OptiDry Twin impingement dryer represent high technology drying, enabling up to 30 % fewer drying cylinders (and thus a shorter paper machine and machine room) and optimized runnability due to higher dry content before cylinder drying. It also provides tools for increasing sheet bulk.

Excellent runnability

Improved quality

More drying capacity

Excellent runnability

  • higher dry content before cylinder drying
  • completely supported web
  • machine line efficiency increases when less breaks

Improved quality

  • gives possibility to increase bulk and save raw material costs
  • draw control optimization

More drying capacity

  • shorter machine and machine room
