Forane® R-22 refrigerant retrofit solutions

Arkema recommends Forane® 407C, Forane® 407A, and Forane® 427A - The Easy R-22 RetrofitTM as R-22 retrofit options for many R-22 applications. All are SNAP approved. 

When reviewing the various retrofit considerations – GWP, capacity, efficiency, operating pressures, flow rates – you will find that these products represent some of the closest overall performance matches to R-22 available on the market today. R-407C has the closest capacity to R-22 for air conditioning, while R-407A offers performance similar to R-22 in supermarket refrigeration. R427A is a hybrid blend that mirrors R-22's operating pressures, allowing it to be used in a wider range of systems.
