LOW-GWP BLEND FOR NEW AND RETROFIT SYSTEMS
R449a is a mixture of common hydrofluorocarbons (HFC) and new hydrofluoro-olefin molecule R1234yf (HFO), a composition of R32 (24%), R125 (25%), R134a (26%), and R1234yf (25%) gases. Refrigerant R449a is non-toxic and non-flammable and has been assigned A1 safety classification under EN 378 and ASHRAE 34 standards. Chlorine is not present in R449a, and consequently, it has zero ozone depletion potential (ODP). Its global warming potential (1397) is 64% respectively lower than R404a.
R449a is suitable for new installations as well as for retrofit of existing systems, offering improved energy efficiency and environmental properties.
