Volkmann’s ATEX-approved INEX vacuum conveying system takes vacuum transfer of dry or wet powder and granules into potentially hazardous conditions to a new level. By using a sophisticated, patent-pending nitrogen purging function, INEX reduces oxygen content within the unloaded batch to 7% or less, maintaining the material’s inert safety while providing dust-free transport. The INEX features a closed station that can be flushed from within by sucking in the washing liquid or through WIP/CIP. Standard lightweight and pressure-rated systems are available with INEX functionality. Volkmann systems are able to provide effective and reliable transport due to their multiple-stage Venturi Multijector® vacuum pump which allows dense-phase transportation under vacuum without segregation, damage or abrasion. All Volkmann vacuum conveying systems can be used for dust-explosion zones. Systems can be stationary or mobile depending on the application, and PTFE/EFTE coated vacuum conveyors are available for improved chemical resistance.
