Introduction

According to the Australian Industry Group, manufacturing in Australia is now growing at a record pace. Despite the disruptions that COVID-19 created in 2020, June marked the ninth consecutive month of recovery for the Australian PMIⓇ (Performance of Manufacturing Index). That’s good news. Nevertheless, we are all still faced with many challenges moving forward as a result of the existing pandemic. Here the implementation of advanced Industrie 4.0-ready technology is becoming ever more important to businesses that are taking this opportunity to streamline their processes to improve efficiency. When it comes to a compressed air system, in many cases efficiency - both in terms of energy efficiency and the efficiency of related processes - can be greatly improved with the implementation of high quality and advanced compressed air technology. In this edition of the KAESER report you will find a number of case studies which demonstrate this point. This includes our cover story with radiator specialist Trevor French Radiators. By identifying and meeting their precise compressed air requirements with highly efficient compressed air equipment, they have been able to slash their electricity bill in half and improve the efficiency of the processes in their workshop that rely on compressed air. You can read the full story on page 16.

A reliable and energy saving solution for laminate benchtops manufacturer

Master Benchtops – a specialist in the manufacture of laminated benchtops - has opted for a KAESER compressed air system featuring an ASD 60 SFC rotary screw compressor with SIGMA Frequency Control, to deliver a reliable and energy efficient supply of compressed air to its manufacturing facility. Master Benchtops specialises in the manufacture of laminated benchtops. Located in Smithfield it is one of the largest postformers in NSW, delivering its customers with the latest innovations in edge profiles. For over 30 years, the company has been supplying the Australian woodworking, joinery and kitchen industry with a range of laminates consisting of over 2,000 colours and patterns. Priding itself on providing high quality products and the best service available to its customers in a fast and efficient manner, Master Benchtops relies on not only a highly qualified and efficient team - but also high quality, efficient and reliable equipment. An essential utility Compressed air is an essential utility used throughout the manufacturing process at Master Benchtops. From powering the high tech CNC’s through to the beam saw, panel saws and bending machines - the list of applications that rely on a dependable and quality supply of compressed air at the facility is extensive.

Unfortunately the existing compressed air system at Master Benchtops was becoming less reliable with frequent breakdowns occurring. This prompted Managing Director Joe Chamoun to start investigating their compressed air supply further. As Chamoun explains: ‘We were not happy with the existing compressor. It was not performing to our requirements and we were experiencing more frequent breakdowns. When we started to look into this further we also found that the compressor was actually oversized for our requirements, and therefore it was also using more energy and therefore costing us more in electricity than it needed to. As a company we are very focused on becoming green in every way. To us this means making every part of our operation as energy efficient as possible, and therefore using less energy to manufacture our products. Frequent breakdowns, increased maintenance requirements and the growing unreliability of the existing KAESER report | 5

compressed air system - coupled with the fact that it was oversized and therefore not energy efficient - all led us to the conclusion that it was time to change to a better compressed air system. After researching a number of options, we contacted KAESER Compressors for a solution.’ Opting for a greener solution KAESER Compressors then evaluated Master Benchtops compressed air requirements and recommended installing an ASD 60 SFC rotary screw compressor with SIGMA Frequency Control (variable speed drive) complete with an air treatment package. The latest generation of ASD SFC series of SIGMA frequency controlled rotary screw compressors from KAESER deliver superior efficiency and save energy in multiple ways: They incorporate a completely new and innovative drive technology. Representing a significant technological milestone for KAESER, the new

synchronous reluctance motors - which were developed in close partnership with Siemens - boast significantly greater efficiency, thanks to considerably lower losses in the crucial partial-load range compared to asynchronous motors. The low moment of inertia of synchronous reluctance motors allows high cycle rates, thereby boosting machine and system productivity. Some of the technical advantages of the new motor design include near zero heat losses from the rotors, which keeps bearing temperatures noticeably lower. This in turn has a positive effect on service life, ease of maintenance, as well as drive availability. Moreover, KAESER’s use of variablespeed fans in compressed air production systems delivers additional energy savings. Controlled and monitored via the advanced industrial-PC-based SIGMA Control 2 compressor controller, compressed air delivery is matched with actual demand. Moreover it uses

dynamic control to keep costly idling time to an absolute minimum. Delivering consistent results The ASD 60 SFC series rotary screw compressor complete with an air treatment package, has been up and running at Master Benchtops now for some 6 months. Chamoun concluded: ‘We’re happy with the decision we made to invest in a KAESER compressed air system. There’s no doubt that opting for a KAESER was not the cheapest option on the market. However as they say you do get what you pay for, and for us that is proving to translate into consistency in terms of the supply of air, the quality of the air and the reliability of the air. The compressed air helping us meet our we’re already seeing energy efficiency in In the end it pays off machinery.’

