EOI - Supply of Direct Drive Chiller

The Australian Nuclear Science and Technology Organisation is seeking expressions of interest for the supply of a direct drive chiller to replace Chiller 1 at the Australian Synchrotron facility in Melbourne. The existing unit has reached the end of its operational life after 22 years of service, resulting in a lack of available spare parts and a compromise in the facility's N+1 cooling redundancy. This replacement is critical to maintaining the continuous operation of the central refrigeration system, which supports essential HVAC and low-conductivity water cooling. The required system must be capable of maintaining chilled water temperatures with a supply of approximately 6 degrees Celsius and a return of 10 degrees Celsius. Heat rejection will be managed via a condenser water circuit with an entry temperature of 20 degrees Celsius and an exit temperature of 23 degrees Celsius. Interested parties must respond to solicitation PSC002905-01 by the deadline of November 9, 2026.
