Colour Changer, ECOLCC

The EcoLCC colour changer reduces paint losses from more than 40 ml to 8 ml per colour change and shortens the colour change time to less than 10 seconds. The robots of the AIR zone in the exterior painting area DL2 at VW Saxony were converted to the new technology in April 2009. In the automatic painting installations of automobile manufacturers and subcontractors the paints must be provided flexibly for the painting in the colour wanted by the customer. For this, a purgeable colour change system is required. The colour change must occur quickly, paint losses must remain minimal. With the EcoLCC colour changer by Dürr, each paint colour is activated by docking to the respective paint valve. The EcoLCC does not have any common paint ducts anymore. The paint hose to the paint atomizer now has the same length for all paints, paint carryover or the intrusion of paint through defective valves is technically impossible. The process of the colour change is a push-out process. In the push-out process, the paint valve is closed already before end of painting and the paint material that is still in the colour hose is pressed towards the atomizer with solvent. EcoLCC colour changers by Dürr are already in use in India and Russia. The Dürr Group is a supplier of plant and equipment that commands leading global market positions in its areas of activity. Business with the automotive industry accounts for about 85% of its sales. Dürr also supplies innovative manufacturing and environmental technologies for the aircraft, mechanical engineering, chemical and pharmaceutical industries.
