RS-51 (R470B) R404A, R22 & R507 Replacement Refrigerant, 24 Pounds

The LOWEST GWP, NON-FLAMMABLE Retrofit Replacement for R404A and R507

ComStar International Inc.’s RS-51, with the ASHRAE designation of R470B, is new to the U.S. market. RS-51 (R470B) was initially invented for the European market due to their stricter Global Warming Potential (GWP) reduction regulations and financial incentives for using low-GWP refrigerants. RS-51 is the lowest retrofit refrigerant with a GWP of 717 to replace R404a and R507 in existing systems. These refrigerants have a GWP of 3943 and 3985 respectively (AR5).

RS-51 (R470B) was formulated to be safely compatible with R404A and R507 compressors, system components, and oils while providing exceptional cooling properties. RS-51 offers similar performance to R404A and R507, but with a lower discharge pressure than R448A and R449A.

RS-51 (R470B) is an HFO (HydroFluoroOlefins) blend, which is the environmentally friendly alternative to the commonly used HFC blends in other refrigerants. RS-51 (R470B) is EPA SNAP-approved and A-1 ASHRAE certified as non-flammable and non-toxic. These facts make RS-51 (R470B) the perfect replacement choice.
