Fuchs Umwelttechnik INRVA type extraction and filtering device with DEKRA-tested fire and explosion protection concept
By order of a large automobile supplier, DEKRA EXAM, specialist department for explosion protection, tested a fire and explosion concept from Fuchs Umwelttechnik which is designed for the extraction and filtering of emissions produced in the laser welding of stainless steel.
The results revealed that the INRVA type extraction and filtering device from Fuchs Umwelttechnik is equipped with all the auxiliary components and control functions for effectively preventing exothermal reaction to emissions from this process.
DEKRA especially points out that targeted inerting of the welding dust with a high percentage of an inert solid must be performed to prevent the formation of an explosive dust/air mixture. The integration of a CO2 extinguisher which limits possible damage to the filters in the event of a fault in the inerting process is also recommended.
Since the INRVA extraction and filtering device complies exactly with the recommendations of DEKRA EXAM in equipment and design, several devices of this type are already being used by the said automobile supplier.
Fuchs Umwelttechnik offers this extraction concept in different sizes with air volumes of 300 m³ to 2400 m³. An individual project planning and support is ensured by qualified development engineers.
The conversion unit was developed at the request of a customer who is already equipped with numerous TKFVA devices. For their sensor production, they required additional safety measures against the reactive dusts of CrNi steels and titanium. Since the INRVABE3.1 powdering module is designed exclusively for the higher emission quantities of the MKFVA and INRV device types, the consequence would be an expensive total replacement of the extraction and filtering units. Economically, this is no option and not at all what we have in mind.
To meet our customers' requirements, our engineers therefore designed the TKFVAÜG6 conversion unit especially for the appropriate performance data of the most compact device series with automatic filter cleaning TKFVA. With this, the INRVABE3.1 powdering module can now also be used for smaller emission quantities.
Sophisticated in every detail:
- Constant discharge through a chute into a 20-litre barrel by optimum positioning to the TKFVA, even during operation
- The powdering has been parametrised exactly for the smaller emission quantities
- A pinch valve is no longer required for the activation
- PE-film in the barrel for contamination-free disposal
- Barrel emptying by a quick clamp offline
With the new TKFVAÜG6 conversion unit, our customers now have a complete safety solution especially for smaller emission quantities at their disposal which can easily be integrated into existing systems.
Great interest in the TKFVA300 and cyclone pre-separator
The Pantron/Fuchs Umwelttechnik fair booth was a magnet for the professional visitors. Special focus was placed on our latest new developments: the compact TKFVA300 extraction and filtering unit and the cyclone pre-separator. Both systems were convincing in their technical design, their high quality, and their practical possibilities for use in many different industrial applications.
Many concrete customer inquiries from the region
Numerous companies in North and South Carolina took the opportunity to find out about tailor-made extraction and filtering solutions for their specific applications with concrete inquiries on site. Further appointments to visit the companies were arranged during the fair – a clear indication of the great interest in the performance capabilities of our extraction and filtering systems.
Outlook for the Southtec 2027
Following this successful fair appearance, Pantron and Fuchs Umwelttechnik would like to thank all visitors for their keen interest. The joint team is already looking forward to the Southtec 2027.
With this partnership, we are strengthening our local market presence and ensuring that our customers in Switzerland benefit from competent technical know-how, direct customer contact and top-class service.
The Fuchs Aadorf company stands for quality, reliability and technical expertise – ideal conditions for the optimally communicating the advantages and performance capabilities of our devices.
