Product Introduction:
HDM-DRB refrigerating machine oil is carefully prepared by specially refined naphthenic base oil with low pour point and adding a variety of scientific lubricating oil additives. It has good lubricity, low temperature fluidity and excellent oxidation stability.
Application scope:
HDM-DRBrefrigeration oil is suitable for open or semi-closed refrigeration compressors or refrigeration units with chlorofluorcarbons (r12, r22), r502 and nh3 as refrigerants. Not applicable to refrigeration compressors with hfcs,r134a and r510 as refrigerants.
Performance characteristics:
Excellent oxidation stability is matched with an appropriate amount of antioxidant additives, which has better oxidation resistance, thus effectively prolonging cooling.
Oil change period of refrigerator;
Appropriate refining depth: ensure that oil products will not produce carbon deposition in high temperature parts such as valves and cause pipeline blockage;
Good detergency: the oil is transparent and pure, which can clean the working parts and effectively prevent impurity particles from rubbing against the bearing surface.
Good chemical stability, not easy to cause chemical reaction of refrigerant, leading to decomposition phenomenon.
