R507 Refrigerant – Klea® 507
R507 refrigerant is a viable alternative to R-22 and R-502 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
