SAM 4.0: Delivering energy efficiency at News Corp Australia

ng KAESER y, as well as t a number of

News Corp Australia (News) is Australia’s number one media company and part of the world’s largest global media and information service - News Corp. Over 11.2 million Australians consume news* and information from its suite of traditional print products alone each month. The print portfolio includes over 170 brands including a vast list of national, metropolitan, regional and community newspapers such as; The Australian, The Daily Telegraph, Herald Sun and The Courier-Mail to name only a few.

News has major print centres in Sydney, Melbourne, Brisbane and Adelaide. At every print centre, compressed air plays a key role as Rob Taylor, Engineering Projects Manager at News explains: ‘Compressed air is a fairly major portion of our production operation. From the paper reel handling machines, to the printing presses, and through to our distribution centres where the newspapers are collated and bundled ready for despatch - we rely on a dependable source of compressed air.’

Throughout the major print centres, News has opted over the years to include a number of KAESER compressors within their compressed air systems to assist them in meeting their demand for a reliable and efficient supply of compressed air.

Committed to environmental sustainability, in July 2007 News introduced an environment initiative called 1 Degree. From carbon reduction, to product stewardship, waste minimisation as well as recycling and water conservation, the philosophy of the 1 Degree initiative is to make small steps that add up to big change and lead to a sustainable future.

As part of this initiative the efficiency of the production operation was considered including assessing the compressed air systems.

KAESER report | 5

With a requirement to maintain compressed air pressure 24-7, or be it at a reduced capacity when the presses are not running, News therefore wanted to investigate how they could better control the compressed air system initially at the Sydney print centre - to meet this requirement as effortlessly and energy efficiently as possible.

Having a number of KAESER compressors in action across all of the major print centres, Taylor therefore called upon KAESER Compressors for a solution.

KAESER recommended installing a SIGMA AIR MANAGER 4.0 (SAM 4.0) compressed air management master system. A PC-based master compressed air management system, the SAM 4.0 allows the compressed air user to manage all of their compressed air production and treatment components from one single unit.

For optimum energy efficiency, the

SAM 4.0 utilises adaptive 3-Dadvanced Control to analyse the relationship between three factors; switching losses (start/stop), control losses (idling and frequency conversion) and pressure flexibility (average increase above required pressure).

Based on this information and the specific pressure required by the user, the SAM 4.0 then predictively calculates the optimum achievable configuration and adjusts the connected components accordingly.

As a result, just the right amount of compressed air power is provided to suit the specific needs of the application at any given time, with maximum energy efficiency.

Continuous fine adjustment with a view to achieving optimum energy efficiency (energy management in accordance with ISO 50001) and the option of predictive, demand-oriented maintenance, also keep life cycle costs to an absolute minimum.

'The SAM 4.0 has also optimised our energy usage and we have seen this reflected in our associated electricity bills'

6 | KAESER report

Initially a SAM 4.0 was installed to energy efficiently manage the compressed air system at the Sydney print centre.

Taylor commented; ‘We have had an excellent experience with the SAM 4.0 at Sydney. It has made the operation of the compressed air system extremely easy, sequencing the compressors to most efficiently meet our compressed air demand at any given time.

The SAM 4.0 has also optimised our energy usage and we have seen this reflected in our associated electricity bills. We have found the SAM 4.0 to be so successful that we have since put them into our Melbourne and Adelaide print centres.’ Since the inception of News Corp Australia's successful 1 Degree program in FY2006, the company has achieved a total carbon footprint reduction of 40% to FY2017.

News has since continued to initiate ongoing environmental improvements in every aspect of the business. *Reference - CMV: August 2018

How to realise your compressed air energy savings potential

Unlocking

energy savings

Any facility that relies on compressed air as source of energy will know that compressed air is a significant consumer of electricity. Not great news when you consider the heightened electricity costs we have all been faced with in recent years. However, what many compressed air users do not realise is that their compressed air system may well be hiding an energy savings potential of 30 per cent or more. Uncovering and realising these savings would assist them in reducing their associated electricity bill and therefore their carbon footprint.

