Tender: Replacement Direct Drive Chiller for Australian Synchrotron – Clayton VIC

About

The Australian Synchrotron (AS) is seeking a supplier for a direct drive chiller to replace Chiller 1 at its Clayton, Victoria research facility. The facility operates continuously and depends on a central refrigeration system to provide chilled water for critical heat loads, including low-conductivity water (LCW) cooling and HVAC. Chiller 1 is one of four chillers on the primary cooling circuit, is approximately 22 years old, has reached end of life and has limited spare parts availability; replacement is required to restore reliable N+1 cooling redundancy and reduce the risk of loss of critical cooling capacity. The existing system supplies chilled water at approximately 6°C with a return of approximately 10°C, and the condenser water circuit typically enters the chiller at about 20°C and leaves at about 23°C for heat rejection through the cooling towers.
