BMW Group introduces electrically powered exhaust purification in first paint shops

The BMW Group is now powering exhaust purification in its first paint shops electrically. Thanks to a new method, the high temperatures needed for the thermal purification of exhaust from paint booths and drying areas can now be generated by electricity. With that, a further production process can now be carried out without using natural gas.

Michele Melchiorre, Head of Production System, Planning, Tool Shop, Plant Construction at the BMW Group: “For other energy-intensive paint shop processes, such as vehicle drying and water heating, solutions already exist for working without natural gas. So, electric exhaust purification is the final steppingstone for the BMW Group to run its paint shops on regenerative energy in the future.”

The first systems have already been tested at Plant Regensburg and BMW Brilliance in China, and Plant Dingolfing has converted a painting line for the new system to be used in series production. When the BMW Group’s newest plant goes on stream in Debrecen in 2025, it will use only the new method.
