 The VIB SteamTech profiler being lowered by crane, and connected to the retraction unit and the utility pipes.
Control Station ECS is a VIB SteamTech electronic control station that governs the pneumatic actuators. Each actuator is controlled by an I/P-converter with a control signal of 0.8 - 4 bar (12 - 60 psi). Setpoints are sent from the VIB Control Station IPS using measurement system data.
Control Station IPS is an integrated process station that 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.
- Optional feedback of the actuator position ensures reliable functioning of the VIB SteamTech Actuator.
- Better creping owing to an even moisture profile.
- CD moisture 2-sigma improvement of 60%, profile correction of 2.5%.
- Dryness increase of 3 - 4% downstream of the suction press roll.
- 8 - 12% higher output.
- Improved runability on the whole production line.
- Improved converting owing to better moisture profiles.
- 1.5 - 3% increase in efficiency of the total production line with integrated moisture control.
