Feiyuan brand China top quality supplier refrigerant gas R32

R32 is proposed to be used in some air conditioning equipment which currently uses R410A so this bulletin is an introduction to this refrigerant. It is mildly flammable and has similar performance and operating conditions to R410A. It has a lower global warming potential (GWP) than the commonly used HFCs.

Characteristics
R32 is difluoromethane (methylene fluoride) and it is an HFC type refrigerant. R32 has been used for many years as a component of both R407C and R410A. It is flammable on its own, but not when mixed with the other components of these blends.
•Work in a well-ventilated area;
•Eliminate sources of ignition within 3 m of the system and associated service equipment;
•Use a suitable detector to warn of a build-up of flammable refrigerant in the air;
•Have a fire extinguisher available;
•Ensure your recovery machine is safe to use with flammable refrigerant;
•Use leak detection spray or a safe, sensitive electronic leak detector;
•If you need to un-braze connections ensure you have recovered the system onto a vacuum and filled with a charge of dry nitrogen to a slight positive pressure before un-brazing;
•When evacuating the system ensure the vacuum pump is in a well-ventilated area (or outside) and control it by a switch outside the 3m area. You should refer to the detailed information provided by the suppliers or training providers.
