Re: Cryo Refrigeration Help
I'm thinking there may be a restriction in the oil separator, possibly a plugged inlet screen if it has one... and if that restriction appeared recently that would explain why it worked better last year.
I'm guessing the pressure control is sensing the higher of the two pressures?
Is the RV on the condenser? If so, we could see a big improvement by moving the pressure sensing connection to the condenser out port.
But that does not resolve the restriction issue. You might want to contact the oil separator manufacturer to find out what their normal pressure drop should be.
