AirTechClassic

Fine Droplets Spray System

The VIB AirTechClassic system consists of a sprayboom on which proprietary, two-stage nozzles are mounted; digital hardware station (DHSClassic); air supply unit and water supply unit; integrated process station; operator station; and the necessary system cable and interfaces to communicate with the measurement systems.

Digital Hardware Station Classic (DHSClassic) is an electronic control station that governs the flow through the digital valve blocks. Each valve block has 16 digital steps from zero to maximum flow. Setpoints are sent from the VIB Integrated Process Station (IPSPlus) using measurement system data.

The Integrated Process Station (IPSPlus) serves as the central process point for the system. It contains the integrated MD/CD control, the operator visualization package, PLC functions and the intelligence to control the entire actuator control system.

Benefits for the Paper Industry

  • Higher output and a flatter moisture profile can be achieved simultaneously.
  • Narrow spacing of the actuator can be adjusted to produce the desired profiling effect.
  • Digital flow steps determine the exact flow rate through each digital block and each nozzle for precise and responsive control.
  • Better edge performance for improved reel building.
  • CD moisture 2-sigma improvement of 60%, profile correction of 3% to 5%.
  • Reel average moisture increased by 0.5% - 4.0%.
  • Energy savings produced from a consistent moisture profile and higher average moisture.
  • Improved tension profile and reel building.
  • Higher caliper and a flatter caliper profile.
  • 2 - 3% fewer rejects due to better paper quality.
  • 2 - 4% increase in efficiency of the total production line with integrated moisture control.
