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 requiered. INEX systems can be used inside all gas 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 areated with inert gas (for example Nitrogene) from the bottom and then released through the systems discharge valve. The concentration of Oxigen 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 hybride mixtures, where the transfer of powders containing solvents, the entire vacuum transportation process with an INEX Vacuum Conveying system takes place under inert atmosphere. Volkmann INEX Vacuum Conveyors for hazardous applications and Explosion Zones free of ignition sources operate completely pneumatic without electricity completely electrical conductive design small interior filling volumes low transportation speeds no heat produced no hot surfaces no rotary parts easy to control and to operate. Volkmann provides profound expertise and support for all hazardous applications relying on our experience and knowledge. All systems have been designed for the specific demands of hazardous applications.

Dedusting in difficult filtration processes with adhesive, abrasive or combustible dusts.

INFA-Vario-Jet AJV for dust extraction in the bulk materials industry.

Two-stage cassette filter system for the reliable filtration of toxic dusts during the production of highly active pharmaceutical ingredients. The INFA-MICRON MKR cassette filter system is available as a cassette filter in either a single-stage or two-stage configuration, depending on requirements, and also as a downstream safety filter (police filter) without a cleaning unit. The modular filter series covers an air volume range from &gt; 500 m³/h up to larger volume flows of approximately 20,000 m³/h through the parallel use of multiple filter modules. The two-stage design ensures residual dust levels down to 0.001 mg/m³. Filter media used include class H13 filter cassettes in the first filter stage with a cleaning unit and class H13 to U15 filter cassettes for the second filter stage without a cleaning unit. Requirements for operational safety and freedom from contamination, as well as the consideration of health and environmental aspects during dust extraction, necessitate the special design and manufacturing of these filter units. Risks associated with the filtration of highly active substances (HPPS), hazardous or toxic dusts, and respirable airborne particles are minimized with these units. Key features include: ▫ suitability for laboratory use due to very low cleaning noise at the threshold of perception ▫ minimized system height ▫ leak testing of each individual filter cartridge possible ▫ optimal cleanability externally and in the raw gas area ▫ simple and quick filter cartridge replacement for non-critical dust types and frequent product changes without the use of safe-change technology ▫ for toxic and critical dust types, the containment system with safe-change technology can be additionally used ▫ suitable for almost all ATEX applications

Two-stage cartridge filter system for the reliable filtration of toxic dusts in the production of highly active pharmaceutical ingredients. Application: This two-stage filter system offers high operational reliability for dust removal in demanding manufacturing processes with particulate emissions, such as toxic dusts or powders. The INFA-MICRON MPR cartridge filter was developed for dusts that are not only highly hazardous but also difficult to filtration. The horizontally mounted filter cartridges are cleaned offline using a jet-pulse process and an additional top-level cleaning step. This process extends the range of applications to include more strongly adhering or sticky dusts. The jet-pulse process, with its intensive cleaning pulse, results in thorough cleaning of the filter cartridges. Additionally, the filter cartridges can be pre-coated or operated with a continuous additive injection system. This ensures long-term filter performance with a stable pressure drop. Advantages ▫ High Containment up to OEB4 ▫ Separation efficiency 1st filter stage H13: 99.95% ▫ Separation efficiency 2nd filter stage H14: 99.995% ▫ Residual dust levels down to 0.001 mg/m³ ▫ Raw gas dust loading up to 10 g/m³ ▫ Highly effective jet-pulse cleaning system Special features Jet-pulse cleaning of the filter cartridge ▫ Optimal cleaning enables long service life of the filter material ▫ Optional pre-coating or continuous additive addition for improved cleanability with adhering or sticky dusts
