How the ESS MaxCharge™ Spray Nozzle Works |
The heart of the ESS sprayer system is the Max-Charge induction electrostatic nozzle.
The original induction charging air-assisted nozzle was invented by Dr. Ed Law at the University of Georgia.
ESS has made many improvements to Dr. Law's original concept; the result is a simple, safe, and reliable electrostatic spray nozzle system.
This new novel induction charging method has been found to be the best way to charge spray in dirty and dusty environments.
Induction charging can produce a very high charge without using high voltages. Other types of charging methods, such as contact charging, use voltages that are much too high to be safe or reliable in dirty environments.
 
ESS MaxCharge™ Spray Nozzle
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.

ESS manufactures many types of sprayers that are used in agricultural applications. 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.
The picture to the right is a magnified high-speed photograph showing charged spray droplets moving towards a leaf on the inside of a plant canopy. Charged spray is driven inside the plant cover by air and the charged droplets attract to all surfaces by strong electric fields between the droplets and the leaf. The result is a uniform coat on hidden areas.

| Many growers are seeing the benefits of ESS air-assisted electrostatic sprayers. If you grow cotton, peanuts, strawberries, potatoes, melons, onions, leafy vegetables, etc. we can make a sprayer for you. Benefits are a reduction in your chemical expense and better insect and disease control. The average payback is usually less than one growing season. |
