Dürr’s EcoCVac dry cleans powertrain parts

The EcoCVac from Dürr Ecoclean is a dry cleaning system that eliminates the need for compressed air. Apart from delivering enhanced process reliability, the system can deliver energy savings of more than 50% in typical applications, which include the cleaning of machined powertrain parts.

EcoCVac relies on newly developed vacuum suction technology. This ensures that contaminants are removed not just from the part but also from the work chamber, usually within 1.5 to 3 seconds.

The system comprises a pressure vessel in which a vacuum is maintained permanently. This vessel is connected by a pipe to the vacuum chamber in which the part is placed. Once the chamber is closed, powerful airflow is directed through it, 'entraining' the chips sticking to the part and taking them into the vacuum vessel. A chip clean-out device integrated nearby separates chips and emulsion.
