Non-azeotrope (HFC-32/HFC-125/HFC-134a=23%/25%/52%)

1.Physical properties

Under normal temperature and pressuse,R407C is a kind of non-azeotrope fluoro-alkane refrigerant free of chlorine,and a colorless gas.It is stored in a cylinder by compressed and liquefied gas.Because ODP is zero,it doesn't destroy atmosphere ozone.

3.Main usage:R407C is a kind of refrigerant of surrounds-protection model,used in replacing R22 & R502.It has a good nature of cleaning,low poison,non-combustion,good-refrigeration and so on,and greatly used in air-conditioner.

4.Packing:Cylinder packing,net weight 11.3kg,500kg,870kg.also shipped by ISO containers or tanks,its packing category is II.

5.Security:The filled cylinder is under pressure,and ought to be avoided bumping,falling,sunlight exposure and heat source during transport and storage.
