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.
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.
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.
Heat recovery solutions: Lower energy consumption and higher productivity
TM Systems is very aware of the energy challenges and the pressure toward environment-friendly operations in different process industries. Therefore we have put extra effort to further develop energy saving solutions, including top of the line heat recovery systems. We deliver solutions that cut energy costs and enable more environmentally friendly production.

Mondi Stambolijski Trim Handling: More efficiency needed, but no time for shut-down
Case: Mondi Stambolijski Bulgaria: Trim handling system for a winder.
Goals
The customer’s trim conveying system was not efficient enough. The existing system was ejector-based. The winder was not able to run at full speed and the ejector air was blown to the pulper causing the area to become overpressurised. Additionally, the energy consumption was too high. [Read more…]
Ilim Group Bratsk Heat Recovery: Less energy loss in Siberian conditions
Goals

”We see clear energy savings”, says Pasi Lampinen, Stora Enso Imatra mills
Case: Stora Enso’s Imatra mills at Kaukopää wanted to improve the machine hall ventilation around the PK6 paper machine.
Goals
The investment aimed to improve the machine hall ventilation, to even out the temperature differences and to increase the performance of heat recovery in the ventilation. The goal was also to create savings in energy usage by decreasing the steam usage in supply air heating.
