play’ in comfort.

As a trainer, I can also see that we are continuing to develop the people with the skills to meet these challenges – regardless of whoever ends up in Number 10!

Kilma-Therm in Double Distribution Deal with Gree and World Energy Chiller and air conditioning specialist, Klima-Therm, is the new distributor for Gree’s centrifugal chillers and World Energy’s absorption chillers.

T

he deal with Korean company, World Energy, is exclusive for the UK for its absorption chillers. The chillers capture waste heat from buildings and industrial processes. The technology converts the heat in high efficiency cooling which is used in either comfort or process cooling.

Klima-Therm managing director, Robert Mallozzi said, “Harnessing waste heat in place of primary energy, such as electricity or gas, can deliver dramatic cost savings for end users, not to mention the

environmental benefits. World Energy has been active in the field for many years and is absolutely at the forefront of technology. Its reputation for excellent design and reliability is well deserved.”

World Energy’s Max Santini explained that, with their technology, customers can use heat from solar thermal, geo thermal, flue gases, waste heat from chimney, district heating, and chemical heat source fired chillers, for example.

Kilma-Therm sees a market opportunity in the UK for absorption chiller. The mandatory

move towards using renewable energy sources to contribute to energy use in buildings is driving it. The company believes that absorption technology use will grow in the near future as organisations look to use energy from waste, combined heat and power and micro-generation plants.

The UK government is encouraging the uptake of district heating, or heat networks, to provide heat and hot water to domestic and non-domestic properties.

These large scale projects often use absorption technology to provide heating and cooling.

Klima-Therm’s other UK distribution agreement is with Chinese company Gree, which makes 60 million air conditioning units and 5.5 million CAC units a year.

The agreement is to distribute Gree’s high efficiency, costcompetitive centrifugal chiller solutions used in buildings and estates that need several gigawatts of cooling capacity. Gree’s products include its variable speed centrifugal chiller and photovoltaic (PV) powered inverter chiller. These provide renewable electricity for powering cooling systems and can also feed power directly into the grid, respectively.

Mallozzi continued, “Having visited a number of their factories and headquarters in China, the quality and scale of the company is beyond impressive, it is breathtaking. After two decades of rapid growth, one in three residential air conditioning units in the world is now manufactured by Gree, an astonishing feat. Our goal is to make them as famous in the UK’s commercial sector.”

WORLD’S FIRST DIRECT DRIVEN PV CENTRIFUGAL CHILLER The world’s first photovoltaic (PV) direct-driven inverter centrifugal chiller was developed by Gree in 2014. With an outstanding COP 7.10, it can deliver energy savings of up to 40 per cent compared with a standard centrifugal chiller.

First installed on Gree’s own facility in China, the chiller contains five core technologies: PV Direct Drive Technology, Maximum Power Point Tracking Technology, Pulse Amplitude-Width Modulation Interleaving Control Technology, Power Integrated Management Technology and Ternary Communication Technology.

After being operated for a year from Gree’ s 3890 square metre PV array at the company’s R&D centre, it has saved more than 831,600 kWh of power, providing free electricity free and saving more than £93,000.

Klima-Therm is backing the launch of Gree centrifugal chillers with a five-year warranty, believed to be an industry first in UK chiller market. Tim Mitchell, Klima-Therm’s sales director, said: “It demonstrates our confidence in Gree technology, and provides a compelling additional benefit for consultants and end users.”

A BETTER WAY OF SUPPORTING

M&E Building Services on flat roofs?

Laurence James of ‘Pump House’ in Nottingham looks at how mechanical and electrical contractors are changing their views on the best practice in supporting rooftop M&E building services by favouring independent and non-penetrative support systems now widely available across the UK.

I

f you have ever been up on a flat roof where there are old existing building services insitu, it should be all too clear that the traditional manner of supporting these services is often less than ideal these days. The question now is whether these traditional methods of casting concrete plinths, building brick piers or manufacturing steelwork are becoming a thing of the past?

OLD HEAVYWEIGHTS Traditional concrete plinths require shuttering works prior to concrete pouring, with additional waterproofing layers to be added following this. With brick piers

curing times and separate trades are also required. Alternatively, steel plinths which break through the waterproofing membrane and insulation down to the structural roof can cause inherent risks themselves, such as potential cold bridging issues, and may affect current Building Regulations Approved Document Part L energy reduction figures.

It goes without saying that the time-frame and differing trades required to carry out such ‘old’ traditional detailing can have an adverse effect on the smooth running of building contracts.

Potentially, there is the risk of delay should, for example, there be ingress of water through an area of extra waterproofing detailing carried out to these plinths

LIGHTER ALTERNATIVES The problems may be compounded in that traditional practices can cause headaches for the building owner or end user in respect of future upgrading of their flat roof insulation.

If replacement of the existing building services becomes necessary, in favour of smaller, more high-efficient equipment, it can lead to the new items not fitting upon the original plinth locations at all!

It is of little surprise then that we are seeing greater emphasis on utilizing the non-invasive, independent and lightweight supporting products available in today’s market? These proprietary products are typically manufactured from mild steel strut or box sections that are hot dip galvanized to produce frameworks which support building services.

“They provide the installer with a fully flexible solution that ultimately is quick and simple to install”

Continued from page 20

The frameworks manage the imposed loading down through their polypropylene, plastic or rubber feet which are square, rectangular or round in fashion; these in-turn sit on the finished waterproofing layer or upon the insulation boards within an inverted roof design.

Since the advent of independent support systems, introduced into the UK back in the midnineties, contractors, specifiers and consultants alike are realizing that these lightweight solutions negate many of the traditional elements and overall provide greater flexibility, whilst reducing unnecessary risk of delays to the project program.

WHY CHANGE? One would suggest that the key to the rise of such products is their simplicity? Lightweight nonpenetrating solutions that can be manually positioned at the last minute, without being set within a pre-determined location dictated early on in the project works. They provide the installer with a fully flexible solution that ultimately is quick and simple to install with little, if any, training required.

As mentioned they negate the requirements for often

Pump House.indd 22

awkward and time consuming waterproofing detailing, avoiding cutting through the insulation layer causing thermal deficiencies and potential interstitial condensation complications. These independent frameworks are robust enough to manage the heaviest building services such as large chillers and packaged plant rooms quite satisfactorily.

CONSIDERING THE RISKS However, these support solutions can come with some inherent risk themselves. What with a plethora of support systems now available to purchase through many different companies within the UK, the installer should not lose sight of key considerations associated with such systems.

In the very nature that these solutions are lightweight and independent, they can be susceptible to wind loadings, particularly in exposed areas such as high rise buildings or coastal environments. Therefore guidance and, if necessary, wind loading data should be sort from the manufacturer of such systems prior to delivery.

Another factor is when heavy services, such as packaged plant rooms, large chillers and airhandling units, have concentrated loads which need to be managed to ensure the roofing insulation within the roof build up is not compromised and compressed.

Again, creditable calculations relating to foot pressures, leg

reactions and roof loadings ought to be a prerequisite, and a sound knowledge of modern-day flat roof designs and insulation types should be mandatory to ensure there are no inherent damaging effects to the roofing build-up post the installation of framework and plant on top.

SUPPORT FOR THE SUPPORT Above all when the consumer makes their selection on which supporting system to purchase, they should ensure they are automatically receiving the technical support, long term experience and professional advice by the product manufacturer.

The manufacturer should automatically give consideration to all aspects associated with the support system namely, the roofing build-up beneath, the imposed roof loadings and foot pressures and wind load management.

Maintenance & Service manuals for the support system should be available for inclusion within the end user/building owners’ Operation & Maintenance manuals.

With all factors considered and selection made these alternative solutions are clearly the way forward for future projects that require mechanical and electrical building services supported on flat roofs. Speed, simplicity and robustness are key, and it is of no surprise we find ourselves working within an industry that chooses more often than not to use such systems over outdated traditional methods. After all time is money!