Cost Iceberg

If you’re about to invest in a new compressor, what criteria will you use in making your selection? The purchase price? The installation price? Maintenance requirements and cost? Energy efficiency? Hopefully it is all of the above and then some. As an asset with a ‘life-span’, the true cost of your compressor will not start and end with just the initial purchase price but will transcend across its entire life cycle. Considering the life cycle cost (LCC) of a compressor is therefore key if you want to truly understand the full cost of ownership. In this blog post we discuss LCC as an approach to assessing the true and total cost of a compressor. Why the life cycle cost matters Like other machinery, a compressor will not last forever. It will have a lifespan. On average this is around 10 years however that will largely depend on a number of factors, not least the compressor technology, operating hours and operational environment.

Interestingly, the initial capital investment accounts for only a small fraction of the total costs at around 15% and even the maintenance costs are significantly low at just 8%. But as you can see, 69% of the cost of ownership of a medium sized compressor over the first 5 years goes to your power bill!!

Let’s take the example of an oilinjected rotary screw compressor with an expected 10-15 year life-span. It is useful to calculate the purchase costs over the average internal write off period of 5 years using the current interest rate. The diagram (centre) highlights how all the costs associated with operating this compressor breakdown over the first 5 years.

It begs the question: what should guide your purchasing decision? When you start to really see how the total cost of ownership breaks down into categories, and their overall weighting, you really start to understand why there are a number of other critical factors that you should consider when it comes to deciding which compressor to purchase, and not just the initial purchase price

itself. Again, at 69% of the total cost of ownership the energy efficiency of the compressor is pretty critical. Evaluating the total life cycle cost (LCC) of a compressor or the ‘Cost Iceberg’ What the example above demonstrates is that the initial investment cost is just the tip of the ‘cost’ iceberg when it comes to the total operational costs. There is a concept called the ‘Cost Iceberg’ which highlights that above the surface are your visible costs at around 15% e.g. your initial investment cost. But, under the surface are your indirect costs at approximately 85% - such as

69% ENERGY costs

maintenance and energy costs - and added together you get your true total cost of ownership (TCO). So, applied to our example above, what we can see then, is that the initial investment cost actually plays a subordinate role in the overall cost of compressed air production. Evaluating other key areas, such as the compressor’s energy efficiency and its maintenance requirements and costs, is essential if you want to truly understand the overall cost of operating the compressor. Any initial savings on investment cost for compressed air components, for example, may be greatly outweighed by higher energy costs. KAESER report | 9

An expedient and reliable compressor solution for Golden Bay Cement

reliability When an existing compressor in an established system becomes unreliable or fails, a swift solution is required. This was a key reason why leading cement manufacturer Golden Bay Cement, recently invested in a KAESER DSDX 305 series rotary screw compressor for its manufacturing plant in Whangarei, New Zealand.

From DIY projects to pavements, industrial buildings, retail stores and car parks, you will find Golden Bay Cement products in use - and being used for a wide range of applications throughout New Zealand. The longest standing cement manufacturer and supplier in New Zealand, Golden Bay Cement is also the country’s only fully integrated manufacturer of cement. This means that it quarries the raw materials used to make cement, right through to manufacturing the finished cement powder. Compressed air is an essential utility required throughout the cement manufacturing process, from facilitating the flow of materials from start to finish, to assisting with the actual manufacturing process itself. As such an integral component of the cement manufacturing process, compressed air reliability is essential. So when one of the base load compressors became unreliable and eventually failed, Aaron Polwart the Machinery Health Technician & Air Services Section Engineer at Golden Bay Cement needed a prompt solution. An expedient and reliable compressor solution Golden Bay Cement considered a number of options including repairing the existing compressor. In the end the most cost effective and expedient solution was to replace the compressor with a new one.

