AirTechClassic

Fine Droplets Spray System

Paper and board mills manufacturing quality paper require a consistent sheet moisture profile along the entire length of the paper production line. Today, superior performance can be achieved in the moisture profile using VIB SprayTech and its unique air water spray technology with PSM (particle size management). The VIB AirTechClassic a member of the SprayTechฎ family, is the industry standard for spraydampening system. The proprietary fine droplets nozzle technology allows VIB Systems to provide an application-matched solution. These high-performance spray nozzles provide papermakers with the industry's narrowest control zone width (down to 25 mm).

VIB AirTechClassic Description
The most important characteristics of a fine droplet spraydampening system are its profiling capability and its ability to control the average moisture level. These two characteristics improve the sheet's cross-directional moisture profile and optimize the paper machine's productivity and runability. Controlling to a flat moisture profile with a high average moisture target is possible using a VIB AirTechClassic in the drying section.

The critical proprietary components of the system are the patented VIB two-stage nozzles that create a balanced and application-matched mixture of air and water. The water nozzles are located in the center of the air nozzles. Directional vanes integrated into the nozzle create a rotational air flow from the nozzle.

The rotating air pulls the water from the nozzle and transforms it into a highly atomized, full cone spray pattern that is efficiently applied to the web. The fine droplet size increases the absorption into the web and allows application closer to the dry end of the process. The dry end application reduces the dryer load and results in reduced steam consumption. This eliminates the compromise between production increases and profiling capability.
