Valmet is a genuine one-stop supplier of sizing and coating technology, including related chemical systems. The intelligence behind paper and boardmaking lines can be found in the elements that go beneath and below the machine themselves. For example, a functioning air removal system is essential in a coating or sizing supply system to reach the desired level of end product quality.
Optimized mechanical design and automation guarantees functionality in all conditions, especially during start-up and after web breaks. The cleanliness of equipment and piping receives special attention in the design of chemical systems, along with energy efficiency, minimizing effluents, and recovery.
OptiStarch and OptiColor surface size and coating color preparation systems cover complete coating kitchens, comprising unloading, processing and storage of coating color components, metering and dosing of components in the mixer, and storage of products. The process includes optimized equipment for sub-processes like agitating, metering, screening and mixing. Coating color recovery systems based on Valmet's ultrafiltration technology can also be included in order to recycle effluents containing coating. Valmet's technology offers a safe way to reuse recovered coating without any additional chemicals, minimizing coating color losses.

Valmet has equipment for any supply system including machine tanks, pressure screens, deaerators, automated coarse strainers and effluent recovery systems. For demanding applications, several double and return flow screening concepts will be added to the system.
