DRYTEC ROLLER DRYERS – especially suitable for web tension sensitive materials

The roller and material speed is 100% synchronised thanks to our outstanding drive solutions. Hot air can be applied to the material web from above as well as from below and above.

Description

The ROLLTEC/CONTEC roller dryers – fast and energy-efficient

The DRYTEC roller dryers feature a sophisticated drying technology for thick coatings and for coatings that tend to form a skin

  • The substrate web is optionally guided through the dryer via driven or non-driven guide rollers
  • All rollers are equipped with "low friction" bearings
  • Production speeds up to 1,000 m/min are possible
  • The recirculation air volume flows can be adjusted steplessly according to the required drying processes
  • The recirculation air is filtered according to the product requirements
  • Efficient energy input from below is possible thanks to special CONTEC nozzle systems.
  • CONTEC nozzle systems allow higher air volumes on the underside of the substrate without lifting off the web
  • Depending on the requirements, the installation can be carried out horizontally, vertically or also as an arc
  • Tangential air guidance through switch-over/impingement jet/floating nozzles for particularly gentle drying
  • DUOTEC version with separate temperature and air conduction above and below the substrate
