Trademark：KLEA

Introduction：

A viable alternative to R-22 and R-502 for new and retrofit applications.
It is a good refrigerant for supermarkets and other commercial applications. For a reduced GWP, KLEA®407A offers a good alternative to KLEA®404A.
Composition (wt%) R-143a/R-125/R-134a = 52/44/4.
