Configurator

Rune Thomsen is manager of broiler farming on the Williamsborg estate in Denmark.The company grows wheat, barley, rapeseed and peas on more than 1,000 hectares.They also have 110,000 broiler chickens.

In 2015, an outdated pig farm was acquired that was in urgent need of renovation. The old stables were dismantled, leaving a blank canvas for the future of the farm. Over the next two years, 2015 and 2016, two impressive, identical sheds emerged from the dust and ruins. These new buildings were intended to house up to 55,000 broilers each, and they promised a new era for the company. Surrounding these shiny new sheds are a total of six impressive broiler feed silos from there nowned Polem brand. Four of these silos have a generous capacity of 60 cubic meters, while there maining two have a slightly more modest capacity of 13 cubic meters. These smaller silos are used as buffer storage for their own wheat which is mixed with the feed coming from the factory. Equipped with top and bottom sensors they are automatically filled from the bigger storage behind them. Due to current wheat prices this is not in use at the time, but it works really well and will be used again in the future.

The seamless construction of the silos eliminates potential weak points, safeguarding the stored feed against contaminants and maintaining optimal storage conditions.

The sheds on this typical Danish poultry farm, each with an area of approximately 3,000 square meters, followed the well-known pattern of broiler farming. Feeding lines, an ingenious combined system for ridge and longitudinal ventilation, inlet valves, six water lines and a generous amount of thick litter provided the optimal environment for the chicks.

It is always a great feeling to see the result of hard work, and that is certainly true of our recent production of four feed silos! These imposing silos, each with a diameter of 3.5 meters and an impressive capacity of 200 m3, have just come out of production and are now sitting on our site shining.

What makes this project extra special is that we produced these silos for a valued client as part of a larger order. A total of seven of these impressive silos will be made to meet our customer's needs. It is a beautiful sight to see these silos stretch out against the horizon as silent witnesses to our craftsmanship and dedication to quality. Every detail, from the sturdy construction to the precise workmanship, has been done with care and precision to ensure that these silos will provide years of service.

As a team, we are proud of what we have accomplished and look forward to completing the remaining silos in this order. It is an honor to work with customers who trust us and give us the opportunity to contribute to their success.

Proud of our recent collaboration in Belgium! With this customer, we were allowed to deliver a tank for indoor placement. Together with our dedicated Service Engineer, we successfully installed the tank in the building.

What made this delivery extra special?

✪ It was the use of a special resin type and laminate construction to safely store the customer's medium (mixed acid). In addition, we carried out a Vlarem Keur incl. water test to ensure that everything was fully compliant;
✪ Our steelwork had to be treated with a duplex system (hot-dip galvanised and polyurethane coating in fire red), ensuring durability and safety;
✪ The tank had to be placed inside the production area among already existing production infrastructure, challenging logistically!

The cooperation with our client was extremely pleasant and we eagerly look forward to future projects.

Harm Rijkers has been working with two Polem flat bottom silos since July 2021. After a year he shared his experiences: “The flat-bottomed silos are great. The feed never gets stuck and there is much less segregation.”

 
On the farms of the Rijkers family from Vessem in the Netherlands, there are various silos near the pig and laying hen houses. At the end of 2020, they set up their two-storey barn for one star Better Life hens. In consultation with the supplier, Rijkers opted for the Polem flat bottom silos. “Most of our silos are Polem silos with hoppers. The food can sometimes linger there, especially in humid weather. We have now experienced both summer and winter with the new silos and feeding is going great; no segregation and the feed runs smoothly.”
Rijkers installed two flat bottom silos of 70 m³ each and a classic funnel-shaped silo for grit at the new barn. Harm Rijkers indicates that he mainly followed the advice of his Polem dealer. “As a poultry farmer you don't often buy a silo. After all, they last for years.”
Robust turn-out system
During feeding, the feed flow is constant through the discharge system with the sweep conveyer so that bridging is prevented. The feed does not separate and the discharge system ensures that feed that enters the silo first, also flows out first.
At the end of the laying round, the silo must be completely emptied. “The manhole is next to the conveyer. The sweeping conveyer goes flat over the floor there. We will then have to scoop out the bottom layer. I don't expect any problems with it," says Harm Rijkers.
 
