Vacuum conveyors for explosive and inert gas environments
Handling and transferring bulk materials in hazardous areas, such as chemical and pharmaceutical industries, requires systems that prevent ignition and maintain safety. Challenges include managing powder transfers in gas explosion zones and ensuring inert gas atmospheres.
Ensure safe powder transfer in hazardous environments
The Volkmann INEX Vacuum Conveyors offer secure bulk material handling in hazardous areas by utilizing inert gas systems. Initially, material is sucked into a separator. Once the transportation line is closed, the system is set under vacuum. Inert gas (e.g., Nitrogen) then aerates the material from the bottom, reducing Oxygen concentration below 7%, ensuring safe discharge. The system operates without electricity, preventing ignition sources, and features a fully conductive design, low transportation speeds, no heat, and no rotary parts. It meets ATEX Directive 94/9/EG standards, making it ideal for gas and dust explosion zones, including zones requiring explosion-protection certificates like TÜV 03 ATEX 7017 X.
