How the ESS MaxCharge™ Spray Nozzle Works

Air and liquid enter separately at the rear of the nozzle. The air moves at near-sonic speed through the nozzle and impacts the liquid at the tip.

This causes the formation of optimum size spray droplets of 30 to 40 microns in diameter. The air pressure needed is only 20 to 90 psi. At these low pressures the nozzles last a long time.

As the spray is atomized the liquid passes an electrode inside of the nozzle. Electrons are induced onto the liquid stream and the droplets leave the nozzle with a high negative charge.

The droplets are carried in an air stream towards the target. The closer the charged droplets get to the target, the stronger the electrostatic forces of attraction.

Charged droplets can travel long distances without losing their charge. The droplets follow electrical field lines of force and wrap around the target. Once droplets hit the target they immediately lose the electrical charge.

The MaxCharge™ nozzle design allows the use of many types of spray mixes, including heavy powders mixed in all types of liquids, and the nozzle is easy to disassemble for cleaning.

"It's that simple"

ESS manufactures many types of sprayers for agricultural applications as well as disinfection and other commercial applications. However, no matter what you are spraying, electrostatic means better spray coverage!

If you are a grower of any agricultural crop you should take a look at ESS technology to reduce costs, help the environment, and produce a better quality crop.

For disinfection and sanitization, an ESS electrostatic sprayer can deliver a consistent coating of the disinfectant chemical of choice and get the disinfectant into tiny cracks, crevasses, and hidden surfaces that would otherwise be missed. An ESS sprayer can prove its worth by minimizing human suffering and saving hours lost from work or school due to illness.