Out of sight
The silos are interconnected for good ventilation. “We had weigh bars installed under it. I can see how much food is left in my mobile. If the bulk truck is a bit earlier, I quickly check whether the feed fits in it.”
The two flat-bottomed silos are placed behind the egg room next to the barn. “We like the look of the company better without the silos in the foreground. The disadvantage is that the driver of the feed truck cannot reach the silos directly. With the air cleaner system, he doesn't have to use a dust bag," says Harm Rijkers. With this volume he can order full trucks of feed and receive the maximum discount.
 
Rijkers is very satisfied with the new barn. “We have invested in all aspects of ease of work and efficiency. The flat bottom silos are part of that.”

Retention of product quality and nutritional value

Many livestock farmers are looking for storage options that protect the tenability, product quality and nutritional value of their products. So it is important to know Polem produces composite (fibre-glass reinforced plastic) storage tanks specially for the storage of wet by-products in the food industry.

While designing these tanks, Polem paid specific attention to the fluctuating product viscosity and

aggressiveness. In addition, a smooth, seamless interior wall is created during the specialist spray-wrap process. This wall gives you excellent outflow properties and is very easy to clean.

Complete standard model

The wet by-product tanks are constructed for a standard bulk weight of 1,000 kg/ m3

and are available in diameters of 280, 300, 350 or 400 cm, with volumes of 35 - 150m3.

Properties:

  • DN600 inspection hatch in cylinder with blind flange
  • maximum temperature up to 50°C
  • convex or flat bottom
  • inspection and access door if the tank has a skirt
  • underside tank bottom 75 cm
  • fitted with filling and discharge opening Ø 150mm
  • hot-dip galvanised anchoring consoles
  • plastic venting line
  • ertical structure supported on full-polyester skirt structure

Ready for user-specific options

More and more livestock farmers want to adapt their wet by-product tanks to their individual situation. Popular options include:

  • a choice of agitators (A, B or C)
  • increased bulk weight to 1300 kg/m3
  • temperature resistance up to 75°C
  • centrifugal pump 4 kW
  • displacement pump 10 or 25 m3/hour
  • stainless steel shearing partitions
  • 6” brass gate valve (where necessary, with lever operation)
  • 6” brass gate valve with galvanised bend and 4” VK tanker coupling
  • other sizes.

In February 2022, we delivered four Polem tanks for the storage of saltwater to a Norwegian customer.
Three upright open tanks and one horizontal closed tank on fully composite saddles.
The transport from Lemmer to Sarpsborg, about 80 km below Oslo, went by sea from Lemmer via Harlingen and was neatly arranged for us by Shipyard Lemmer and Wagenborg Nedlift.
The tanks were delivered to the customer's location within 6 days!

For M.O.T.T. Polem has once again been able to realize a beautiful tank park. 12x 9 meter diameter tanks for the storage of oils and fats. Good cooperation between the customer and Polem results in the best specifications and the most favorable price. Entering into a dialogue with our customer early in the process, we achieve the best results, we streamline the preliminary process but also the production process.

De-icing roads with less salt is not only better for the environment, but also ensures a safer road.

By spraying the road salt with a certain concentration of brine, it will stick better to the road. As a result, the salt won't blow away and can be spread much more accurately. In addition to significant cost savings, this also saves on the burden on the environment.

Our salt dissolvers, also known as brine making installations, are available in different diameters and designs, with both manual and automatic operation.

In the photo you see a salt silo of 50 cubic meters above the brine making installation and two brine storage tanks of 50 cubic meters each. This German winter service is now completely ready for the winter season.

We previously launched the silo configurator on our website: a handy tool with which you can quickly request and receive a budget quotation for your silo.
The version for a solution for your liquid products has recently become available: the tank configurator.

In addition to silos, Polem has been supplying tanks for the storage of liquid products, fats, chemicals and sauces for years. These products can be stored very well in a composite tank. We supply tanks up to 9 meters in diameter and a storage capacity up to 1,500 m³.

