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.

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.

The roof of a silo: often overlooked, always essential
At Polem, everything revolves around the right flow. It starts with a strong foundation, but is equally determined by the top: the roof. It's one of the components we include in every design by default – and often adapt to the specific application. Where others see the roof as just a lid, we see it as an opportunity to eliminate risks and improve performance.That's why every Polem silo comes standard with a domed roof design. Not just for aesthetics, but because it's better in every respect. For safety. For durability. And for hygiene. Polem's pragmatic, confident approach ensures we deliver quality you can rely on.Why the roof mattersThe roof of a silo endures severe conditions:Overpressure during filling - Pressure can rapidly increase during pneumatic fillingUnderpressure during sudden product movement - When product collapses in the silo, it creates a suction force that strains the roofWeather influences such as wind, rain, and UV - Years of exposure to the elements places high demands on durabilityMechanical load from components - The roof must not only support itself but also the additional weight of equipment and installationsA poorly designed roof therefore poses risks. Think of deformation, lekkage, condensation, or even danger during explosions. Yet in many designs, it doesn't receive the attention it deserves. At Polem, we make the difference by giving it priority.Why Polem chooses a domed roofA domed roof – also known as a Klöpper design – distributes forces evenly across the entire surface. This makes it resistant to higher pressure differentials. Polem silos can standard withstand a P-red of 1.0 bar. For comparison: metal silos often top out at 0.5 bar or less.What does this mean for your business processes?Better explosion safety - For dust explosion hazardous products, the roof offers more resistanceSmaller and fewer explosion panels needed - Instead of using large areas in the silo wall, smaller panels in the roof will sufficeHigher capacity utilization - Because no explosion panels are needed in the silo wall, you can fill the silo to a higher levelSmarter with space and integrationOur roofs are not only stronger but also more intelligently integrated with all necessary components:Flanges for filling systems, filters, manholes, and measuring equipment are seamlessly laminated – eliminating additional risk of leakage or thermal bridges. This prevents condensation and product deterioration.Composite flanges instead of metal - Unlike competitors, we use fully composite flanges, which eliminates thermal bridges and guarantees better adhesion.Explosion panels are placed entirely on the roof. No flanges in the silo wall. This prevents stagnant product and increases hygiene, which is essential for food and pharmaceutical applications.Central filling connection - For even product distribution and to prevent tilting, we position the filling connection in the center of the roof.Benefits at a glance✅ Higher safety through better pressure resistance ✅ Less explosion surface area needed ✅ Better hygiene through smooth roof surface ✅ No thermal bridges or weak spots ✅ Optimal integration of all components ✅ More room for customized solutions ✅ Less maintenance due to durable construction ✅ Better utilization of your investmentThe difference between a silo and a Polem? It's in the roofAt Polem, we design each component as if it were crucial. Because it is. Since 1972, we've built a strong reputation in the Netherlands and beyond. We've seen cases where poorly placed filling connections led to tilting. Filters that clogged due to condensation from a poorly insulated roof. Explosion panels that didn't function properly due to obstructions in the environment.That's why we pay extra attention to the upper part of the silo. Because that's where safety begins.You build silos from bottom to top. But the top makes the differencePrecisely because we focus on the essentials, we know where Polem makes the difference. Our approach is pragmatic, challenging, and confident. We know that the roof design of a silo is not a side issue but a crucial factor for the safety, efficiency, and lifespan of your investment.Would you like to know what a good roof design can do for your specific situation? Or would you like an analysis of your current installation to assess whether it is safe and optimally designed? Our market specialists are happy to look at solutions that fit your business processes.It's not just storage. It's Polem. And the difference starts at the top.
