Board and paperProcess ventilation
Valmet’s family of paper machine ventilation processes and products goes under one name – OptiAir. The OptiAir family is a complete energy-efficient set-up for paper and board machine process ventilation. The family consists of the OptiAir Hood, OptiAir Recovery and OptiAir Environment processes and products.
Board and paperMetal belt technology
Pressing with metal belt technology boosts production capacity by eliminating unsupported open draws. It also increases the dry content after the press by up to 6 % due to more effective water removal at the press nip and evaporation over the hot metal belt. Furthermore, it improves several end product qualities, such as strength and porosity.
Board and paperImprove quality
Quality issues are high on the agenda of every paper and board mill, as optimal quality needs to be produced at the lowest possible cost. Valmet offers a wide scope of solutions and services for better end-product quality, from stock preparation to finishing. Stabilizing running processes in all phases of the process leads to cost-effective quality improvements that do not require major investments. We and our customers share the same targets: optimal quality at the lowest possible cost, consistently in all shifts.
Board and paperCylinder drying
In papermaking, it is vital to ensure maximum drying efficiency with minimum energy consumption. Valmet cylinder drying portfolio is able to provide perfect solutions for all customer needs regardless of your grade, machine speed, or basis weight. Our offering also includes rebuilds, components, and services, in addition to various drying analyses and optimization services.
Board and paperOptiFlo Gap headbox
The key elements of the OptiFlo Gap headbox are its redesigned headbox turbulence generator and slice channel. These allow a consistent and disturbance-free slice jet. The objective of the OptiFlo Gap headbox is to achieve optimal fiber suspension fluidization and to maintain optimal fluidization without disturbance across the forming section.
Board and paperHigh efficiency drying
OptiDry Twin impingement dryer represent high technology drying, enabling up to 30 % fewer drying cylinders (and thus a shorter paper machine and machine room) and optimized runnability due to higher dry content before cylinder drying. It also provides tools for increasing sheet bulk.
Board and paperIncrease capacity
There are several ways to increase the production of a paper or board making line. The paper machine's efficiency can be improved for example by decreasing the number of breaks and shortening the break time. Drying capacity can be found to be a bottleneck. Drying capacity can be increased by solutions that maximize drying efficiency with minimum energy consumption. Machine speed can be limiting production, too.
