Atomizer for Electrostatic Application
Atomizer for Electrostatic Application
Dürr Group has introduced EcoBell3, a new generation of Atomizers for the Electrostatic Application of water-based paints in conjunction with external charging. The performance of this atomizer surpasses its predecessor by far. Its new features not only lead to minimal losses during colour changes and shortened colour change times, they also offer new process technology options. The most important element, however, is that the EcoBell3 is equally suitable for both interior and exterior painting. This was achieved by a very compact electrode ring. With it, the atomizer represents the ideal synthesis between high performance and process flexibility on the one hand, and the lowest complexity on the other. The use of EcoBell3 offers the user considerable benefits. In one of the first orders with this atomizer for a sports car manufacturer, both interior and exterior painting were combined in one zone – the planned capacity of the plant allowed this. The benefit resulting from this was a significant reduction of plant length as well as the number of robots, and hence a reduction of the investment and operating costs. If a division of the interior and exterior painting scopes is needed for different zones – and this is certainly the norm in a paint shop – the use of EcoBell3 allows the work scopes to be distributed among all the robots in a way that optimal utilization takes place. In addition, this opens up the possibility of degrade functionality. This means that the failure of one robot in the painting scope can be covered by the remaining robot – a function that makes the so-called backup zones with manual application superfluous. This also significantly reduces plant length and operating costs.
