Process upgrades for board and paper machines

Process upgrades

Improve the production performance of board and paper machines with process upgrades

How to raise the production efficiency or quality to the new level and at the same time lower the maintenance costs?

Process upgrades are small or mid-size investments that opens up production bottlenecks or extends the original process design limitations. Typical process upgrade building blocks are design engineering, new components, new machine and process controls and efficient commissioning and start-up service