KAESER report | 11

Having already got two KAESER compressors onsite working reliably, KAESER was one of the suppliers contacted for a solution. With a suitably sized compressor in stock locally, a KAESER DSDX 305 series rotary screw compressor was therefore selected and installed at Golden Bay Cement. Designed for optimum efficiency, the DSDX series rotary screw compressors from KAESER provide energy savings as standard. In the latest generation models, the flow-optimised SIGMA Profile rotors have been further refined, providing the basis for exceptional energy efficiency.

GEMS regulations for 3 phase electric motors, and KAESER is currently the only compressed air systems provider to equip some of its compressors with IE4 drive motors.

are within easy reach and directly accessible from the front of the unit. This not only saves time and money, but also maximises compressed air system availability.

For the end user this translates into best possible compressor performance, reduced energy costs and significantly enhanced compressed air production efficiency. In addition efficiency is enhanced with KAESER’s 1:1 drive design. As the motor directly drives the airend, transmission losses associated with gear or V-belt driven systems are eliminated.

Last, but not least, the advanced and integrated SIGMA Control 2 compressor controller achieves additional energy savings and minimises cost-intensive idling periods through the use of a variety of specially developed control options.

'...we’re really happy with the performance and reliability of the KAESER DSDX...it's easy to use and it’s proving to require less maintenance.’ The use of high performance IE4 drive motors further maximises energy efficiency. These motors not only comply with - but - exceed prevailing Australian

An intelligent component layout also contributes to the energy efficiency of these compressors. For example, all service and maintenance points

Conclusion The DSDX 305 series rotary screw compressor has now been in operation at the plant for over 12 months, and forms part of the common ring main that supplies the whole plant with compressed air. Polwart concluded: ‘Thus far we’re really happy with the performance and reliability of the KAESER DSDX compressor. From an operational perspective it's easy to use and it’s already proving to require less maintenance.’

Introducing the latest generation of turnkey booster systems

Complete and compact KAESER has just announced the launch of its latest generation boosters that cover the 7.5 to 22 kW drive power range. The new CN C series booster models are energy efficient, complete and compact turnkey systems that are ideal wherever high pressure compressed air is required such as PET bottle production, process air applications and nitrogen generation. Powerful, compact and quiet, the CN C series of boosters from KAESER make no compromise when it comes to performance, dependability and energy efficiency. These innovative complete systems come into play when, for technical reasons, specific points in a production process require a pressure higher than the network pressure. Wholly redesigned with a clever new layout, the CN C series boosters quite literally have everything you need: The new CN C series boosters are completely unique. All applicationrelevant components are provided and configured ex-works for delivery of a complete turnkey system that is ready for immediate operation. With a footprint of only 1.9 m2 they are also compact keeping the space requirement to a minimum. And, encompassed within a sound enclosure keeps sound pressure levels down to as little as 71 dB(A). These next generation boosters are more energy efficient than ever before. A premium efficiency (IE3) drive motor is fitted as standard. This contributes to cost-effective energy usage, as does the generously dimensioned radial fan, which also services to ensure reliable temperature control.

taken in through openings in the righthand side of the enclosure. Once they have been used for cooling, the streams are combined, then blown up and out through the exhaust air outlet in the top of the enclosure. This clever design reliably prevents cool inlet air from mixing with warm exhaust air – for enhanced efficiency. As you would expect from a KAESER machine, the CN C series boosters are service friendly. All maintenancerelevant components, such as cylinders and venting valves, filters, condensate separators and oil drainage/filler

openings are easily accessible thanks to large maintenance doors. The removable panel on the cooler side allows simple belt changes and provides easy access to the cooler. For efficient control and monitoring of the compressor operation, the CN C series boosters come with an integrated SIGMA Control 2 controller. This automatically monitors all key values: initial and final pressure, block discharge temperature of the individual cylinders, drive motor winding temperature, oil pressure/ level and compressed air discharge temperature. A further key advantage of these new booster systems is that they are perfectly matched for seamless networking with their “suppliers” – making them fully compatible with Industrie 4.0 environments. This means that CN C series boosters are ideal for operations such as PET bottle production, process air applications, nitrogen generation and the provision of high pressure for testing facilities. The CN C series of boosters are available with drive powers of 7.5 to 22 kW, and produce flow rates from 0.8 to 8.0 m3/min. Initial pressure 3 to 13 bar, and final pressures 10 to 45 bar.

