RENISO KM 32, KS 46, KC 68 and KW 150 are recommended for use with ammonia (R717), with HCFC- (e.g. R22) and with hydrocarbon refrigerants (e.g. propane, propene, isobutane) in open, semihermetic and hermetic compressors. RENISO KES 100 is recommended for use in HCFC systems, especially when high evaporation and condensation temperatures can occur, as e.g. in bus and vehicle air conditioning systems.