Not sure whether your product is suitable for storage in a composite tank? Please feel free to contact one of our account managers. They are able to advise you well.

Sometimes Polem silos serve a different purpose than the storage of goods.
 
For example, we were asked if we wanted to supply silos for an art project in the 'Old Church' in Amsterdam. The silos, which are suspended from the ridge of the church building, are open at the bottom and are used as an extra sound box to play sound fragments.
 
The project is explained on the website of the monumental church building: After numerous visits to the church and extensive artistic research, the Scottish artist Susan Philipsz presents her context-specific sound installation, The Fall in the oldest building in the city. Philipsz is also sometimes referred to as a sound architect.
 
The smooth finish ensures good reverberation of the sound, especially in a round silo. That was reason enough for this artist to opt for the smooth and seamless Polem silos.
 
A special project that also produces special photos!

Clean starch silos
 
A few years ago we supplied a starch silo to a cardboard factory in the United Kingdom. This starch is used to make the glue to bond the layers of cardboard. This silo was recently inspected and the inspector's response was as follows: “Since the installation, no problems have been identified at this silo. And I must also say that this is one of the cleanest starch silos I have ever seen!”

Are you looking for a silo for the storage of your ingredients or end products and are you curious whether composite is the right choice? Please feel free to contact one of our account managers. They have years of experience and can advise you well.

Styn Claessens is sure about it: “Polem flat bottom silos work well.” Together with his parents and neighbour Peter Janssen, he owns the layer poultry farm Yverde in Ysselsteyn in the Netherlands. The barn houses 51,000 laying hens that produce three star “Beter Leven” (Better life) eggs. The Claessens family also owns another layer poultry farm and Peter Janssen owns two other layer poultry farms.

The Polem silos on the side of the barn stand out immediately. “That was also one of our arguments; the total appearance, including the appearance of the flat bottom silos. Peter and I both like them," says Styn Claessens. They opted for the green silo roof. “That suits Yverde well. In Spanish ‘verde’ means green.”

Proven technology
Claessens and Janssen built the new company in Ysselsteyn in just six months. “In 2017, when we bought the neighbour’s farm, we started making plans and applying for building permits,” Styn recalls. The first drawings already showed Polem silos. Two flat bottom silos of 60 m³ each, good for 40 tons of laying poultry flour each.

The partners also have Polem flat bottom silos at their other farms. “It was obvious to us that we also installed Polem flat bottom silos at our new joint company. The biggest advantage of this silo is the prevention of segregation. It is a proven technique. We feed flour feed which gives a chance of bridging, but with these silos we have no problem with that. As a poultry farmer, you have no extra work with these silos.”

Easy working
For Yverde, the poultry farmers consciously opted for the 60 m³ size, so that an entire bulk truck can always be unloaded. “We have placed two silos near the barn and can always empty the silos. You can see the feed in the silo dropping evenly.”

Claessens explains that they have had a man hatch installed at the outlet pipe. “That is exactly above the takeover point. If the auger in the silo is broken, we can always feed easily.” There is a man hatch on top for easy cleaning of the silo. With vlog/non GMO it is mandatory to clean the silo every round. The poultry farmers also opted for a PVC vent pipe: “Simply simple, no filters that can be blown apart by the increasingly pressurised  bulk trucks.”

Styn Claessens concludes: “Our starting point is: What do we think is best? And that's what we choose. We are happy with these flat bottom silos.”

Crusta is a company in the Dutch village Urk. The company is specialized in live shellfish, such as King Crabs, Canadian Lobsters, North Sea crab and Oysters.
To keep the animals in optimal conditions, Crusta created the perfect environment: The Crusta Ocean. This is a state-of-the-art salt water auto-refreshing system with a capacity of 500.000 litres, which closely recreates the natural living conditions of the shellfish.
That's were Polem was able to help Crusta: we supplied them two isolated 35m3 tanks, with a diameter of 2,80 m to store fresh seawater. This helps them to keep the Crusta Ocean in perfect condition. The salt seawater will not harm the storagetank, because composite is not sensitive to corrosion. 

After installation of the tanks, the customer replied to us: "The tanks are beautifull and with compliments to the truck driver for his carefull delivery!" 
 

