Carbon dioxide (liquid) – CO2

Carbon dioxide under normal conditions is a colourless, odourless gas, and of slightly sour taste. It is denser than air, inert, and non-combustible. It is liquefied at a pressure of 15 to 17 bar and temperature -30 to -35°C. CO2 is not toxic and is present in the atmosphere at a concentration of about 0.03 vol. %. Higher concentrations are dangerous due to the reduction of oxygen in the air.

Belinka Perkemija produces liquid CO2 to the quality required by the food industry.
