The difference between DRE and DRA series refrigeration oil
The new national standard GB/T 16630-2012 for refrigerating machine oil was implemented on January 1, 2013, replacing the previous GB/T 16630-1996.
The difference between mineral oil DRA and DRE under the new national standard:
|Refrigerant Gas||NH3 (ammonia)||HCFC (hydrochlorofluorocarbons)|
|Deeply refined mineral oil||Deeply refined mineral oil|
|Lubricant type||Synthetic hydrocarbon||Alkylbenzene, polyester oil, polyvinyl ether|
|typical application||Industrial and commercial refrigeration||Automotive air conditioning, domestic refrigeration, heat pump, commercial refrigeration including transport refrigeration|
u The refrigerant is partially compatible with the frozen oil, so that the two are mixed and have good fluidity at low temperatures.
u DRE is deeply hydrotreated and contains less wax than DRA
