Application Area:

R404A, as a medium and low temperature refrigerant, is widely used today as an alternative to R502. Commonly used in cold storage, food refrigeration equipment, vessel refrigeration equipment, industrial low temperature refrigeration, commercial low temperature refrigeration, transportation refrigeration equipment (refrigerated vehicles, etc.), refrigeration condensing units, supermarket display cabinets and other refrigeration equipment.

Storage and transportation (safety classification A1) :

The steel cylinder used to store R404A refrigerant is a type of pressure vessel, so keep it away from fire, heat sources, and direct sunlight, store it in a cool, dry and ventilated warehouse. Handle lightly to prevent crushing, collision, and prevent breakage to the cylinder or accessories such as valve, etc.

Lubricant recommendations :

Compatible with ester lubricants (POE)

Tips: Selection of refrigerating oil for different types of equipment and different scenarios shall follow the recommendations of the refrigeration compressor and refrigeration (conditioning) equipment manufacturers, or be determined based on the equivalent design and technician requirement according to the specific conditions of the refrigeration compressor and refrigeration equipment, that is, using only the refrigerating oil that matches the equipment or its application purpose.
