Explosion-free Pneumatic Conveying

October 17, 2013

Volkmann INEX conveyorVolkmann offers INEX (inert explosion proof) equipment using nitrogen as the conveying gas for Zone 1 (Class I) applications where fumes are present. Volkmann INEX reactor loaders safely convey dry or wet powder and granules into hazardous/explosion risk areas. By using a sophisticated, patent-pending nitrogen purging function, INEX reduces oxygen content within the unloaded batch to below 7% (or lower when required), maintaining the material’s inert safety while providing dust-free transport. The INEX features a closed station which can be flushed from within by drawing in the washing liquid or through WIP/CIP. Standard lightweight and pressure-rated systems are available with INEX functionality.
