1. Excellent low temperature performance, strict pour point and U-tube fluidity can ensure that oil does not condense in cryogenic parts such as evaporator to meet the freeze-conversion requirements from high-temperature working area to low-temperature working area.
2. Excellent oxidation stability, the refrigerating oil is matched with appropriate antioxidant, and has better oxidation resistance, thus effectively extending the oil changing period of the refrigerating machine.
3. Appropriate refining depth, make sure that the oil will not accumulate carbon in the high temperature parts such as the valve and cause the blockage of the pipeline.