The hopper makes the difference: why hopper design in silos is crucial
At first glance, a silo seems like a simple storage facility. But at Polem, we know that the hopper design forms the heart of an efficient and functional system. With over 50 years of experience, we have learned that the details in this design make the difference between a standard silo and a premium storage solution.More than just an exit pointThe hopper is much more than a simple discharge opening. It is an essential component that directly affects:The discharge quality of your productThe ability to completely empty the siloThe hygiene inside the siloThe lifespan of your investmentAt Polem, we design hoppers that perfectly match your specific application.Hopper angles for every applicationEach product behaves differently in a silo. That's why Polem offers hopper angles that optimize flow:Each product behaves differently in a silo. That's why Polem offers hopper angles that optimize flow:40° hopper angle: Ideal for food and feed applications such as sugar, salt, or starch. This angle ensures mass flow ('first in, first out'), essential for perishable products.60° hopper angle: Suitable for abrasive bulk goods such as fertilizer, cement, or lime. Core flow reduces friction and wear on the walls.Special angles (e.g., 30°): For unique products, we design custom angles tailored to your situation.The Polem difference: rounded transitionsA distinguishing feature of our silos is the smooth transition from hopper to cylinder. Unlike the sharp angles of metal silos, this offers:Better product flow: No build-up in corners, which improves hygiene - crucial for food and animal feed.Lower material stress: Less stress on the laminate allows for more efficient, stronger construction.Mass flow versus core flowWhen extracting bulk goods from silos, two main flow patterns emerge:Mass flow: The product moves as a whole through the silo, with the material that enters the silo first also exiting first (First in, first out). This is ideal for perishable products and prevents material buildup.Core flow: Here, a funnel-shaped channel forms in the middle while product along the walls remains stationary. This reduces wear but can lead to product aging and clumping in stationary zones.Solutions for difficult flowing products For products with poor flow properties, such as rice husk or bran, we combine:A hopper with the right angleA suitable vibrating bottomPossibly a deflector This integrated approach guarantees efficient flow, even with challenging materials.Prevention of segregationWith mixed products, such as animal feed, segregation is a risk. A well-designed hopper with mass flow keeps the composition consistent, which ensures product quality.Centric filling and emptyingFor optimal performance and safety, it is crucial that silos are always filled and emptied centrally. Decentralized filling or emptying can lead to slanting of the product, causing large, unevenly distributed forces on the silo and potentially creating dangerous situations.Customization for your situationNo two applications are the same. Our market specialists are happy to discuss with you to develop the ideal hopper solution, based on your product and processes.Investing in qualityA good hopper design is more than functionality – it's an investment in:Higher product quality through better flow and hygieneLower maintenance costs through reduced wearLess downtime due to reliabilityA longer life of your siloPolem expert checkFor existing silos, Polem offers the Expert Check. During this periodic inspection, our expert technicians check, among other things, the condition of the hopper and advise on any adjustments or maintenance. This helps you to ensure the optimal operation of your silo and extend its lifespan.Optimise your processesWould you like to know how the right hopper design can improve your production?

Precision storage in modern agriculture
The challenge: why storage is essentialIn today's agricultural sector, we at Polem understand that efficient storage is not a luxury but a necessity. Conversations with our agricultural customers reveal that the quality of storage systems directly impacts their business results. Moisture, product flow, and durability are challenges that many agricultural entrepreneurs face daily.What agricultural customers tell usIn our fifty years of experience developing storage solutions for the agricultural sector, we've learned a great deal from our customers. The problems they experienced with traditional steel silos – such as product clumping due to moisture and material remaining in corners and seams – have helped us better understand what's needed in the field.Experiences from poultry farmers: "Always perfect feed and no separation"Udo Baumeister and Stephan Werthmann, owners of Landwirt Baumeister in Breckerfeld, Germany, share their experience with our flat-bottom silos: "The flat-bottom silos are ideal; no separation and the feed always flows consistently.""We initially wondered if a flat-bottom silo would really make such a difference, but now we wouldn't want to be without it," says Baumeister. "When we heard about this silo from a colleague ten years ago, we already had several funnel silos from Polem. But I wasn't familiar with the flat-bottom. After positive reports from other poultry farmers and our feed supplier, we decided to take the plunge."The results proved convincing: "In the barn with the flat-bottom silo, we see higher laying percentages