Alternative R502, mainly used for cold storage, food freezing equipment, marine refrigeration equipment, industrial cryogenic refrigeration, commercial low temperature refrigeration, transport refrigeration equipment (refrigerated trucks, etc.), refrigeration condensing units, supermarket display display cabinets and other refrigeration equipment.
Storage and transportation
R404A refrigerant cylinders for pressurized containers should be stored away from fire, heat, avoid direct sunlight, usually put storage in a cool, dry and ventilated warehouse; handling with care, light disposal to prevent damage to the cylinder and valves and other accessories .
R404A refrigerant is an alternative to freon R22 and R502 of the most common industry standard refrigerant (usually a low-temperature refrigeration systems) newly installed on the cooling unit, R404A is closest to the operation of R-502, it applies to all R-502 can operate normally environment, R404A recognition and use of the vast majority of global refrigeration equipment manufacturers. However, due to R404A and R502 and R22 physical and chemical properties, the theoretical cycle performance and compressor oil, etc. are not the same, so for the initial installation for R502 and R22 refrigerant refrigeration equipment sales service, if you need to add or replace refrigerant still You can only add R502 and R22, usually can not be replaced directly with R404A R502, R22.
