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.

RS-45 has established itself as one of the most effective alternatives for replacing R-22 in existing refrigeration systems, extending equipment service life without requiring complex modifications. Its operating characteristics support a smooth transition to refrigerants compatible with current environmental regulations while maintaining strong cooling performance. Lower discharge temperatures help reduce thermal stress on compressors, improving system reliability and reducing maintenance requirements. Thanks to its low temperature glide, RS-45 is particularly suitable for applications where operational stability and efficient performance in flooded systems are essential.
