Static electricity in silos: invisible, but never innocent
Static electricity poses a real explosion risk when filling and emptying silos with dry materials. During this process, electrostatic charges develop through friction. Just one spark is enough to cause a dust explosion. This applies to both metal and composite silos.In sectors such as food, chemicals, and feed – where flammable or explosion-sensitive materials are handled – this risk cannot be ignored.How Polem solves this problemAt Polem, safety is paramount. In collaboration with ISMA (Kontich, Belgium), we developed a certified grounding system, specifically for silos containing explosion-hazardous bulk materials.The advantages of the system:Reliable grounding - Effectively captures static charge and complies with applicable safety standards.Hygienic design - The stainless steel screw plug and open fork connection are easy to clean and prevent dirt accumulation.

Proud of our partnership with ForFarmers during their challenging silo renovation in Deventer!
At the heart of the ForFarmers factory in Deventer, a team faced an extraordinary challenge: replacing a 40-year-old indoor silo in the middle of an operational production process. A complex operation that was not only technically challenging but also required strict safety measures. As a specialist in high-quality composite storage solutions, Polem was proud to be part of this project.The challenge: renovating in a 'high-risk area'The silo that needed renovation was located in the raw materials block, in the middle of the production process. What made this job particularly complex was that the silo was used for the temporary storage of warm and moist 'startup product' - a flammable material with residues remaining in the silo. Moreover, a floor and a roof extension rested on the silo.According to the inspection by a certified mill builder, the 40-year-old silo showed clear signs of wear due to the abrasive action of the product. Additionally, the combination of heat and moisture had caused corrosion formation under the coating.The solution: seamless composite silosAfter careful consideration, ForFarmers decided not to replace the silo walls but opted for a more innovative approach: placing round polyester silos within the framework of the existing square silo. To make this possible, an opening was made in the facade through which the round silo parts could be brought in one by one."The fact that polyester is more resistant to corrosion under the influence of heat and moisture than steel needs no explanation," says Harry Tragter, plant manager at ForFarmers. "But there are more arguments in favor of smaller polyester silos. Instead of one silo, there are now four silos available. This expansion offers great operational advantages. The total storage capacity is somewhat smaller, but the extra silos offer much more flexibility."Safety as top priorityAt ForFarmers, safety is always the top priority. Specific safety measures were taken for this project, including:Thorough cleaning of the silo and silo wallsAvoiding 'hot work activities' such as welding where possibleApplication of water atomization where necessaryOrganization of safety supervision and engagement of a fire watchTemporary production stops during high-risk activitiesRoeland Dinkelman, technical team leader at ForFarmers, emphasizes the importance of these measures: "Various preventive measures and different activities were necessary for the safe execution of the project, including the preparation of safety analyses and safety plans."A successful collaborationThe renovation project was a joint effort by ForFarmers, Peree Bouwadvies, Van Mourik Group, and Polem. Thanks to this collaboration and the expertise of ForFarmers' safety team, the complicated project was successfully completed.Project leader Erik Kuiper of ForFarmers is satisfied with the result: "Valuable experience has been gained with the project, which can be applied again in similar projects within the organization."Why choose composite silos from Polem?The choice for our composite silos in this project illustrates the advantages these solutions offer:Corrosion resistance: Our silos are resistant to aggressive substances, heat, and moistureSeamless construction: No weak spots or risk of leakageLong lifespan: Minimal maintenance for decades of useCustomization possible: Adapted to the specific requirements of your location and processesOperational flexibility: Multiple smaller silos offer more storage flexibilityAt Polem, we continue to innovate and collaborate with partners like ForFarmers to provide safe, sustainable, and efficient storage solutions for the most challenging situations.Interested in what Polem can mean for your storage needs?

Optimal de-icing begins with reliable storage solutions
When temperatures drop below freezing, every minute counts. Road managers who cannot deploy within 30 minutes risk unsafe roads and accidents. Effective de-icing therefore begins not on the road, but at your storage facilities, where spreading salt and brine must be ready for use at all times—regardless of circumstances.The challenges of salt storageSpreading salt and brine are natural enemies of conventional metal storage systems. In practice, we regularly see silos showing severe corrosion damage after just 5-7 years, despite being designed for a lifespan of 15+ years. Even stainless steel cannot withstand the aggressive effects of salt solutions on connection pieces and moving parts. Additionally, condensation in the silo can lead to bridging of the salt, preventing proper flow. This creates operational problems precisely when you need the material most.The solution lies in corrosion-resistant storage systems specifically designed for the challenging properties of de-icing materials.Advantages of composites for salt storageComposite (GRP) offers significant advantages for storing spreading salt and brine:Absolute corrosion resistance: Unlike metal or concrete, salt does not attack the molecular structure of composite—even after decades of intensive useSeamless construction: The smooth, seamless inner wall ensures optimal product dischargeSuperior insulation: The natural insulating properties reduce condensation and prevent bridgingLong lifespan: Minimal maintenance and exceptional durability mean lower total ownership costsWet salt technology: more efficient and environmentally friendlyThe transition to wet salt technology is a game-changer in modern de-icing. By pre-mixing dry salt with brine, the thawing reaction is activated up to 15 minutes faster. Moreover, the spreading amount can be reduced by 20-30% with equal effectiveness, resulting in less environmental impact and lower costs.This advanced method requires both salt silos and brine tanks, often in combination with salt dissolving systems. The complete