Process Ventilation

Wet end exhaust: Reduce the humidity and heat load

The wet-end of the paper machine produces most of the heat and moist air leaks into the machine hall. Thus the wet-end exhaust plays a key role as far as the machine hall air flow dimensioning is considered.

 

Product

TM Systems wet-end ventilation system is based on knowledge of different paper machine wet-end configurations as well as on theoretical calculations of evaporation and air movements around moving fabrics.

 

How it works

Our ventilation system evacuates water vapour evaporated at the forming section. This guarantees good working conditions and protects the machine hall from deterioration and corrosion. The exhaust air unit can be silenced to meet the most stringent noise emission regulations.

TM Systems has designed and delivered wire section exhaust air systems that are suitable for many different types of paper and board machines.

 

Benefits

 

Dryer section hoods: Controlling evaporated vapour

 A high dewpoint closed dryer section hood is an essential part of a modern paper machine, but it can also greatly improve the dryer section efficiency of older paper machines.

 

Product

TM Systems offers closed high dewpoint hoods and open canopy hoods. The basic dryer section hood design can easily be adapted to fit all machine configurations. Colours and visual design features can be changed according to your choice.

 

How it works

A dryer section hood collects the water which is evaporated during web drying so that the energy can be recovered and prevents heat and humidity from spreading into the machine hall. These hoods are suitable for all kinds of paper and board machines.

 

Benefits

 

Dryer section air systems: Quality is in the air

The dryer section air systems consist of many important components that affect paper quality, productivity and paper machine runnability. Therefore, the highest possible knowledge of – and experience in – paper drying theory and paper machine technology is essential. TM Systems possesses both.

 

Product

TM Systems supplies all necessary components to ventilate the dryer section: Exhaust air systems, supply air systems, air distribution devices such as pocket ventilators and blowstocks. The benefits achieved by utilizing our Vacubox® web stabilizers and pocket ventilators are increased production, better runnability and paper quality as well as increased paper machine efficiency.

 

How it works 

Our ventilation system evacuates water vapour evaporated during the web drying and supplies dry air to the dryer section in a correct way. Thus, it increases the drying capacity and reduces the required steam pressure. 

Our ventilation systems are suitable for all kinds of paper machines.
