US Lube Vesta S Refrigeration Oil

US Lube Vesta S Refrigeration Oil is a naphthenic-based compressor oil with low carbon forming tendencies. In hot applications, it forms small amounts of soft fluffy carbon whereas paraffinic-based lubricants form larger amounts of harder carbon. In addition to its deposit control characteristics, it is also non-reactive with coolant compounds typically encountered in refrigeration compressors.

US Lube Vesta S Refrigeration Oil is compounded from highly refined, low pour point oils with good resistance to oxidation, low wax forming tendencies and good water separation properties. It is also thermally stable and has good chemical stability with most conventional refrigerants other than Hydrofluorocarbons (HFCs) are used.

US Lube Vesta S Refrigeration Oil is specially formulated for reciprocating and rotary refrigeration compressors in air conditioning systems or refrigeration systems with Chlorofluorocarbons (CFCs) (eg. R12); ammonia (eg. R717); hydrochlorofluorocarbons (HCFCs) (eg. R22); carbon dioxide (CO2) (eg. R744); sulfur dioxide (SO2) or ethylene chloride (C2H4CI2) as a refrigerant. Nevertheless, it was not suitable for systems containing HFC refrigerants (eg. HFC 134a).

Benefits

  • Excellent oxidation resistance reduces oil thickening, ensuring extended oil change intervals.
  • Non-reactive with conventional refrigerants.
  • Minimizes deposit formation.
  • Good lubrication properties and good low-temperature fluidity.