T

he installation at Coombe Fisheries, Barnstaple, one of the Southwest’s largest fish processing and exporting businesses doubles its capacity for processing, packing, freezing and storing.

Coombe Fisheries exports approximately 75% of its production and freezing and storing stock are an essential processing requirement.

Produce is predominantly shellfish, focusing on scallops, whelks and a range of cephalopods destined for consumption throughout Western Europe.

34_hubbard.indd 24

The high-performance refrigeration equipment is housed in a £4 million; 21,000 square foot purpose-built extension and serves newly installed facilities.

These include a holding freezer (-20°C), a 157m3 blast freezer (-25°C), two separate 262m3 blast freezers (-25°C), a Helix Spiral Freezer, Hybrid Tunnel & Contact Freezer and a HT Finishing Freezer (all -40°C).

KJ Refrigeration specialise in cooling for food processing and industrial applications. The two-year project was overseen by managing director Kevin Jones, who explains: “Our customer is one of the UK’s largest processors of seafood for wholesale exporting across Europe. The need is to freeze fresh products quickly while remaining environmentally sound. And, to have total control in matching the freezing duty to fluctuating volumes of product within the processing lines in an energyefficient manner was paramount.

“This was more than an installation of off-the-shelf packaged condensing units. The need for a collaborative approach with a single manufacturer with the capability to design the correct equipment and to create bespoke

The need to balance refrigeration reliability and running cost with an almost instantaneous response to cooling requirement and the maintenance of production quality are part of Hubbard’s approach to industrial process refrigeration and especially to the seafood sector. The company boasts a well-proven track record in sustainable refrigeration.

Hubbard was the first Carbon Trust ETL qualifying manufacturer of cellar cooling equipment in 2005 and most recently have been accredited with Triple ‘E’ approval for Irish businesses.

Working with KJ Refrigeration, Hubbard created a refrigeration plant schedule consisting of: • A twin installation of two Zanotti vertical discharge external housed packaged equipment to service the holding freezer, each unit providing cooling capacity of 28.5Kw • A single Zanotti vertical discharge pack to service the 1600m3 packing area • Two twin semi-hermetic internal screw compressor packs to service the two 262m3 blast freezers with a combined duty of 230Kw • Two twin semi hermetic screw compressor packs, externally housed with economisers and

n with KJ Refrigeration sub coolers, including receiver, control panel and weatherproof housing to service the Spiral Freezer with a duty of 199Kw and Contact Freezer (Crust freezer) with a duty of 90Kw • Inverter compressors were specified to ensure costefficiency through energy consumption and speed of response to production requirements Kevin Jones continues: “Coombe Fisheries and KJ Refrigeration have a long-standing relationship of over 30 years, and we are pleased to still be supplying a growing company in a globally competitive market place. Coombe Fisheries is supported by the EU, to develop a sustainable business model, to act as peer leaders and to reduce their carbon footprint through energy-efficiency.

“As refrigeration consumed almost 25% of the overall project

34_hubbard.indd 25

budget, it was a guiding principle that the chosen manufacturer could demonstrate knowledge of foodprocessing requirements”.

CUSTOM SOFTWARE “Hubbard’s expertise was immediately a valuable addition to the project team. The writing and debugging of bespoke plant management software ensured that Coombe Fisheries were involved in the fine-tuning of the refrigeration plant and equipment. A generic software package could only deliver average performance rather than a Coombe Fisheries specific solution.”

James Spear, managing director Coombe Fisheries adds: “This is a project that we started late in 2011 and completed at the end of 2014.

The development will give us the added capacity to build our export and domestic markets. Taking fish from the open market, processing, freezing and delivering across Europe.

“Having a reliable and trusted supplier like KJ Refrigeration who in turn have an excellent partnering relationship with Hubbard Products, an international manufacturer themselves, encourages us to believe we have achieved an industry leading processing plant.

That can only be good for Coombe Fisheries, the South West and for the UK as a whole.”

R32 and R1234yf/ze

Require New Equipment Scott Davies from JAVAC reports on the new equipment available on the market to support R32 and R1234yf/ze.

R32 IS FAST BECOMING A HOT TOPIC! Various AC manufacturers are now in the process of introducing split AC systems with R32 refrigerant.

R32 is already heavily used in Air conditioning equipment, as it makes up 50% of R410A. It’s a single component refrigerant so will not separate and it has a global warming potential (GWP) of 675.

It’s more energy efficient and will feature predominantly in smaller splits, 10kw and under. R32 has been classed as mildly flammable and is in the A2L classification.

So that’s the statistics over with what everyone really wants to know is where they stand with regards to recovering and detecting R32.

In the A2L category of mildly flammable means that engineers and companies will have to equip themselves with the correct tools for use on installations and service which do not have the potential to cause a spark!

The introduction of R32 will bring forward discussions within the industry regarding safe equipment to use and Javac UK is working hard to help ensure installers are ready.

Providing clear information on the new refrigerant recovery, vacuum and leak detection equipment on offer will ensure companies using R32 will be confident in their equipment. Javac UK will also offer

JAVAC.indd 26

“Engineers and companies will have to equip themselves with the correct tools for use on installations and service ” full training on the equipment and is also available to offer advice to wholesalers and end-users to help them make informed choices when selecting the correct recovery equipment and leak detectors when required.

HFOs such as R1234yf or R1234ze are also classed as mildly flammable in the A2L category.

They have very low GWP and are replacements for R134a. R1234yf is more commonly used in the automotive trade whereas R1234ze will be seen in the commercial industry. Their pressure and energy efficiency are however not suitable for replacing R410A in air conditioners and heat pumps.

Javac UK’s equipment will also be suitable for these refrigerants.

SUITABLE EQUIPMENT TO USE

XTR_Altima A2L

Recovery of this refrigerant will have to be carried out with a unit which is completely spark proof and has a potential to spark rating of zero. Javac UK has introduced the ALTIMA-A2L spark proof recovery unit. This is also the case when it comes to detection of the refrigerant were a leak to occur.

When detecting a leak only an ATEX approved leak detector will be suitable as anything not ATEX approved will have the potential to cause a spark.

ATEX is the name commonly given to the legal requirements for controlling explosive atmospheres and the sustainability of equipment and protective systems used in them.

Foreseeing this Javac has introduced the Gas-Mate ATEX approved leak detector.

Finally a suitable vacuum pump will also have to be used. Although the majority of the time there will

be no refrigerant present when performing an evacuation there is always potential that a small amount of refrigerant molecules could be dormant in the system which, when under vacuum, will be released. Alternatively, mildly flammable refrigerant could be present in the atmosphere.

For this circumstance Javac UK have the Bulldog A2L spark proof vacuum pump available.

Gas Mate Leak Detector

ALTIMA A2L SPARK PROOF REFRIGERANT RECOVERY UNIT The revolutionary Javac ALTIMA A2L has the fastest recovery rate in the industry due to its 240v V-Twin compressor design and is fully spark proof.

The recovery rates are as follows, Liquid-216kg/hr, Vapour-30kg/hr and push pull at 660kg/hr.

Along with R32 and R1234yf/ze the ALTIMA A2L is also suitable for all common refrigerants including R410a. The spark proof switches and circuit breaker are UL listed and the power supply lead is a hard wired with a length of 5m.

GAS MATE ATEX APPROVED HAND HELD LEAK DETECTOR The Javac Gas-mate is the UK’s only ATEX approved hand held leak detector with an accuracy of 5 PPM (methane) and is twice as sensitive as its nearest competitors.

The ATEX approval means that it is designed not to have the potential to cause a spark or means to ignite

JAVAC.indd 27

a combustible gas. Powered by two size D batteries the Gas-Mate comes from the same technology used in the ever popular Tek-Mate and D-Tek Select with incredible pinpoint accuracy. The Gas-mate will detect all hydrocarbons including R32, R1234yf/ze R600, R290 and also the leak detection product Trace-A-Gas.

