Reliability and efficiency are just two reasons why DeLaval in Australia and New Zealand are choosing KAESER when it comes to delivering high quality and clean compressed air to its automated milking rotary’s. Most recently a KAESER compressed air system was selected to accompany the DeLaval AMRTM system installed at Bannister Downs Dairy Farm in Western Australia (pictured above).

Delivering clean compressed air to robotic milking systems

Almost 10 years ago, DeLaval - a worldwide leader in milking equipment for dairy farmers - created the world’s first automatic milking rotary (AMRTM). Developed to meet the requirements of large dairy farmers wanting an automated milking system, the AMRTM enables up to 1,600 fully automatic milkings per day.

To operate the AMRTM robots, the system relies on an efficient and clean supply of high quality compressed air, which in many cases is now supplied by a KAESER compressed air system.

Delivering compressed A consistent air is critical AMRTM.

clean and high quality air to the AMRTM and clean flow of compressed to the reliable operation of the

Once the cows are collected in a waiting area a crowd gate may be used to slowly and calmly move the cows into the AMRTM platform.

Preparation, milking and the exit stages of the milking process are then carried out by five robotic arms. Two arms manage preparation, two milking and one more manages the teat spraying at exit; In the preparation stage, a cup is attached to the teat where a unique combination of air and water clean, stimulate and strip the teat ready for milking. The next robotic arm then attaches the separate milking cups, which commences the milking process.

Once complete the first step in the exit process is delivered by the last of the five robotic arms. Finally before the cow exits the AMRTM each teat is sprayed individually using a separate line and nozzle to eliminate any risk of milk contamination.

In delivering a fully operational AMRTM system to a dairy farmer DeLaval will also supply it complete with a compressed air

system. Following on from a number of good experiences, DeLaval Australia and New Zealand now choose KAESER as its preferred supplier.

James Tomlin, the Technical Manager for Oceania at DeLaval explains: ‘Having had a number of good experiences using KAESER compressed air systems in Europe with the AMRTM, we are now also opting for KAESER with our installations in Australia and New Zealand. KAESER compressed air systems have proven to be reliable in operation, backed up with good sales and service support.’

Daubney – co-owners of Bannister Downs Dairy Farm.

Bannister Downs Dairy Farm prides itself on delivering premium quality farm fresh products - from milk, cream and flavoured milks.

Located in Northcliffe, which is in the lower South West region of Western Australia, they recently completed the build of their new Creamery. This greenfield site is where they now milk, process and dispatch all of their premium products daily to their customers.

In developing the Creamery every aspect was considered in the pursuit of excellence, and so it is no surprise then that this award winning facility is fitted out with technology that is leading global standards and is achieving the highest standard of product quality.

This included the decision to invest in a DeLaval AMRTM complete with a KAESER compressed air system for raw milk

collection.

The AMRTM at Bannister Downs Dairy Farm operates 24 hours a day and is responsible for milking part of the 2,000 Holstein Fresian dairy herd. Once the on farm milking process is complete, the milk is transported just 10 metres through stainless steel pipework into the processing facility, where it is processed and packaged ready for daily dispatch.

To deliver a reliable supply of clean, dry and high quality compressed air to the AMRTM, two KAESER SX 3 T series rotary screw compressors with integrated refrigeration dryers, complete with air treatment package and air receiver were installed.

The SX series from KAESER are small but mighty compressors that not only deliver more compressed air for less energy but also combine ease of use and maintenance;

At the heart of the SX 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 SX 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 Bannister Downs Dairy Farm this means more compressed air for less energy consumption.

The compact SX T models also include an integrated refrigeration dryer which is installed in a separate enclosure. An automatic dryer shutdown feature further aids energy-efficient performance.

In addition, a service-friendly design

ensures that all maintenance and service components are easily accessible. This significantly reduces the downtime associated with such tasks and helps to increase compressed air availability and minimise operating costs.

compressed air system is critical in the dairy being able to produce and deliver fresh products to its customers on a daily basis.

Finally, to meet the air purity level required for food manufacture, KAESER filters were also installed as part of the air treatment package.

Thanks to lowest-possible differential pressure, these filters efficiently ensure compressed air of all purity classes as per the ISO 8573-1 standard. Using modern deep-pleated filter media, they remove particles and aerosols, while a highly effective carbon fibre mat traps oil vapours. Together with innovative flow dynamics, they deliver exceptional filtration efficiency with minimal pressure loss.

