EVst ventilator

improves evaporation capacity and runnability in single felted drying sections

Sheet separation from the top dryer cylinder creates underpressure in the opening nip causing sheet detachment and flutter.

EVst Ventilator blows warm and dry hood supply air to the area below the dryer groups. EVst Ventilator decreases the pocket humidity level and it is effective for equalizing moisture distribution across the entire width of wet paper and therefore economizing steam consumption. This means more efficient production and lower drying costs.
