Urea tanks tailored to your needs
A urea tank for a tractor or a combine ranges from 40 to 200 litres, depending on the engine power and the required autonomy. Certain rules have to be respected to install the inserts, the gauge system and the filling with its filter. The particularity of the liquid used to trap the NOX particles – urea – is that it is very fluid, corrosive with certain alloys, and crystallizes when cold.
All of this means that we need to provide tanks with air volumes that allow the expansion of the urea to be contained and allow the tank to be filled and maintained. For tractors and other agricultural machinery, rotomoulded urea tanks are a perfect solution, because they can be designed to your needs.
Best material choice
To avoid chemical reactions between urea and certain dyes, only polymers colored by compounding are safe. The temperatures of use remain compatible with these materials, i.e. around 70°C maximum.
Components that may come into contact with urea must be resistant. Stainless steel is particularly suitable for metal parts, while certain seals must be designed to offer the best behavior over time.
A high value in assembly parts
A urea tank is equipped with several systems. The filling system must be equipped with a special filter and must prevent overfilling. The caps are sealed to prevent loss of urea through this orifice. The gauge system is made more complex by the addition of a resistance or liquid heating process, and suction and return pipes.
To ensure the efficiency of the pollution control system, these gauges are equipped with electronic components to send urea consumption data back to the dashboard. Sometimes they use sensors to measure the quality of the urea in the tank. Finally, it must always be possible to drain the tank.
For all these specific components, we have developed a real expertise and have a network of suppliers able to offer the best technological solutions to manufacturers of agricultural machinery. As with all our tanks, we check for leaks, visual appearance and dimensions before delivering them to our customers.