Unlocking your energy savings potential The key to unlocking hidden compressed air energy savings starts with a compressed air audit. By monitoring a compressed air system for a set period of time, such sophisticated computer aided audits like the Air Demand Analysis (ADA) from KAESER, are able to determine precisely how much power and energy is being consumed by an existing compressed air system configuration.

identifying, repairing and implementing an on-going leak detection management programme, significant improvements can be made.

Reducing artificial demand and eliminating inappropriate use of compressed air may be other simple recommendations made, that when actioned will contribute towards increased energy efficiency.

Where appropriate, this information can then be used to simulate alternative configurations for optimum energy efficiency. As an example, proprietary tools such as the KAESER Energy Saving System (KESS) enable efficiency comparisons and accurate predictions of the energy savings that other solutions could make.

Energy efficient compressed air technologies A compressed air audit may also identify that significant savings can be achieved by replacing ageing or inefficient equipment. If we look at just the compressor, energy savings of approximately 10 per cent can be achieved through the use of efficient airends, 1:1 direct drives and efficiency optimised IE3 and IE4 electric motors;

Where can energy savings be made?

A compressed air audit may reveal simple improvements that could improve efficiency such as fixing air leaks. It is estimated that compressed air leaks can squander up to 50 per cent of the compressed air produced by a typical compressed air system. However, by

The airend of a compressor is essential to its overall efficiency. The specific power requirement of a rotary screw compressor is a direct result of the relationship between flow rate and power consumption. It will only reach its optimum specific performance at a certain pressure and speed.

8 | KAESER report

Advanced compressor manufacturers are able to make low speed airends for every size range that work in their zone of optimal performance. They tend to be more efficient than compressors with higher speed airends or gearbox or belt transmission, and are able to deliver more compressed air for the same drive power, generating considerable savings.

The drive motor also plays a part in a compressors overall efficiency. Direct coupled 1:1 drives offer the best efficiency with no loss in transmission efficiency and no maintenance requirements.

Belt drives do require some maintenance but offer advantages such as flexibility in pressure selection. Automatic belt tensioning devices further ensure transmission efficiency whilst protecting bearings from excess stress.

The efficiency of the drive motor should not be overlooked either. The efficiency classes according to the International Efficiency (IE) Code for low-voltage AC motors, describe the efficiency of motors in converting electrical to mechanical energy.

The standard defines the minimum requirements on the energy efficiency of asynchronous motors. In addition to the classes IE1 to IE3, the most efficient class of the standard is IE4 (‘Super premium efficiency’) which is – at this point in time – not yet legally binding.

In addition to the high degree of efficiency and lower energy consumption, the other benefits of optimised compressor drives are low operating temperatures and therefore a longer life.

As an example, compare the energy costs of a 15 kW base load compressor where one has an IE1 motor and the other an IE3 motor.

The performance efficiency of the compressor with the IE1 motor would be around 87 per cent, with a power loss of around 1.95 kW. Whereas the compressor with the IE3 motor would have a performance efficiency of around 92 per cent and only a 1.5 kW power loss.

The energy savings of opting for the compressor with an IE3 motor would therefore be 937 W. Based on the compressor running 8.760 h per year and a 0.15 $/kWh this would equate to $1,231.00 of energy cost savings per annum.

Taking control of energy efficiency Load optimisation and pressure reduction can also generate around 15 per cent energy savings. This could be achieved by introducing a master controller which manages all of the compressors and the associated ancillary equipment within a compressed air system. At its basic level, a master controller switches each of the compressor units in the system on and off as required to most efficiently match the compressed air supply to the demand.

Advanced master controllers such as the SIGMA AIR MANAGER 4.0 from KAESER, can deliver an advanced energy management solution.

By managing multiple compressors and selecting the right combination of compressors to meet the current demand requirements, the controller can reduce energy consumption thereby improving the performance and efficiency of a compressed air system.

It essentially achieves this by reducing compressor operating and idling times, reducing artificial demand and leaks and improving pressure performance.

It is therefore possible to improve the pressure stability and overall reliability of a compressed air system thereby keeping associated energy consumption to a minimum.

Achieving on-going efficiency Maintenance and service should also not be overlooked when it comes to operating an energy optimised compressed air system. It is important that a compressed air user follows the OEM’s maintenance schedule in order to ensure the system operates reliably at all times. When a compressed air system operates reliably it is able to operate efficiently, keeping associated energy costs down. Opting for genuine spare parts will also impact the reliability and therefore efficiency of a compressed air system.

