EOI - Supply of Direct Drive Chiller

Overview The Australian Nuclear Science and Technology Organisation (ANSTO) is seeking Expressions of Interest for the supply of a direct drive chiller to replace an existing chiller at the Australian Synchrotron (AS) facility. About The Australian Synchrotron is a world-class research facility operated by ANSTO at Clayton, Victoria. The facility operates continuously and relies on a central refrigeration system to provide chilled water for critical facility heat loads, including low-conductivity water (LCW) cooling and HVAC systems. Chiller 1 is one of four chillers serving the primary cooling circuit. It is approximately 22 years old, has accumulated significant run hours and has reached end of life, with spare parts no longer readily available. Purpose Replacement of Chiller 1 is required to restore reliable N+1 cooling redundancy and reduce the risk of loss of critical cooling capacity. Scope The scope includes: Supply of a direct drive chiller to replace the existing Chiller 1 at the Australian Synchrotron Provision of a chiller suitable for chilled water supply at approximately 6°C, with return water at approximately 10°C Provision of a chiller compatible with the condenser water circuit, which typically enters the chiller at approximately 20°C and leaves at approximately 23°C for heat rejection through the cooling towers Contractor Requirements Conditions for participation: refer to Part C of the EOI Instructions to Tenderers The proposed timeframe for this process is as follows: Issue of Expression of Interest: 19/10/2026 Closing Date for Clarifications: 02/11/2026 ANSTO Response to Clarifications: 13/11/2026 Closing date for Expression of Interest: 12pm 09/11/2026 Preferred Supplier/s selected for Request for Tender Phase: 20/11/26 Lodgement is via www.tenders.gov.au.
