T/AS110/25 - HVPS D15 Cooling System

The quote/tender has ended, you cannot answer the invitation.

Goods Required: Design, Manufacture and installation of a new water chiller system for the D15 power supply cooling circuit. Purpose: The existing HV power supplies for MAST-U require an independent closed-circuit chiller system. A new chiller must be integrated with the pre-existing circuit and heat exchanger to provide sufficient cooling capacity. The chiller system must reject the heat outside of the building. The process fluid to be chilled is de-min water.
