ENVIROMIST INDUSTRIES BACKGROUND
Based in Berri, South Australia, Enviromist
Industries is committed to the on-going development of safer, more reliable, cost effective
and accurate spraying technology.
and New Implement Award of Merit at the 1993
Australian National Field Days.
Based on the earlier success of the
Spraymiser®, subsequent generations of centre-row sprayers have been refined. The more
compact and manoeuvrable Spraydome®
2000 was developed during 1996, followed by
adjustable width versions early in 2000. These
popular new designs have now superseded
the original Spraymiser® design and are available in both towed and 3-point linkage configurations. A new generation of efficient, light,
low cost Spraymiser® centre row sprayers
have now been developed.
Enviromist’s development of new spraying
technology is based on objectives to lower the
volume and cost of chemicals used, to lower
the capital cost of equipment used, lower
operating costs and to extend the application
season allowing operators to spray during
conditions which could otherwise be prohibitive.
The original concept of “covered spraying” for
orchards and vineyards was initiated at South
Australia’s Loxton Research Centre during the
early 1980’s.
The popularity and success of Enviromist systems is confirmed by over 15,000 customers
world wide who have purchased sprayers over
the years. Usage extends to vineyard, farms,
orchards, plantations, golf courses, councils,
parks, gardens, woods and forest groups and
many others.
Enviromist Industries began in 1989 manufacturing a shrouded sprayer called the
Spraymiser® - a light, robust, trailed sprayer
for applying herbicide between rows in
orchards and vineyards. The unique design of
the Spraymiser® incorporated a variable
speed Controlled Droplet Applicator (CDA)
covered by a dome to prevent drift. The
Spraymiser® won “The Land” Machine of the
Year title and New Implement Award of Merit at
the 1990 Australian National Field Days.
Enviromist has a national dealer network and a
rapidly growing international market for its
products. Enviromist Industries currently
exports to France, Spain, USA, Canada,
United Kingdom, New Zealand, Middle East,
Argentina, Peru, South Africa and Chile. As a
consequence of our on-going commitment to
our expanding export markets, the company
won a South Australian Export Award in 1997
and in 2000, an Australia Post Australia Day
Award and a gold medal at Dionysud in
France.
In 1992 Enviromist released the Undavina® - a
circular, covered, vehicle mounted CDA
sprayer designed for use in vineyards and
orchards. The Undavina® won The Innovative
Horticultural Award and New Implement Award
of Merit at the 1992 Australian National Field
Days.
Common advantages of Enviromist’s technology reported by users include trouble free operation, significant savings in chemical, water,
fuel, labour, capital cost of equipment, reduced
soil compaction, more timely operations by
being able to spray even when conventional
sprayers cannot be used because of
unfavourable weather conditions.
The vehicle mounted Spraydome® 1000,
released in 1993, is specifically designed for
under vine or tree applications where the trunk
or stem of the young plant has to be protected
from herbicide contact. The Spraydome®
1000 won “The Land” Machine of the Year title

PRINCIPLES OF CDA TECHNOLOGY
The aim of CDA (Controlled Droplet Applicator)
technology is to produce all chemical solution
in a uniform droplet size that can be defined as
‘optimum’ for the target.
feed rate of liquid, the narrow spectrum of
droplet size can be altered to suit differing
applications.
To produce the narrow spectrum of droplets
desired it is necessary to understand the relationship between liquid flow rates and disc
speeds.
Unlike hydraulic nozzles which force liquid
under pressure through a small orifice to create
unstable sheets of liquid which break up into a
defined range of droplet sizes, the CDA technology is capable of producing very uniform
droplet sizes.
1. At low flow rates, large single drops are
produced. See illustration below.
The CDA uses a rotary disc instead of liquid
under pressure to produce droplets.
Liquid enters at the centre of a spinning disc
and propelled outwards to teeth on the outer
edge of the disc. The liquid is dispersed into
droplets through the teeth on the disc by centrifugal force.
The droplet pattern normally formed is a hollow
cone pattern, and is very uniform droplet size
which minimises driftable fines. A typical example of the narrow CDA droplet spectrum is
shown below.
Figure 1. Single Droplet Atomisation
PERCENT
2. As flow rate increases, single and ligamental atomisation occurs. The ligaments thin
down the point of emission and produce
smaller droplets. See illustration below.
DROPLET SIZE IN MICRONS
FLOW RATES AND DISC SPEEDS
CDA technology has the advantage that by
altering the rotational speed of the disc and/or

