Product description:

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.
