Description
R-449A is a zeotropic HFC/HFO-blend refrigerant (R-32/R-125/R-1234yf/R-134a) developed as a lower global warming potential alternative to R-404A in medium and low-temperature commercial refrigeration applications. It carries a GWP of approximately 1,397 — roughly 64% lower than R-404A (GWP 3,922) — supporting compliance with EU F-Gas Regulation and equivalent regional HFC phase-down requirements. This 25 lb cylinder is packaged for professional refrigeration technician use.
R-449A is suitable for commercial refrigeration systems including supermarket display cases, cold storage, restaurant refrigeration, and refrigerated transport, where equipment has been assessed for R-449A compatibility. As a zeotropic blend, it must be charged as a liquid to maintain correct refrigerant composition; temperature glide should be accounted for during system commissioning. Retrofit from R-404A may require lubricant compatibility verification, filter-drier replacement, and expansion valve assessment — verify with equipment manufacturer guidelines before service.
R-449A is classified as non-flammable (A1 safety class), suitable for use in occupied commercial environments. The 25 lb cylinder includes a standard valve fitting compatible with professional refrigeration service equipment. For use only in systems designed or properly retrofitted for R-449A, by certified refrigeration professionals in compliance with applicable local regulations.
