Suniso POE oils

Lubrication is the separation of moving parts by a film of oil. The closer the parts are to each other—thatis, the tighter the fit—the more emphasis there must be on the role of lubrication. The refrigeration lubricant oils acts as an agent to lubricate internal parts, remove heat generated during compression, clean the system, act as a fluid seal and reduce energy requirements. Suniso presents POE oils suitable for wide ranges of compressors used in air conditioning and refrigeration processes.

• 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.
• High Dielectric Strength – To insure 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.
