What is liquid CO2 (LCO2)?


At Atmospheric pressure CO2 is an odurless gas. If you increase the pressure the gas will turn into a clear liquid. By increasing the pressure and temperature to a point above 73 Bars and 31 degrees Celsius, CO2 turns into its supercritical state. At the liquid state, CO2 has a solvent strength in the range of acetone and hexane . The viscosity and surface tension is orders of magnitudes lower than water and organic solvents.

By altering the temperature and pressure or by including an additive, the solvent power of CO2 can be optimized for a specific application.

Using SiOx machines technology, it is possible to replace processes traditionally carried out in benzene, perchloroethylene, hydrocarbons and other toxic and/or flammable solvents by environmentally friendly, non-toxic carbon dioxide under pressure.

CO2 under pressure has excellent cleaning properties. It is safe to work with and reaches the smallest structures due to very low surface tension. Goods can be placed in the machine in dry state, and after the treatment they are still dry.

Supercritical CO2 is most well known in the field. We offer liquid CO2 (LCO2) technology which has all the advantages of supercritical CO2 – but at significantly lower investment costs.
