R-449A Refrigerant
R449A is a next-generation HFO/HFC refrigerant blend (R32 / R125 / R134a / R1234yf) designed to replace high-GWP refrigerants such as R404A and R22 in commercial refrigeration and air conditioning. With a Global Warming Potential (GWP) of ~1397, it reduces climate impact by more than 65% compared to R404A, while delivering excellent cooling efficiency and reliable system performance.
