Fundamental question (air in the system)
Where are collect the air in the a NH3-Refrigeration-System

-45°C Booster and -20°C Compressor, Tc = 32° to 40°C
Collect the air for itself in the condenser or in the receiver tank, and why?
We have to same NH3-Refigeration plant on the world, only small differences in the thermo-siphon installation.
In one plant, we find the air in the receiver tank, drain out be gas purge.
In the other plant, we find the air in the condenser, here we can not drain out the air and we have trouble with oil temperatures is much to height.
Thank you !