CN C series boosters feature separate cooling air flows for the compressor block, drive motor and control cabinet, which are KAESER report | 13

Meeting stringent air quality standards

Producing extremely

dry compressed air

Reliable and efficient compressed air treatment is essential in meeting the stringent air quality standards required in the manufacture of food and beverages. Here, KAESER discusses how its latest range of dry-running rotary screw compressors featuring the patented i.HOC rotating dryer - not only provide a dependable source of quality compressed air with pressure dew points as low as -30oC - but does so energy efficiently and all from within a space saving design.

There are some demanding applications in the food and beverage industry that require extremely dry compressed air. Generally speaking, the drier the air needs to be, the lower the pressure dew point required and, the lower the pressure dew point, the higher the level of complexity, space requirement and cost involved. But, for those applications needing to attain extremely dry compressed air to a negative pressure dew point of around -30oC, KAESER Compressors presents an integrated and intelligent solution that is energy efficient and space saving.

Integrated Heat of compression (i.HOC) dryers Where extremely dry and clean compressed air is required, KAESER’s dry-running rotary screw compressors featuring an “integrated Heat Of Compression dryer” (i.HOC dryer) may be just the solution. Here, the dryer is integrated within the dry-running compressor. In this dryer design the desiccant is contained in a drum through which the compressed air flows in an axial direction. Desiccant regeneration and compressed air drying take place continuously, within a single pressure receiver. The drying and regeneration sectors are separated, however, both structurally and in terms of process. Slight pressurisation of the drying sector ensures that once dried, the compressed air does not reabsorb moisture from the regeneration air flowing by, in the adjacent sector. Drying without additional energy consumption In i.HOC dryers, desiccant regeneration takes place continuously, using the heat that already exists in the hot compressed air. Following the final air compression stage in

14 | KAESER report

the compressor, the hot compressed air is not sent to the compressors second stage coolers and lost, but it is diverted directly to the drying sector of the integrated rotating dryer before it exits the compressor. The heat arising as a result of compression of the air is therefore also used for desiccant regeneration. This heat is freely available without cost, as no additional energy is required for the drying process. This translates into maximum efficiency and outstanding drying reliability. The perfect interplay between the compressor and dryer also avoids additional energy costs, which are unavoidably incurred in the case of conventional desiccant dryers which use additional, external energy for desiccant regeneration. Reliable pressure dew point Modern i.HOC units also guarantee reliable and stable maintenance of low pressure dew points to -20oC, and under special conditions even to -40oC. In integrated rotation dryers, the attainable pressure dew point is determined by the compressed air inlet temperature in the drying sector and the available regeneration potential, which depends on the mass flow of regeneration air and its temperature. The i.HOC dryer therefore uses the entire mass flow of hot compressed air available at the end of the second compression stage for regeneration purposes. This is why it is referred to as a “full stream” rotation dryer. The higher regeneration potential of full-stream rotation dryers is especially

Add arrows advantageous when it comes to high cooling medium temperatures at the regeneration air cooler, low compression ratios in the compressor and – in partialload operation – more consistent and significantly lower pressure dew points. Intelligent regeneration management The attainable pressure dew point will fluctuate with the temperature of the ambient air (insofar as it acts as a cooling medium) – and this effect is especially pronounced in air-cooled compressors with integrated rotation dryers. For instance, if temperatures temporarily peak around 40°C in the inlet area during summer months, it may be necessary to enhance the rotation dryer’s regeneration potential during this time, to avoid exceeding a required pressure dew point of -20°C. Here the discharge temperature of the i.HOC full-stream rotation dryer following the second stage (i.e. the regeneration air temperature) can be increased by a controlled bypass around the first compression stage cooler. The regeneration air temperature (and consequently, the regeneration potential) increases to ensure maintenance of the target pressure dew point. Using the bypass to increase the regeneration air temperature to meet process requirements makes sense – especially as the conventional technology available on the market for electrically heating the regeneration air consumes significantly more energy. Conclusion When it comes to meeting stringent air quality standards, reliably and energy efficiently, a dry-running compressor

with an integrated rotation dryer is an excellent choice for users with a certain usage profile: demanding requirements in terms of compressed air quality and pressure dew point consistency; relatively little installation space; and challenging environmental conditions.

