The refrigerant R508B gas is an azeotropic HFC / PFC (perfluorocarbon) blend used as a replacement in R503 and R13 ultra-low-temperature refrigeration systems. “Best match” refrigerant for R503. Temperature range: -40 °C … -101 °C.
The discharge temperature of R508B is significantly lower than that of R23, which extends the service life of the equipment.
R508B gas applications and use
R508B is used in industry, research and biomedicine in hospitals, archives and laboratories, for example to ensure proper storage of laboratory samples.
Alternative refrigerants to R508B gas
Replacement or alternative refrigerants: R23 and MO89
