R134a Refrigerant – Klea® 134a

49518 - Web logos Klea-03
Widely accepted as the most appropriate alternative for R-12 over the majority of the application range for both retrofit and new equipment. A very good match to R-12 for air conditioning, high and medium temperature usage. It can be used in hybrid cascade systems for supermarkets and is being used in some of the HFO blends in order to bring lower flammability and better efficiency.
