R125 Refrigerant – Klea® 125

R125 Refrigerant - Klea® 125R125 refrigerant is a main building block for blended refrigerants used as replacements for R-502 and R-22. These blends include Klea® 410A which has become a leading replacement for R-22, Klea® 407C which was one of the first commercially available blends suitable for both retrofit and original equipment use of R-22 systems and Klea® 407A, a lower GWP alternative to Klea® 404A and Klea® 507.
