Pulp and Paper Ventilation Technology 

PAPER MACHINE VENTILATION

Large amounts of moisture from the pulp evaporates during the manufacturing process, in particular from the Wire Section and the Press Section as illustrated below.  This steam is corrosive and therefore destructive to all surfaces on which it condensates, including concrete constructions, steel reinforcements and plant and machinery surfaces in general.

With the life expectancy significantly reduced through corrosion, the plant and buildings must be repaired or replaced very frequently.  This adds to the operating cost of the factory and reduces the overall competitiveness of the company owning the factory.

The humidity and temperature in the space surrounding these processes are high.  The vapors create an uncomfortable and unhealthy working environment, and this reduces the productivity which further adds to the paper production cost.    

THE SOLUTION

During the pulping and papermaking process large amounts of excess heat and corrosive vapour must be removed, normally with paper machine drying hoods and other dryer systems.  

Gupex manufacture effective air flow control systems and industrial ventilation with optimum energy recovery-to-waste ratio.

Our simple, yet highly effective and, of course, corrosion resistant and maintenance free systems ensures that the heat and evaporation from the production line only goes where you want it to go.  

Also, all condensation problems are eliminated.  This not only preserves your buildings but it also stops condensation on the roof surfaces and therefore eliminates dripping onto the production line.  Wider access to the production line can easily be made available within a short time.  

Finally, with the removal of the humid, hot and acidic vapors from the space around the production line the working environment is improved dramatically.