and better feed conversion compared to the two other barns with funnel silos. Our laying percentages are stable, the hens remain productive longer, and feed conversion has improved. We saw such a clear difference that we decided to replace our funnel silos with flat-bottom silos.""Very satisfied! No problems and easy to clean"Another experience comes from Rune Thomsen, manager of the Williamsborg estate in Denmark, a business with 110,000 broilers and more than 1,000 hectares of agricultural land where wheat, barley, rapeseed, and peas are grown."When we took over an outdated pig farm in 2015, we faced an enormous challenge," says Thomsen. "The old barns needed replacement, and we wanted to build a modern poultry farm with the best facilities. We chose Polem feed silos, and now – years later – we can say that we're still very satisfied with them."The Williamsborg estate uses six Polem silos: four 60 m³ and two 13 m³ for buffer storage. Thomsen particularly appreciates the hygienic aspects: "A major advantage is that the silos are easy to clean. We noticed this, for example, during a salmonella outbreak, when the cleaning process went smoothly."How different silo solutions address specific challenges1. Flat-bottom silos and quality preservationFor poultry farmers like Baumeister and Werthmann, the benefits of flat-bottom silos are concretely measurable:Continuous feed flow without interruptionsPrevention of separation of feed componentsFirst-in, first-out principle ensures that the oldest feed is used firstThe Air-Control system also ensures optimal temperature in the silo, preventing mold formation and feed quality loss. "This means less waste and stable nutritional value, regardless of weather conditions," says Baumeister.2. Hygiene and cleanabilityIn poultry farming, hygiene is a critical factor. Thomsen emphasizes: "The seamless construction prevents weak spots and keeps the feed in perfect condition. The silos are easy to clean, which proved crucial during a salmonella outbreak."This experience illustrates an important advantage of composite silos: due to the smooth surface and seamless construction, they are easy to clean and disinfect, reducing the risk of cross-contamination.3. Durability and ease of maintenanceThomsen appreciates the long-term benefits: "They are designed to last for years and remain in top condition, making our investment profitable in the long run. The combination of high-quality materials and thoughtful design ensures that we have experienced no problems with the storage or flow of the feed."Other customers also appreciate our composite construction primarily for:Absence of corrosion problems, even with aggressive fertilizersLong lifespan without visible degradation from UV radiationConsistent performance regardless of seasonal changesBaumeister confirms this: "The silos require minimal maintenance and ensure a constant feed quality, which is essential for the health and performance of our chickens."Automation and efficiencyModern agriculture demands efficient systems. Thomsen appreciates the advanced features: "The silos are equipped with automatic filling systems and sensors, allowing optimal management of our own grain buffer storage."Baumeister and Werthmann add: "Thanks to the right-angle transfer, the feed goes directly into the barn, without extra transfer points or sensors that could malfunction."These technical solutions directly contribute to operational efficiency:Fewer moving parts means fewer malfunctionsDirect transfer to the barn increases reliabilitySimple but effective systems reduce maintenance requirementsApplications for liquid product storageWith the brothers Hein and Lenus Waalkens, we've seen how the transition to composite tanks has led to what they describe as "reliable and solid storage of fertilizers." Their concrete experience aligns with what we hear from many agricultural customers.For liquid products, the choice of the right agitator proves essential. Our customers often start with standard 3 kW systems but sometimes switch to 4 kW HD agitators with increased service factor for more intensive use.The importance of maintenance and inspectionWhat we learn from our customers is the importance of regular maintenance. That's why we offer the Expert Check, where we work with customers to examine:The general condition of silos via an periodic inspectionEarly detection of potential problems to prevent costly damageAdvice on optimal use for specific applicationsWhy investing in quality storage pays offBased on customer feedback, we see that investments in high-quality storage systems pay off through:Reduced product lossesImproved product qualityLower maintenance costs in the long termFewer operational disruptionsAs Baumeister summarizes: "The flat-bottom silos from Polem have proven to be of tremendous value to our business. Our hens perform better, the feed is optimally utilized, and maintenance is minimal. It's an investment that more than pays for itself."Thomsen agrees: "The Polem silos offer our business not only convenience and reliability but also peace of mind. They contribute to efficient feed storage and an optimal living environment for our broilers."For each agricultural business, the specific benefits differ depending on what is stored and under what conditions. But the feedback we receive consistently confirms: the quality of storage directly influences the quality of the end product.For more information please check our website or contact us.

