Summit Matsu Chillers recently supplied a 36kW cooling system for research into the development of high technology equipment at the world class facilities at Australian Technology Park in Sydney. Working with other industry experts at Clean Rooms Australia, a cooling system was designed that provided optimal cooling for this significant R&D application.

Clean rooms is an Australian owned and run company which provides ‘turn-key’ clean room solutions for manufacturers of various high end technological products. A clean room is an environment that is absent of any static electricity and damaging dust particles. The dust is removed from the air by controlling air flow and by using various filtration systems. A clean room allows the production of technology equipment including circuit boards, wafer chips, flat screen television units and pharmaceutical grade drugs as well as providing a highly controlled environment for sensitive and rigorously quality controlled experiments and research and development projects.

Clean Rooms Australia worked with Bandwidth Foundry International, a photonics manufacturing and development company wholly owned and managed by the University of Sydney. Bandwidth Foundry International makes photomasks for semiconductors, MEMS, microfluidics, astrophysics and photonics industries as well as research and other applications using a state-of-the-art Heidelberg DWL200 laser writer.

Industrial process chillers from Summit Matsu Cooling systems are renowned for reliability, quality and durability. In this application these characteristics are critical. For without an effective cooling system, the research and development teams working in the clean room would have no means of regulating the air temperature for the manufacturing and testing environments. The cooling system in this clean room also functions as a means of cooling the sophisticated equipment used in their research and development cycles at the Australian Technology Park.

Father and Son duo Marshall and Benjamin Paul talk about the laboratory cooling system used by Clean Rooms Australia at Technology Park, for the university funded clean room project based in the Australian Technology Park in Redfern Sydney.

When asked about how significant a role the series 8 air-cooled – 36kw Summit Matsu cooling systems unit played in the operation of this clean room, Marshall Paul emphasised that: “The role of the cooling systems at the Technology Park Project was totally, absolutely and critically important to the operation of the clean room”. The company director went to further explain that: “by having a local supplier we were able to have a look at the cooling systems for the install, and have the manufacturer close by for servicing and support.” Summit Matsu Cooling systems yet again demonstrated the breadth of application for their Series 8 air-cooled cooling systems in providing controlled cooling for the highly sensitive clean room environment for Bandwidth Foundry at the Australian Technology Park in Sydney.

Summit Matsu Cooling systems have a long standing relationship with some of Australia’s top tier organisations. The high quality and reliability demanded by these companies and organisations is testament of the world class cooling systems designed, engineered and built by Summit Matsu. Kim Sweeny of Australian mining giant BHP Billiton, explains how even after 16 years of constant use, the cooling system units from Summit Matsu continue to perform exceptionally well on mine sites as part of BHP’s Nickel West project in Western Australia.

The cooling systems for BHP are being specifically used for water cooling in the safety shower systems in the processing plant of a Nickel mine site. As the surface water temperatures in the mine often reach in excess of 70 degrees Celsius and 52 degrees Celsius on the ground, using a cooling system to keep the right level of cooled water for use in safety showers is paramount on mine sites. Without a reliable cooling system in this case, maintaining the wellbeing and safety of the mine workers and other personnel would not be possible. The cooling systems’ optimal performance is critical for the safety showers, as not having it functioning means the staff are at risk of respiratory illness and other health problems.

Mr. Sweeny commented on the level of service provided to BHP by Summit Matsu Cooling systems in regards to the communication and maintenance of the cooling systems installed on the site, saying,
“We really try to support Australian manufacturers and the fact that we can get local support quickly for them with any problems or servicing is important for peace of mind”.

Several 40kWair cooled cooling systems were installed 16 years ago and although they are showing signs of age and weathering as well as mineral build up from the mine site, they still remain operational and perform reliably for water cooling for the safety showers.

With the regular and accessible servicing and maintenance provided by Summit Matsu, the cooling systems will continue to serve the purpose of helping to ensure the safety of workers on the Wiluna Nickel West project mines for years to come.

When it comes to manufacturing cooling systems, Summit Matsu are the experts and have a depth of knowledge that comes from over 50 years of experience in the industry. The cooling systems are built by the most experienced and qualified engineers who use high quality components which have been carefully selected from across the globe for use in cooling system manufacturing. Other industries that Summit Matsu serve include the food industry, HVAC, plastics, chemicals, mining, scientific, hospitals, pharmaceuticals, data centres packaging and many more.

Summit Matsu Chillers supplied Divex Asia Pacific Pty Ltd with the 30 kW cooling systems used in conjunction with their Sub Sea Rescue Equipment which provides chilled air to divers that have been rescued and remain in a hyperbaric rescue chamber located at the bottom of the ocean floor.

The arising need for a rescue action plan for working divers
A team of divers use Divex Asia Pacific equipment all over the world predominately doing work on oil rigs, fixing pylons and laying cables that lie on the ocean floor. Divers rely on equipment which connects to the ship that is controlled and monitored by workers aboard the ship for their continued survival for the duration that they’re under water working as well as for a destination to return to once they finish working.

In the scenario of an incident on the ship such as a fire or other problems, the divers would have no control or power to support themselves, or a destination to return to. Given the danger and risks involved in this line of work, preventative measures had to be taken to reduce these risks. To enhance work safety in this instance, a rescue action plan has been put in place in case any problems ever do arise with the ship that prevents the machinery on the ship being operational to support the divers. The cooling system is used as part of a rescue strategy to prevent the divers from being left permanently under pressure through ceased support from aboard the ship.

