- The Transition to A2L Refrigerants: What You Need to Know
Both R-454B and R-32 are A2L refrigerants, which are slightly flammable but non-toxic By comparison, R-410A is an A1 refrigerant, which is non-flammable and non-toxic The switch to A2L refrigerants brings along some additional requirements, which we outline below Why R-454B?
