R407C refrigerant


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

Physical Propertiesl: 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. BecauseODP is zero,it doesn't destroy atmosphere ozone.

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.

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

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