‘The concept of robotic milking is still relatively new and the AMRTM at Bannister Downs is the first one DeLaval has built of its generation in Australia.

As fresh as it gets!

For Mat Daubney, having a reliable

He said;

We are relatively isolated – both being in Australia and our actual dairy location – which is even more reason why we need the AMRTM and the KAESER compressed air system to be reliable.’

12 months on from installation and Mat is pleased to report that the KAESER compressed air system has been running without incident; ‘and with a site that’s got quite a lot of new technology in it, that’s pretty good and something we’re really happy about’.

Are you safe guarding your compressed air quality?

Presenting the DHS 4.0 series air-main charging systems DHS 4.0 series electronic air-main charging systems from KAESER not only provide protection for the compressed air treatment components within a compressed air system, but also help ensure reliable compressed air quality.

This even applies following complete shutdown of a compressed air supply system, for example at weekends. In fact, it is here where the DHS 4.0 series truly come into their own.

A compressed air network is often depressurised following periods of downtime. As a result there is no flow resistance from the network pressure when the compressors are started. The compressed air treatment components in a compressed air supply system however, are designed to accommodate the flow rates and speeds that occur in the distribution network when the system is in load operation.

Therefore, without back-pressure present, there is the risk that filter and dryer components may become ‘overwhelmed’ by the sudden surge in airflow that occurs when the system re-starts. This can lead to filter element damage and to a raised pressure dew point in the refrigeration dryer. As a result, contaminants such as oil, particulate matter and humidity are introduced into the pipe distribution network and the process air.

DHS 4.0 series electronic air-main charging systems from KAESER eliminate these risks by guaranteeing necessary minimum pressure, which consequently ensures smooth network start-up and safe operation of the compressed air station. They also prove highly useful during system operation - and are

even essential for stations with multiple treatment lines - because they help assure consistently high compressed air quality.

If for example, a fault occurs with a dryer or a filter, the air-main charging system is able to shut down and isolate the affected treatment line. This not only assures consistent air quality, but also safeguards the pipe distribution network and the air consumers in the production facility.

Moreover, this protection saves money: it minimises the burden on compressed air treatment components, air receivers and pipe networks and also prevents surge loads caused by large changes in pressure from occurring. This consequently enables long service life, which in turn leads to considerably reduced costs.

Control and function capabilities have been extended with these next generation models: The air-main charging system can be easily adjusted to accommodate specific production periods and can be opened or closed, for example, via the controller’s timer function. The realtime display keeps the user informed of operational status at all times.

In addition to the stand-alone capabilities of the DHS 4.0, a SIGMA Network connection now means that like all other station components, it can be connected to the SIGMA AIR MANAGER 4.0 master controller for input and visualisation. All relevant information, such as pressure measurement values or status indicators, is shown in real-time and is formatted for cross-machine communication.

This allows the user to take full control of their compressed air system to assure maximum compressed air supply dependability.

Complete compressed air system control and connectivity

A ‘Tasti’ solution

New Zealand food manufacturer Tasti Foods recently invested in a complete KAESER compressed air system. This w the compressed air demands of its new wholefoods manufacturing hall, but also to reliably and efficiently deliver compr areas of the manufacturing facility. For maximum efficiency, complete control and connectivity of all components withi a SIGMA AIR MANAGER 4.0 master controller was installed.

From baked bars, nut bars, muesli/ granola and cereal style bars, to raw fruit and nut snack packs, dried fruits, nuts and baking products - on most supermarket shelves throughout New Zealand and Australia, you will find products manufactured by Tasti Foods.

Now in its third generation, Tasti Foods remains proudly New Zealand owned and operated. The company began life back in the 1930’s when two friends decided to start producing crystalised ginger. Fast forward over 80 years and now a workforce of over 250 produce a whole range of food products including co-manufacturing for a number of internationally recognised brands. They also supply nearly every supermarket chain in New Zealand and Australia with private label snack bars.

Operating an efficient manufacturing facility Tasti has always manufactured in New Zealand and has been in its current purpose built facility on the Te Atatu Peninsula for almost 50 years. In that time the factory has been extended and refitted several times as the company has grown. This modern facility is fully automated and designed to deliver the highest quality products, and Tasti continue to invest heavily in the required plant and facilities

10 | KAESER report

to ensure they can operate efficiently and to the highest quality standards.

