RS-70 (R453A)

RS-70 (R453A)

ODP: 0 GWP: 1765
RS-70 (R453A) is a non-flammable blend of R134a, R125, R32, R227ea, R601a, and R600. RS-70 is a suitable drop-in replacement for R22 at high and low temperatures. RS-70 is compatible with all materials commonly used in refrigeration systems previously charged with R22. In general, materials which are compatible with R22 can be used with RS-70. It is recommended to check equipment manufacturer’s retrofit literature and obtain recommendations from equipment manufacturers with regard to material compatibility.
