9 MR Coolant Requirements
NOTICE
Equipment Failure. A continuous supply of facility liquid coolant to the Integrated
Cooling Cabinet (ICC) is required at all times for proper system operation. Failure
to provide liquid coolant with the requirements listed in this section may cause
equipment failure.
9.1 Integrated Cooling Cabinet (ICC) Coolant Requirements
1. The facility must provide liquid coolant to the Integrated Cooling Cabinet (ICC)
2. The facility must provide pipe/hose, filter, and connectors to the ICC
3. The facility must provide an uninterrupted supply of liquid coolant to the ICC at magnet
delivery
4. The ICC, ISC and CRY must be located on the same level.
5. The customer must provide and install an in-line flow meter on either the supply or return
facility coolant hose. The flow meter must be capable of visually displaying volumetric flow
between 10.5 and 26.4 gpm (40 and 100 L/min) and configured for the properties of the
cooling fluid in use
