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.
Less maintenance costs
Better paper quality
High drying capacity
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 80% and respectively the energy efficiency of infrared dryers only from 25 to 35%. 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 air dryer is suitable for positions where there earlier have been only IR dryers. We have several running paper and board machine references to support this statement. Start saving your energy costs with OptiDry air drying family and PowerFloat nozzles.

Replacing gas with electricity
Many paper producers are looking for ways to eliminate the use of fossil fuels in their production. How can this be achieved in coating drying?
CO2-free coating drying is enabled by using electric heating. A gas burner can be replaced with an electric heater, which can save energy at the same time. When electric heating replaces a gas burner in an air dryer and the process is optimized, energy savings are typically 10–20 percent.
