Refrigerant R407H – replacement with a lower GWP
Refrigerant R407H is a lower GWP replacement for R404A and R507A. It is a cost-effective alternative, which is classified as a non-flammable system (ASHRAE 23 Class A1).
According to the European F-gas Regulation (EU 517/2014), the use of the aforementioned refrigerants should be cut back heavily in order for the CO2 reduction goals to be achieved by 2030.
In practical applications, R407H is equal to R404A and R507A in performance, but its GWP is only 1,495 and its use requires no expensive HFO components.
R407H can usually be used in existing systems without major modifications, and it can serve as a “drop-in” solution in many cases. (See more: lower edge of this page.)
