Refrigerant R-434A (RS-45)
RS-45 is an HFC (hydrofluorocarbon) refrigerant designed as a direct replacement for R-22, with zero ozone depletion potential. It offers highly effective retrofit performance while generating lower discharge temperatures than R-22, helping extend compressor life and improve system reliability.
Its low temperature glide makes RS-45 one of the most effective direct replacements for R-22 in flooded refrigeration systems.