Energy costs account for around three quarters of the overall lifetime costs of a compressor. As such a large consumer of electrical energy within a facility, operating an energy optimised compressed air system will therefore be an essential contributor in reducing a facilities overall carbon footprint.

Reliable & efficient compressed air supply for winery

A crushing

success

Award winning winemaker Teusner Wines recently invested in two KAESER SK 25 rotary screw compressors, which are responsible for delivering a reliable and energy efficient supply of compressed air to the pneumatic - grape crushing - presses at their new purpose built winery in the Barossa Valley, South Australia.

Based in one of Australia’s most wellknown wine producing regions, Teusner Wines has been making a variety of wines in the Barossa Valley for over 15 years. The heritage of their wines however far exceeds this, sourcing fruit from vineyards in the region that are up to 130 years old!

Everything is crushed one small picking bin at a time so that Teusner can keep a close eye on colour, flavor, aroma and structure, ensuring that the eminent flavours found in old

10 | KAESER report

Barossa vineyards take centre stage in the wines. Compressed air plays an important role in this process, powering up the pneumatics presses which are responsible in modern winemaking for pressing the grapes.

The pneumatic press is filled with grapes and once the door has been closed, compressed air is used to inflate a sealed bag within the press which effectively pushes the grapes against a large sieve that softly squeezes the remaining juice out.

KAESER report | 11

To keep up with growing demand, Teusner recently developed a much larger purpose built winery. This included sourcing two higher capacity pneumatic presses, which of course created a requirement for a larger capacity compressed air system.

With a typical harvest lasting only three months, the window to process the grapes is fairly short. It was therefore important to Teusner that they invested in a compressed air system that would be reliable and efficient, allowing them to maximise the harvest period.

Having received a recommendation on the KAESER compressor for this application, owner Kym Teusner, contacted the local authorised KAESER partner - Mobile Compressed Air (MCA) for a solution.

After reviewing Teusner’s requirements, MCA recommending and subsequently installed two KAESER SK 25 rotary screw compressors along with a 5,000 litre capacity air receiver.

Filling the presses with the grapes is a labour intensive process, so when a two-press system is in operation - as is the case at Teusner - they tend to run in separate sequences. This results in flatter air demand cycles. MCA was therefore able to recommend the installation of two 15 kW rotary screw compressors to meet the compressed air requirements rather than one larger unit,

12 | KAESER report

as the time in between presses gives the two compressors time to refresh the air receiver, bringing it back up to pressure between the crushing cycles.

For Teusner this meant cost savings, not only in terms of the initial capital investment cost, but also the longer term associated lifecycle costs of running the compressed air system.

The SK series from KAESER Compressors, would also provide the reliability and efficiency that Teusner required, not only delivering more compressed air for less power consumption, but also combining ease of use and maintenance with exceptional versatility in an environmentally responsible design.

At the heart of every SK series rotary screw compressor lies a premium quality screw compressor block featuring the KAESER SIGMA PROFILE rotors.

Superior efficiency is assured with these flow-optimised rotors that are able to achieve power savings of up to 15 per cent compared with conventional screw compressor block rotor profiles.

Needless to say, all KAESER SK series rotary screw compressors feature energy-saving, premium efficiency IE3 drive

motors.

In addition the SK series features KAESER’s innovative cooling system which uses a high efficiency dual flow fan and separate air flow channels for cooling of the motor, the fluid/ compressed air cooler and the control cabinet. This not only achieves optimum cooling performance, low compressed air discharge temperatures and minimal sound levels, but also promotes efficient air compression.

Finally, the internal SIGMA CONTROL 2 controller ensures efficient control and system monitoring, helping to push the boundaries of efficiency even further.

The compressed air system at Teusner Wines has now been up and running for over a year, as Kym said; ‘We have now had the KAESER compressed air system in play for one harvest and it worked perfectly. We have been really happy with the quality of the machines and the level of support we received from Mobile Compressed Air.’

'We have been really happy with the quality of the machines'

KAESER launch latest generation SM series

For maximum efficiency, the SM 13 and SM 16 compressor models are now equipped as standard with a superpremium efficiency IE4 motor.

this internal controller, compressor performance can be precisely adjusted to match respective compressed air consumption for optimum efficiency.

