excellent Low temperature Performance: strict pour point and U-tube liquidity indicators to ensure that the oil will not be frozen in the low-temperature components such as evaporators and other condensation to meet the freezer from the high-temperature work area to free conversion of the work area needs; Oxidation stability: DRA series of refrigeration oil Matching the right amount of antioxidant additives, with better oxidation resistance, which effectively extend the oil refueling period; suitable refining depth: to ensure that the oil will not produce high temperature in the valve and other parts of the phenomenon, the occurrence of pipeline congestion ; Clean and good: transparent and pure oil, the working parts have a clean effect, can effectively prevent the occurrence of impurity particles friction bearing surface phenomenon. DRA / B series of refrigeration oil But also has good chemical stability: to ensure the stability of oil and freon refrigerant coexistence, to minimize the decomposition of refrigerant, compressed parts of the phenomenon of corrosion and other phenomena;

DRA / A series of refrigeration oil for ammonia (R717) refrigerant for the open ordinary refrigerator. DRA / B series of refrigeration oil for ammonia (R717), HCFCs (such as R12 for the refrigerant semi-closed Type ordinary refrigeration compressor or refrigeration unit.

DRA / A68, DRA / B46, DRA / B68, DRA / B100 are available separately, and other viscosity grades are available as needed.
