SF-590 are fully synthetic lubricants developed specifically for Refrigeration compressors using HFC – 134a as Refrigerant. They are specially formulated Polyol Esters lubricants for severe service conditions that are beyond the capacities of conventional mineral oils, they improve the performance and efficiency of standard refrigeration
systems compared to conventional oils. Polyol Ester base lubricants have miscibility with HFC, refrigerants such as HFC – 134a, similar to that of mineral oils with CFC’s.
RECOMMENDED USAGE:
SF-590 lubricant is designed for refrigeration systems with very high reciprocating compressor temperatures. They are also suitable for very low evaporator temperatures and for screw compressor system using
refrigerants such as HFC – 134a.
PROVEN BENEFITS:
- Improved wear protection at high temperatures.
- No deposit formulation in low temperature systems.
- Fewer discharge valve deposit.
- Improved Compressor efficiency.