cont.
4. Further increasing the liquid flow rate will
flood the disc and teeth causing sheeting and
inconsistent droplet size. An uncontrollable
large spectrum of droplets result from flooding
a disc. See previous illustration.
3. As the liquid feed rate increases, all drops
are formed from ligamental atomisation. This
produces the optimum consistency of smaller
droplets. See illustration below.
Examples: Figures 5 & 6 show typical spray
test card samples from Enviromist Undavina
and Spraydome models.
Figure 5. Flow rate 15 litres (4 US Gal) per
hour travelling at 7 kph (4mph)
Figure 3. Ligamental Droplet Atomisation
For a tight control of drop size, the liquid feed
rate and disc speed should be adjusted to produce single droplets or droplets wholly formed
from ligaments.
A common fault of overfeeding a disc not only
produces massive wasteful drops, but also produces tiny satellite drops which can drift long
distances.
Figure 6. Flow rate 15 litres (4 US Gal) per
hour travelling at 10 kph (6mph)
Note: It is important to use the recommended feed
nozzles and power supply. Indiscriminate use of feed
nozzles and power supply can cause unsatisfactory
and damaging results. Always confer with your supplier or manufacturer before altering feed rates and
disc speeds.

ENVIROMIST CDA SPRAYING TECHNOLOGY
The patented technology used by
Enviromist Industries utilises the efficiency
and economy of Controlled Droplet
Applicators (CDA) while containing the
droplet cloud within a confined area using
a dome or cover.
The use of the shroud or shield minimises
drift, increases the effectiveness of the
CDA, and enables use in otherwise unacceptable wind, air temperature inversion
or thermal updraft conditions - when conventional spraying equipment could not
be used.
The CDA spray system uses a spinning
disc rotary atomiser to give optimum size,
evenly distributed spray droplets for maximum spraying efficiency. This allows ultra
low spray volumes to be used which minimises chemical wastage, environmental
contamination and operating down time.
Mounting on an ATV or small tractor
enables higher application speeds and
minimises labour and vehicle operating
costs.
Overall spraying cost savings of 50% to
75% have been reported by farmers using
this technology.

SAFETY INSTRUCTIONS
Always wear gloves and wash sprayer thoroughly before doing any disassembly or
repair work. If not, chemical residues on
machine parts could contaminate operator or
service personnel causing serious illness.
WARNING!
Read operator’s manual thoroughly before
operating Enviromist sprayers.
Always adjust sprayer to proper working
height, application rate and travel at an
appropriate speed to suit conditions.
Improper height adjustment, incorrect flow
rate and travelling too fast or slow will
adversely affect results.
Turn sprayer off before making adjustments
or repairs. Failure to do so could result in
injury or toxic chemical contamination and
serious illness.
Inspect hose and hose connections daily.
Damaged, loose or worn hoses will cause
sprayer malfunction, and may result in the
operator being exposed to toxic chemicals
Do not spray when air temperature exceeds
the maximum recommended by the chemical which could cause serious illness.

ness.
Always read chemical manufacturers’ labels
before using the chemical.
Remember chemical labels have been developed for your protection.
Be sure you recognise the categories of
chemical toxicity and their key words for
safety.
Wear appropriate protective clothing when
handling chemicals. Failure to do so could
result in serious illness or even death.
Always replace worn or damaged shroud
material on Enviromist sprayers. Failure to
keep shrouds in good condition may result in
off-target drift.
Always use the correct application rate.
Application rates of chemical which are too
high may expose the operator and environment to danger. Rates that are too low will
result in ineffective control.
Always follow the sprayer maintenance procedures outlined in this manual. Failure to
follow maintenance procedures will cause
malfunction and unnecessary repair work.
Dispose of all chemical containers as per
instruction on the chemical label. Failure to
do so could result in environmental contamination.

