Three solutions for VOC reduction

More environmentally friendly atomizer cleaning in the painting booth

One of the most important environmental goals in the industrial painting process is the reduction of VOC (volatile organic compound) emissions. Increasingly strict limits shift this onus onto plant operators worldwide. With the new EcoBell PurgeBox purging system, the fully automatic EcoBell Cleaner D2 atomizer cleaning device, and the VOC-free cleaning agents of the EcoFlush Zero product family, it is possible to greatly reduce VOC loads.

Clean atomizers in just 15 seconds

For a perfect painting result, paint contamination must be regularly removed from atomizers. The cycle time in the painting booth is all the 
EcoBell Cleaner D2 needs. It uses the non-productive time during which the next body is being transported into the painting booth as the time window for the process. After just 15 seconds, the atomizer is clean. The EcoBell Cleaner D2 is thus twice as fast as its predecessor model, and VOC emissions are reduced by 94 percent. The three innovative rotary nozzles in the cleaning device clean the atomizer using a mixture of air and cleaning agent, which reduces detergent consumption by 90 percent. In addition, the fog made up of paint and detergent that is produced during cleaning process is routed through a labyrinth in the integrated mist eleminator so that drops form on the walls and flow into a container for easy disposal.

In two-component zones, it will be possible to significantly reduce VOC emissions by means of flushing and cleaning processes if an EcoBell Cleaner D2 is combined with an EcoBell PurgeBox instead of a funnel.

60 percent less VOC during 2K color changes

The new EcoBell PurgeBox is the cleanest solution on the market for two-component (2K) applications. For the first time, a purging system can collect almost all solvent-based 2K paints and purging media. This has a positive effect: the VOC load in the booth due to color changes is reduced by up to 60 percent. This is possible since the new system does not have the usual funnel, and purging the funnel always results in a lot of VOCs being released. Instead, a bell disk retracts the atomizer into the box. This is equipped with special filter mats, which collect the majority of the paint. The almost clean purging medium flows downwards, and can be disposed of without any problems via a collecting pipe.

Outstanding cleaning result, low consumption

More and more VOC-free cleaning agents are being used in paint shops for water-based paints, however their cleaning performance varies. To eliminate even the possibility of problems due to contamination, Dürr has collaborated with the BASF subsidiary Chemetall to offer VOC-free cleaning agents precisely tailored to its application technology. The detergents of the EcoFlush Zero product family produce the best purging and cleaning results with less consumption. VOC-free detergents are usually mixed with demineralized water in a concentration of 3 to 5 percent. Some EcoFlushZero products, on the other hand, only needs a 1.5 percent concentration. This not only reduces consumption, but also the costs for transport and storage. The low-odor, non-flammable products do not contain any toxic substances and do not foam at room temperature.
