STIF Combines Conveying Components with Active Explosion Protection

STIF is a specialized manufacturer of components for explosion protection and bulk material handling industries. Our passive explosion protection range, VIGILEX, includes deflagration vent panels, flameless venting devices, and explosion isolation valves. Follow the links of the photos below to visit the webpage providing detailed information on these solutions. In the bulk material handling segment, our main products include pressed steel and plastic elevator buckets, elevator belts, compression couplings for pneumatic conveying systems, slide valves and diverter valves for grain handling applications, as well as safety valves and inspection manholes. In 2025, STIF acquired STUVEX, expanding our portfolio with solutions focused on active explosion protection, designed to prevent, detect, and mitigate explosions. These solutions include explosion suppression systems, grounding systems, and other advanced safety technologies. To reduce CO₂ emissions and better serve our global customers, STIF operates manufacturing facilities on three continents, with production sites located in France, China, and the United States.

We are proud to announce that VIGIFLAM VI, provided by STIF, has won the GRAPAS Award in this prestigious competition, underlining its contribution to improving safety in dust-handling processes. At this year’s VICTAM International exhibition in Utrecht, one of the leading global events one of the leading global events for the feed, grain and milling industries, innovation once again took center stage. Among the highlights of the exhibition was the GRAPAS Awards, which recognize outstanding technological developments and provides a valuable platform to showcase innovations that drive the industry forward. Addressing a critical safety challenge Dust explosion risk remains a major concern across the grain, feed and bulk solids handling industries. Equipment such as bucket elevators and conveyors are particularly vulnerable due to the concentration and movement of combustible dust. VIGIFLAM VI introduces a new generation of flameless explosion protection, designed specifically to mitigate these risks within indoor industrial environments. It effectively neutralizes flames, burning particles and embers released during an explosion venting event, preventing…

Safety is top priority in environments where the risk of dust explosion is present. STIF addresses this challenge with VIGIFLAM VI, a revolutionary device designed for indoor flameless explosion venting. In industrial environments where the risk of dust explosion is present, ensuring the safety of equipment and operators is a top priority. The company STIF, leader on the market of passive explosion protection technology, addresses this challenge with VIGIFLAM VI, a revolutionary device designed for indoor flameless explosion venting. Risk of Dust Explosion A mixture of air and dust can be explosive under certain conditions. When flammable material is handled in large quantities, the dust level can become so high that there is a risk of explosion. When flammable dust is mixed with air and the dust concentration becomes sufficiently high, the fire in one particle can ignite the other - and then things go wrong. Flameless Explosion Venting Flameless explosion relief enables safe explosion relief in enclosed or indoor areas without the release of flames, sparks, and heat to the surroundings. The system can thus be used for machines and equipment located in areas…

STUVEX, recently acquired by the STIF Group, has developed the Flash explosion suppression system and a chemical barrier. ATEX certified solutions designed to protect critical process equipment in sugar production. A Major Industrial Challenge for the Sugar Industry The sugar industry plays a strategic role worldwide. Sugar production—mainly from sugarcane (nearly 80% of global production) and sugar beets—amounts to more than 140 million tons per year and is concentrated in around a dozen major producing countries. In Europe, the beet sugar sector remains a historical pillar of the agri-food industry, supported by a dense network of sugar factories, storage silos, and packaging plants. This industrial concentration, however, comes with a major and often underestimated risk: the risk of sugar dust explosions. Every process stage—transport, elevation, storage, and filling—can generate clouds of combustible dust, which can lead to serious accidents with grave human, material, and economic consequences. Sugar: A Food Product... Yet Explosive When sugar is dispersed in the air as fine dust, it exhibits all the characteristics of an explosive, combustible material. If it…

The acquisition marks a key strategic step in STIF’s growth, positioning the company as a comprehensive industrial and energy safety provider in Europe and beyond. STIF, a French specialist in passive explosion protection, has completed the acquisition of Belgian company StuvEx, a leading European provider of active explosion protection systems. The acquisition marks a key strategic step in STIF’s growth, positioning the company as a comprehensive industrial and energy safety provider in Europe and beyond. By integrating StuvEx’s expertise in active protection—covering detection, suppression, and isolation systems—STIF now offers a full spectrum of explosion protection technologies. This move enhances its presence across key sectors such as agri-food, chemicals, dust treatment, and wood processing. Headquartered in Belgium with around 50 employees, StuvEx generated €13 million in revenue in 2024 and has demonstrated solid profitability. Its operations are concentrated in the Benelux region, France, and the UK. The acquisition, mainly financed through bank debt, will be consolidated into STIF’s accounts from July 1, 2025.
