Cleaning auto parts without water

Cleaning with dry ice snow saves resources

Burkhardt GmbH in Vaihingen/Enz shows that industrial cleaning with water is increasingly giving way to resource-saving cleaning with dry ice snow. The manufacturer of high-quality auto parts for the interiors of prestigious German cars has added a unit with CO2 precleaning to its operation. The automotive supplier uses dry ice snow with so-called cold burners to clean parts for radio/AC surrounds as well as for other applications in car interiors. Messer, the industrial gases specialist, is supplying the liquid carbon dioxide and is promoting the further development of this technology by working with scientific establishments like the Fraunhofer Institut. Cleaning with carbon dioxide not only reduces water consumption, but also does away with the energy costs associated with the time-consuming drying process as well as wastewater treatment.
