Dürr is building an environmentally friendly paint shop for BMW Brilliance Automotive Ltd. in Shenyang, China.
According to the company, the shop will feature RoDip M rotational dip coating in the PT/ED area, reducing energy and chemical consumption. The Integrated Paint Process will eliminate the need for primer and a drying phase. Spray booths will be equipped with the company’s EcoDryScrubber technology, a dry separation method that requires no water or chemicals. The saturated binding material, which is a hazardous waste in conventional processes, can be reused without further treatment.
Heat wheels will be used to recover heat from supply and exhaust air, and a waste heat boiler will recover waste heat from the dryers. The exhaust air stream from the clear coat booth will be purified before leaving the facility. The use of membrane technology in the pretreatment, electro dipping and waste water system, reduces both water consumption and the amount of waste water, the company says.