Composite vs. steel, aluminum, PP, PE and plastic silos and tanks
At Polem, we have been using high-quality composite materials since 1972 to create storage products that are seamless, strong, and mirror-smooth. In this blog, we dive deeper into the differences between composite and other materials for silos and tanks.What is composite?Composite is essentially a compound material consisting of two or more components with different physical or chemical properties. When these components are combined, a new material emerges with properties superior to those of the individual constituents.For Polem's silos and tanks, we use glass fiber reinforced plastic (GFRP), a specific type of composite. GFRP consists of:A polymer matrix (often polyester or epoxy resin)Reinforcement through glass fibersThis results in a material that combines the flexibility and design freedom of plastic with the structural strength of glass fibers.Composite versus other materialsGFRP (Glass Fiber Reinforced Plastic)GFRP is a specific type of composite. The term 'composite' is broader and can include other reinforcement materials, such as carbon fibers or aramid. At Polem, we use GFRP because of its excellent combination of strength, durability, and cost-effectiveness.PolyesterPolyester is often the resin matrix used in GFRP. It is therefore a component of the composite, not the composite itself. It serves as a binder for the glass fibers and provides chemical resistance.PP (Polypropylene) and PE (Polyethylene)These are thermoplastic polymers used without reinforcement for various applications. They are more flexible than composite but lack the structural strength and durability provided by glass fiber reinforcement.Steel and aluminumTraditionally, silos and tanks are often made of steel or aluminum. Although these materials are strong, they have significant disadvantages compared to composite:They are more susceptible to corrosionThey have poorer thermal insulationThey require welds and joints that can weakenThey have a rougher surface leading to more product adhesionThe advantages of composite for silos and tanks1. Seamless constructionOur composite silos and tanks are manufactured in one piece, without seams or welds that can leak or weaken. This results in hygienic storage where no product can accumulate in crevices or corners.2. Exceptional strengthDespite their relatively light weight, our composite structures are exceptionally strong and can safely store large quantities of material, even under demanding conditions.3. Mirror-smooth finishThe interior of our silos and tanks is mirror-smooth, which ensures:Better product flowMinimal product adhesionEasier cleaningImproved hygiene4. Corrosion resistanceUnlike metal alternatives, composite is virtually immune to corrosion, which significantly extends lifespan and reduces maintenance costs.5. Thermal insulationComposite naturally has excellent insulating properties. The insulation value of a tank or silo with 50 mm PU foam is comparable to that of a metal tank insulated with 100 mm rock wool and aluminum plating.6. Low maintenanceDue to its durability and resistance to both mechanical and chemical influences, composite products require less maintenance than conventional alternatives.Practical exampleIn the food industry, hygiene is crucial. The seamless finish of composite silos prevents product buildup in corners and crevices, which can cause mold formation and bacterial growth. Additionally, the mirror-smooth interior wall is ideal for products that are difficult to flow, such as powders and granulates that stick to rough surfaces.A customer in the dairy industry noticed a significant improvement in product flow and a reduction in cleaning time after switching from steel silos to composite. Additionally, the thermal insulation proved to be much better, leading to less condensation and better product quality.In the industrial sector, where many chemicals are used, the corrosion resistance of composite proves its value. While steel tanks regularly need maintenance or replacement due to degradation, composite tanks remain in perfect condition for years.FinallyThe choice of the right material for your silos and tanks directly influences the quality of your processes and end products. Composite offers clear advantages over traditional materials such as steel, aluminum, and unreinforced plastics.Every grain, every drop. Quality in, quality out.