IE4 motors are the technology of tomorrow, with current regulation introduced in January 2015 only requiring the use of IE3 Class motors.

The control unit features an easy to read display allowing all information to be viewed at a glance.

For the end user this translates into best possible compressor performance, reduced energy costs and significantly enhanced compressed air production efficiency - today.

For even greater intake volume and efficiency, the latest generation of SM series rotary screw compressors are also equipped with the new SIGMA 06 screw compressor block, featuring even further refined SIGMA PROFILE rotors.

Together with the IE4 motor, KAESER has been able to reduce the energy requirement of these compressors by up to 13 per cent. All SM series compressors incorporate a SIGMA CONTROL 2. With

Where multiple compressors exist as part of a compressed air station, the SIGMA CONTROL 2 can easily be integrated with the master compressed air management controller from KAESER - the SIGMA AIR MANAGER 4.0 (SAM 4.0).

A key technology in the advanced world of Industrie 4.0, the SAM 4.0 seamlessly monitors and controls all components within a compressed air supply system for maximum cost savings, continuously fine-tuning system performance to ensure optimised energy efficiency.

These latest generation models remain maintenance friendly. All maintenance work can be carried out from one side of the unit. The housing cover is easily removed to allow excellent component accessibility.

In addition there is no need to remove the housing cover to inspect fluid levels or drive belt tension, as these can be checked via a convenient inspection window.

Sound levels as low as 62 dB(A) furthermore ensure whisper-quiet performance making them the ideal choice for point of use applications.

The SM series of rotary screw compressors from KAESER are available with drive powers of 5.5 to 9 kW, and produce flow rates from 0.59 to 1.62 m3/ min, designed for pressures 7.5 to 15 bar.

In addition, predictive maintenance is possible preventing unplanned downtime.

The importance of compressed air servicing

What really happens when servicing is neglected Have you ever considered what impact regular servicing, as well as the replacement consumables you choose have, on the on-going efficiency and reliability of your compressed air system?

which should be changed by a qualified Service Technician at prescribed maintenance visits which are key to the ongoing reliability and efficiency of your compressed air equipment.

Compressed air is often a critical source of power to many businesses.

If the compressed air system fails the consequences could be detrimental, from; long periods of downtime to loss of production and all of the associated costs this creates.

Maintaining the reliability of your compressed air system is therefore vital when it comes to ensuring it delivers compressed air when and where you need it.

Recommended maintenance schedules One of the most important requirements of an industrial compressed air supply system is maximum availability.

This is not only achieved by using the very best and most efficient components, but also by following the prescribed service and maintenance schedule.

The examples given here demonstrate what can go wrong when an OEM’s recommended maintenance schedule is not followed.

To ensure your compressed air equipment operates at the peak of its performance at all times and provides maximum production reliability, it is important to follow the manufacturer’s prescribed maintenance schedule.

There are a number of checks which should be completed, and consumables

real examples of what we have seen happen when recommended service schedules have been neglected...

blog This article has been taken from the KAESER Australia Blog kaeserknowhow.com.au

When it comes to maintaining a reliable and efficient compressed air system we often come back to the importance of following the OEMs (Original Equipment Manufacturers) recommended maintenance schedule and using genuine spare parts. Here we have a look at some real examples of what we have actually seen happen when servicing has been neglected...

Broken drive coupling What are the possible reasons this happened?

There may be a number of possible causes to why a drive coupling would break such as; too frequent stop/starts, too frequent load cycle changes, lack of maintenance and the screw compressor airend seizing.

What can happen as a result?

The drive coupling breaking caused the compressor to shutdown.

How could this have been avoided?

Drive couplings should be inspected at every service. They have a maximum life in term of operating hours and once this has been reached, they do need replacing.

Poor oil quality What are the possible reasons this happened?

There may be a number of possible causes as to why oil quality would be poor such as; a high volume of condensate in the oil, too cold running which means the condensation can’t evaporate, infrequent running cycles, extreme humidity or lack of routine servicing.

What can happen as a result?

Poor oil quality can lead to excessive oil carryover, filter blockages, internal corrosion as well as lack of lubrication. This would create wear and could ultimately cause rotating equipment - such as the screw compressor airend - to seize.

How could this have been avoided?

