FAQ

Frequently asked questions

Food

Can temperature sensors and level measurement systems be integrated?

Yes, we integrate various measurement systems such as temperature sensors, level detectors, pressure sensors, and pH meters according to your specifications.

How do I maintain the quality of my product during storage?

The excellent insulation value of GRP keeps the temperature stable and prevents condensation. The seamless construction prevents contamination, and the FIFO property at 40° funnel ensures that the product is not stored for too long.

Do Polem silos and tanks meet food safety requirements?

Yes, we only use FDA-approved resins that have been tested in accordance with EU1935/2004 for contact with both dry and liquid foodstuffs. Our products are food safe, tested, and certified.

What if my silo or tank is damaged?

Our service team can repair most damage on site to restore it to its original strength. Thanks to the flexibility of GRP, local repairs can be carried out without replacing the entire structure.

How can I prevent bridging in my silo?

Bridging can be largely prevented by using the correct hopper angle and smooth inner wall. For products that are difficult to flow, we can integrate a vibrating bottom.

Can Polem silos and tanks be placed outdoors?

Yes, GRP is weatherproof. UV-resistant, frost- and heat-resistant. No rust, no painting required. The good insulation value (λ = 0.17 W/m·K) prevents condensation.

Can you customize silos to integrate seamlessly with our systems?

Yes, we can adapt our silos so that they can be perfectly integrated into your existing systems. 

Can I have my existing silo or tank modified or expanded?

Yes, we can modify or expand existing silos to meet changing needs.

How does Polem ensure that the storage tanks meet hygiene standards?

Our tanks are made of corrosion-resistant material, a composite material. In addition, we can apply special coatings and treatments to extend the life of the tanks.

How often should food storage tanks be cleaned and maintained?

The frequency of cleaning and maintenance depends on the type of product stored and the operating conditions. We recommend regular inspections and periodic cleaning to ensure the safety and quality of the stored food.

For which applications in the food industry are your products suitable?

Our storage tanks and silos are suitable for various applications, including the storage of oils, sugar, cereals, dairy products and other food ingredients.

How often should I have my silo or tank inspected?

We recommend performing a visual inspection yourself every month and having a professional Polem Expert Check carried out every 3 to 5 years. This prevents unexpectedly high repair costs and extends the service life of your silo or tank. The recommended frequency depends on various factors: the type of medium you store, how intensively the silo or tank is used, and how often it is filled and emptied. For daily or heavy use, we recommend having inspections carried out more frequently — for example, a professional check every year. For less intensive use, the interval can be longer. Regular checks ensure that your installation remains safe, reliable, and in optimal condition.

How do I determine the right capacity for my feed silo?

The capacity depends on your feed consumption, delivery frequency, and available space. As a rule of thumb, for 100 dairy cows, you should calculate approximately 80-120 m³ for a period of 3-4 weeks. Our specialists will be happy to advise you on the optimal dimensions.

If I need a loose part for a silo, can Polem help me with this?

Yes, we can provide you with spare parts for your silos. Please contact our after sales department with the specifications of the part you need, and we will help you find the right solution.

Services

Bieden jullie ook technisch advies?

Zeker, onze marktspecialisten en engineers geven advies over productkeuz, capaciteitsberekeneningen, productstroming, veiligheidsaspecten en procesoptimalisatie.

Hoe lang duurt een gemiddelde installatie?

Voor een standaard agrarische silo: 0,5-1 dag. Voor complexere industriële installaties met veel aansluitingen: 1-3 dagen. Wij plannen dit vooraf in overleg met u.

Kunnen jullie ook installatie verzorgen?

Ja, wij installeren op verzoek zelf of in samenwerking met de systemintegrator. Onze ervaren monteurs zorgen voor vakkundige plaatsing. 

Hoe worden grote silo’s getransporteerd?

Silo’s met een diameter tot 9 meter leveren wij in één stuk af. Dat doen we, waar mogelijk, via binnenvaart of met speciaal transport over de weg. Voor dit soort transport zijn vaak uitzonderlijke maatregelen en vergunningen nodig. Polem helpt u bij het regelen van vergunningen en begeleiding tot de afstemming met lokale autoriteiten. Zo bent u verzekerd van een vlot en veilig transport van uw silo of tank.

Verzorgen jullie het transport van silo’s en tanks?

Ja, wij kunnen het transport verzorgen of u regelt dit met uw eigen transportpartner. Wij adviseren over de beste transportmethode afhankelijk van afmetingen, locatie en toegankelijkheid.

Werken jullie ook samen met internationale systemintegrators?

Absoluut. Wij hebben ervaring met projecten wereldwijd en kunnen ondersteuning bieden in verschillende talen. Onze technische documentatie is beschikbaar in Nederlands, Duits en Engels.

Bieden jullie ook projectmanagement voor complexe projecten?

Ja, onze ervaren projectmanagers coördineren het volledige traject vanaf ontwerpfase tot oplevering en nazorg. Wij stemmen af met alle betrokken partijen en zorgen voor tijdige levering volgens planning.

Wat houdt de samenwerking met systemintegrators in?

Wij werken nauw samen met systemintegrators door middel van gezamenlijke projectplanning, het delen van technische specificaties en heldere communicatie. Zo zorgen wij ervoor dat onze silo-oplossingen naadloos passen binnen het totale systeemontwerp.

Hoe snel kunnen jullie servicevragen oppakken?

Voor spoedeisende reparaties streven wij naar binnen 24-48 uur ter plaatse te zijn. Reguliere inspecties worden binnen 1-2 weken ingepland. Voor groot onderhoud hanteren wij kortere levertijden dan bij nieuwbouw.

Waarom zou ik voor Polem diensten kiezen in plaats van een lokale partij?

Als fabrikant kennen wij onze producten het beste. Onze monteurs zijn gespecialiseerd in GVK materiaal en hebben ruim 50 jaar ervaring. Wij werken met originele onderdelen, herstellen tot oorspronkelijke sterkte en bieden garantie op uitgevoerde werkzaamheden.

Welke diensten biedt Polem aan naast het leveren van silo’s en tanks?

Polem biedt complete dienstverlening van ontwerp tot nazorg: advies en engineering, samenwerking met systemintegrators, transport en installatie, inspecties en onderhoud, schadeherstel, aanpassingen en upgrades, plus technische ondersteuning. Wij blijven betrokken, ook na levering.
