R‑404A
The refrigerant REFRIX 404A is a blend of HFC 143a, HFC 125 and HFC 134a. For its physical and thermodynamic properties it is considered as a possible alternative to the refrigerant R 502, despite not being considered as a "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.
