PLUTO NA is premium quality refrigerator compressor oils, formulated from hydrotreated naphthenic mineral oils, high mobility, very low pour point, designed for refrigerator compressors: piston, crew, centrifugal with refrigerant: Ammoniac (NH3), propane, CFC, HCFC.


  • Excellent mobility characteristic al low negative temperate, fast heat transfer, oil circulation and lubricate is easy.
  • Good anti-rust, anti-corrosion, anti-wear and protect surface details absolutely.
  • High purity, flash point temperature and insulation, low evaporation to prevent oil leakage, safe operation.
  • Not chemical reaction with refrigerant, good thermal stability and resistance oxidation, help to operate works enduring.
