Paper and board mills manufacturing high-quality paper require a consistent sheet moisture profile along the entire length of the machine. Today, superior performance can be achieved in the moisture profile using VIB SteamTech and its unique steamshower technology. The VIB SteamTechFF (Fourdrinier flat), a member of the VIB SteamTech Family, is a multi-section steam shower system for the forming section. Our advanced technology enables VIB Systems to provide a reliable, high-performance steam actuator with zone spacing down to 50 mm. This, coupled with our durable pneumatic actuators, provides superior benefits for today's papermakers.

VIB SteamTechFF Description
The most important characteristics of a good Fourdrinier steamshower are its profiling capability and its ability to raise dry content in the first press. These two characteristics improve the sheet's cross-directional moisture profile and optimize the paper machine's productivity and runability. A VIB SteamTechFF in the forming section makes it possible to control the moisture profile and average moisture level.
Increasing the velocity of the steam jets onto the web eliminates the compromise between production increases and profiling capability. The VIB SteamTech FF has two steam sealing zones to keep steam under the box, providing maximum benefit with minimum steam leakage.

 Thorough inspection through maintenance and cleaning openings.
VIB SteamTechFF has a unique diffuser plate with varying spacing in the machine direction to make the profiler more efficient. The profiling zone is fully compartmentalized, supplying high-velocity steam to each cross-direction compartment via a separate, uniquely designed actuation valve that allows optimum zone definition and precise control. The proprietary design of the converging nozzles generates higher steam velocity to ensure greater steam condensation and thermal transfer into the paper web.
Primary material for VIB SteamTechFF is 1.4571 (316 Ti) stainless steel. Special-grade stainless steel 1.4539 (904 L) is used to prevent wear from high corrosion at the diffuser plate, edge-heating zones and in pneumatic control lines. An optional Teflon coating is also available for the diffuser plate and edge heating zones for easier cleaning.
