Reduce energy and CO2 emissions in tissue making

Improve machine efficiency while reducing energy and emissions

The need to reduce energy consumption and to endorse environmental protection pushes Valmet to commit towards the direction of emission reduction. Valmet Advantage ReDry is a product designed exactly with this aim: exploit the hood exhaust air, still rich in energy, which is only partly recovered. This use improves the machine general efficiency, while reducing emissions into the atmosphere. 

Enhance press dryness

With the Advantage ReDry the web temperature increases before the press; as a consequence, the paper dryness level before the hood is increased too. A part of the hot air rich in humidity is diverted from the hood exhaust and blown evenly onto the web, increasing its temperature. This heating effect reduces water viscosity on the web just before it enters the press and produces an improvement in the press performance, raising the dryness level after the press. Energy demand to reach the final dryness is substantially reduced.

Energy savings are obtained from a potential source already there (the hood exhaust), while protecting the environment without jeopardising the workplace.

Explore how it works

This video demonstrate how the Advantage ReDry works and is positioned in the tissue machine. It can be easily positioned just before the suction press or at the turning roll before the shoe press or Advantage ViscoNip press.

In the example in the video it is used with the Advantage Visconip Press.
