Vakuum-Conveyors with Inerting-Function:
Volkmann Inert-Conveyors INEX

Our Vacuum Conveyors INEX with Inerting function are based on the Vacuum Conveyor families VR and PPC. They transfer materials under inert conditions into all sorts of process machinery. Optional the whole conveying process itself can be done under Nitrogen or other inert gases. INEX Vacuum Conveyors are the reliable solution for transferring easily inflammable bulk materials, for the filling of reactors under atmospheric conditions, which have burnable liquids of gases inside.

In the first step, the product is conveyed under air or inert gas into the separator container of the vacuum conveyor. After filling of the separating container the conveyors product inlet is closed and the product inside the conveyor is set under vacuum (-50 to -90 kPa, depending on the application). Subsequently, the pressure inside the separator is balanced with inert gas. This inerting can be done several (usually 3) times, to ensure a high level of Oxygen reduction.

Then the material is released from the conveyor through its bottom discharge valve. Since ignitable gases may move upwards into the conveyor during its discharge through the discharge valve, a new inerting cycle is run to bring the interior of the conveyor back into inert conditions before the next material suction cycle.

INEX Vacuum Conveyors are highly interesting for the filling of reactors, if the solids can be brought into the vessels under atmospheric pressure conditions. If a positive pressure in the unit to be fed occurs during the following process, the INEX conveyor is disconnected by a pressure resistant valve (if necessary with safety monitoring and pressure relief). INEX vacuum conveyors have all the advantages of VR- and PPC Conveyors. They are lightweight, easy to assemble and disassemble, have superior material qualities and can be used in FDA applications. They are much easier in operation than pressure-proof vacuum conveyors and come with really working filter units with big filtration area.
