[Usage] R744 is usually known as CO2, Carbon dioxide, Dry ice. R744 is Precursor to chemicals, Foods (Beverages, Wine making), Inert gas, Fire extinguisher, Supercritical CO2 as solvent, Agricultural and biological applications, Oil recovery, Bio transformation into fuel, Refrigerant, Coal bed methane recovery, niche uses. R744 is green refrigerant gas, friendly to our earth and air. It is ideal refrigerant gas to substitute HFCs.

[packing] R744 has two packings: 23/30kg/cylinder and ISO tank. Its cost is low but packing cylinders is expensive. So we recommend the oversea buyers buy cylinder packings in first 3 shipments and then buy in ISO Tank.
