High efficiency drying

Revolutionary technology for high efficiency drying

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, and it also provides tools for increasing sheet bulk.

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
  • efficient drying
  • makes it possible to use higher steam pressures from the beginning of the dryer section

OptiDry Twin has proved it's efficiency in several references. One of those being Zhanjiang Chenming PM 1 with UWF speed record of 1,808 m/min.
