Low GWP Alternatives

R448A (N40)


R448A (SolsticeĀ® N40) is a non-flammable HFO blend, used as a replacement for R404A and R22 in low and medium temperature refrigeration applications. It provides an excellent combination of low Global Warming Potential (GWP) and high energy efficiency and offers reduced compressor discharge temperature at medium and low temperature conditions.
