On-line air dryers

Air vector is employed in drying process every time the characteristics of a sheet require gentle treatment and forbid mechanical contact. Non-contact drying solutions offer significant advantages in terms of:

  • Homogeneity of drying both in MD and CD, thanks to uniform heat transfer (homogenous temperature and velocity)
  • Fine tuning of drying according to maximal evaporating rate sustainable by the end-product
  • Ability to limit infiltration of layer treatment inside the web, particularly appreciated as it saves pigments, starch etc.
  • Possibility to increase existing speed of the machine without increasing its length
  • Maximal drying capacity with minimum space requirement compared to traditional drying solutions
  • Maximal machine performances while maintaining product quality and machine efficiency
  • Energy care, efficiency of air drying may reach 80%, even more, compared to 70% only in classic can dryers sections

Special features

  • AirTurn dryer,  the economical ‘’two-in-one’’ configuration after sizer, alternative to infrared
  • U-Turn dryer, simplifying and compacting at the most the coating machines, also installed under dryer section wherever the space is strictly limited while speed-up expected
  • Turbo Aircaps, to boost machine speed and/or substituted to can dryers
  • Airfoil dryer, single or double side open clamshell, lift or slide, cantilever
  • InfraAir, the other ‘’two-in-one’’ solution incorporating infrared emitters everywhere maximal evaporation is desired in minimal space while quality and efficiency are preserved
  • Impingement dryer, single or double side, sheet supported on rolls or conveyor wire
  • Reticulation/polymerization drying tunnels   
  • Through-Air Dryer (TAD), on tumbler or flat conveyor, used for drying porous or fragile products
  • Stream dryers, dedicated to powdery or fibrous products treatment
  • Fumes heating (gas turbines, boilers, power plants, incinerators…)
  • Heat recovery system, designed according to your own requirements
  • Fire detection and steam extinguishing system
