Refrigerants - KLEA 407C
|
|
| |
All of the R-407-series refrigerants are based on blends of the three HFC refrigerants R-32 (difluoromethane), R-125 (pentafluoroethane) and R-134a described above. R-407C has been formulated as a good match to the existing HCFC refrigerant R-22 for use in air conditioning, chilling and refrigeration applications and is the first of the R-22 alternatives to be used on a commercial scale. Suitable for retrofit and original equipment usage.

Composition (wt%) R-32/R-125/R-134a = 23/25/52
