Carbon dioxide (CO2) is colourless, odourless and tasteless gas widely spread in the nature.

Carbon dioxide occurs in three aggregate states – gas, liquid and solid. At low temperature (-78.5 oC), carbon dioxide changes from solid state to gas or from gas to solid state (also called dry ice) by missing the medium liquid state. Carbon dioxide obtains a liquid state only under higher than 6 atmospheric pressure (in cylinders, carbon dioxide is pressed with 65-70 atmospheric pressure).

Carbon dioxide is used as protective gas in welding metals. It is suitable for processing untreated and low-treated steel. It is also widely used in food industry. Carbon dioxide produced for welding meets requirements of LST EN ISO 14175 standard (attributed to C1 group).

Carbon dioxide is filled ingrey coloured cylinders.


We offer to purchase carbon dioxide in:

We can fill the cylinders of other volumes as well. The clients buying a considerable amount of carbon dioxide are supplied with special storage tanks for the product and carbon dioxide is delivered with semitrailers.

  • 13,4 l cylinders (10 kg);
  • 20 l cylinders (14,4 kg);
  • 50 l cylinders(37 kg);
  • Euro-cylinders;
  • Liquid carbonic dioxide (in tons).

Fields of industry:

Shielding gas in MIG/MAG welding (MAG process) – CO₂ is used as a shielding gas when welding steel. It protects the weld pool from oxygen and nitrogen, improves penetration, and reduces welding costs.

Flux-cored arc welding (FCAW) – used as a shielding gas with self-shielded or flux-cored wires, especially for welding structures and thick metal plates.

Plasma and laser cutting – in some technologies, CO₂ is used as an assist gas to improve cut quality or reduce oxidation effects.

Surface treatment and thermal processes – CO₂ can be used as an inert atmosphere or cooling medium, for example, for cryogenic surface cleaning before or after welding.

Safety

Unprotected skin contact with carbon dioxide can cause cryogenic frostbites. The places of production should be ventilated. More information on safe handling of carbon dioxide is provided in the material safety data sheet
