UN Number
R290 is mainly used to replace R22, R502 refrigerant for use in low-temperature refrigeration equipment (less the amount for filling cryogenic refrigeration equipment), R290 refrigerant is low with an important component; R290 is compatible with the original system and lubricants.
Storage and transportation
R290 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 .
