EcoCVac Dry Cleaning Without Compressed Air

Dürr Ecoclean GmbH has introduced EcoCVac for innovative dry cleaning without compressed air. Machined powertrain components undergo intermediate cleaning to safeguard the quality of subsequent process steps. This is typically done by means of compressed air, which must be generated at a high expense of energy. The new EcoCVac offers an effective dry cleaning system that eliminates the need for compressed air. Apart from delivering enhanced process reliability, the system can provide energy savings of more than 50 per cent. As maintenance of the working chamber is minimised, it also improves the machine availability. The EcoCVac 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, a powerful airflow is directed through it, thereby '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, allowing both to be discharged separately via a collecting bin and a flume, respectively. In addition to the obvious cost benefits, the EcoCVac shines with its improved process reliability. As the chips are removed not only from the part but also from the work chamber, the risk of re-contamination is minimized. The chamber must hence be cleaned less often, and at a clearly reduced cost and effort. Moreover, unlike conventional compressed-air systems, there are no nozzles to be aligned relative to the part, e.g., during commissioning or after a collision. The system's availability rate is thus further improved.