BULLDOG 160 A2L SPARK PROOF VACUUM PUMP The Javac Bulldog 160 A2L is a 240v fully spark proof vacuum pump for use with all systems for evacuation which contained hydrocarbons.

This is a two stage oil sealed vacuum pump featuring a solenoid isolation valve to eliminate the chance of oil suck back. The dual oil demister is designed to eliminate all oil mist and smoke entering the atmosphere. This feature is unique to the Bulldog creating a clean atmosphere on large evacuations.

Using the correct equipment will ensure complete safety when using new mildly flammable A2L category refrigerants. There are also various training facilities up and down the country which now offer full compliance training on the refrigerants and equipment.

The importance of A-Gas Managing Director John Ormerod on why leak detection is playing a wider role in the lifecycle of refrigeration and air conditioning systems.

T

he F-Gas Regulations are placing an increased emphasis on leak reduction and having the right equipment to carry out this work has never been more important. The refrigerants we use are changing and in upgrading plant engineers and customers are left with two options – replace the entire system or retrofit it with an alternative refrigerant.

Replacement can be a timeconsuming and expensive route to take. To be fair, there are instances when this may be the only alternative but a retrofit is often a cost-effective and often more efficient way of dealing with problems within a refrigeration or air conditioning system.

Recently at A-Gas we have had first-hand experience of a successful in-house retrofitting project. At our offices in Portishead, near Bristol, an ancient 10 horsepower 28 kW Daikin VRF air conditioning system was running on R22 and needed an upgrade to comply with the ODS Regulations. If you follow social media you will know that R22 is still posing problems for many engineers and end-users even though it has been phased out.

28_agas.indd 28

The system at A-Gas, with ten separate air handling units containing 16.9 kilograms of refrigerant, was used to heat and cool the first floor office areas.

DECIDING TO RETROFIT In the first instance, we considered a replacement system but this was going to cost in the region of £30,000. We looked again at the project and saw that a retrofit offered an alternate way forward.

By using the Trace-A-Gas® leak detection system, a five per cent hydrogen and 95 per cent nitrogen mixture from A-Gas, we were able to get to the heart of the problem.

This enabled us to locate the leak and find evidence of former leaks.

We made the repairs, retested with Trace-A-Gas to make sure all was okay, evacuated the system and recharged it with R438A which has low Global Warming Potential (GWP) values. The system is now up and running as it should be and we have saved a lot of money into the bargain.

In this instance the use of leak detection also bought us time.

Because of where we are in the F-Gas legislation it gave us the opportunity to wait until the major manufacturers bring out R32 as a refrigerant for air conditioning

leak detection – rather than use R410A which we will ultimately have to replace anyway – so we can get to a point where we can replace it as we would like.

BETTER THAN SOAPY WATER In recent years there have been significant developments in leak detection. It’s hard to believe but some still think that spraying soapy water is all that is needed to detect any leak. In fact such an operation will only detect large leaks.

Advanced technology is already with us and Trace-A-Gas, a valuable tool for any retrofit when used with an electronic leak detector, can find leaks smaller than 5g per year.

28_agas.indd 29

Improved leak detection forms part of a rethink on the lifecycle performance of systems. The lifecycle of a system should now be the key factor for customers and engineers, and the industry is being forced to look at a more holistic approach to managing refrigerant use.

LEAKAGE CUTS As a result of this, sales of reclaimed refrigerant are on the up – and besides improved leak detection – there are better installation and work practices and equipment is more efficient in its use of energy. Enhanced equipment design and improved

training for contractors and skilled technicians is also contributing to this. In the UK, leakage in modern air conditioning systems has been cut drastically compared to the levels of 15 years ago and I expect this to continue.

ORIGINAL EQUIPMENT

<i Orm <i (mig

Manufacturers (OEMs) are also raising their game by producing better components which deliver more efficiencies. The industry is now more focused than ever on leak detection and this shows that we are beginning to get our act together with a more sustainable approach to working practices.

Refrigerant Phase Outs –

The Next Round - HFCs

by Jane Garthorpe from Cool Concerns

Here we go again.

BANS AND RESTRICTIONS

A

s an industry we are well used to phasing out widely used refrigerants and finding workable alternatives. We probably did not think so at the time, but we had plenty of notice to decide which the best alternatives were in both new and existing systems and to efficiently deploy them. For example we had to stop using R22 in new systems at the end of 1999, but had up to the start of this year to service them.

And here we go again! The revised EU Fluorinated Gas regulation introduces bans and quotas on HFCs as well as changes in supply and leak test regimes.

This will force industry to move away from high global warming potential (GWP) HFCs with a speed and uncertainty we have not seen in previous phase out scenarios.

30_cool concerns.indd 30

The service bans and restrictions on the use of some HFCs in new systems are quite clear.

From 2020 we will not be able to use HFCs with a GWP greater than 2500 to service systems over 40 tonnes CO2 equivalent. This equates, for example, to a system charged with 10.2 kg R404A. We will be able to use recycled R404A until 2030 – if we can get it.

There will soon be bans on using HFCs in many new systems, dependent on GWP, as show in the table below.

This is also quite clear, and in fact several of the systems in the table already predominantly use other refrigerants, such as domestic and commercial fridges and freezers where hydrocarbons are widely used.

THE QUOTA SYSTEM However, revised F Gas Regulation has introduced a quota system on

the supply of HFCs, and with it a huge degree of uncertainty. From this year there is a phase down in the amount of HFC that can be supplied, specified in CO2 equivalent and compared to the average supplied in 2009 to 2012.

The “average GWP” column is just that – it’s what the average GWP of HFCs sold in Europe would have to be if the quantity (weight) of HFC sold is to remain the same. So you can see that within a few years it is likely the suppliers will not be selling high GWP HFCs such as R404A (GWP = 3922) if they are to maintain sales volume. And a few years later lower GWP refrigerants such as R134a (GWP = 1430) are also less likely to be available.

The impact of the phase down may be greater than shown if, as expected, the requirement for refrigeration and air conditioning increases within Europe.

So the effect of the quota system

will be to phase out high and medium GWP refrigerants, but it will be market driven and not simple to predict in terms of timescale and availability.

In the UK we will be affected by HFC demand in the rest of Europe, making the situation even less predictable.

PHASE OUT AND ALTERNATIVES The impact of the quota system and the bans / restrictions means we are now urgently planning to replace R404A in both new and existing systems. Unlike previous phase outs we don’t know the exact timescale but we do have an increasing range of replacements available.

Some of the replacements, such as the R407 series (GWP approximately 2000), are actually better refrigerants, but their life is probably limited to a few years by the quota system. The longer term replacements are probably HFO blends, of which there is a proliferation as the chemical companies brew their own blends.

OTHER CHANGES The other revisions to the regulation seem minor in comparison with the effect of the quota, bans and restrictions, but should help reduce emissions. ₀ The supply of HFCs is now restricted to companies which are registered. This means they have to employ certificated engineers and have appropriate equipment;

30_cool concerns.indd 31

₀ Non hermetic systems which are pre charged with HFC (e.g. split AC) can only be installed by a registered company; ₀ The leak test regime is now based on the CO2 equivalent of the HFC charge in a system. The effect of this is more frequent leak testing of high GWP refrigerants (such as R404A), and less frequent testing for low GWP systems.

IN CONCLUSION The aim of the revised F Gas regulation is to reduce emissions of HFCs by 80% by 2030 compared to 2005 levels. It will certainly accelerate our move to alternative refrigerants (R744, HCs, HFOs).

But uncertainty in the availability of high GWP HFCs within a very short timescale is going to challenge the RAC industry.

For more information: Cool Concerns Ltd +44 (0)1684 290333 www.coolconcerns.co.uk

THE CONCEPT OF CO2 EQUIVALENT

The revised F Gas regulation uses CO2 equivalent to determine bans and leak test regimes.

The CO2 equivalent of a system is simply the GWP of the refrigerant multiplied by the weight (mass) of refrigerant in the system. Consequently the revised regulation has a greater impact on high GWP refrigerants.

