Concept: spray varied at nozzle level

The SPRAYTRONIC is a device that allows you to vary the flow of the mixture while preserving the pressure and thus the size of the droplets.

Depending on the forward speed, a solenoid valve on each nozzle disperses the spray. The ratio between the opening and closing time varies depending on the speed variation at a fixed frequency. Simply put, the nozzle opens and closes 20 times per second. The variation in the flow of the spray is accomplished by varying the opening time within an opening/closing cycle. It’s works on an easy-to-use principle: the user simply selects the nozzle to be used, the operating pressure and the volume per hectare.

SPRAYTRONIC thus makes it possible to vary the flow of a nozzle by 70%, and consequently the working speed, without changing the operating pressure.   

The pulsating spray nozzles also stand out from other models by opening the way for flow cut-offs and for nozzle-by-nozzle modulation.
