Packing specification: 7kg,670Kg/926L, 30Kg/40L steel cyinder
Uses: as refrigerating fluid
Our Advantages over other factories in the production of refrigerant gas
We are the supplier of many big air conditioner and commerical condioning customers.
The cylinders have CE/DOT/KGS certificate
New technology cylinder, 100% safety no leakage
We have our own labs to guarantee the gas purity 99.91%-99.97%
R134A gas has REACH certificate
We have R32,R152,R22,R134A,R410A,R407C,R404A…
R32 is a new type of environmentally friendly refrigerant, with higher pressure than R410, fast cooling speed and good effect, so it is used. However, it is flammable and explosive, and the operation must be standardized, and air cannot be mixed, otherwise the consequences may be serious.
Application: Difluoromethane is a coolant with zero ozone depletion potential. Difluoromethane and pentafluoroethane form an azeotropic mixture (called r-410a), which is used as a replacement for chlorofluorocarbons (also known as freons) in new coolant systems, mainly to replace
hcfc-22
as a compound medium and low temperature mixed refrigerant. Although it has zero ozone depletion potential, it has a high global warming potential, which is 550 times that of carbon dioxide on a per 100-year basis.
