Valmet OptiAir - a complete paper machine process ventilation in one package

Drying is the most energy intensive process of the paper machine and it can consume more than 80 % of the total thermal energy. A well-functioning hood, runnability system and heat recovery with air systems play a crucial role in energy efficiency and provide excellent opportunities for reducing costs and increasing the profitability. Valmet’s OptiAir family is designed for optimal and controlled drying conditions and working environment for paper and board machines.
