POE (Polyol Ester) refrigeration oil is the dominant synthetic lubricant for modern refrigeration equipment. It enjoys good miscibility with HFC & HFO refrigerants including R32, R410A, R404A and R134a. With favorable low-temperature fluidity and high chemical stability, it is suitable for commercial refrigeration, central air conditioning, heat pumps and various new hermetic compressors. Its excellent oil return performance makes it ideal for most refrigerant retrofit projects.
