Vine sprayer
The ZEBRA is available in a configuration with spouts for spraying vines.
The spouts can be easily orientated, so that efficient air and spray mist
are applied on both sides of the vine plant.
Applying the precise dose is easily chosen by the manifold valves and
pressure regulator.
Whenever mixing of spray liquid is done during transport, the turbine
fan can be disengaged.
The spray boom has a total width of 4.5 meters, and it can be adjusted
0.5 meters in height.
Pneumatic system
The pneumatic system operates on low pressure and produces a high air
speed in the spout to break up the spray film and create a very fine
turbulent mist. Via the atomizers in the spout, the mist is distributed
uniformly in the shape of a fan.
Four types of spouts are available depending on boom type:
A. Cannon with 1 outlet
B. Spout with 2 outlets
C. Spout with 3 outlets
D. Spout with 4 outlets
Ceramic discs are used to control the flow rate. This disc has two
positions. If the disc is placed so the flow enters through its flat side, this will allow less to go through than if it enters through
the cone-shaped side.
Hydro-pneumatic system
The hydro-pneumatic system operates on a medium to high pressure.
This system takes advantage of the great amount of turbulence in the
cone-shaped low-volume nozzle and distributes the spray liquid
correctly. The air gets to the spout at high speed and this spreads the
water in the shape of a fan.
There are two types of spout, with three or five nozzles. These two
spouts cannot be used together.
E. Spout with 3 nozzles
F. Spout with 5 nozzles