How radiator specialist slashed its electricity bill in half with KAESER

Flushing out excess

energy cost

KAESER has assisted New Zealand based radiator specialist Trevor French Radiators in reducing its electricity costs by 50 percent. This has been achieved by replacing an ageing compressor with an energy efficient all-in-one compressed air station. From cars, trucks and vans to industrial earth-moving machinery and everything in between, Trevor French Radiators has been specialising in the repair and replacement of radiators now for over 30 years. Based in Auckland, New Zealand the company prides itself on delivering unbeatable quality service. From cleaning radiators with a bead blaster, to using gas torches for welding, and powering the paint guns in the paint spraying booth - compressed air is an essential utility used and relied upon every day in Trevor French Radiators’ workshop. Unfortunately the ageing compressor powering these tools was becoming more and more unreliable, and with the

compressor running continuously on load / off load without ever stopping, Trevor French Radiators was finding that the compressor would cut out most days when it reached a high temperature. Assuming that a service may resolve these issues, Graeme Tutt, the Director at Trevor French Radiators contacted the original supplier for a quote. However, due to its age the quote was extremely high and it looked like replacing the compressor with a new one would be more cost effective in the long run. Tutt contacted a number of local compressed air suppliers for a solution including KAESER Compressors. Quick to respond, and after visiting the workshop and assessing its compressed

'by far the most significant change has been to our electricity bill. This has halved since we installed the KAESER compressed air system!’ air requirements, KAESER recommended and subsequently installed an AIRCENTER SK 22 to replace the ageing compressor at Trevor French Radiators. Remaining proudly manufactured in Germany, the user-friendly AIRCENTER is a complete turnkey system which incorporates a KAESER rotary screw compressor - complete with the highly efficient SIGMA Profile screw compressor block - an energy efficient refrigeration dryer and an air receiver all in one space-saving compact package. At the heart of the SK series rotary screw compressor lies the premium quality SIGMA Profile screw compressor block. Operating at low speed, the KAESER screw compressor block is equipped with flow-optimised rotors for superior efficiency. Furthermore, all SK series rotary screw compressors feature energy-saving, premium efficiency IE3 drive motors, which comply with and exceed prevailing Australian GEMS regulations for 3 phase electric motors. For Trevor French Radiators this would translate into more compressed air for 18 | KAESER report

less energy consumption. As the new system at Trevor French Radiators would remain situated in the workshop itself where space is at a premium, the AIRCENTER was ideal with a total footprint of just one square metre. Another pleasing attribute of the AIRCENTER for Trevor French Radiators was its low sound pressure level. Thanks to its sound adsorbing compressor enclosure, operational sound levels are kept to a minimum. At just 66 dB(A) it would prove to be quiet in operation - something really important where a compressed air system is situated at point of use. The AIRCENTER was supplied complete with filtration. Previously the ageing system did not have a dryer or filtration. This meant that there was a lot of moisture present in the compressed air reticulation system - not ideal when compressed air is being used for applications such as blast and spray booths. The AIRCENTER with its integrated refrigeration dryer, alongside a filter system meant that high

Tutt commented: ‘The KAESER compressed air system has been up and running now for over 5 months. One of the first things we noticed is how quiet it is in operation - you can barely hear it! The only downside has been that now we can hear air leaks which we couldn’t before - but that’s not a bad thing because it highlighted something we weren’t really aware of before and we are now addressing this. By installing a compressed air system complete with a dryer, we have also noticed a big difference - especially with our bead blaster. With no moisture in the line, parts are being cleaned a lot easier and faster. But, by far the most significant change has been to our electricity bill. This has halved since we installed the KAESER compressed air system!’ Trevor French Radiators also chose to take out a service agreement with KAESER Compressors to ensure the compressed air system continues to operate at its optimum, efficiently and reliably into the future.
