Product performance
Excellent low temperature performance; Strict pour point and U-tube flow index can ensure that the oil will not condense at the low temperature parts of the refrigerator such as the evaporator, and meet the free conversion needs of the refrigerator from high temperature working area to low temperature working area; Good oxidation stability. DRA series freezer oil is matched with a proper amount of antioxidant additives, with better oxidation resistance, so as to effectively extend the oil change period of the freezer; Appropriate refining depth; Ensure that the oil will not produce carbon deposits in high temperature parts such as valves, and pipeline blockage occurs; Good purity; The oil is transparent and pure, has a cleaning effect on the working parts, and can effectively prevent the occurrence of impurity particles rubbing the bearing surface.
Scope of application
It is suitable for open-type general refrigerator with ammonia (R717) as refrigerant. DRA/B series refrigerating oil is suitable for semi-enclosed general refrigeration compressors or refrigeration units with ammonia (R717) and hydrochlorofluorocarbons (R12) as refrigerant.
