Frogen R404A

Frogen® R-404A (HFC-404A) is a non-ozone depleting compound designed to serve as a long-term alternative to Frogen® R-502 (CFC-502) and Frogen® R-22 (HCFC-22) in low and medium temperature commercial refrigeration applications. Applications where Frogen® R-404A is a suitable retrofit refrigerant include supermarket freezer cases, reach-in coolers, display case, transport refrigeration and ice machines.

Usage and Safety Information

Handling Precautions

Keep away from sources of ignition. Take precautionary measures against static discharges. Protect cylinders from damage. Do not drag, slide, roll or drop cylinders. Slowly open valve. Close cylinder valve after each use and keep closed even when cylinder is empty. Never apply heat or flame to any part of cylinder. Avoid inhalation of high concentration of vapours. Avoid contact between liquid and skin and eyes.

Storage Precautions

Store and use with adequate ventilation. Keep in a cool place away from fire risk, direct sunlight and all sources of heat. Avoid storing near intake of air conditioning units, boiler units and open drains. Store cylinders below 45 °C.
