Due to existing regulation related to the direct Global Warming Potential (GWP) of refrigerants, there is increased interest by equipment owners in using lower GWP refrigerant options in order to reduce these systems’ total carbon footprint.

R449A is a low GWP hydrofluoro- olefin(HFO)-based refrigerant developed to replace R-404A/R-507A in appliances with medium or low refrigeration temperatures. It is available for both retrofit of existing R-404A/R-507A equipment as well as a suitable replacement option in new equipment.

R449A offers improved energy efficiency and environmental properties versus R-404A/R-507A, with a Global Warming Potential (GWP) of 1397 (vs. 3922 for R-404A). R449A refrigerant has a zero Ozone Depletion Potential (ODP).

Many R-404A/ R-507A systems can be converted to operate using R449A allowing existing equipment to continue to operate safely and efficiently with a greatly reduced environmental impact.