Compressed air is mainly used for the automation of equipment in the manufacturing process. Some of the most sensitive pieces of equipment that compressed air powers at Tasti are the sophisticated and robotic packing machines. Here, compressed air powers cylinders that perform a number of critical tasks from; picking and making boxes, placing the products in the boxes, to then sealing the boxes up ready for dispatch. The equipment operates very quickly – it is able to pack over 800 products a minute – however, to do this it relies on a constant supply of high quality and dry compressed air.

The existing compressed air system was struggling to reliably and efficiently meet the compressed air requirements at Tasti.

Reoccurring failures in the compressed air line were creating downtime in some areas of production. At the same time as these issues were occurring, Tasti had begun planning the expansion of its manufacturing facility to include a new hall specifically to manufacture its burgeoning wholefoods ‘free from’ product range.

As Tasti started the planning process for the new build, elevated electricity bills had additionally led them to invite Energy NZ to conduct an audit on the existing manufacturing facility.

One area the audit highlighted was that cost savings could be made by investing in compressors that were connected through a controller to each other, and were well staged. As the manufacturing facility had developed over the years so had the compressed air system grown and changed. The existing compressors were therefore not linked together and so they had no control around staging.

There was also no ring main connecting all compressed air applications in the facility together to one compressed air source. All of these factors together led Matthew Barber, the Maintenance Engineering and Environmental Manager at Tasti,

was selected to not only meet ressed air to all other required in the compressed air station, to take the new build - which would require compressed air - as an opportunity to address the entire compressed air system for the manufacturing facility. As Barber explains: ‘We saw the expansion as the ideal opportunity to find one solution that would not only solve the issues we were having with the existing compressor system, but would also allow us to get the whole plant set up on a ring main from one central compressor room.

In addition we were keen to digitalise the compressed air system - linking all of the compressed air equipment together for optimum efficiency and system control.’

Not only do they deliver more compressed air for less energy, but they also combine ease of use and maintenance with exceptional versatility and environmentally responsible design.

set the highest standards for efficiency. In fact, they achieve power savings of up to 15 percent compared with conventional screw compressor block rotor profiles.

In addition maximum performance and energy efficiency are assured thanks to the inclusion of a super-premium efficiency IE4 motor.

Furthermore, the inclusion of the innovative Electronic Thermo Management (ETM) system dynamically regulates fluid temperature. This not only reliably prevents condensate formation and associated moisture damage but saves additional energy.

At the heart of every ASD compressor lies a premium quality screw compressor block featuring KAESER’s SIGMA PROFILE rotors. Flow-optimised for impressive performance, these advanced rotors help KAESER ASD compressors

For Tasti, incorporating the SIGMA AIR MANAGER 4.0 master controller was the final piece of the puzzle to ensure they had complete control of the entire compressed air system.

SIGMA AIR MANAGER 4.0 utilises adaptive 3-Dadvanced control to make air generation and treatment even more intelligent, reliable and efficient. By predictively calculating and comparing various operating scenarios, it selects the most efficient to suit Tasti’s specific needs at any one time. Compressor flow rate and energy consumption are therefore always optimally matched according to actual compressed air demand. In combination with the integrated multi-core processor industrial PC, the adaptive 3-Dadvanced Control is able to ensure optimised performance for Tasti at all times.

Delivering compressed air when and where required Now up and running the new KAESER compressed air system is delivering a reliable, efficient and high quality source of dry compressed air throughout the manufacturing facility - exactly where and when it is needed.

Barber concluded: ‘The new KAESER compressed air system has helped us solve a number of issues. The SAM 4.0 in particular has allowed us to develop a fully connected compressed air system, giving us a lot of control over for example our energy usage.’

Introducing the SECOTEC TG series refrigeration dryers

The energy-saving and compact giant KAESER has extended its range of energy-saving refrigeration dryers with the introduction of the SECOTEC TG series. Designed for large-scale industry they deliver stable pressure dew point performance with maximum dependability and energy efficiency all within a compact footprint.

Accommodating flow rates up to 98 m3/min, the new SECOTEC TG series of refrigeration dryers from KAESER ensure stable pressure dew point performance even under the toughest of operating conditions, with maximum reliability and minimal life-cycle costs, and all within a compact footprint. This is made possible thanks to a number of key design features: All SECOTEC TG series refrigeration dryers are equipped with the innovative SECOPACK LS heat exchanger system. Its latent heat thermal mass is composed of a phase change material.

