Issue:
What is the acceptable moisture level in the oil and refrigerant?
Resolution:
Maximum moisture levels in the refrigerant circuit will need to be confirmed through both an oil sample and refrigerant sample. Values for chillers with Mineral Oil and R22 refrigerant will be different than those which contain POE and R134a. See below for specifications:
RTAA, RTHA, RTHB, RTWA:
- The moisture level in the refrigerant must be below 50 PPM.
- The moisture level in the oil must be below 50 PPM.
RTAC, RTHC, RTHD, RTWD:
The moisture level in the refrigerant must be below 50 PPM.
- The maximum moisture level in the oil must be below 300 PPM.
CGAM
- The maximum moisture level in the oil must be below 100 PPM
- Acid level less than 0.5 TAN
