Effective non-contact paper web cooling
OptiDry Chill web cooling
OptiDry Chill web coolers offer excellent runnability and high cooling capacity due to their efficient nozzle technology. Maintenance costs are low because of the few wearing parts.
Optimized runnability
Effective cooling with proven PowerFloat nozzle technology
Warm return air exhausted out of machine hall
Excellent control of air flows
Excessively high paper web temperatures often cause problems when the paper enters the coater. These problems affect the coating process and the quality of the finished product. Valmet's web coolers offer solutions to such problems.
Double-pass cooling calendering
OptiDry Chill air cooling units are used in bulk-saving calendering technology called double-pass cooling calendering. The sizes of the cooling units are very compact and the web passes the units twice.
Main benefits of double-pass cooling
- Double-pass cooler with integrated air turn section has a long cooling section with a compact design
- Efficient PowerFloat Plus nozzle technology offers excellent web runnability and cooling efficiency
