R 407A
Refrigerant Fluids | R 407A
The refrigerant R 407A is a blend of HFC 32, HFC 125 and HFC 134a. Similar in capacity and efficiency, it is considered as a possible alternative to the refrigerant R 22, despite not being a direct “drop-in.” Being a zeotropic substance, vapour composition is altered during the vapour phase with possible effects to the plant; hence, the need to load the blend only during the liquid phase.