Delifresh Gets a Quiet COMMERCIAL REFRIGERATION SOLUTION Five J & E Hall Fusion Commercial Condensing Units have been installed in Bradford at Delifresh, a specialist supplier of fresh produce and delicatessen products to the catering industry. The company works with hotels and restaurants throughout the north of England and is passionate about the quality of its products.

LONG-STANDING INSTALLER RELATIONS COOL, CREATIVE THINKING The installer of the new cooling equipment for the project was GRS Refrigeration of Leeds, who enjoy a long-standing business relationship with J & E Hall. This was recognised

by Delifresh, when it commissioned GRS to install the equipment at its new two-acre facility in Essex Street, just a mile from Bradford city centre.

The distributor was FSW. GRS Refrigeration, which will soon be celebrating 30 years in the cooling industry, is a business employing eight people, which carries out extensive work in the restaurant and catering industry. The new Delifresh premises, constructed from highly insulated panels, needed a complete install of equipment to cool five food-handling areas.

JE Hall.indd 32

With a total of more than 8500 cubic metres of cooled spaces, each having its own temperature requirements, the job presented some interesting challenges requiring equally creative engineering solutions.

Contracts Manager for GRS Refrigeration Andrew Pinder takes up the story: “Over the years we have found that there is usually a product from the extensive J & E Hall range that is right for the job. This is great for smaller companies such as ours because it

“ Price isn’t everything, of course.

The Delifresh unit in Bradford

allows the installation of top spec equipment at a price that is acceptable to the customer.

“The total project cost for the new site was in the region of £3 million but with reasonably modest cooling technology costs of around £150,000 we were able to compete on a level playingfield with the industry’s big names.

“Price isn’t everything, of course.

The equipment has to work and quite simply we don’t get any problems with J & E Hall thanks to the build quality.

Of course, with each installation being different to the last, there can always be questions on how to achieve a particular goal but there is little if anything that cannot be overcome with the great level of support they provide.”

THE HARDWARE SOLUTION The project for Delifresh called for a number of units to be installed to achieve the correct temperature requirements for cooled areas of differing sizes. Installed indoors were two 8.25 horsepower JEH2-

0825-L-3 Fusion units for the 10.4m x 6.3m -20°C freezer. Two ten horsepower JEH2-1000-M-3 Fusion units were installed outdoors for the 30.7m x 12.8m pre-pack area together with a single three horsepower JEHS-0300-M-3 Fusion unit for the 6.78m x 5m chilled store.

J & E Hall offers an extensive range of medium and low temperature reciprocating and scroll-housed commercial condensing units using R404a. Medium temperature scroll condensing units qualify for Enhanced Capital Allowance. This Government scheme allows tax relief for businesses investing in energy efficient projects.

The acoustically-lined Fusion range houses a reciprocating compressor which is fitted with a compressor jacket to further reduce noise.

Mr Pinder explained: “Although the area around the site in Bradford is not particularly residential, and there is a major road running alongside, we were conscious not to add significantly to the noise levels.

“The J & E Hall Fusion units we installed have inbuilt sound insulation for the cabinet and the compressors, so are particularly quiet, with the loudest of them being no more than 42 Db(A), even at full load.

“Another bonus of selecting this particular equipment for use in a busy location such as Bradford is the blue anti-corrosion coating seen on the condenser fins. It comes as standard on the Fusion units and gives increased resistance to any corrosive elements that may be present in the urban or industrial atmosphere. In the long term this will obviously extend the working life of the equipment but in normal use it also helps to improve condenser efficiency.”

The installation completed at the Delifresh site in Bradford demonstrates how, with the backing of high quality, reasonably priced equipment and support, a small company such as GRS Refrigeration can compete on equal terms with much larger organisations.

HOW EBM PAPST HELPS TO MAKE

BIG

ENERGY EFFICIENCIES WITH A NEW DIFFUSER

The fans manufacturer, ebm papst, won two awards at the National ACR Awards in January 2015, namely the ‘Refrigeration Product of the Year’ and the ‘Company Environmental Champion’.

W

ill Hawkins, editor of the ACR Journal, caught up with James Cooper, product manager at ebm papst, to learn more about the background to its new AxiTop Diffuser.

The first award you won in January was for the AxiTop Diffuser. To use the judges’ words, they said ‘it is a clever product and it makes a marked difference’. They were impressed.

Essentially, a diffuser is not anything new. We are attempting to improve the efficiency of already efficient EC products, to take efficiency another notch up.

Looking at the aerodynamics, one of the areas we wanted to focus on was the air leaving the impeller.

What you find is that as the air leaves the impeller there are losses

inherent in the design as the air comes away.

It is not just airflow. There is noise too. The diffuser converts some of the unused, or the useless dynamic power, into static, usable energy. Therefore, it regains some of the lost energy that you get from your electricity supply to the actual air power that is doing the work.

The diffuser does that by slowing down the velocity of the air leaving. We can do other things like straightening the air slightly, which improves the ‘throw’.

Overall system improvements can mean that you could improve an application perhaps because they were getting a bit of recirculation.

By throwing the air further you can get that improvement.

As a straight improvement on the impeller, we are seeing up to 27% improvement in energy saving for the same performance and the same duty.

However, actually we can improve an impeller’s capability by a further 9% running at full speed purely by adding the AxiTop on, and so converting some of that energy.

LESS NOISE, MORE PERFORMANCE There is another factor, which is the noise. With an impeller, like an axial fan in

a condenser or a chiller, there is a guard over the top. You need that there for protection. But, inherent in that design is the creation of some noise as the air is leaving the impeller, because it is quite close to impeller on the arm.

An added benefit of the AxiTop is that by moving the guard further away within the structure, the AxiTop allows you to improve the noise conditions as well. You get a significant noise reduction, up to 7.2 dBa. You can improve the way the air leaves the impeller to improve the flow. And, we can also reduce the noise. But, of course, by turning the fan speed down you get extra performance, which is also part of that noise reduction. It is partially the guard and partially the reduction in speed.

We have seen from trials and retrofits significant improvements on overall performance of a condenser or a piece of kit that is on a roof. That can range from anything from 15% to 51% depending upon the application and the speed of the fan because some of these installations are only doing part-load.

You wouldn’t expect to get full energy saving. But, we have seen 51% improvements in some cases purely because the installation was a bad installation. That has helped to stop or improve recirculation.

Have you been surprised by the applications where the AxiTop is being used? Or, is it where you predicted?

Pretty much going where we Continued on page 38

the manufacturers, not just the UK manufacturers, were using AxiTop and were using it maybe as an option, but it was there on their portfolio as this extra capability. And, they were selling it alongside the energy efficiency EC technology.

So, yes, it has been adopted and people are using it and seeing the benefits of it in varying degrees.

And even on retrofit upgrades installations it has been seen as a positive. There have big roll outs on various sites where they are adding this onto an existing EC impeller.

It is already a fairly new piece of kit but then they are looking to adopt even further benefits and savings.

expected. Typically, it is being used on the larger axial fans; we are looking at the 800 and 910 diameters. They are typically used on condensers, coolers and chillers, the refrigeration-type applications.

That’s where they are being used, but there is no reason why they can’t be used on any other type of industrial application where this a requirement to improve efficiency.

As long as it is on an impeller that is used in the way that the AxiTop needs to be used.

Sometimes products can take a while to be understood by customers and then be purchased.

Are your customers quickly adopting it?

They are. As you say, initially people want to see it in action, see what it can do, take samples and go through processes. But, I would say that most of the OEMs we supply to now have tested and are purchasing AxiTop for their equipment.

At ChillVenta at the end of last year, it was clear to see that a lot of

36_ebm.indd 38

Have you had to use any different type of materials to make it?

Or, does it purely come down to materials you have been using for a while, but using a different way to design it?

It’s the same materials we use on some of our impeller designs. We are always looking for new way of doing things, including moulding and shaping. It allows us to get the design and the shape more intricate than maybe metal one.

