[Clas12_rich] RICH Detector Cooling Circuit Pressure System Considerations

[George Jacobs]

Hi Saptarshi,

The high pressure section of the system is at 125 psi,  from the 
compressor output to the air tank. Pressure is reduced at the tank 
outlet to 55 psi or less by a pressure regulator to supply air to the 
detector air flow control valve. After that, it discharges to the the 
electronics enclosure inside the detector.

There are 3 relief valves in the system;
Relief valve #1 for the ASME air tank
Relief valve #2 and #3 for the detector air supply

I do not know who will do the procurement or when it is planned for. I 
have attached a spreadsheet with the list of known components for the 
cooling system.
