Ecofrost® 407A (R-407A) is a non-ozone depleting, zeotropic blend of HFC refrigerants R-32, R-125, and R-134a. Ecofrost® 407A is a lower GWP refrigerant, designed for the replacement of R-404A and R-507A (retrofit and new equipment) in medium and low temperature refrigeration. Common applications include supermarket refrigeration, refrigerated transports, and food processing. R-407A can also be used as an R22 retrofit for medium and low temperature refrigeration systems but is not intended for air-conditioning applications nor recommended for use in systems with flooded evaporators. Overall system capacities and efficiencies of an R-407A retrofit will be similar to those of R-22 for the US.