Our R&D team spends a lot of time designing new products on computers and can ‘iron out’ many of the ‘wrinkles’ in a product before making it. We also have our test labs where we can combine airflow and noise testing in one chamber. We listen to the tones and frequencies while it is being tested.

ADDITIVE MANUFACTURING 3D printing is a big thing with a lot of manufacturers now. We do a lot of prototyping on 3D printers. It is a quicker way to try an idea and try things out. We have 3D printing capabilities for all our works, plastics and designs.

It costs more to produce but you can quickly come up with something and test it. Even though it may be more fragile than

a finished tooled product, it still allows you to test it and prove the aerodynamics and acoustics before you really start putting the money into proper tooling.

With the efficiencies you can gain, I imagine you can get some pretty good paybacks with the AxiTop diffuser?

You can. From the efficiency point of view, you can help them do the necessary calculations with onsite measurements, depending on the installation. If you are looking at the total system saving, it is not necessarily the energy saved on the fan. That might be quite a small part of the overall system.

Think of chiller, for instance. If you have a free cooling coil on a chiller, which some of our OEMs have, and you can produce another 9% more airflow than you did previously for the same size of impeller, the same size of equipment, then it means that the system can run better.

You can ‘free cool’ a bit longer, be activated a degree or so earlier, in which case the compressors are not needed as much.

KNOCK-ON BENEFITS Therefore, the saving you get on those would be far outweigh the energy difference on the fan.

Although it is a significant saving on the fan, switching the compressor off is even better.

The knock-on system effect of the AxiTop Diffuser is important.

Although we can talk about the capabilities of what we can save on the fan, sometimes it is the system saving that is the bigger pull.

We might be talking a few kilowatts of savings with the fan. But, if you are switching compressors off, you might be saving huge amounts of energy.

Even if they are just switched off for an extra month per year. Or a few a year. It is significant over the course of a year on running a big chiller plant or several chillers.

Controlling condensation control w When insulation is correctly specified it can prevent condensation forming on refrigeration pipe work systems.

H

ere, Michaela Störkmann, Armacell Technical Department Manager EMEA (Europe, Middle East & Africa), discusses how a better understanding of condensation and advances in insulation performance are leading to improved specifications.

“The single greatest issue with refrigeration and air-conditioning pipe and ductwork is that surface condensation often occurs. This condensation not only accelerates the rate of pipe corrosion but can severely impact on the health of building occupants because it results

40_armacell.indd 40

in mould growth. Insulation used on refrigeration and air-conditioning pipe and ductwork must therefore prevent condensation if it is to extend the working life of pipework.

Aside from this, the role of the insulation is to maximise energy efficiency of the system.

Correct installation is important, too. If air, which always contains moisture in a gaseous state, can get to the coolant pipe, then condensation will still form. So, to avoid issues with condensation it is important that the right type of insulation is specified and that it is installed without air gaps.

HOT AND COLD Whilst hot installations (heating and hot-water pipes) are predominantly insulated to save energy, cold systems (such as the chilled-water pipes of air-conditioning systems or the suction lines of commercial freezers) need protection against condensation. On refrigeration systems, where the line temperature is lower than the ambient temperature, condensation is formed when water vapour comes into contact with the colder surfaces of the pipe and ductwork.

Eventually, this condensation can result in considerable damage. Apart from the expense of repair, there

may be further maintenance costs resulting from wet ceilings, spoilt goods or disruption to production process. In a food or drinks company, condensation raises serious concerns around product quality and contamination.

Moreover, the insulation effect of a material deteriorates greatly when it becomes damp, resulting in large increases in energy losses and corrosion of the equipment from moisture. For all these reasons, condensation control is therefore the primary aim of any lowtemperature insulation.

WHY CONDENSATION OCCURS Condensation occurs simply because there is only so much water vapour that air can absorb.

At 100% saturation, known as the ‘dew point’, the air is completely saturated causing moisture to be released in the form of droplets on cold surfaces.

At a given temperature and with a given relative humidity, the air contains a defined amount of water vapour. If air is cooled down, it reaches this 100% saturation at a specific temperature. If the air is cooled further, some of the water can no longer be held in the form of invisible water vapour and begins to form liquid droplets

40_armacell.indd 41

(dew point). The respective water vapour content of air at a given temperature can be calculated to work out the extent to which air of a certain relative humidity can cool without 100% saturation being exceeded and therefore condensation forming.

In order to prevent condensation, the surface temperature of the insulation must be as high as, or higher than the dew point temperature under defined ambient conditions.

There is a relatively straightforward way of calculating the insulation thickness required to ensure that the surface temperature of the insulation is at least as high as this dew point.

This involves knowing the line temperature and the ambient conditions (ambient temperature and relative humidity), defined as expected maximum values. In addition, it is necessary to determine the thermal conductivity of the insulation material, the object being insulated (pipe, duct and equipment) and the heat transfer coefficient of the surface of the insulation.

Although these variables should be calculated by the insulation specialist or installer, it is useful for the specifier to know how these individual factors influence the insulation choice and its maintenance.

INFLUENCING FACTORS There are a number of influencing factors when specifying insulation for refrigeration pipe and ductwork: Ambient conditions In order to determine the minimum thicknesses for low-temperature insulation, assumptions must be made about typical ambient conditions. A common mistake is to underestimate the impact of the relative humidity on the insulation thickness required to prevent condensation. For example, in some areas a 10 % increase in humidity can mean the insulation needs to be twice as thick.

Thermal conductivity of the insulation material The thermal conductivity value of materials typically used for technical insulation range from 0.030 to 0.060 W/(m²K). One parameter which influences the thermal conductivity is the mean temperature. In the case of elastomeric insulation materials, such as AF/Armaflex Class O, the thermal conductivity increases as the temperature rises.

This has a decisive influence on the insulation thickness, because the lower the thermal conductivity, the thinner the

insulation thickness. The thermal conductivity of materials should therefore be shown in combination with the mean temperature.

Heat transfer coefficient The heat transfer coefficient depends on the type of flowing medium, the flow speed, the character of the wall surface (rough or smooth, shiny or dark) and other parameters. The heat transfer coefficient usually consists of heat transfer through convection and heat transfer through radiation.

Convection makes a substantial contribution towards improving the heat transfer coefficient.

The faster the ambient air flows, the more heat is transported.

Therefore, in practice and when designing plant, it is essential to ensure that pipes and ducts have sufficient clearance to each other, walls and other installations. If this isn’t done it will prove difficult to install insulation materials correctly and there is also the danger of a build-up zone being created.

40_armacell.indd 42

Shape of the object Another crucial factor when calculating insulation thicknesses required to prevent condensation is whether the object to be insulated is a flat surface or cylindrical object (pipe). One of the consequences of this is that thinner insulation thicknesses are required on pipes compared to flat surfaces.

In the case of cylindrical objects the logarithmic ratio of the diameter of the insulated pipe to that of the un-insulated pipe must be included in the calculation.

To avoid having to carry out such complex calculations, we have developed our ArmWin Thermal Insulation Thickness Program, which provides all the typical calculations required for refrigeration, air-conditioning, heating and plumbing applications.

Summary Preventing condensation on the surface of pipework and equipment is a vital requirement in all refrigeration systems where the line temperature is lower than the ambient temperature.

To achieve this, low-temperature insulation must be correctly specified and installed, meaning it will perform over the long term, even under critical conditions. A key element of this is ensuring that the correct insulation thickness has been used. Another crucial factor is the quality of both the material and the installation, since this can have a dramatic effect on performance.

For cold applications, insulation requirements should be assessed, specified and installed by qualified contractors. If unsuitable materials, inadequate insulation thicknesses or poor installation practices are used the refrigeration system becomes vulnerable to condensation and corrosion.

Call Centre Makes Great Energy Savings with Panasonic HVAC System

P

anasonic was called upon by Woodhouse Environmental Services Ltd to provide equipment for call centre giant, WDS, to retrofit its busy offices with an energy-efficient Heating, Ventilating and Air Conditioning (HVAC) system. Working against strict time and space constraints, Panasonic’s VRF systems coupled with large ducted and wall mounted indoor units were specified for a quick, simple and energy efficient install.

