Gaseous Helium Recovery System three compressors with a maximum flow of 50m3/h each. This capacity corresponds to an evaporation of 200 l/h of liquid helium. Maximum pressure 200barIn the basement of the PH and BSP buildings a 15m3 buffer gas balloon is connected to the main recovery system installed at SPC.Each laboratory connected to the helium recovery system is equipped with a recovery manifold (main entry valve, non-return valve, pressure gauge, by-pass, gas counter, manual recovery valves three compressors with a maximum flow of 50m3/h each.
