Re: Petra water chiller
Basically it sounds as if one or both heat exchangers are leaking allowing water into the refrigerant circuit.
You need to prove the gas tightness of your refrigeration system.
Good Luck

Re: Petra water chiller
When you recommissioned the chiller after you replaced the compressors and evaporators, did you check and verify the function of all the safety devices? Glycol level of the chilled media, if running close to freezing?
The most likely scenario is that the first evaporator froze up and this caused it to leak, a new evaporator was then fitted but if the cause of the original freeze-up wasn't fixed the new evaporator suffered the same fate as the first one.
