Industrial gas specialist the Messer Group has revealed it is supplying liquid carbon dioxide to German auto-parts manufacturer Burkhardt GmbH in Vaihingen/Enz, for cost-effective and resource-saving cleaning applications using dry ice.
Burkhardt GmbH has shown that industrial cleaning with water is increasingly giving way to resource-saving cleaning with dry ice snow, as it added a unit with CO2 pre-cleaning to its operations – which include the manufacture of high-quality auto parts for the interiors of prestigious German cars.
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.
For its part, Messer is supplying the liquid carbon dioxide and is promoting the further development of such 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.
