KLEA®507

Trademark：KLEA

Introduction：

A viable alternative to R-22 and R-502, comprising R-125 and R-143a, for new and retrofit applications. KLEA®507 offers good benefits in flooded systems. For a reduced GWP alternative, KLEA®407A is a good refrigerant in supermarket and other commercial applications.
Composition (wt%) R-125/R-143a = 50/50
