ACTEGA Coatings & Sealants

Drying

Key parameters in oven design:

  • Circulation of hot air between the ends
  • Continuous renovation of air inside the oven
  • Gradual increase of temperature to avoid blistering
  • Reduced energy consumption & low maintenance cost


HEAT HAS TO BE PROPERLY APPLIED NOT ONLY TO REMOVE WATER BUT ALSO TO ACCELERATE FILM RETICULATION

Evolution of drying scenarios: Traditional

  • Horizontal oven with stacked ends transportation


Actual

  • Vertical oven with individual transportation of ends trought:

    • Screw (risk of coating scratches and end jams)
    • Chain/ pocket


Trend

  • Post heaters with sufficient drying efficiency

    • Low investment cost
    • Low maintenance cost & time
    • Easy change of end diameter
