ENGIE Refrigeration has supplied what it claims is the world’s largest fleet of chillers using the sustainable refrigerant, R-1234ze, to ‘a major hospital’ in a suburb of Sydney, Australia.
Eight Quantum chillers, with a total refrigeration capacity of 10 megawatts, have been supplied. The company added: “In all chillers from ENGIE Refrigeration are now in operation in over 150 hospitals – from Germany to Iran and all the way to Australia. Over the past few months engineers have replaced all the existing systems at the Sydney hospital with eight new water-cooled Quantum chillers that use the eco-friendly refrigerant, R-1234ze. In combination with their energy-efficient operation, the chillers reduce the hospital’s ecological footprint related to its refrigeration supply to a minimum.”
The chillers were adapted to their specific environment, and could thus be ‘optimally integrated’ into the existing hydraulic system. Characterised by soft start-up, ‘extremely low noise’, and low- vibration operation, they feature ‘an impressively high power density – for maximum energy efficiency combined with a small footprint’.
Other features include
- ‘State-of-the-art’ electrical filter technology for operational reliability, and to safeguard highly sensitive hospital equipment against electrical faults.
- Multiple compressor configuration to ensure high availability.
- Oil-free and magnetic bearing compressor technology for ‘hardwearing operation’ – and in turn ‘significant savings in maintenance and operating costs’.
