Nozzle Sets for Typical Spraying Applications
The nozzle sets in the following four examples are suitable for typical applications when spraying
grapes, orchard fruits at either low or high spraying volume, or citrus fruits.
1. Grapes
Application rate 600 l/ha
Travel speed 5 km/hr
Row width 3.0 m
Spraying pressure 15 Bar

Jet/Swirl Plate Size Closed Closed 1.0/CC 1.0/CC 1.0/CC 1.0/CC 1.0/CC Closed
To provide a substantially horizontal spray pattern to suit vines the jets in positions 1, 2 and 8 are
closed by flipping the nozzles through 90 degrees so that neither of the jets is facing outwards,
refer diagram on page 14.
The fitment of the same sized 1.0 jet and Closed Centre swirl plate (CC) in each of the nozzle
positions from 3 to 7 will produce a uniform density within the spray pattern. An alternative nozzle
arrangement would be to use HCC02 (Orange) in positions 3-7 at 11 bar pressure.
2. Orchard Fruits - Low Volume Spraying
Application rate 1000 l/ha
Travel speed 5 km/hr
Row width 6.1 m
Spraying pressure 20 Bar
1000 x 5 x 6.1 = 51 l/min
600
This arrangement will produce a spray pattern with approximately 70% of the output discharging from
the four centre jets Nos. 3, 4, 5 and 6. Refer to the Standard Jet Set Chart on page 17 for details of
the output from each nozzle combination of disc and swirl plate at various pressures. An alternative
nozzle setup using HCC Hollow cone would be as below with pressure at 16 bar.
