Frequently Asked Questions

What are the benefits of a Tankwell composite tank container?

The benefits of Tankwells’ lightweight tank containers range from significant tare weight reduction, lower CO2 emissions, and improved thermal performance. Tankwells’ tank containers can transport up to 5% more payload. The 50% improved thermal insulation results in a reduction of heating or cooling in your supply chain. Due to the 5% extra payload, your transport becomes more efficient, resulting in 5% lower carbon emissions. Our tank containers are available in different sizes and types.

What is the return on investment in years of the additional investment in a Tankwell container?

The Tankwell container weights 1,5 ton less than a conventional steel container. For every 1000KG weight reduction, we calculate a decrease of EUR 5000- of the total shipping costs. This implies that the additional investment required for the Tankwell container could be repaid within 2,5 – 3 years. Also, it reduces CO2 emissions and fewer traffic jams.

The design and the applied materials selected for the Tankwell container achieve a lifespan comparable or more prolonged than conventional steel tank containers if handled correctly and professionally. It means the Tankwell container will save you time and money for the majority of its life span.

How sustainable are Tankwell tank containers?

The production of Tankwell tank containers has a lower CO2 footprint than stainless steel tank containers. Even if 90% of the steel in conventional tank containers is recycled and no recycled materials are applied in Tankwell tanks, Tankwell tanks’ production still requires 2500 kg less CO2. For a full explanation of the production, life cycle, and end phase, read here.

What are the weight of a Tankwell container and the total payload?

A Tankwell tank container weighs on average 2,5 tonnes. In international freight logistics, a maximum weight of 40 tonnes is allowed on Dutch roads. The average weight is 8 tonnes, a container chassis three and an empty conventional steel container weighs 4 tonnes. This means that 25 tons of cargo can be carried. With a Tankwell container, the amount of load that can go up to 26,5 tons.

What is the benefit of the lower tare weight of a Tankwell container?

The lower tare weight reduces the overall cost of transportation with 5%. A simple calculation example: a transporter who transports 450 tons per week over 1000 kilometers for 52 weeks a year.  This makes 18 trips per week and 936 trips per year when shipped by steel tank containers. Using a Tankwell container would save one trip per week (5%), adding up to 52 trips a year in total shipment savings. Also, 5% of fuel, time, insurance, maintenance, and cleaning costs are saved.

How to exploit the benefit of better insulation?

During the shipping of certain products in conventional stainless-steel tank containers, it is sometimes necessary to drive to a location to connect the tank container to a heating unit. It ensures the load is maintained at the desired temperature but delays the transport in general with 25%.

Due to Tankwells’ construction methodology, our tank containers are almost twice as well insulated as conventional steel tank containers. It means that they can remain the right temperature for 2 to 4 days longer, depending of course, on the outside temperature. This implies that additional heating is no longer necessary. In addition, it is not needed to equip the tank container with a heating unit.

Part of Tankwells’ additional services is to predict the temperature change of your freight using our developed models. This way, you can optimize your supply chain, minimize costs while reducing your CO2 emissions at the same time.

When was Tankwell founded?

Tankwell was founded in 2012, and the first containers where introduced in 2015. Our production facility is located in Wieringerwerf, north of Amsterdam, the Netherlands. Our game-changing development is the result of close collaboration between Composite Production Technology (CPT) and Flax Field Europe. Tankwell is a CPT Brand. Since 2015, well-known liquid transport companies have successfully been operated over 450 lightweight tank containers in both chemical and food supply chains.

Are Tankwell tank containers suitable for the same products as conventional stainless-steel tank containers?

Some shipped products in composite tanks cannot be carried in stainless steel tanks and vice versa. Here you can find an overview of our different types of containers. Please contact us if you require further information.

Are Tankwells' containers affected by pitting corrosion?

There are several products that, although they are not strongly acidic or strongly alkaline, can cause pitting corrosion. For example, calcium chloride, zinc chloride, aluminum chloride, magnesium chloride, and acidic fruit juices. These products provide additional maintenance for conventional steel tanks because they cause pitting corrosion. The transport of these products in traditional steel containers results in many extra maintenance costs, and sometimes even that tank containers have to be written off earlier. The Tankwell tank containers can transport all these products without any additional maintenance. It will save your company a lot of time and money.

Is it possible to transport products with a low flash point (<60°C) in a Tankwell composite tank container?

Yes, this is possible in our antistatic tank containers. For this version, the tank container is modified according to ADR, Ch. 6.9, to prevent electrostatic charges.

Is a Tankwell composite tank container's lifespan the same as a conventional steel tank container?

Yes, the design and the applied materials selected to achieve a lifespan comparable or longer than conventional steel tank containers if handled correctly and professionally.

Does a Tankwell lightweight tank container come with the same equipment as a steel tank container?

Yes, the equipment on Tankwell tank containers is the same, and interchangeable with commonly applied tank container equipment.

Is steam cleaning possible with Tankwell tank containers?

Yes, although the maximum service temperature is 70°C, higher temperatures can be applied in the cleaning process. Steam cleaning is possible.

Is it possible to repair Tankwell tank containers?

Yes. The composite can be repaired, applying recognized repair methods and principles for composite products. Typically, the repair cost is the same or lower compared to repairs of conventional stainless-steel tanks.

Are there any End of Life Options for composite material

Yes, although recycling is still in an early stage of development, there are several potential routes for glass reinforced plastics, such as cement kiln processing and incineration. Please refer to our sustainability page for more information
