Refrigerant R450A


R450A refrigerant is a mixture of 42% R134a and 58% HFO-1234ze that is non-flammable, has an ODP of zero and a GWP of approximately 573, and is listed under the EPA SNAP program to replace ozone-depleting substances. R450A refrigerant is a non-combustible mixture of refrigerant.


R450A refrigerant steel cylinder is a pressurized container. Keep it away from fire, heat sources, and direct exposure to sunlight. Usually, store it in a cool, dry, and ventilated warehouse. When handling, light loading and unloading should be carried out to prevent cylinder and valve and other accessories from damage.


R450A is a widely used medium and high temperature refrigerant today, mainly used in retail food refrigeration systems, refrigerated/refrigerated transportation, water coolers, cold storage, industrial process refrigeration, piston and screw chiller and vortex chiller, centrifugal chiller, vending equipment system modification, home refrigerators and freezers, and industrial process air conditioning systems.