Aside from correct sizing of the compressor and correct control mode selection, poor oil quality could be avoided by following the recommended maintenance schedule and oil sampling.

Blocked filter/coolers/dirty environments What are the possible reasons this happened?

Blocked filters may occur for a number of reasons including; lack of regular routine servicing, extreme - dirty - environments as well as poor compressed air efficiency which leads to less compressed air being available.

What can happen as a result?

Overall blocked filters can lead to overheating. The effective oil life significantly reduces as well as downtime due to over-temperature shutdowns. Higher internal temperatures will also place additional stresses on internal components/seals etc.

How could this have been avoided?

If the environment is extremely dirty then finding a better location may help in avoiding blocked filters, however frequent servicing would also be crucial.

Texas BBQ Foods rubs - recently opt reliable supply of

Delivering a reliable and clean supply of compressed air

- a New Zealand producer of Texas-inspired smoked meats, cheeses, butter, sauces and ed for a compact and user-friendly KAESER AIRCENTER 6, to meet its requirement for a clean compressed air at its new state-of-the-art facility.

KAESER report | 17

Texas BBQ Foods is a family owned and operated company based in Inglewood in the Taranaki Region of New Zealand’s North Island. Here in a state-of-theart facility the team produce a range of Texas-inspired smoked beef brisket, pork belly, cheeses and butter along with rubs and sauces.

The family follows the traditional Texas

BBQ style of preparing meat which has its beginnings in the European meatsmoking traditions originally brought to Texas by German and Czech settlers in the mid-19th century.

Taking only the best NZ-grown beef and pork, a rub is first applied to the meat before it is smoked in one of the plants 4 big meat smokers using mesquite-chips for an authentic Texas BBQ flavour.

Once the meat is cooked it goes straight into a blast chiller, before it is sliced, vacuum packed and chilled, ready to be despatched and enjoyed.

The vacuum packing process is an important stage in ensuring the products retain their integrity, allowing consumers to enjoy the meats, cheeses and butters days or even weeks later.

In developing the manufacturing plant, it was clear that a reliable supply of compressed air would be critical to the operation, as Director of Texas BBQ Foods Ash Peters explains: ‘A critical factor in selecting a compressed air solution for us was to find one that would deliver a reliable supply of clean air. We also wanted it to be easy and low maintenance, quiet in operation and a nice tidy unit that would be simple to install.’

Compressed air would be required across the facility for various purposes including powering the thermoformer packing machine. This automated machine places the finished meats into trays before a vacuum seals the packets.

From the get go Texas BBQ Foods has wanted to use local suppliers wherever possible. With a good reputation and also local to the company, Texas BBQ Foods therefore contacted local authorised KAESER partner - Pace Power & Air for a solution.

After reviewing the requirements Pace Power & Air recommended and subsequently installed a KAESER AIRCENTER 6 that would operate with a food grade lubricant, along with two KAESER F6 filters; one KE and one KA.

18 | KAESER report

The AIRCENTER from KAESER Compressors presents the ideal solution where - like Texas BBQ Foods - a complete and compact turnkey system is required.

Within one space-saving compact package the AIRCENTER includes; a KAESER rotary screw compressor, an energy efficient refrigeration dryer and an air receiver.

The AIRCENTER has been designed to be user- and maintenance- friendly. It has excellent accessibility to all service points and in addition it includes a SIGMA CONTROL 2 controller for ease of system control and monitoring. With this internal controller, compressor performance can be precisely adjusted to match respective compressed air consumption for optimum efficiency.

At the heart of the AIRCENTER’s rotary screw compressor lies a premium quality screw compressor block featuring the KAESER SIGMA PROFILE rotors.

Superior efficiency is assured with these flow-optimised rotors that are able to achieve power savings of up to 15 per cent compared with conventional screw compressor block rotor profiles.

With sound levels as low as 62 dB(a) the AIRCENTER is also ideal for point of use applications.

To meet the air purity level required for food manufacture, two KAESER filters were also installed.

The KAESER filter range uses modern deep-pleated filter media to 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 compressed air system has now been in operation at Texas BBQ Foods for a couple of months and Peters concluded; ‘It’s doing exactly what it’s supposed to!

We are finding it to be reliable, nice and quiet in operation, user-friendly, requiring only minimal checks.’