WDS negotiated with the building owners, St Modwen Properties PLC, a multi-million pound property development and investment company, to redevelop one of three buildings at the Discovery Court Business Centre in Bournemouth.

OUT WITH THE OLD HVAC With the brief to remove and replace the old, existing system with a high-performance, easy-to-install HVAC system, the design and build contractor, Woodhouse Environmental Services Ltd, required a product that offered a large selection of different units, providing a maximum performance system to cater for this large building.

WDS Call Centre (a part of the Xerox group) provides customer service solutions to some of the world’s best known technology and communications brands including Tesco mobile, Google and many other blue-chip brands.

This complete system would need to cater for the high density office, providing exceptional heating and cooling efficiencies whilst maintaining close conditions, introducing continuous

fresh air and removing stale exhaust air, ensuring a comfortable work environment at ideal temperatures.

The install was to be undertaken whilst the tenants were still in residence.

This meant that it was imperative for staff disruption levels to be kept to an absolute minimum.

Woodhouse Environmental Services initiated a fast track install programme between June 2013 and October 2013, splitting the renovation into three phases to cover each ‘zone’ of the building, satisfying a tight budget, and remaining within the allocated time.

COMPLETE VRF CONTROL In the first phase, Panasonic’s integrated VRF and heat recovery ventilation systems were installed to replace the existing air cooled chilled water system operating on R22 along with a ducted fan coil system, which no longer provided the efficient and reliable service in this demanding application. Specifying Panasonic’s

As part of the second and third phases, Panasonic’s ducted indoor and wall mounted units were also incorporated in the building refurbishment. Not only were these systems integrated to provide fresh air input and stale air removal, but they also fitted the outlined noise criteria. Panasonic was able to supply all of this equipment on short notice so as not to delay the project.

As a result, Panasonic proved to provide the most energy efficient units on the market, suitable for this large-scale project. With approximately 250 members of staff based in each zone, the quick turn-around, replacing the old systems and fitting brand new Panasonic equipment, meant staff were able to move straight back into the refurbished offices immediately on completion.

RADICAL CHANGES BRING

SUCCESS A STEP CLOSER It is no great secret that challenges continue to mount for building owners and since the introduction of Part L and the updates that followed, the pace has quickened to introduce changes in the way that they operate their premises.

46_Mitsubishi.indd 46

O

ne of the main changes is that where once the focus would have been on the initial construction costs, the attention is now shifting to the running costs throughout the lifetime of the building.

Indeed, at the recent Building Controls Industry Association summit, the focus was heavily on these costs as the overwhelming bulk of where an owner’s money goes.

Of the three key stages in the lifecycle of a building: construction; operation and decommissioning, operation accounts for 80 per cent, with 10 per cent allocated to the build and 10 per cent to its decommissioning.

Of that 80 per cent operational cost, 80 per cent is swallowed up by the building services which include heating, ventilating and air conditioning.

It is no wonder, in today’s preference for sealed, air-tight glass and steel boxes with row upon row of computer terminals and lights blazing - all generating vast amounts of heat, that a building’s air conditioning plant has a major task to carry out if the occupants are to be kept comfortable.

This, inevitably, over the past few years, has caught the attention of Europe’s legislators in their drive to reduce energy consumption and the use of environmentally harmful

23/04/2015 09:08

47

VRF

acrjournal.uk

gases used in air conditioning equipment.

The new F-Gas regulations and the Energy Saving Opportunities Scheme have upped the ante further for building owners who must ensure their equipment, while continuing to keep employees cool and productivity up, is operating as efficiently and cost effectively as possible.

As a consequence, those at the front line of product development, the manufacturers, have turned their attention to materials and components in the search for better solutions delivering improved performance.

COMFORT AND CONTROL The new City Multi YLM VRF (Variable Refrigerant Flow) range of air conditioners from Mitsubishi Electric is the latest solution which meets this twin requirement to provide an efficient solution that guarantees comfort and control in a wide range of building types.

But this isnâ&#x20AC;&#x2122;t just another product which is slightly more efficient than the last one because at the core of the new range is a redesigned heat exchanger that represents a pivotal step change in providing more effective and efficient heat transfer.

Protected with a special zinc coating, the rangeâ&#x20AC;&#x2122;s world-first, flat tube aluminium micro-channel heat exchanger is ideal for the UKâ&#x20AC;&#x2122;s temperate climate, but this inaugural use of aluminium has called for a complete redesign of refrigerant distribution and heat exchange and as a result it offers up to 27 per cent annual energy savings when compared to the previous equivalent City Multi systems.

The flat tube aluminium heat exchanger in the VRF system not only delivers greater efficiency, it also means that the YLM

46_Mitsubishi.indd 47

delivers 26 per cent more contact with the refrigerant and 30 per cent more piping per area. At the same time, it reduces both weight and footprint and offers 10 per cent less system refrigerant volume than previous models allowing a more efficient and cost effective system where European Standard EN378 restrictions are in place (such as hotels).

SIZE IS EVERYTHING Perhaps one of the greatest obstacles to overcome is that of size, particularly in buildings where space is at a premium. But this is something which the range caters for with the smallest unit, the PUHY-EP200YLM-A model measuring just 740 x 920 x 1710mm in size, making it transportable in a standard building lift.

The design changes also include a new compressor which is optimised specifically to maximise efficiency during part load, therefore offering high seasonal efficiencies (see figure 1) and helping to reduce standby power consumption by 50 per cent by using an inductionheated compressor.

When it comes to achieving efficiency, building owners and managers are facing an uphill struggle and as legislation continues to change the battle will only become harder. But it is a battle which the whole industry is facing and manufacturers are meeting the challenge head on with new product development which paves the way for far greater efficiency in air conditioning systems.

The radical changes which have been incorporated into the City Multi YLM are certainly a step in the right direction and will bring building owners and managers closer to achieving success by delivering a far more flexible solution to the problem of providing a comfortable building in the most efficient way possible.

Fifty years of providing temporary HVAC solutions Where next for Andrews Sykes?

A

fter officially commemorating five decades of successful enterprise towards the end of last year, we take a brief look at the company’s early roots and steady growth and how this has promoted longevity.

In 1964, Andrews Industrial Equipment was founded predominantly as a heatingorientated business before becoming what is now known today as Andrews Sykes. Last year marked the company’s 50th anniversary, during which time it has become the country’s most prominent suppliers of temporary HVAC equipment.

The original commercial model involved importing portable heaters and steam cleaners from the United States, before redistributing them in England. However, it didn’t take long for the general focus to switch towards the concept of hire after a chance business deal between owner John Andrews and a Wolverhampton-based manufacturer.

By renting products to associates on a short-term basis, John realised that he could generate a regular income

48-andrew sykes.indd 48

without surrendering ownership of the units themselves. This was therefore a key moment in the company’s history and undoubtedly helped shape its overall structure going forward.

Rapid expansion led to additional outlets being opened in London, Glasgow and Nottingham by the end of the decade as the organisation branched out into other factions of climate control.

DEMAND BROADENS THE BUSINESS Despite flourishing during its preliminary years, there was an undeniable need for Andrews Industrial Equipment to broaden its range of products and services. With the demand for heating products

naturally subsiding during the warmer months, there was a pressing need to source an alternative during the summer period.

An expanding workforce and augmented nationwide presence meant the situation was becoming more urgent, but in 1969, a breakthrough came. John visited an international trade exhibition and whilst there, immediately recognised the potential of transportable air conditioning.

Within a few months he had set up a separate air conditioning division under the Andrews Industrial Equipment brand, and this was a huge step towards the company becoming the rounded business it is today.

17/04/2015 15:48

COMPANY PROFILE

Crucially, this development coincided with a sharp rise in offices and computer rooms being built across the country – providing countless hire opportunities with the contractors and facility managers involved. It was also around this time that Andrews probed the European market, opening a depot in Holland just seven years after being established.

