Overview of the ESS Model SC-EB Air-Assisted
Electrostatic Sprayer
Air-assisted electrostatic sprayers produce electrically charged spray
drops that are carried to the target in a low pressure, gentle, air stream.
The heart of the SC-EB Sprayer is the patented MaxCharge™ nozzle.
Air and liquid enter separately at the rear of the nozzle. Just before
leaving the nozzle, the air hits the liquid stream to make many thou-
sands of tiny spray droplets that pass through the charging ring. An
electrical charge is applied to the spray droplets by the charging ring.
Then the charged spray droplets are blown out of the nozzle and move
onto the target where they are attracted to surfaces by electrostatic
forces. The electrostatic charge induced by the MaxCharge™ nozzle is
strong enough to allow the droplets to move in any direction to cover
surfaces, even defying gravity to coat the underside of leaves and the
back side of the target objects. The result is uniform spray coverage
on hidden surfaces that other sprayers miss. Air-assisted electrostatic
sprayers give more than twice the deposition efficiency of hydrau-
lic sprayers and non-electrostatic types of air-assisted sprayers. The
grower benefits in terms of significant reductions in application costs
and optimized insect and disease control, sanitization of beef or other
coverage.
The MaxCharge™ nozzle is easy to clean and corrosion-proof. The inte-
rior ceramic outlet resists wear three times better than stainless steel
outlets. These features combine to give the best spray coverage on the
market. This quality product is virtually maintenance-free, and assures
you of savings in the application of chemical.
The comparison of air-assisted electrostatic spraying versus conven-
tional spraying is dramatic.
Electrostatically charged droplets are
attracted to plant surfaces.

Where Does the Spray Go?
A picture worth a thousand words…
In this test, fluorescent dye has been
sprayed on two round knobs. The left
knob was sprayed with the electrostatic
system ON; the right knob was sprayed
with the same sprayer, but with the elec-
trostatic system OFF. Note how even the
coverage is on the electrostatic knob.
The University of California completed a series of tests to investigate
what happens to spray liquid after it leaves the nozzle.
Conclusion: ESS technology places over 4 times the amount of
spray onto the plant surface using 1/2 the amount of chemicals.
Furthermore, they also reported that ESS sprayers send 2/3 less
chemicals to the ground and into the air. There is less waste, less
drift, and less chemical is used than with conventional sprayers.
Imagine the environmental benefit!
