RFQ - Pumping Station with Integrated Leak Detection

The National Physical Laboratory [NPL] requirement is for a custom mobile pumping station/leak detector suitable for use with cryogenic systems. The system should comprise a turbo pump with backing/roughing pump and a leak detector which can be switched in/out of the circuit using electro-mechanical valves. It should be possible monitor and control the system (valves, pressures, status of the turbo pump etc) using an easy-to-use control panel. 1. The system should be able to leak test using He4 and preferably also...
