Development Focus
� Main application- Paper production at high energy cost
� Paper machines- Fourdrinier, Hybrid-Former and Gap-Former
� Operational targets- Decrease of energy consumption- Speed increase, but max drive load is reached

Trial PET/PA and E-Line 2. Case study
Customer focus: Maximum production outputLimitation: Close to maximum drive load
PM setup�Consistency increase�Vacuum decrease
PM setup�Normal Consistency�Maximum vacuum
Added Value:�Good paper quality�Less chemicals(mainly starch) demand
�Good runability�Drive load decrease of 150 kW
Undesirable effects:�Decrease on paper quality�High chemicals(mainly starch) demand
�Worse runability
