KLEA®125 is a main building block for blended refrigerants that are being used as replacements for R502 and R22. These blends include R410A which has become a leading replacement for R22, KLEA®407C which was one of the first commercially available blends suitable for both retrofit and original equipment use of R22 systems; KLEA®404A which is a popular replacement for R502, (in both Europe and the US), and KLEA®507, which is closely related to KLEA®404A, but operates at slightly higher pressures.
Please note that not all products are available in all markets.
