R404A

The HFC R-404A is one of the most commonly used refrigerants in the United States and in the world. You can find it most commercial refrigerators/freezers, in vending and ice machines, in refrigerated transport, and in specific industrial applications.

404A was originally implemented as a replacement option for the now banned CFC R-502. R-502 was widely used throughout all of the applications we mentioned above until 1995/1996 when it was phased out entirely due to it’s Ozone Depletion Potential (ODP). While 404A has been around for decades it’s future may be short lived due to it’s high Global Warming Potential (GWP).
