KLEA®407C

Trademark：KLEA

Introduction：

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 is 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
Please note that not all products are available in all markets.
