Mihama Refrigerant Gases HFC R-407c

HFC R-407c

All of the R-407-series refrigerants are based on blends of the three HFC refrigerants R-32, R-125 and R-134a. R-407C has been formulated as a good match to the existing HCFC refrigerant R-22 for use in air conditioning, chilling and refrigeration applications and was the first of the R-22 alternatives to be used on a commercial scale. Suitable for retrofit and original equipment usage. Klea® 407C meets the GWP requirements beyond 2030 under the EU F-Gas Regulations for industrial and commercial refrigeration.

Composition (wt%) R-32/R-125/R-134a = 23/25/52
