Synthetic ester refrigeration Oil
It has high stability with CFC refrigerant and good solubility in very low temperature especially for R22 and wide range of viscosity. The high viscosity rank selects enables it to have the very superior performance in the rotary system compressor. High viscosity can generate good seal ability between the rotors, and provide good lubrication between bearing and seals. It may provide the good solubility under the low temperature condition and guarantees the oil bath type evaporator good oil discharge situation as well as the good heat change efficiency. Besides, it possesses very low volatility and good oil gas separation property.
