Plutus SX Refrigeration Oil is a naphthenic-based compressor oil with superior anti-oxidation properties. In comparison to paraffinic based lubricants which form larger amounts of hard carbons under heated environment, naphthenic-based lubricants forms smaller amounts of soft fluffy carbon. Besides its deposit control characteristics, it is also non-reactive with coolant compounds which typically found in refrigeration compressors. Plutus SX Refrigeration Oil is compounded from highly refined, low pour point oils with low wax forming tendencies and good water separation properties.It contain additional anti-oxidant which prolong the oil life. It is also thermally stable and has good chemical stability with most conventional refrigerant other than Hydrofluorocarbons (HFCs). Plutus SX Refrigeration Oil is specially formulated for reciprocating and rotary refrigeration compressors in air conditioning systems or refrigeration systems with chlorofluoro-carbons (CFCs) (eg. R12); ammonia (eg. R717); hydrochlorofluorocarbons (HCFCs) (eg. R22); carbon dioxide (CO2) (eg. R744); sulfur dioxide (SO2) or ethylene chloride (C2H4Cl2) as refrigerant. However, it is Not suitable for systems containing HFC refrigerants (eg. HFC 134a).
