Suniso is a well-known brand of refrigeration oil. With its excellent lubrication performance, wide compatibility and excellent thermal stability, Suniso refrigeration oils are widely used in commercial refrigeration like supermarket freezers, convenience store refrigeration equipment, industrial refrigeration like food processing industry, cold chain logistics equipment, air-conditioning system like precision air-conditioning, household air-conditioning and automotive air conditioning.
Case Details
Suniso refrigeration oils have the following characteristics which assure maximum trouble-free service life:1.Chemical stability:To resist interaction with the refrigerant or metal parts in the system.
2.Thermal stability:To eliminate excessive carbon deposits at compressor hotspots such as valves or discharge ports.
3.Low wax content: To prevent separation of flocculent wax from the oil-refrigeration mixture at the low temperature points in the system.
4.Low pour point: To prevent separated oil from congealing in refrigerant lines.
5.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.
6.Proper viscosity: To ensure high film strength at elevated operating temperatures and good fluidity under the coldest operating temperatures even when diluted with refrigerant.
7.No contamination:To prevent scarring of bearing surfaces, plugging of lines or oil ports and general deterioration.
Example1Suniso GS range:Description SUNISO GS oils are premium quality hydrotreated oils designed for use as refrigeration compressor lubricant, with traditional
refrigerants. They are highly stable and are essentially wax free. They have long histories of satisfactory service in many types of equipment and are approved by most manufacturers for both factory fill and maintenance fill of their equipment.
Application SUNISO GS oils can be used in virtually any installation regardless of compressor or evaporator temperatures. They are ideally suited for low temperature systems where evaporator temperatures are below -18°C including residential and commercial refrigeration and air -conditioning systems. Particularly with HCFC and CFC r efrigerants such as R-22, R-502 and R-12.
Furthermore they perform excellently with natural refrigerants such as R-717, R600a and R-290.
Properties1.Chemical stability to extend service life, reducing maintenance costs.
2.Cleaner operation of the com pressor with fewer deposits and failures due to
valve sticking.
3.Excellent low temperature performance with no wax deposits to plug the
system.
Example2Suniso SL rangeDescription SUNISO SL grades are synthetic ester lubricants, formulated using select polyolester base stocks and additives providing outstanding lubricity, stability and corrosion protection. These lubricants are miscible in alternative refrigerants such as R-134a at extremely low temperatures.
Application SUNISO SL lubricants have been designed specifically for use in refrigeration and air conditioning systems charged with ozone friendly alternative refrigerants.
Properties 1.Miscible in alternative refrigerants such as R-134a, and most other chlorine free HFC refrigerants (such as R-404, R-407c, R-410a, R-507 and R509a/b, etc.), even at extremely low temperatures.
2.Provide outstanding lubricity, stability and corrosion protection.
