Refrigerant 404a
Refrigerant Gas R404A is a colorless odorless mixture of three hydrofluorocarbon compounds in azeotropic proportions. Azeotropic mixtures have sharp boiling points instead of boiling over temperatures range, which is the case with most mixtures. It is a long life substitute of R502, harmless to Ozone. It is mainly used in low and middle central commercial air refrigeration system and in trade refrigeration equipment.
