2 stage

Hello everybody.I have a 2 stage semi hermetic bitzer 20hp and cutting from the thermistor.The compressor is away from the condeser fans.(so no air coooling).This is the reason of cutting or something else to looking for?its working on socking room in - 30C,the working presure is 1 bar in low and 18 bar in high.Thanks and sorry about my english.

The compressor suction cool or air cool.

Hi,

Check the liquid injection sight glass. If there is a shortage of refrigerant then, intermediate cooling is not done properly and compressor trips.
Cheers
