Due to the new electronics a higher performance is ensured. The innovative and larger display allows an easy setup of the spray length, width and amount of precoating. The machine comes with four valves, which can be selected individually. This not only allows you to setup your individual precoating area but also saves a lot of precoating liquid.

The length of the spraying area can be regulated in 2 cm increments using the touch display. There are 10 levels available regarding the amount of precoating liquid. A specific feature of the device is the automatic cleaning process of the four spraying nozzles. This will prevent the nozzles from getting dry or blocked when the machine is switched on. All of these settings, can be stored in 5 different editable program buttons.


Cleaning process can be initiated with one touch only. The spraying nozzles can be removed without tools for ultrasonic cleaning.