NEW OWNERSHIP John Andrews oversaw the company’s continued growth throughout this period before eventually retiring in the late 1980s.

Acquired by Braithwaite Group a short time after, Andrews Industrial Equipment was then merged with Sykes Pumps – becoming what is still known today as Andrews Sykes Hire Ltd. Since the Millennium, a chiller division has also been successfully launched ensuring high capacity cooling requirements can be accommodated on any scale. At the same time, Andrews have gone to great lengths to increase their range of portable air conditioners to ensure customers from a full spectrum of industries are catered for.

Today, the company is accredited as being the UK’s foremost supplier of specialist hire equipment, with operations stretching as far afield as the Middle East. It’s primary aim remains to alleviate the dayto-day pressures experienced by customers by routinely implementing tailored solutions within a four hour time window.

Andrews pride themselves on having the ability to deliver and commission packages customised to specific requirements whilst adhering to whatever budget restrictions you may have in place. When breakdown occurs unexpectedly, they act quickly to

reduce the risk of output dwindling and costs rising.

This pledge is supported by a number of factors – including having engineers on standby 24 hours a day – but perhaps the most important is an unrivalled depth of resources suitable for assisting clients in every feasible scenario.

The Andrews cooling range is among the most comprehensive available, comprising of modest 2.6kW domestic air conditioners right through to 750kW fluid chillers designed for industrial applications and rigorous environments.

POPULAR PORTABLE COOLING In just fifty years, the company has progressed from a modest organisation operating locally to a multi-national firm with 75 depots across the world. The intermediate period has seen much growth not just geographically, but also in terms of the array of products now accessible in a revolutionised hire fleet.

The PAC 22 portable air conditioner, for example, is one of Andrews’ most frequently rented units due to its modern design and favourable specifications. Capable of cooling areas up to 990m³/h in size, this product is suitable for deployment in server rooms, large open offices, workshops and hotels.

At the top end of the range, their HPAC90 high performance unit is currently the largest self-contained air conditioner within the Andrews series. A nominal cooling duty of 90kW guarantees widespread cooling for considerably-sized indoor areas, requiring only a suitable power source to enable immediate functionality.

CHILLER SUPPLY As an extension to conventional air conditioning systems, the company also stocks a broad array of fluid

chillers, low temperature chillers and air handlers.

An all-encompassing product range ensures the demands of virtually any sector can be satisfied, with units commonly used in projects ranging from food storage to manufacturing processes.

When capacities exceeding 750kW are sought, two or more units can be coupled together as part of an adapted multi-megawatt arrangement. All equipment within the Andrews hire fleet has been designed in line with the latest technology whilst complying with current environmental legislation.

Energy reducing compressors help drive down the cost of running your system, guaranteeing maximum efficiency every single time.

FUTURE FORWARD Going forward, the organisation strives to maintain the steady levels of growth it has enjoyed over the last few years, with new innovations set for launch imminently. The Polar Wind Plus and PAC60 portable air conditioners have only recently been added to the Andrews range, and these will be joined by additional units in the upcoming months.

This continual investment in capital equipment is arguably the most fundamental influence in enabling Andrews to reaffirm their status as the UK’s leading climate control provider.

Details about your membership of industry associations and the benefits from being part of them

In the ninth of our Women in ACR series, we meet Julie Pringle, Technical Trainer at Mitsubishi Electric, who was highly commended in the 2014 ACR Trainee of the Year Awards.

Tell us about your educational background My background is not actually in refrigeration and air conditioning, it is in mechanical engineering. I served a mechanical engineering apprenticeship with Pilkington Glass in North Wales – I gained an ONC and HND in Mechanical Engineering at Bangor Technical College and for about twelve years after, was employed as a Design Engineer with various companies Years later, after finding myself in the RAC industry I gained a City and Guilds 7189 level 2 in Refrigeration, Air Conditioning and Heat Pump Systems.

Women in ACR.indd 50

At the back end of last year I was highly commended in the ACR Trainee of the Year Awards (after gaining my C&G 7189), and, part of the prize package was membership of the IOR. The amount and quality of information supplied is fantastic, keeping everyone at any level fully informed about the changes in the industry legislations and regulations and the potential of how it may impact us doing our jobs.

Who is your current employer?

I am employed by Mitsubishi Electric.

The head office is based in Hatfield in Hertfordshire, but as a Technical Trainer, my ‘office’ is the training centre part of, not only the head office, but the regional offices as well.

I predominantly spend most of my time in the Bristol and Birmingham regional offices, but occasionally will go the Hatfield or Manchester and very occasionally Livingstone, south of Edinburgh, where our Air Conditioning systems and Ecodan heat pumps are manufactured.

What attracted you to the industry?

It sounds funny but I was not really attracted to the industry, I literally fell into it. Back in 2000, I moved to Oxfordshire and, with my mechanical engineering background still active, I thought I would just take the first job that was offered to me until something more suitable came along and the rest they say is history.

The job I took was with a distributor of swimming pool equipment, sizing / selling air handing units / dehumidification units and air source heat pumps for domestic and commercial swimming pools – so my first introduction to heat pumps.

This start lead me into technical support / commissioning of ground and air source heat pumps for the domestic heating market and then four years ago I started working for Mitsubishi Electric.

What do you specialise in now?

Or, what type of projects do you work on?

I deliver design, installation & commissioning and service and fault finding training courses for

17/04/2015 09:50

WOMEN IN ACR

acrjournal.uk

Mitsubishi Electric’s domestic air source heat pumps (Ecodan) and also our air conditioning systems.

The people attending the training courses range from architects and specifiers to installation and maintenance engineers. For the Ecodan range of product this will range from private domestic to local authority and housing association

What do you know now about the industry which you wished you had known before?

Having always been in a male dominated industry I always new or thought, that I would have to work harder to be able to prove myself, and in my early days of apprenticeship that was true. I came into the refrigeration industry with the same open eyes and the same expectations, but I have not found that I am treated differently at all.

I wish that had always been the case; age and maturity may have something to do with it though!

What excites/interests you about the industry and your part in it now?

There are so many benefits to the end user for having renewable heat sources available to them. A lot of installers coming from a gas / oil background are not fully aware of the technology and what the benefits of having them installed are, so if I can give them the tools, in the form of training that enables them to go out and design the correct solution, install it according to industry requirements (Microgeneration Certification Scheme certifies microgeneration technologies used to produce electricity and heat from

renewable sources.) then I am doing my bit for this exciting and ever changing industry.

What are the benefits of being in your role (e.g. travelling, variety, monetary?)

What would you say to other women who are considering coming into the ACR industry?

No day is the same, no training session is the same. I am part of a brilliant company with a fantastic industry leading range of product to work with.

As my Mum would say ‘don’t be shy’, if you are then it is not the industry for you.

There are so many opportunities and paths that you can go down, it is not all brazing pipes and pressure testing (that is an important part though!!). If you are willing to learn and develop and apply your knowledge then it is a fantastic place to be.

Where do you see your career developing?

Without realising it, it is continually developing as Mitsubishi Electric brings new product into the market place.The implementation of changes through F Gas, means that the way we all work changes continually.

What are the challenges of this industry?

Julie was highly commended in the “Off the Tools” category of the 2014 ACR Trainee of the Year Awards Judges’ Comments “Julie shows determination and willingness to keep learning and developing knowledge and skills”

Employer’s comments “You can teach a person something, whatever that something maybe, but what you cannot teach them is attitude, passion and the drive to be as good as you possibly can at what you do” fortunately Julie has all of these qualities”

Trainer’s comments “For me Julie stands out as exceptional because she is someone who relishes the opportunity to learn the most she can herself so that she can multiply her knowledge by passing it on to others. In this she displays a very rare talent”

The main challenges I am faced with are to keep up to speed with the legislation and regulation of the renewables industry. Microgeneration Certification, Renewable Heat Incentive, Department of Energy and Climate Change etc. etc….. It is fair enough knowing about all these things but you have to apply them properly to each individual project and to be able to relay the information right first time.