After the Tank and Sprayer(s) are fitted, proceed with connecting them to the backplate.
5. Connect the quick release hose coupling of
the tank hose (Fig.2, No. 4) to the connecter on
the backplate (Fig.2, No. 1).
6. Connect the 2 pin electrical plug (Fig.2, No. 3)
from the tank to the 2 pin socket (Fig.2, No. 2)
on the backplate.
7. To fit the sprayer control unit to the backplate,
first ensure that the inline switch (Fig.2, No. 5)
is in the OFF position. Connect the electrical
plug (Fig.2, No. 9) to a socket (Fig.2, No. 10)
while at the same time locating the clip on the
back of the control unit between the locating
lugs on the backplate.
8. Connect the quick release hose plug (Fig.2,
No. 7) of the control to the corresponding connector (Fig.2, No. 8) on the front of the backplate.
9. Turn all the control box switches (Fig.2, No. 11)
to the OFF position, and then turn the inline
switch (Fig.2, No. 5) ON.
10. Turn each control box ON and OFF in turn to
check that the power connection is effective
and that the pump is operating.
11. Visually check that the CDA disc under the
sprayer is spinning and that the lights are
glowing on the control unit.
12. Secure all hoses, ensuring that the operator
and moving parts are not obstructed.

ADJUSTMENTS TO APPLICATION RATES
Flow Rate. The flow is controlled in three ways.
Recommendations
1. The flow be left as the standard factory recommendation.
a) By the nozzles at the C.D.A. head,
the blue nozzle is the standard and is
recommended that it not be
changed.
b) Models of the CDA versions of 900,
600 and 400 series have an additional Restrictor Plate in the feed tube
to the control unit. It is also recommended that these not be changed.
c) The pressure from the pump may be
varied by opening (decreasing pressure) and closing (increasing pressure) the bypass valve (Fig. 6, No.1).
Before closing the valve and increasing the pressure there are three
things to consider:
i)
The CDA machines are
designed to work at 8-10psi
ii)
Closing the bypass will reduce
the agitation in the tank.
iii)
Increasing the pressure will
increase the flow rate and this
in turn will affect the size of the
droplets produced which
could also affect the efficiency
of the sprayer and the weed
kill.
2. Variation in ground speed may be
used to change application rates provided recommended top speeds are not
exceeded.
3. Variation of the chemical concentration is the easiest way to change the
amount of chemical being applied
once the ground speed and flow rate
have been established.
Chemical Mix
a) The higher the concentration of
chemical mix the higher the application rate.
b) The lower the concentration the lower
the application rate.
Ground Speed
a) Travelling faster than the calculated
speed will reduce the application
rate.
b) Travelling slower will increase the
application rate.
Note: Small variations up or down of 1-2kph
will not generally affect the result with
Enviromist equipment.

1.
Empty tank completely, observing all safety
precautions.
2.
Flush out with clean water and detergent, run
the sprayer to flush the lines and CDA for at
least two minutes.
NOTE: If for any reason it is suspected that water
has entered the motor housing, dismantle and dry
it, then give the motor a few drops of moisture
repellent before reassembling.
NOTE: For spray units with the Micromax® 120
head fitted to the rear, OIL THE HEAD ONCE OR
3.
TWICE DAILY (a few drops only). Do not over-oil.
Hose down the sprayer thoroughly, taking particular care to prevent water entering the clear
vent tube at the top of CDA head then allow
the CDA to spin dry by disconnecting the
water supply at the Back Plate connection.
At end of season maintenance, dismantle the head
completely, clean and dry the motor using some
moisture repellent and reassemble, remember to
use some waterproof grease under the top plate.
END OF SEASON MAINTENANCE
1.

Prior to storage drain the tank and flush the
sprayer as in the END OF DAY
MAINTENANCE.
2.
Allow the CDA heads to spin dry and completely drain all hoses, cover all the exposed
and unconnected ends to prevent contamination by grit and insects while in storage.
3.
The Spraydome® 1524, both towed and 3 pt.
Linkage should have their Control Units
wrapped in clean cloth and fastened safely to
the machine with the hoses rolled to avoid
damage.
4.
Ensure that when not in use, the Undavina®
and Spraydome® applicators are stored in
such a way as to give maximum protection to
the brush and dome materials.
Note: If Spraydomes® or Undavinas® are
stored, even for short periods of time, with
the weight of the machine or any other weight
on the cover or dome, permanent distortion
may occur.
Storage for prolonged periods in direct sunlight or areas of extreme heat should be
avoided.
The units should preferably be stored so that
they are supported in the same manner as
they are in their operating position. Refer to
the storage illustration.
The Spraydomes® should otherwise be hung on
