New cleaning process uses supercritical CO2
Intended for fine and ultra-fine cleaning, the EcoCO2 from Dürr Ecoclean is the first-ever process that uses carbon dioxide in its supercritical state to treat small parts of complex geometry.
The technique produces outstanding results in medical, nano and semiconductor applications, for example, cleaning and drying component surfaces efficiently.
Used at the appropriate temperature and pressure, CO2 exhibits optimum oil-dissolving properties. nlike conventional 'snow jet' cleaning systems in which CO2 is converted into solid ice crystals that act as a blasting medium, the EcoCO2 uses carbon dioxide in both its liquid and supercritical states. Foreign matter removed from the component is separated from the CO2. No residue of the cleaning agent remains on the processed part, which emerges from the machine at room temperature.
