Multi-cylinder pre-dryer section for controlled moisture removal before sizing.
Multi-cylinder pre-dryer section for controlled moisture removal before sizing.
The pre-dryer section performs the critical function of reducing sheet moisture from press section exit levels to the target moisture before size press application. Parason's pre-dryer sections combine proven thermal engineering principles with modern frame designs that optimize heat transfer while minimizing energy consumption.
Our pre-dryer configurations feature flexible frame options—L-shaped and Y-shaped designs—that accommodate various machine layouts and building constraints while ensuring optimal sheet threading and accessibility for maintenance.
The choice of dryer cylinder type—cast iron or steel—enables optimization based on speed requirements, energy considerations, and capital budget, with steel dryers offering enhanced heat transfer for high-speed applications.
