Suniso refrigeration oils have the following characteristics which assure maximum trouble-free service life:
CHEMICAL STABILITY
To resist interaction with the refrigerant or metal parts in the system.
THERMAL STABILITY
To eliminate excessive carbon deposits at compressor hotspots such as valves or discharge ports.
LOW WAX CONTENT
To prevent separation of flocculent wax from the oil-refrigeration mixture at the low temperature points in
the system.
LOW POUR POINT
To prevent separated oil from congealing in refrigerant lines.
HIGH DIELECTRIC STRENGTH
To ensure good insulating properties. In hermetic units, the oil-refrigerant mixture serves as an insulator between the motor and the compressor body.
PROPER VISCOSITY
To ensure high film strength at elevated operating temperatures and good fluidity under the coldest operating
temperatures even when diluted with refrigerant.
NO CONTAMINATION
To prevent scarring of bearing surfaces, plugging of lines or oil ports and general deterioration.
