Precise powder enamel application with a robot has many benefits, such as :
– lowest specific enamel consumption
– strongly reduced over-spray
– small factory footprint
Below a short video of a recently commissioned system for baking ovens with Nordson Encore PE spray gun and Encore LT gun controller by Noto Finishing.
In January 2003 Nordson Benelux B.V. delivered upon request by Senter together with a consortium of four other Dutch companies, a complete boiler enameling plant based on Ferro’s electrostatic dry powder enamel technology to Leov Company in Veles, Macedonia in order to replace their environmental unfriendly galvanizing process.

Introduction
Hot water tanks, which are typically used for (solar) boilers and water heaters, may be manufactured from either stainless steel, copper or mild steel.
The selection of the appropriate substrate depends on many factors, such as the annual production volume, the average dimensions of the tanks, expected water quality, desired product life and raw material cost.
Due to the ongoing price increases of stainless steel & copper, there is nowadays a worldwide trend towards manufacturing hot water tanks from mild steel.
HWT’s made of mild steel need to be coated internally, either with zinc, powder coating, nylon or enamel to protect it against corrosion.
According to a publication by the CISP, in which the various corrosion protection methods were compared, porcelain enamel provide the best protection (read longest life) against corrosion by boiling water.
