UAN flexible tanks

testuje se additional info

The Exflo “Farmer type U” tank is designed to provide secure storage of mineral liquid fertilizers such as UAN. It is constructed using a special, durable material and production technology, enabling the Exflo Farmer UAN flexible tank to be set up on almost any level ground.


With a lifespan of over 10 years, investing in this tank is a wise choice. The quick assembly and delivery of the Exflo tank will help to create a warehouse for liquid mineral fertilizer within days of ordering. Our Exflo service team can assist you in the initial setup of the tank.


As experts in environmental protection and substance storage, we recommend placing the tank in an additional membrane. We have prepared an attractive price for such a set, to ensure that safety doesn’t come at a high cost.

Advantages – tanks for UAN / ASL

Product dedicated to the agricultural industry: Liquid fertilizer tanks (UAN) have been designed to be able to store specific liquid fertilizers, such as UAN, which are used in agriculture.
10-year warranty: The tanks are covered by a 10-year warranty.
UV resistance: The PVC fabric is protected with a special varnish, which extends its life during exposure to UV radiation.
Cold resistance: The tanks are resistant to negative temperatures: down to -30°C.
Safe technology: A special and resistant membrane allows for the secure storage of liquid fertilizers in accordance with the requirements of Council Directive 91/676 / EEC of 12 December 1991 (the so-called "Nitrates Directive")

Technical data

  • The standard capacity of Exflo flexible tanks for nitrate fertilization is from 20 to 265 m³.
  • Material: Polyester fabric, PVC coated on both sides and lacquered, UV resistant finish; cadmium free. Weight: 1300g / sqm. Tensile strength: 4400N / 5cm
  • Chemical resistance: Suitable for the storage of liquid fertilizers with a pH value of 3-10 with an alcohol content of <4%;
  • Air vent with the possibility of connecting to the filling: thread 2″
  • Filling-draw-off connection: 3-inch threaded. 1 piece as standard. Possibility to install additional connections almost anywhere in the tank.
  • Suction and pressure line – available as an accessory.
  • Optionally, a collecting membrane is available as a second tank jacket.
  • Resistant to UV and weather conditions, covered by a 7-year warranty

The tank has high weather and tensile resistance thanks to the use of advanced and robust lacquered and PVC-coated technical fabric. It can be folded and moved many times without losing its properties. Contrary to popular fears, polymer fabrics are not ‘thin films’. They are specially designed and the internal reinforcement can withstand heavy loads.  

Caution should also be exercised with sharp objects, as used with sufficient force they can damage the surface and the core of the fabric. 

The specific weight of the fabric is 1300 g/m² and the tensile strength is 4300 N/5 cm. Moreover, the material can withstand temperatures from -30°C to +70°C making it resistant to changing weather conditions. The tank is guaranteed for 10 years and has a technical lifetime of up to several decades, depending on use and insolation.

UAN Tanks – Sustainable Agriculture and Environmental Protection

UAN tanks are key to sustainable agricultural development. These modern solutions minimize the negative environmental impact by efficiently storing and distributing liquid mineral fertilizers containing nitrogen in a form that is easily absorbed by plants. Thanks to precise fertilizer dosing, UAN tanks help reduce the risk of over-fertilization, which can lead to water and soil contamination.

UAN Tanks and Innovative Storage Solutions

The use of modern technologies in the production of UAN tanks guarantees higher quality and safety of the stored substances. With the application of durable materials such as certified carbon steel with anti-corrosion protection, as well as specialized coatings resistant to the effects of UAN, our tanks become highly resistant to weather conditions and mechanical damage.

UAN Tanks as Support for Farmers

As a tank manufacturer, we design UAN tanks with the needs of modern agriculture in mind. Easy installation and operation, along with availability in various capacities, make them incredibly functional and tailored to specific agricultural requirements. The ability to quickly and safely refill sprayers without the use of ladders is just one example of their practical value.

UAN Tanks Customized to Individual Needs

With the possibility of personalizing UAN tanks according to the user’s needs, every farmer can find the ideal solution for their farm. Whether you need a small tank with a capacity of 1,500 liters or a large one reaching up to 22,000 liters, customization to specific requirements is easy and available.
