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.
Valmet´s famous air dryers PowerDry and TurnDry are now available under the renewed OptiDry air drying family.
World’s best paper machine: UWF speed record 1,808 m/min - Zhanjiang Chenming PM 1
The Zhanjiang Chenming PM1 in China has been setting world speed records since it's start-up in 2011. Considering energy and raw material consumption / produced tonne it is also an economical and ecological paper machine.
