OptiPress Center
Center roll based press section is a reliable, well-known concept combining close to 40 years of pressing technology experience with modern shoe press technology. A shoe press replaces a roll just before the first open draw. The resulting boost in dryness thus fully benefits web runnability in the open draw.

Runnability Systems
Runnability systems stabilize the run of the web and secure tail threading in the dryer section. In practice, the equipment helps to hold the web in contact with the fabric by creating underpressure on the other side of the fabric. The underpressure is created by blowing, suction, or a combination of both.

IntelliPress TriNip
IntelliPress TriNip is a compact concept for lighter grades with one side web smoothness. Optimal pressing minimizes drying energy. The Valmet IntelliPress TriNip consists of three presses combined into a compact design. The first nip is double felted and controls bulk. The second nip is single felted and controls dewatering and provides an easy transfer to the center roll surface. The third nip is equipped with the IntelliNip Shoe Module generating the contact pressure and an optimized residence time in the nip area. It provides high press dryness with low drying energy consumption and reduced CO2 emissions. This kind of pressing is suited to recycled containerboard production with lighter basis weights. The IntelliPress TriNip technology positively impacts the smoothness of the bottom side of the paper. The surface quality produced is sufficient for printing and creates an economical containerboard product.
