VIB SteamTech TFF

Teflon Flat Felt Heating Steamshower

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 actuator technology. The VIB SteamTech TFF, a member of the VIB SteamTech Family, is a flat-type steam actuator system for the press 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 SteamTech TFF Description
The most important characteristics of a good steam actuator are its profiling capability and its ability to raise dry content. These two characteristics improve the sheet's cross-directional moisture profile and optimize the paper machine's productivity and runability. With a VIB SteamTech TFF in the press section, managing the moisture profile and drying capacity becomes considerably easier.

The compromise between production increases and profiling capability has been eliminated by increasing the velocity of the steam jets onto the web in two separate machine direction zones.

VIB SteamTech TFF has two zones 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 constant full-width zone has higher steam velocity to ensure greater steam condensation on the paper web.

An additional boosting effect is created with a felt heating zone which increases the surface temperature of the felt to prevent heat losses when felt and paper are in contact.
