Honeywell Promoting New Refrigerant Solstice N40 as Alternative to R404A

Honeywell has developed a new refrigerant, Solstice N40, as an alternative to R404A, which has high global warming potential (GWP). The new refrigerant, registered as R448A and given the brand name Solstice N40 by Honeywell, is nonflammable and highly efficient with lower GWP than standard hydrofluorocarbon (HFC) refrigerants.
