Refrigerator Oils

  • Atmos (N) products: Refrigerator oil (alkyl benzene synthetic) for refrigerating compressors using HCFC refrigerants.
  • REF oil NS products: Refrigerator oil (naphthene base) for refrigerating compressors using HCFC refrigerants.
  • Ze – GLES RB products: Refrigerator oil (polyester synthetic) for refrigerating compressors using HFC refrigerants (R410A, R407C, R134A, R404A, etc.)
