DynaLayer – The first curtain coater with outstanding coating quality to work completely without additional enclosure
- Stable process and product quality
- Low running and maintenance costs
- Optimum runability for online and offline installations
The new curtain coater achieves a particularly uniform coverage of the web with just one layer. In addition, unlike previous curtain coaters, DynaLayer can be operated without an enclosure, which not only improves access for the operator but also results in much lower costs for operation and maintenance.
At the same time, the latest generation of curtain coaters allows even more uniform CD and MD profiles to be achieved. This has a positive effect on the printability of the paper and produces a more homogeneous printed image. The number of costly web breaks is also reduced when using DynaLayer thanks to the non-contacting application of the coating.
“Several manufacturers of specialty papers have already reported cost savings to us as a result of considerably reduced color consumption,” explains Christoph Henninger, Product Manager Coater Stations at Voith. The uniform color application by the new curtain coater is also useful when producing white board with a two-layer coating. To achieve a high surface opacity in these kinds of papers, most manufacturers currently use titanium dioxide. However, this is an expensive pigment, so any reduction improves the economic efficiency of the system. For example, a paper manufacturer that has been using the DynaLayer for some time now cut the costs for titanium dioxide by about half for the production of board with a white top layer by completely dispensing with the titanium dioxide in the bottom coating layer while ensuring the same quality of coverage. A similar effect was achieved by a manufacturer of specialty papers that is saving up to EUR 150,000 per year thanks to the uniform application of the coating of the expensive functional layers, because the total color application could be reduced as a result of better CD profiles.
According to the individual requirements and applications of paper producers, Voith offers the new curtain coater in various models. This means that DynaLayer can be supplied as the latest model without enclosure or in the previous variant with enclosure. The coating unit generally achieves a perfect application with just one layer. If required, for example in the case of two different coatings, DynaLayer is available as a two-layer concept that can also be easily retrofitted.
