Automated application with waterbased coatings and reduced equipment costs
WAGNER adds special variants to the range of high-speed rotation atomizers with external charging for the processing of water-based paints .
From metal workpieces to automotive components and wood : WAGNER ' s highspeed rotary atomizers can be used in numerous industrial sectors and achieve extremely efficient coating results on both small and large workpieces .
The TOPFINISH Bell 1S and TOPFINISH RobotBell 1 products available to date are equally well suited as all-round units for water-based and solvent-based coatings . Both models are now available as variants with external charge with the suffix " ECH " (" external charge "). They have been specially developed for demanding applications with water-based paints , where a particularly high coating quality is required .
The external charge of the coating material is decisive here : The high voltage emitted via the electrode ring ionizes the ambient air in such a way that the sprayed material is charged . The grounded workpiece is electrostatically coated . Compared to internal charging , external charging has the considerable advantage that the overall system does not have to be specially insulated for use with water-based coatings , ultimately to ensure a safe coating process . The equipment costs for water-based coating applications are therefore significantly reduced .
Compared to the WAGNER market competitors , these two models can process even higher-viscosity materials too . Thanks to the modular concept , they can also be converted in just a few minutes to a version with internal charging for use with solventbased coatings , without having to modify the complete structure of the overall system .
Various designs
WAGNER has extended its range of highspeed rotation atomizers to serve the growing demand for automated liquid paint applications for the different motion technologies available today . The TOPFINISH RobotBell 1 ECH is mounted on a robot arm , while the TOPFINISH Bell 1S ECH is specially designed for use with reciprocators and linear axes systems . The proven RBC 1E control system is available for both versions .
Flexible application and high efficiency
Just like the already proven versions with internal charging , the new versions also enable large spray pattern variations ( 70 - 800 mm ). Alternative disk sizes and adjustable steering airs are available , which can be adapted to suit the respective workpiece geometry and also the material used .
An internal and external flushing device of the bell disk , as well as the direct disposal of excess material via a drain valve , ensure short colour change times - for fast cycle times in highly automated coating .
Depending on the material , flow rate and workpiece , an application efficiency of over 80 % can be achieved thanks to the very fine atomization . Compressed air consumption is around 20 % lower with all WAGNER high-speed rotary atomizers than with comparable products . An exhaust air concept , which discharges the exhaust air to the rear , additionally optimizes the coating result .
Easy maintenance without special tools
WAGNER uses the same basic components for all high-speed rotary atomizers , for example for the turbine or bell disks and the easily replaceable valve blocks . The spare and wear parts are also identical .
The simple operation , robust technology and durable components made of stainless steel reduce the effort required for assembly and maintenance and therefore also the operating costs .
