RS-24 (R426A)
ODP: 0
GWP: 1508
RS-24 (R426A) is a non-flammable blend of R134a, R125, R601a, and R600. RS-24 is a drop-in replacement for R12 with lower discharge temperatures, reducing degradability of the lubricant in the system.
RS-24 is compatible with all materials commonly used in refrigeration systems previously charged with R12. In general, materials which are compatible with R12 can be used with RS-24. It is recommended to check equipment manufacturer’s retrofit literature and obtain recommendations from equipment manufacturers with regard to material compatibility. RS-24 is compatible with mineral (MO) and alkylbenzene (AB) oils found in R12 systems. It is also compatible with synthetic oils such as polyolester (POE) and polyalkylene glycol (PAG). While there is no need to change the lubricant, compressor manufacturer’s recommendations should be followed.