In the Belgian town of Bree, Siloba has installed composite storage silos at a new bakery.

The 6 Polem silos are placed outside the building and are used for the storage of flour. A large 37-tonne silo for white flour and 5 smaller 7-tonne silos for different types of flour.
All silos are fully equipped with filter, explosion panel, silo weighing and bin activator. The flour is transported via a spiral transport to the weighing bunker in the bakery.

Christophe from Siloba: "In a separate area of ​​the warehouse, a mini dosing station is placed with 12 small silos in stainless steel, where the different flour mixes are dosed into a separate weighing bunker via pneumatic transport. Both weighing bunkers then bring the flour together in a mobile kneading tub. During the adding of the flour, water, liquid yeast and salt are dosed directly into the same kneading tub via the recipe computer. The entire installation was automated with a Siloba PLC bakery software."

Polem silos and tanks made of composite are very suitable for the storage of foodingredients due to the good insulating properties, seamless inner walls and optimal hygiene. Read more about the advantages of composite silos here.

Salt dissolver and brine tanks for the city of Vienna

Dealing with slipperiness on the road is a matter of acting quickly at the right time.
Through our dealer Blumer & Lehmann, Polem supplied 3 composite brine storage tanks and a salt dissolver for ice control in Vienna.
The smaller tank is the salt dissolver that ensures the correct concentration of brine water. The brine water is stored in the three tanks of 2400 mm diamter each and with a capacity of 45 m3 per tank. This way they can start immediately when the roads need it.
The beautiful color orange is at costumers request. We think it is a good choice!

This Austrian winter service works with large wooden silos for the storage of road salt. Wooden silos are mainly used when really large silos are needed (600 m3) In recent years, Polem has also supplied many silos for salt storage for winter services. Composite silos are an excellent choice because of their resistance to corrosion and chemical stress, the high insulation value and no bridging.

Would you like to know more about good and efficient ice control with brine? Please contact our account manager.

For Dutch company Rijnzate (specialized in the storage and transhipment of animal feed raw materials, such as maize, barley and wheat), Polem has been able to realize a great project;  replacing 14 grain silos from old steel silos to new Polem composite silos. 
Each silo is over 21 meters high and 5 meters in diameter. Approximately 250 tons of grain can be stored in one silo. Replacing the silos was a huge job, however the technical people at Polem kow how to handle in complex projects. Large cranes at the building site were able to place the new silos on their final position.

In 2019, Agrifirm invested in eight new Polem flat-bottom silos at its Research Farm Laverdonk. "To study the effect of feeds, it would be ideal to have the feed factory next to the barn. That is of course not possible. With these flat-bottom silos we approach this ideal the best, "says Harold de Louw, Laverdonk manager. With the eight flat-bottom silos, the research company can test eight different feeds or mixtures thereof. "By using flat-bottom silos, the flour reaches the laying hens as uniformly as possible," explains De Louw.

The studies at Research Farm Laverdonk are aimed at further improving the returns of poultry farmers, for example by improving the technical result, efficiency or cost-price savings. "It is important that the feed recipe that we make reaches the chickens from the feed factory as well as possible. With a flat bottom silo, the flour remains uniform and reaches the chicken without segregation, "explains Anne ter Braak, Nutritionist in Laying Poultry. Each department has its own feed valve and can feed accurately per gram. This way of working contributes to the accuracy of the tests with the aim of measuring the influence of feed composition and structure on feed intake, feed efficiency and health.

Translate knowledge into practice

The Innovation Team, of which Laverdonk is a part, works together with universities, suppliers and research centers worldwide. With their own protocols and priorities, they can quickly respond to demands from the market. "Under controlled conditions, including the use of the flat-bottom silos, we can demonstrate very small differences," explains Ter Braak.

The flat bottom silos contribute to the accurate provision of the feed, which means that the differences found between the treatments can largely be explained by the differences between the test feeds. "This allows us to develop feeds under controlled practical conditions and thus translate knowledge into practice and optimize the return on the farm," says Anne ter Braak. "The discharge system with the sweeping auger ensures a continuous product outflow so that there is no bridging. The composition of the feed is therefore the same continuously. That is good for our tests, but certainly also at practice laying poultry farms, "Harold de Louw concludes.

