Description
United R404A is a HFC blend, used as a replacement for R502 and R22 in low and medium temperature refrigeration applications. Although it is a popular refrigerant, R404A is under great scrutiny due to its high Global Warming Potential (GWP). This has led to an increased focus on lower GWP alternatives such as R407F and R407A, along with newer alternatives such as R448A and R449A.
