OptiDry Coat air dryers

Innovative, energy efficient air dryers for paper and board making

OptiDry Coat air dryers are designed for high drying capacity. Aided by patented air dryer nozzles, the dryers achieve uniform evaporation with minimum energy consumption, high efficiency and excellent runnability. We can prove you get the best paper quality and lowest energy consumption with Valmet air dryers.

Coating drying is very energy demanding process and with air dryers it is possible to cut to half the energy costs of it. The energy efficiency of Valmet air dryers ranges from 70 to 90 % and respectively the energy efficiency of infrared dryers only from 30 to 40 %. So energy savings with air drying are 50 % or more compared to infrared drying. The OptiDry Coat air dryers are high efficiency coating dryers for all coated paper and board grades. They can be used for both, new machines and rebuilds.

There are basically two kind of OptiDry Coat air dryers with several applications:

  • OptiDry Coat high intensity, energy efficient air dryer for replacing IR dryers.
  • OptiDry Coat air dryers for all the coating drying. Several applications with heating and layout.

Drying with OptiDry air dryers gives excellent:

  • energy efficiency
  • drying capacity
  • end product quality
  • runnability along with
  • easy and low cost maintenance
  • better working environment
  • less fire hazard
  • environmentally friendly approach
