Features:
Chemical Stability: To resist chemical reaction with the refrigerant or other material normally present in the system.
Thermal Stability: To eliminate excessive carbon deposits at compressor hot spots such as valves or discharge ports. Low Wax Content: To prevent separation of flocculant wax from the oil-refrigerant mixture at the low temperature points in the system.
Low Pour Point: To prevent separated oil from congealing in refrigerant lines.
Strength: To insure the good insulating properties. In hermetic units, the oil-refrigerant mixture serves as an insulator between the motor and the compressor body.
Proper Viscosity: Even when diluted with refrigerant so as to insure high film strength at elevated operating temperatures and while providing good fluidity under coldest operating
conditions.
No Contamination: To prevent scarring of bearing surfaces, plugging of lines or oil ports and general deterioration.