system ensures an efficient, environmentally responsible approach to de-icing.Customized solutions for every situationYour specific situation requires an appropriate solution:For municipalities: Compact systems that fit within existing municipal yards, with quick access for spreading vehiclesFor provincial services: High-capacity systems that can handle peak moments when the entire road network needs treatment simultaneouslyFor private enterprises: Cost-efficient, scalable solutions that guarantee safety without excess capacityA complete system can consist of:Fixed silos with capacities from 20 to 250 m³Mobile silos for locations where a permanent installation is not possibleBrine tanks in vertical or horizontal designs (20 to 300 m³)Salt dissolving systems for making brineAssociated platforms, drainage systems, and filling installationsPeriodic InspectionPrevention is always more advantageous than repair. An expert check costs only a fraction of what a failure during a winter peak can cost you—not only in repair costs but especially in operational delays when safety is at stake. With a periodic expert check, you can ensure your system always remains functioning reliably. This inspection includes:✅ Thorough inspection of all components✅ Measurement of wall thickness and material strength✅ Evaluation of ventilation provisions✅ Inventory of any wear or damage✅ Professional advice on maintenance and optimizationBy including an expert check in your maintenance plan, you ensure operational safety and maximize the lifespan of your investment.Choosing the right partnerYou can recognize the right partner for your de-icing solutions by:Proven results – Ask for reference projects that have been operational for at least 10 yearsTurnkey thinking – A partner who not only delivers but thinks along about the entire process of de-icingQuality certification – Look for ISO certifications specific to composite processingService orientation – Good support during the winter season is not a luxury but a necessityInnovation capacity – A partner who invests in R&D for increasingly sustainable solutionsComposite silos and tanks remain the gold standard for salt and brine storage, with their unique combination of durability, functionality, and low maintenance costs. With the right systems, you're not only investing in safe roads but also in a long-term solution that continues to function reliably year after year, even under the most challenging winter conditions.Are you ready for the next winter period? Let one of our specialists analyze your current situation without obligation. In a brief conversation, we'll map out your specific challenges and advise on possible optimizations—often achievable before the first frost. Contact us today for a free consultation.
Dust explosion safety: the importance of explosion panels in storage silos
When storing bulk goods and dust explosion hazardous products, safety always comes first. Effective explosion panels are an essential safety feature for any industrial silo. In this blog, we explain why explosion panels are crucial, what the advantage is of domed silo roofs, and how this combination maximizes safety.Explosion panels: essential protection against dust explosionsExplosion panels are advanced safety devices specifically designed to discharge built-up pressure in a controlled and safe manner during a dust explosion in a silo. The function of these panels is crucial:They limit or prevent serious damage to the siloThey protect surrounding infrastructure and equipmentThey minimize the risk of fire and personal injuryThey prevent a primary explosion from leading to a chain reactionDomed silo roofs: superior dust explosion safetyPolem produces silo roofs in a standard domed klöpperboden shape. This design offers significant safety advantages over the "chinese hat" shape often used in conventional metal silos:1. Increased pressure resistanceThanks to the optimally designed domed shape, the silo roofs can withstand a p-red of 1.0 bar. This technical advantage is essential for silos in which dust explosion hazardous products are stored. In comparison: metal silos typically withstand a p-red of only 0.5 bar maximum.2. More efficient placement of explosion panelsThe increased p-red value means that less surface area is needed for pressure relief. For composite silos, this means that all required explosion panels can be fully integrated into the roof, while metal constructions often need wall panels as well.Three concrete benefits for your operationsThis technical advantage translates into direct operational benefits:Maximum storage capacity: You can utilize the full capacity of the silo without having to account for a maximum fill level below wall explosion panels. This maximizes your storage efficiency and reduces the cost per ton of stored product.Improved hygiene: The design without flanges in the wall eliminates potential problem zones where product can accumulate. This significantly reduces the risks of mold formation, product spoilage, and bacterial growth – crucial for applications in the food and pharmaceutical industries.More compact construction height: Unlike metal silos, which often need to be built higher to accommodate wall explosion panels, composite silos with roof-integrated panels allow for a lower construction height – an advantage when applying for permits or in buildings with height restrictions.Professional installation for optimal safetyFor maximum protection, explosion panels are always installed flush (completely flat) with the inside of the roof. This seamless integration ensures that in the event of a dust explosion, the built-up pressure can escape immediately and with minimal resistance.As standard, these safety systems are equipped with robust safety railings. This essential addition prevents maintenance personnel from inadvertently standing on the vulnerable panels during inspection or maintenance operations.Specialized indoor installationsFor silos placed inside a building, additional safety requirements apply. In these situations, specially designed vent ducts are required. For these indoor installations, the explosion panels are always constructed in a round shape.This round shape is not an aesthetic choice but a technical necessity: rectangular or square explosion ducts must be extremely heavy-duty to guarantee the required pressure resistance, which is costly and often practically unfeasible.Responsibility and expertiseAccording to legislation, it is the responsibility of the client to determine whether the stored product is dust explosion hazardous and whether the silo should be equipped with appropriate explosion panels. Polem's market specialists are ready to advise on this and develop a safety solution that perfectly fits your specific situation.Every grain, every drop. Quality in, quality out.
