The most important criterion for the selection of RSM tanks is the capacity. The most popular variants are 20 m3 and 22 m3. Tanks of this capacity will allow all of the UAN to be taken from the tanker. However, it is worth noting that smaller capacities are also popular for use on smaller farms. The standard equipment of the tanks fully allows the use of fertiliser. However, in addition to this, it is worth retrofitting the tank with monitoring and liquid level alarm systems, which will increase safety and comfort of use.
