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.
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.
It’s all about stability and contact. Dryer sections are often single felted in order to improve paper machine runnability at higher speeds. The paper tends to lift off the dryer fabric mainly at the closing nips. This causes wrinkles and web breaks, as well as other problems. Our Vacubox® web stabilizers keep the paper in good contact with the fabric thus preventing web flutter and instability. [Read more…]
Case: A Trimvac® trim handling system for a new converting plant in Setubal Portugal.
Case: Mondi Syktyvkar, Russia. HVAC for Pulp Dryer Building.
To improve the machine room ventilation in the pulp dryer building and in the control room. To prevent condensation on the inner roof especially during cold winter months with temperatures lower than -35˚C.
Case: Mondi Stambolijski Bulgaria: Trim handling system for a winder.
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…]

Asia Pulp and Paper APP set particularly high standards for the ventilation system of the world’s largest pulp and paper mill, OKI, to be built in Indonesia. They were met by TM Systems’ HVAC system. TM Systems is one of the key suppliers in this massive project. [Read more…]
Case: Stora Enso’s Imatra mills at Kaukopää wanted to improve the machine hall ventilation around the PK6 paper machine.
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.
