Coating and Sizing improvements for board and paper making

Upgrade of existing air dryer nozzles to high performance Valmet Air Dryer Nozzles improves the drying capacity. Using efficient air nozzles not only improves drying capacity, but also decreases energy consumption. Valmet uses nozzles with a higher heat transfer coefficient to take more energy from the impingement air. This results in less energy losses to the exhaust air and an increase in the amount of energy transferred to the sheet. Both features increase the dryer’s energy efficiency. 

With a well-functioning sizing section, you make sure that the paper has increased strength and stiffness, prevention of dusting and reduces absorption of ink/coating colour. Coupled with a proporly working coating section you will add good printability and surface properties to the product.

We are market leaders in sizing and coating and can offer different solutions and products to upgrade your equipment. Everything from film applicator beam upgrade, safety upgrades, nip load control, automation solutions, coating beams to web break improvements, consumables and vibration dampers.

The purpose of the coating drying audit is to clarify operation parameters of your dryers, reduce and optimize energy consumption and improve efficiency of the drying process. A Valmet expert will measure and clarify the operational values and check the mechanical conditions. This will enable optimum function of dryers. The report will contain energy saving potential with prioritized recommendations and create a solid base for future actions and investments.
