Moisture Profiling

Infrared profiling technology enables real-time cross-direction moisture control to improve flatness, reducing curl and mottling, and increasing reel and calender quality.

Quality control (MD) and moisture profiling (CD) for sheet consistency.

The high flexibility of our infrared solutions allows an optimal quality control.

In machine direction (MD), it is possible to adjust the power per each pair of rows, in order to adjust the drying to the specific production requirements.

For Grades with Mottling Tendencies

For grades with mottling tendencies, the power can be focused in the beginning of the drying arch for optimal fixation of the coating layer immediately after the coating head. For other grades, the energy can be distributed along the infrared dryer for gentle drying with optimal efficiency. In configurations after double side coating application, the energy can be distributed differently on each side of the web, to adjust the drying on each side to the corresponding coating application or to adjust the curl tendencies of the web.

Cross Direction

In Cross Direction (CD), our profiling solutions provide accurate and continuous moisture CD control in order to improve paper quality and machine runnability. We have designed our system to include optimal cross-directional profile control. The moisture profile can be corrected in zones of 37,5 – 75 or 150 mm with our electrical IR solution (DryMaster™).

The picture shows an example of improvement of CD moisture without and with CD moisture control. 2-Sigma is reduced by 65 % in this example.

Our Gas-Based Solutions

Our gas-based solutions can also include moisture profiling capabilities in zones of 143 mm, which is very cost-effective for coarse profiling corrections as the solution can easily be integrated inside the main dryer for a small additional cost.

Our profiling systems are installed on all possible paper grades, ranging from tissue to heavy board applications and in different positions including in coating stations, after metering size press or in cylinder drying sections.

For specific wet edges, we supply the electrical EdgeMaster™ which allows drying of edges allowing often to increase the machine speed as the bottleneck is removed.

Coat Drying

Our coat drying systems ensure fast, contactless drying to stabilize coatings, avoid defects, and preserve print quality across all coated paper and board grades.

Size Press Drying

Our size press drying solutions remove surface moisture quickly and gently, helping restore sheet strength, prevent web breaks, and boost production speed.

Barrier Coatings

Our systems deliver rapid, controlled drying of barrier and specialty coatings to eliminate blistering, protect layer integrity, and ensure high-performance end results.

Boost of Production Capacity

Targeted drying upgrades help eliminate bottlenecks, increase evaporation, and boost line speed and capacity – without compromising quality or needing full rebuilds.

Edge Drying

Infrared edge drying stabilises sheet edges during high-speed runs, helping to prevent edge cracks, improve web handling, and increase the overall production capacity.

Energy Savings

We work actively to optimize energy use through emitter upgrades, dryer replacements, ERS systems and more – cutting consumption without compromising quality.
