    thats only half the story. Don't forget the cryppump doesn't work indefinitely after the charcoal is full the cryo needs a regen cycle. Close the valve to the chamber heat the cryo and open an exhaust valve basically.

      Thanks for the additional info.

      What if you don’t open the exhaust valve during the regen cycle? What could happen?

      It depends on how long its closed, short time is no worry even a few minutes is fine. But if it is was never opened all the gas that was adsorbed will be released as the temperature rises, pressure will build. If its hydrogen for example it could explode. During the regen (that I am familiar with in the semiconductor industry) there is a purge cycle which includes closing exhaust port and filling with warm nitrogen, then open the exhaust and suck out the N2 and other stuff over and over until the temperature stops rising. There could be other procedures but this is how I know it to be. The cryos I use generally reach about 10-12 Kelvin after a regen, when the cryo warms to 18-21K its time for a regen. If it doesn't cool below 18K its time to replace or try to manually purge for a few hours. @@Macadamia923
