E-Scrub making headway in the US – Eisenmann clinches major deal

Böblingen, Germany, June 13, 2013 – BMW Group is investing approximately 900 million US dollars to expand its American production facility in Spartanburg, South Carolina and increase capacity. The factory produces BMW’s ‘X’ range, and the new paint shop will be equipped with Eisenmann technology. This move comes in response to growing global demand for the Munich marque’s premium vehicles, and the paint shop is designed for a maximum throughput of 30 units an hour or 150,000 per year.

The automobile giant will implement Eisenmann’s E-Scrub for the first time, a system that utilizes electrostatic charge to separate paint overspray from exhaust air, conserving energy and resources. This will be the first E-Scrub system to be installed in North America. “We are delighted that our solutions lead the pack when it comes to implementing clean, eco-friendly production methods while at the same time expanding capacity,” says Bruno Casorati, Senior Vice President, Automotive Systems at Eisenmann Anlagenbau.

The E-Scrub will be incorporated into the standardized Integrated Paint Process. This uses a modified base coat that eliminates the need for primer application and curing. The base coat is applied on top of the e-coat and cured ahead of the clear-coat stage. The shorter, simpler process increases productivity and reduces energy and material consumption. E-Scrub supports this process, achieving savings of up to 75 percent, which contributes significantly to improving the eco-footprint of every vehicle produced.

The paint shop will be fitted with an Eisenmann Vario Shuttle dip pre-treatment system, already in operation in other BMW plants worldwide. The freely programmable conveyor for dip coating is highly flexible and can be easily adapted to any car body. Eisenmann is to build the entire conveyor system, including the electrified monorail employed at the sealing stage: its ingenious rotating hangers give assembly workers easy access to the underbodies, improve safety, and offer superior ergonomics. Eisenmann will also install a regenerative thermal oxidizer for exhaust gas purification.

Installation of the new paint shop will commence in the second half of this year, and commissioning is scheduled for January 2015.

About Eisenmann

Eisenmann is a leading global provider of industrial solutions and services for surface finishing, material flow automation, thermal process technology and environmental engineering. A family-run business founded in 1951 in southern Germany, Eisenmann develops and builds custom manufacturing, assembly and distribution plants that are highly flexible, energy- and resource-efficient – and deployed by enterprises throughout the world for more than 60 years. With a workforce of 3,700 in Europe, the Americas and BRIC countries, the company posts annual revenues of approximately 640 million Euros (2012).

Compared to conventional systems, the energy-efficient E-Scrub requires a very low differential pressure in the air flow system. Water consumption, particulate emissions and waste quantities are all significantly lower than with other systems.
