Vacuum Conveyors with Inerting function: Volkmann INEX. Volkmann INEX Vacuum Conveyors provide safe loading of bulk materials into hazardous areas, particular in the Chemical and Pharma Industries, where the loading of powders into reactors and stirring vessels is required. INEX systems can be used inside all gas explosion and dust explosion zones.
Initially material is sucked into the separator of the INEX system. Before the material is discharged, the transportation line is closed and the INEX system is set under vacuum. Then, the material inside the INEX system is aerated with inert gas (for example Nitrogen) from the bottom and then released through the systems discharge valve. The concentration of Oxygen during discharge typically is below 7% or limited to such a value to not compromise the inert feed of the system.
For the conveying of hybrid mixtures, where the transfer of powders containing solvents, the entire vacuum transportation process with an INEX Vacuum Conveying system takes place under inert atmosphere.
