Introduction 9
Micron Sprayers Ltd. Spraydome/Undavina and Spraymiser
1 INTRODUCTION
The Spraydome/Undavina/Spraymiser is designed for the precision application of
sprays. The spray heads are shielded to protect spray from drift. The shielded spray
heads incorporate either low volume rotary atomisers for controlled droplet
application (CDA) or traditional hydraulic pressure nozzles. The shielded spray heads
are designed primarily for the application of herbicides in beds. The shielded spray
heads can also be used to apply non selective herbicides in the crop inter-row or
around trees at reduced dose rates and volumes as only a proportion of the area is
treaded.
The Undavina and Spraydome sprayers are mounted on a breakaway arm which
allows the shield to rotate on a centre bearing and roll around tree or bush crops.

recommendation.
Tank washings and rinsate should always be sprayed out onto either the
treated crop (do not exceed maximum dose rates) or onto a
designated area.
Avoid run off into ditches or waterways at all times.

18 Safety
Micron Sprayers Ltd. Spraydome/Undavina and Spraymiser
2.4.1 Drift Reduction Measures
The Spraydome/Undavina/Spraymiser units are fitted with shields low to the ground
making them far less susceptible to spray drift than unshielded spray nozzles.
Wind tunnel studies in the UK have indicated drift reductions in excess of 90% over
conventional unshielded sprayers and the Enviro range of covered spray shields are
suitable as a Drift Reducing Technology (DRT)
Below are UK star ratings for drift reduction with the Undavina, Spraydome and
Spraymiser. LERAP (Local Environmental Risk Assessment for Pesticides)
Note: The maximum drift reduction of >75% receives 3 star rating.
Equipment Nozzle/disc Flow rate or pressure Star rating
Spraymiser HiFlo Teejet XR-04 2.0 bar ***
Spraymiser CDA Disc 150 – 300 ml/min ***
Undavina CDA Disc 100 – 300 ml/min ***
Undavina HiFlo Fulljet FL-5VC 2.0 bar ***
Spraydome HiFlo Teejet XR 04 2.0 bar ***
Spraydome CDA Disc 150 – 300 ml/min ***
Table 1 – LERAP Drift reduction rating (2 m/sec wind speed)
Spray heads must always maintain close contact with the ground. When operating
on uneven or rough ground reduce speed to ensure the spray heads do not bounce.
The following measures may be used to further reduce any risk of spray drift.
Schedule treatment for the early morning or the evening hours (there is generally
less wind).
With the Hi Flo units avoid spraying at pressures above 30 psi (2 bar) where
possible.
Keep the working height of the spray heads as low as possible. The risk of drifting
increases as the distance between the shield and ground increases.
Avoid operating at excessive speeds and flow rates.

Installation 19
Micron Sprayers Ltd. Spraydome/Undavina and Spraymiser
3 INSTALLATION
Notes for CDA Installation
The Spraydome/Undavina/Spraymiser CDA Controller has been designed to be
integrated into your tank and spray pump systems. The controller backplate will be
connected to your spray pump and control the on/off operation of the pump. Your
tank system should be regulated to an output pressure of 8 to 10 psi. Your tank
system must include an inline filter of 50 mesh size (blue – ISO19732).
Notes for Hi-Flo Installation
The Hi-Flo spray heads are fitted with traditional hydraulic pressure nozzles and will
easily integrate with most tank systems. Output rates for traditional hydraulic
pressure nozzles depend upon the size of the nozzle and the spray line pressure.
Ensure that your spray tank and pump system are capable of maintaining the
required output flow rate and pressure. Micron Hi-Flo systems will normally operate
at between 1 and 2 bar (15 to 30 psi). Your tank system must include an inline filter
of 50 mesh size (blue – ISO19732).
