Daikin's R407H is a low GWP refrigerant designed as a substitute for R404A and R507. It is a cost efficient alternative to HFO-Blends, and classified as non-flammable (ASHRAE 23 A1-class).
R407H shows similar performance to R404A/R507 in real world applications, with a GWP below 1500 and without the need for costly HFO components. R407H can generally be used without major changes to existing systems, and can be considered a "drop-in" solution in many cases.