Compressed air warms the material up to its melting point (thermal mass discharge), absorbing melt heat during the process. This is significantly more than the amount of heat that it can absorb based on its normal specific heat capacity (without the phase change properties). As a result, the latent heat thermal mass in the SECOTEC dryers has a dramatically higher thermal density than equivalent conventional systems.

It is therefore capable of delivering the same performance using 98 percent less thermal mass material.

Each dryer also comes equipped with the exceptionally user-friendly SIGMA CONTROL SMART electronic controller.

This provides intuitive operation and comprehensive information can be viewed at a glance from the colour display, such as; current operating data, active messages and a P&I diagram.

The high-performance thermal mass concept ensures stable pressure dew points and together with the networkcapable SIGMA C O N T R O L S M A R T

controller, it also guarantees long-lasting, energy-saving operation in all load phases.

The air-cooled SECOTEC TG refrigeration dryer models additionally feature a brand new ventilation system with unique exhaust air control that sets new standards for operational safety and cost efficiency.

Thanks to the use of a radial fan, the exhaust air ducting can be directly connected to the refrigeration dryer. The radial fans are powerful enough to blow the air out directly via the exhaust duct. Because they are frequency controlled they draw off only as much exhaust heat as is needed to maintain stable pressure dew point performance.

A previously needed auxiliary fan is no longer required. With the air hood gone exhaust air flow is reduced, which means that significantly smaller exhaust ducting can be used. Furthermore the independent exhaust air control allows the refrigeration dryer to be connected directly to the collecting ducts. Less installation height is therefore required which significantly simplifies system planning and assembly.

In combination with innovative exhaust air control, the air-cooled SECOTEC TG series with frequency controlled radial fan, ensures stable pressure dew point performance with maximum dependability and energy efficiency.

The SECOTEC TG series refrigeration dryers have been specifically designed for the use of R-513A refrigerant. Utilising this climate-friendly refrigerant will assist compressed air users in future-proofing

their system as Australia transitions to low-GWP refrigerants as part of the Australian HFC phase-down. It also ensures maximum efficiency and reliability – even at the highest temperatures.

With a compact footprint, the SECOTEC TG series have only a minimum need for space. In addition, they are easy to install with excellent accessibility for service. When it comes to service, the requirements are minimal - only the service unit in the standard ECO-DRAIN condensate drain needs replacing.

Unlike typical axial fans, the radial fan in the SECOTEC TG series models are designed to last for the unit’s entire service life.

Equipped as standard with a Modbus TCP module, the SECOTEC TG series of refrigeration dryers are Industrie 4.0 ready. They can be connected to the SIGMA AIR MANAGER (SAM 4.0) master controller, which enables comprehensive monitoring and management of the entire compressed air station. The result – maximum air availability for minimal cost.

Understanding your compressed air

Bill, a Maintenance Manager of a logistics centre, recentl compressed air system. He needed to double his facility’s ou more air compressors to meet the higher demand for compres questions we determined a new compressor might not be nece steps taken after Bill’s enquiry that assisted us in not only sa compressors, but also helped him lower his existing energy con Existing components;

Like Bill, if your output doubles, you may well think that your compressed air system is no longer able to meet the new demand for compressed air this now creates. The logical step most of us would therefore take is to call our compressed air provider and ask them to quote for additional compressed air equipment. However, as Bill found out, assuming you need additional compressed air equipment may not always be correct.

which compressors or consumers are already installed? Are you using a master controller? What is the state of the pipe network? Are you using heat recovery?

Installation location; what is the state of the supply air, air circulation and exhaust ducting? What are the space conditions like? What are the room ambients like? What is the state of the electrical supply?

The answer to all of these questions should be considered.

How well do you know your compressed air system?

The first step we recommend our customers take when they suspect they require additional compressed air equipment, is to undergo a hassle-free Air Demand Analysis (ADA).

Here measuring equipment is installed for a set period of time and continuously records the airflow by measuring the pressure differential. The information is stored in a data logger. Once retrieved, the latest technology allows precise, computeraided evaluations of the data, to generate precise consumption profiles of your system. In other words it determines what your actual air demand is throughout all operating sectors and at different loads.

The advantages of undergoing an Air Demand Analysis are threefold: one; it highlights weaknesses in your existing compressed air system, two; it identifies any poorly dimensioned installations, three; it lays the groundwork for the next step towards achieving an optimal compressed air station by calculating the energysaving potential.

