VIB SteamTech TC

Tissue Curved Steamshower

Mills manufacturing high-quality tissue require a consistent sheet moisture profile on the yankee dryers for even drying. Today, superior performance can be achieved in the moisture profile using VIB SteamTech and its unique actuator technology. The VIB SteamTech TC, a member of the VIB SteamTech Family, is a curved-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 tissue makers.

VIB SteamTech TC 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 machine's productivity and runability. With a VIB SteamTech TC on the suction roll, 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 high speed steam jets onto the web in two separate machine direction zones.

VIB SteamTech TC 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.

Primary material for VIB SteamTech TC is 1.4571 (316 Ti) stainless steel. Special 1.4539 (904 L) grade stainless steel is used for areas subject to 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 easy cleaning and dust removal.