Polem launches new logo, corporate identity, website and corporate film

A new vision and mission require a new look. With that in mind, Polem has worked hard over the past year to develop a new logo, a modern corporate identity, a completely renewed website and a corporate film that clearly reflects what Polem stands for. The results are impressive!

Sturdy silos with very long life span

Polem offers you a broad range of sturdy composite silos with diameters of up to 9.0 metres and capacities up to 1,500m³. These silos are mainly used to store products such as biomass, wood pellets and starch as a binding agent. However, alternative applications such as limestone products for flue gas systems or co-firing in boilers also regularly occur.

One of the reasons why people prefer composite is its high insulation value, which means there is almost no condensate formation in the silo. This results in almost no attachment to the interior of the silo, which, in combination with the smooth and seamless inside, leads to an optimal product outflow.

Depending on your requirements, you can choose to use standard or customised models. Where necessary, with optional drive-under steel structures, platforms, cage ladders, and roof rails. Or other options, such as dust filters, vibrating bottoms, extra insulation, volume measurement, explosion panels or weighing systems. Whatever your requirements, Polem can help you achieve the desired end result.

On the test point of 1 January 2020, Renewable Energy was already contributing 21.3% to worldwide energy consumption. This market is in flux and Polem is developing with it. Based on almost 50 years years of experience with composite silos and tanks, Polem has a huge advantage in terms of its technical knowledge. For example, do you want to store co-products, glycerine, biodiesel and biomethanol in tanks or biomass, wood pellets and starch in silos? Polem has already developed the proven technology. Polem also has various partnerships with universities and composite knowledge centres for the use of composite as a fully circular raw material in the production of new materials. As already mentioned, Polem is developing all the time.

Do you have any questions or specific wishes? Involve your Polem specialist in your project at an early stage. During the total project implementation, you will be professionally supported by experienced project managers that use customer-specific 3D drawings to help you to flawlessly achieve your desired end result.

In the paper & pulp industry, a huge amount of work is performed with polyvinylacetate glue, also called PVA. In addition, aggressive chemicals such as bleach and chlorine are often used. Everybody knows how these liquids affect concrete, aluminium, steel or stainless steel. That is why tanks manufactured from composite are used more and more often to store these types of products. Precisely because process continuity and safety are important points of focus in this industry, the tanks are also manufactured with double walls so that production is not disrupted after a possible leak. An additional advantage is that composite has good insulating properties, so you also save on your energy costs. Last but not least, the seamless, smooth interior helps prevent the product from becoming attached to the wall, so you also save on cleaning time and downtime.

Polem supplies these standard tanks in vertical or horizontal models and volumes of up to 50m³. Needless to say, there are also applications for which larger volumes are desirable. In other markets, Polem develops silos and tanks with volumes of up to 1,500m³ and is therefore excellently qualified to fulfil your specific requirements in a professional and sustainable way. The tanks include optional leak detection, pipes, supports, platforms, cage ladders and transfer platforms and can also cater to other specific requirements.

Silos

For the storage of starch, pigments, colourants, colour binding agents and various other raw materials, Polem has a number of standard composite silos with volumes of 80, 100 and 120m³. For specific applications, however, Polem also develops silos with volumes of up to 300m³.

The great advantage of these composite silos is that they are resistant to the aggressive properties of the widely-used products. Thanks to the high insulation value of composite, there is no condensate formation in the silo. And there is also no bridging. In addition, the interior is smooth and seamless and guarantees maximum product outflow.

Are you looking for a standard or a customised silo? In either case, your Polem specialist will help you make the right choice. Do you also want optional cage ladders, transfer and operating platforms, dust filters, volume measurement, weighing systems and screw jacks? Click here and send your requirements to a Polem specialist. We will then help you achieve the best possible result.

For almost 50 years, Polem has been a reliable point of contact for system integrators and end customers in the paper & pulp industry. This market is characterised by a broad-based competitive field with a global character. Process continuity and safety are therefore important points of focus that carry considerable weight when choosing the right silo or tank. And Polem has the perfect solution for this: composite.