An ADA includes the following 3 key steps; Here we create a precise requirement profile for each of your fields of application including gathering all the necessary production parameters and conditions such as:

Air quality; what air quality is required for each application? Do you require standard blowing air or clean room quality Class 0 air according to ISO 8573-1?

14 | KAESER report

The data retrieved from the air demand analysis can then be evaluated using computer-aided technology.

This not only generates a precise consumption profile of your existing compressed air system, but it can then be further utilised to compare several possible

Sophisticated evaluation systems, such as the KESS – KAESER Energy Saving System, also take into account the performance of the compressed air station during its overall service life. This means that any weak points in partial load operation can be detected in advance and remedied.

Furthermore energy efficiency is calculated by precisely comparing power consumption with the delivery of compressed air. The most economical solution is then selected from several possible concepts.

Outcomes for Bill Through following this approach above we were able to show Bill; • • •

he was using only half the total air available from his existing system, his peak production demand was under 30% of his available capacity, and leaks, artificial demand and other nonproductive factors were responsible for most of his air consumption.

Actual data produced by the ADA at Bill’s 9,290 square metre distribution centre

And, by then implementing the subsequent recommendations, Bill was able to save the cost of purchasing new compressors and lower his energy costs.

Adjacent you can see one of the graphs produced by the ADA showing actual data from Bill’s 9,290 square metre distribution centre.

Conclusion By fully understanding your sites requirements and current air usage profile, a tailored compressed air system can be designed – including correctly selecting and sizing all components - that meets your unique requirements for optimum efficiency and reliability, keeping your air costs to an absolute minimum.

Assisting truck workshop in reliably meeting its compressed air demand

Taking a

load off

New Zealand based Trucks & Trailers – a commercial truck dealership and automotive repair shop - recently invested in an all-in-one KAESER AIRCENTER 25 compressed air station to meet its requirements for an efficient and reliable supply of compressed air in its Auckland workshop.

From haulage, transportation and construction to transporting people - there are numerous commercial businesses and public services that require heavy-duty trucks, trailers, utes and vans. For over 30 years Trucks & Trailers has been meeting these requirements for its customers.

Trucks & Trailers is the authorised sales, service and parts dealership for Mercedes-Benz trucks, vans, x-class utes and Freightliner trucks in the North Island of New Zealand with locations in Auckland, Palmerston North and Wellington.

16 | KAESER report

When it comes to service and repair, Trucks & Trailers is the only Elite Support Certified Daimler dealership in New Zealand.

This certification advocates a culture of continuous improvement to ensure the dealership consistently perform at its best, as efficiently as possible, to deliver an exceptional customer experience and to ultimately maximise vehicle uptime.

To meet such high standards, Trucks & Trailers relies heavily not only on their highly qualified and trained technicians, but also on the tools and equipment in their workshops.

KAESER report | 17

Compressed air is an essential utility to the vehicle workshops required for many purposes such as running the air tools to pumping up tyres. An ageing compressed air system in the Auckland workshop recently led Kelly Henshaw, the Service Manager at Trucks & Trailers to source a replacement.

Henshaw contacted KAESER Compressors for a solution after receiving a recommendation from another company using a KAESER compressed air system.

Following a review of the workshop’s requirements, KAESER recommended replacing the ageing compressed air system with an all-in-one AIRCENTER SK 25 compressed air station.

The user-friendly AIRCENTER is a complete turnkey system which incorporates a KAESER rotary screw compressor, 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 Trucks & Trailers this would translate into more compressed air for less energy consumption.

Ideal at point of use, the sound adsorbing compressor enclosure additionally keep operational sound levels to a minimum ensuring a pleasant work environment.

A service-friendly design further ensures that all maintenance and service components are easily accessible. This significantly reduces the downtime associated with such tasks and helps to increase compressed air availability and minimise operating costs. Inspection glasses also allow for convenient inspection of fluid levels and drive belt tension whilst the unit is in operation.

Henshaw concluded: ‘The AIRCENTER was installed about a year ago and is proving to be reliable and efficient. We’ve also found the after sales support to be really good.

The compressed air system recently underwent a routine service with KAESER and the Service Technician that attended site was great, ensuring we were fully aware of what he had done as part of the service.’

‘The AIRCENTER is proving to be reliable and efficient. We’ve also found the after sales support to be really good.'