The rescue process & role of the cooling system
Aboard the diving ship is a support rescue boat and a hyperbaric rescue chamber. A hyperbaric chamber is a sealable diving chamber with a pressure vessel that has hatches which have enough space for divers to enter and exit, and an air compressor to raise the internal air pressure. Hyperbaric chambers enable divers to decompress, and if necessary quickly be brought up to the surface.

The hyperbaric rescue chamber provides a water tide environment in which the divers can remain until they are rescued. A container is kept on the rescue boat where the cooling system and other equipment is stored that will be required to support the divers who will be able to safely relocate to the hyperbaric rescue chamber. In the case of an incident, the nearest pressurised life boat is dropped into the ocean to assist the divers.

The rescue boat becomes the new location where the divers in the rescue hyperbaric chamber are controlled from through cables connected to pressure vessels. The divers remain in the hyperbaric rescue chamber until they are rescued and the cooling system ensures the chamber air temperature is comfortable for the divers in the mean time and prevents over heating. The function of the cooling system is to supply chilled air to prevent the chamber from rapidly over heating after deployment. The cooling system supplies chilled water to a heat exchanger which is converted to chilled air and pumped into the hyperbaric rescue chamber. The ambient air environment in the hyperbaric rescue chamber can reach anywhere between 40 to 50 degrees celsius and the cooling system brings this temperature right down to 25 degrees. This enables divers in the rescue hyperbaric chamber to remain in a comfortable environment, where they can breathe easily and avoid death resulted from overheating, lack of oxygen and dehydration.

Divex Asia Pacific headquarters in Scotland also has sales & support operations in Stirling & London in the UK, Germany, Dubai, South Africa and Australia. Divex Asia Pacific acquired the cooling system for saturation diving in this instance

The old way vs. the new way
Previously Divex Asia Pacific purchased cooling system from Italy, however there was a longer lead time, and if they had any issues with the cooling system it was “hard to deal with,” according to Allan Lewis – Production Manager at Divex Asia Pacific who looks after the cooling system. It was beneficial for Divex Asia Pacific to switch to a local Australian supplier such as Summit Matsu Chillers who in addition to being a local manufacturer had the most reliable industrial water chiller to offer. Further to this Summit Matsu Chillers were able to offer a much shorter lead time so that the Cooling system could be quickly manufactured for use in the hyperbaric rescue chamber.

The importance of cooling system reliability
For such an important application it was critical that Divex Asia Pacific have their manufacturer and service technicians close by for preventative maintenance purposes and also to address any technical questions or problems that may arise in order to consistently maintain the Cooling system so if any incident does occur with the ship, the hyperbaric rescue chamber and life boat action plan can smoothly be implemented to assist the divers.

The reliability of Summit Matsu Chillers in this case is emphasised by the nature of its application. If the Cooling system didn’t work in a situation when the rescue boat has been deployed then the divers would not survive a ship breakdown. A consequence of a rescue failure would result in the diving job being viewed as a higher risk and will reduce the amount of workers willing to work in this line of work which obtains such an important resource that is so necessary in the daily lives of individuals on a global basis. Therefore it is no exaggeration in saying the Cooling system are relied on when it comes to matters of life and death, and further to the daily lives in terms of oil availability and pricing. By aiding a rescue process a safe work environment is provided which encourages people to work in this industry.

Screenex Australia is a manufacturing company of polyurethane mining screens for the mining industry. Screenex injection moulded polyurethane screen panels are made from specially formulated Urethane and the modular design allows easy replacement of worn sections without having to replace entire screens. For mining customers this means less stoppage time for maintenance. Given how essential the quality of Screenex products is to mining companies, the quality of a locally supplied cooling system was paramount.

Screenex Australia purchased three cooling systems from Summit Matsu Chillers for use in both of their plants in Melbourne and in Perth. In Melbourne two 125 kW cooling systems with a tank and pump unit were manufactured and in Perth a 76 kW cooling systems was supplied by Summit Matsu Chillers.

In both Melbourne and in Perth the Cooling systems were used for the same applications. The Cooling systems are used to supply cooling to polyurethane horizontal plastic injection moulding machines. The Cooling systems supply chilled water to keep the dies, moulds and hydraulics cool via a heat exchanger. Here the Cooling system keeps the injection moulding at a constant temperature of 18 to 24 degrees celsius. The dies must be quickly cooled after the parts are moulded so they can be quickly injected. The Cooling systems’ role in this process enables Screenex to manufacture the polyurethane and create a reliable, long life, product of consistent high quality to supply their customers with.

As part of their medicine production process involving tube sealing for packaging and processing, Summit Matsu Chillers were required to manufacture a packaged cooling system. As part of the tube sealing process, the tube runs into a machine using a high temperature to mould the tube. A cooling system is then used to cool the tubes down to 10 degrees celsius prior to filling.

Pratash Samayak, Project Engineer for Probiotec talked of their previous packaging process before Summit Matsu Chillers had supplied them with the cooling system. They experienced a lot of down time because of their previous cooling system, from another supplier’s malfunction, having to send it off to be repaired and how it was causing a lot of problems with their packaging process.

Samayak contacted Summit Matsu Chillers to replace his existing Industrial chillers and said purchasing a Industrial chillers from Summit Matsu Chillers has “completely eliminated problems,” he went further to describe the benefit of having Summit Matsu Chillers on board, “it [the cooling system] saves a lot of time for us.”
