Operating Limits
The following things are important when considering the performance of the sprayer.
• Maximum driving speed
• Pressure setting
• Minimum / maximum volume rate
The operating limits for your sprayer are closely related to:
9. Pump size
10. Boom width
11. Nozzle size
In the table below, the operating limits for volume rate are calculated, when driving at different speeds.
÷
NOTE! The specified nozzle type is a standard flat fan nozzle. Other special nozzle types will show different results. Ask
your HARDI dealer if in doubt.
μ
ATTENTION! It is recommended not to drive faster than 16 km/h when spraying.
μ
ATTENTION! The pressure range for the nozzles are 1.5 - 5 bar (except for HARDI INJET nozzles, which are ranging from
3-8 bar). The spraying pressure should be within these limits.
μ
ATTENTION! In the table below, the specified combination of nozzle size and sprayer setup is not suitable, as the full
pressure range of 5 bar for the nozzle cannot be reached, when spraying the maximum volume rate (l/ha) on the crop.
This is due to the nozzle design.
÷
According to the standard for environmental requirements for sprayers, ISO 16119 / EC Directive 2009/127/EC
(amending 2006/42/EC), the farmer shall be able to use the full pressure range.
