RS-45 (R434A)

RS-45 (R434A)

ODP: 0 GWP: 3245
RS-45 (R434A) is a non-flammable blend of R125, R143a, R134a, and R600a. RS-45 can be used in a wide range of applications in new and existing systems thanks to its high cooling capacity. RS-45 is compatible with both the traditional and new synthetic lubricants. RS-45 is suitable for use with mineral (MO), alkylbenzene (AB), and polyolester (POE) oils. While there is no need to change the oil when converting from R22 to RS-45, compressor manufacturer’s recommendations should be followed.