May 2015

Out and About with Will Hawkins

VES

Will Hawkins meets the team at VES, the Chandlers Ford-based air handling unit manufacturer and service company.

I

met Tom Sands from VES, just before the business was about to go through a major development in how they operate and market themselves. It was a good opportunity to learn more about this growing business.

VES started in 1968 making air handling units in Andover, Hampshire. In 2002, the business moved to Chandlers Ford where it has two factories, as well as other offices around the country. With 250 employees and a turnover of £26 million, it is a notable company in the field of ventilation, heat recovery and air handling.

VES has been making, selling and installing its air handling unit solutions into some interesting places over its history, including the ‘Diamond Light Source’ project near Oxford, the Queen’s private chapel at Windsor and Lloyds Insurance in London.

MORE THAN JUST A MANUFACTURER That said, there is more to VES than its manufacturing business.

Half of their business comes from on-site assistance and service for their customers. For example, when a customer buys one of their air handling units, VES will help them install their new system when the flat packed

product arrives on-site. Much of their services business comes from working with retailers. In fact, around half of this business is from this market.

Refurbishment is another aspect of VES which, in an energy and cost efficiency obsessed world, appears to be a service that VES is wise to offer. Refurbished systems can costs between 25% and 50% less than brand new equivalents.

Interestingly, Tom added that they ensure a minimum 10% efficiency improvement on refurbished equipment. You can see why this service looks increasingly attractive for customers.

AHU overhaul is one part of that business. They also upgrade and refurbish fans, as well as incorporating new fans (mainly from Ziehl Abegg), for customers.

The company refurbishes their competitor’s equipment too. It is not uncommon for their engineers to be overhauling equipment made

by Trane, Carrier, Airedale, Flakt Woods or Lennox.

MADE TO MEASURE It is not all ‘off the shelf’ products and service business for the Hampshire Company. A standard product is not always appropriate, which is where the company’s bespoke solutions fit in.

Tom Sands (pictured above) gave me an example of where this service fits perfectly. A recent project was to provide bespoke air handling units for a Victorian hospital. Of course, the Victorians weren’t thinking about how they could incorporate a retrofitted, HTM 03 ventilation solutions into their designs. VES’s team designed and built a complete, tailored solution for the site.

Another one-off solution Tom mentioned, was to provide an air handling unit solution for the inflight refuelling aircraft for Airbus.

Out & About.indd 54

KEEP THE NOISE DOWN Noise is another problem which provides a good business opportunity for VES. Noisy AHU systems can be troublesome for people working close-by. Tom explained their acoustic design business and that many of their acoustic solutions end up in schools, hospitals and offices.

MAKING FRIENDS AND INFLUENCING THEM The main route to market for the business is by working with consultants and contractors.

But, VES also invest time in working with influencers.

For example, Tom explained about their work with the European Union on the future of swimming pools and the new disinfectant systems planned for the future.

The changes for the company are coming in the form some new machinery in their factory which will have an impact in two ways. Firstly, VES will expand its manufacturing capacity to be able to grow its business. The size of the new machinery means they will not have enough room in their factory.

The company is expanding its floor space too.

You can expect to see more information coming out of VES, if you are consultant or contractor too. The company recognises that it needs to differentiate itself by being more helpful, more knowledgeable and more approachable than its competitors. This will come in the form of more publications to help their customers effectively, such as technical guides.

VES has a solid history and an impressive range of skills and solutions. It is good to see British manufacturing businesses growing, adapting and thriving.

CONTRACTORS CORNER

The Ice Men are back with their latest AdvICE Men column, offering expert advice on a wide range of air conditioning queries in each issue of ACR Journal.

T

his month we’re looking at tooling issues and the latest product innovations that are launching in the not too distant future to make life that little bit easier for all you busy air conditioning engineers. Here are just some of the most common tooling issues that our technical team regularly come across when speaking to customers….

My current tube cutter isn’t cutting as effectively as I would like and I seem to be going through a high number of replacement blades. What type of cutter product would you recommend using to improve this?

This is a really common problem but it’s really easy to fix. When you’re choosing tube cutters, we would always recommend using a spring loaded model as they allow automatic, quick action tube cutting that will ultimately save you time on site whilst vastly improving the quality of the cut.

We would also recommend the use of a titanium blade; you will find that you will need to replace the blade much less frequently and it will cut through copper pipe much more efficiently, decreasing burrs significantly.

Contractors' corner.indd 55

I regularly use a multi head expander set on site but I can’t find a model that includes a ¼” head. Are there any models in the marketplace that you would recommend?

Unfortunately of late there haven’t been many expander set models in the UK market that include a ¼” head. However, TF Solutions are launching an expander set in time for summer 2015 that will include this size and offer a unique solution for engineers.

The inclusion of a ¼” head should prove to be really handy, avoiding the need to use hand swaging tools or fittings on site.

Look out for the launch of our new tooling products in the June issue and follow us on Twitter for further updates on our full range of air conditioning and refrigeration solutions.

Without using springs, is there a tool on the market that will do a return bend in tight spaces?

The short answer is yes. The new crossbow bender that is arriving at TF Solutions in May 2015 includes a reverse adaptor that will allow you to pull sets in pipework, for example in tight ceiling voids all done from below. This will make life much easier for engineers on site.

For any information on the tooling mentioned above or if you have any questions for the AdvICE Men, please email us at sales@tfsolutions.co.uk.

Mansfield Pollard Deliver Air Handling Units for ‘One Born Every Minute’ Hospital The Bradford AHU manufacturer show’s off its collaboration skills.

M

ansfield Pollard has been appointed by Whitehead Building Services (WBS) to design and install bespoke air handling units at Southmead Hospital as part of a £25M investment which supports the consolidation of pathology services with Public Health England.

The Bradford based manufacturer -which supplies energy efficient air management solutions to a global consumer base - has a reputation as a problem

solver within the industry thanks to its knowledge, experience and technical capabilities.

Mansfield Pollard supplied 15 air handling units each of which had to comply with stringent HTM03 hospital specifications. They were installed to serve the main office and pathology laboratories.

The team at Mansfield Pollard worked closely with WBS on the design of the system and developed a joint plan that took the project from the design stage through to installation and commissioning.

“based on their reputation and track record as an air management specialist we chose to work with Mansfield Pollard”

Simon Drinkwater, Senior Contracts Manager at Whitehead Building Services said: “We were delighted to be appointed as the mechanical and electrical contractor for the Southmead Hospital Pathology project. We then looked for organisations with whom we could partner and based on their reputation and track record as an air management specialist we chose to work with Mansfield Pollard who were one of our key partners on the projects.

“We were pleased with their flexible approach and with the way that they worked with us to develop an effective and efficient design.

We wouldn’t hesitate to collaborate with them on future projects.”

Joanna Robinson, Managing Director at Mansfield Pollard said: “This project is another example of how our collaborative approach together with the excellence of our technical solutions delivers real value for our customers.

“We look forward to further strengthening our relationship with WBS and to working together to deliver optimal solutions for their clients in the future.”

What's New May 2015.indd 60

BlueDiamond® is pleased to introduce the ArctikBlue®, a unique dairy tray for use in multideck and dairy cabinet condensate removal. Designed for where gravity drainage is not readily available, the ArctikBlue incorporates BlueDiamond’s ultra reliable MegaBlue® pump in a tough steel tray.

Using a thermistor sensor, not only are the problems of stuck float switches eliminated due to the slim line filter probe having no moving parts, the pump also only runs when condensate is present, making the ArctikBlue a welcome energy efficient product.

The ArctikBlue is able to remove up to 50 litres of water per hour at a maximum working head of 20 metres. Due to the use of the MegaBlue, the diary tray is able to run dry or self-prime, meaning it can be sited above any pipe work and away from hazardous areas.