Compared to concrete, aluminium, steel or stainless steel, composite has countless advantages. They include:

  • excellent chemical resistance
  • very smooth and seamless interior walls, minimising product adhesion
  • high insulation value, so almost no condensate formation       
  • no bridging
  • excellent outflow properties
  • suitable for both interior and exterior use
  • extremely quick and easy to clean
  • designed for the ‘First-In-First-Out’ principle
  • extremely suitable for the storage of explosive products in an ATEX environment

Clean starch silos

You will need to store the brine created in the Polem salt dissolvers in relatively large storage tanks so that you always have a buffer in stock. To make this possible, Polem has a standardised range of composite tanks in vertical or horizontal models with volumes of 20 – 300m³. These tanks, available in a number of standard or customer-specific diameters, can be manufactured with double walls and can include leak detection, connections, pipes and supports. As with the silos, you can also opt for platforms, cage ladders, transfer platforms or other individual requirements.

Your advantage:

  • very smooth interior wall with high chemical resistance to the aggressive brine
  • minimal maintenance and very long life span
  • available in every RAL colour
  • large storage capacity of up to 300m³.

Projects

Salt dissolvers

In collaboration with a number of carefully selected partners, Polem develops composite salt dissolvers – also called brine creation systems – with capacities up to 15,000 litre/hour.

In the future, unsaturated brine will be used more often for scattering and spraying. Thanks to this ‘new’ method of ice control measures, less salt will escape into the natural surroundings. Another advantage when spraying unsaturated brine is that it is no longer necessary to ‘run in’ the road, which is a particular advantage on cycle paths. In addition, the use of brine is mainly regarded as a means of realising preventative ice control measures.

These salt dissolvers are available in a variety of diameters and models, with both manual and automatic controls.

Projects

Silos

To quickly load your spreaders, Polem supplies a wide range of standardised road salt silos, including drive-under supports.

These composite silos with volumes of 20 - 250m³ are resistant to the aggressive properties of salt and are available in a number of standard diameters. Thanks to the high insulation value of composite, there is almost no condensation in the silo. This minimises the risk of bridging. In addition, the interior is smooth and seamless, resulting in an optimal product outflow.

For the drive-under supports, you can opt for a number of standardised clearance heights and widths. Or you can opt for a customised solution. This also applies to the optional platforms, cage ladders and transfer and operating platforms. If you require additional options, such as dust filters, volume measurement, weighing systems and screw jacks, Polem can help you achieve the desired end result.

If you cannot install a permanent silo at your location because it is difficult to obtain a permit, Polem can help you with a mobile silo.

Your advantage: 

  • Quickly load and unload road salt

  • Very smooth interior wall for optimal outflow of road salt
  • High insulation value, so almost no condensation
  • Composite is corrosion-resistant
  • Minimal maintenance and very long life span
  • Available in every RAL colour

Polem offers you a special range of composite products for ice clearing. They include silos, mobile silos, tanks and salt dissolvers, which are delivered to you as a reliable total turn-key solution.

In this context, a minimal environmental impact is essential. That is why companies often opt for a combination with a salt dissolver. Then you can very accurately spread salt wet, dry and combined so that less salt escapes into the environment. During the total project implementation, you are professionally supported by experienced project managers who use customer-specific 3D drawings to help you flawlessly achieve the desired end result.

Like the composite silos, the horizontal or vertical composite tanks are also ideal when you want to store your liquids hygienically. After all, these composite tanks also have a seamless, smooth interior, which means they can always be emptied with almost no residue. In addition, they are very resistant to chemicals, are corrosion-resistant, are effective at temperatures from -40 to +100 ºC and are very durable, which in turn means a favourable price-quality ratio.

Needless to say, under certain conditions extra insulation or heating may be required to keep the stored products at the desired temperature. Or do you want to include other options such as cage ladders, top rail, work platforms, transfer platforms or special agitators? Polem can help you! With composite tanks in diameters of up to 9.0 metres and capacities up to 1,500m³.
