The spectrum line of electrostatic ground sprayers built by Sides Inc. are used in orchards and nurseries throughout North America, while the Spectrum electrostatic backpack spray system is proven to improve control of mosquitoes and other disease vectors.

How electrostatic attraction works

Spectrum electrostatic spray systems employ the same principals of physics used by auto body paint shops and photocopy machines to assign a positive or negative electrical charge to the spray droplets as they pass through the spray nozzle.

Unlike conventional spray droplets, which contain an equal number of positively charged protons and negatively charged electrons, spray droplets emitted through a Spectrum electrostatic system receive a positive or negative charge from electrodes surrounding each nozzle. As the charged spray droplets approach the target vegetation, they induce an opposite charge on leaf and stem surfaces, thus activating electrostatic forces and attracting the charged droplets to both the upper and under leaf surfaces.

Spectrum Electrostatic improves spray performance

Up to 100% improvement in spray deposition (droplets/cm2)
Increased chemical deposition on target surfaces,

including shaded undersides of leaves

Reduced spray fallout, run-off and off-site drift
Improved control of insects, diseases, weeds and brush

… reduces operating costs

As much as 66% increase in area treated per hour/day
Up to 66% less water required per spray tank
Less tank refilling “down time”
As much as 66% reduction in labor and fuel requirements

… and enhances environmental/human safety

Up to 82% reduction in worker exposure to chemicals
Reduced environmental pollution
Reduced engine exhaust emission/greenhouse gases
More marketable service attractive to retailers/consumers
Concerned about pesticide use and environmental quality
