Liquid circuit UF – logical and convenient

The liquid circuit of the UF-series has been optimised as to operator friendliness and minimal residual volumes. Cleaning of the partly filled tank is possible as well as the targeted emptying of the suction- and pressure filter prior to opening the filter housing.

Electrically-controlled TG valve chest

For actuation using either ISOBUS or AMASPRAY+, modern valve chest technology is utilised. The part-width boom sections are switched, on and off, quickly and drip-free via electric motor valves with pressure relief. In all situations the spray rate is exactly and quickly controlled directly via the computer and so negating the need for any mechanical equal pressure control.

The DUS pressure recirculation system – proven more than 10,000 times

The AMAZONE DUS pressure recirculation system ensures a reliable circulation throughout the entire system. When starting the spraying operation all the hoses including the spray lines are filled under pressure in the reverse direction with the mixed spray agent. This means the spray lines are always full and immediately ready to use over the entire working width. There is no waiting on the headland. Every time individual part-width sections are shut off, during the turning operation and during transport, the spray liquid circulates continually thanks to the pressure recirculation system. This reliably prevents deposits, blockages or segregation in the spray lines. During the cleaning operation, fresh water flushes the spray lines out right up to the nozzles without any spraying being necessary. During this cleaning procedure the concentrated spray liquid is returned back to tank via the pressure recirculation system leaving the spray lines clean.

AmaSwitch individual nozzle switching for Super-S2 booms

If AmaSwitch is combined with GPS-Switch automatic headland and part-width Section Control, the individual nozzles are automatically switched in 50 cm part-width sections. The decisive benefit of this individual nozzle switching is the possibility to operate with small part-width sections even more precisely in wedge shaped areas, short work and on the headland. The amount of overlap is significantly reduced on the headland, for instance, by up to 85 % less when compared with conventional Section Control part-width section switching. In this way, depending on field shape, boom width and number of part-width sections, the combination of GPS-Switch and AmaSwitch results in considerable savings of spray agent compared with the usual crop protection techniques used up to now. The new technology is based on a 3-fold nozzle carrier with electric on/off nozzle switching. In addition to the automatic switching using 50 cm part-width sections, it is possible to configure the amount of part-width sections from choice. AmaSwitch is a cost-effective alternative for users who do not want to make electric nozzle changeover a priority but, however, want to make use of the advantages of the very precise switching in wedge shaped fields and overlap zones thanks to the 50 cm part-width section control. Standard equipment with AmaSwitch includes the DUS pro high pressure recirculation system. DUS pro prevents deposits in the spray lines and ensures an even spray agent concentration. Thanks to the pressure recirculation system all the nozzles are ready for operation over the entire boom width. In addition, when switching off individual part-width sections and when turning, the spray agent remains in constant circulation. In this way deposits, blockages and any potential demixing in the spray line is safely prevented. As a special option, AmaSwitch can also be supplied in combination with LED individual nozzle lighting.

WindControl - Calm conditions at the touch of a button

The effect of the wind on the spread pattern can be permanently monitored and automatically compensated for by WindControl. A high-frequency wind sensor mounted on the machine records both the wind speed and the wind direction and transmits this information to the job computer.
