Technical overview
R404A refrigerant for commercial refrigeration
R404A is a near-azeotropic HFC blend used in low- and medium-temperature refrigeration equipment. It is associated with commercial cooling applications such as compatible cold rooms, display cases and freezer systems. Check the equipment specification before ordering; inclusion in a refrigeration catalog does not make it suitable for every cooling application.
