ESS Electrostatic Sprayers

Electrostatic Sprayer Systems (ESS) use electrostatic technology to give superior spray coverage. At the tip of the ESS nozzle is a tiny electrode which applies an electrical charge to the spray. This electrical charging causes a natural force attraction between the spray droplets and target surface, similar to the attraction between items of clothing created by the tumbling of a clothes dryer.

The electrically charged droplets have a force 75 times greater than the force of gravity that reverses their direction and move them upwards, against gravity, when passing a target surface. This remarkable phenomenon by which the spray coats the undersides and the backsides of the spray target is known as electrostatic “wraparound.” In practical terms, this means that spray not only reaches the back and underneath side of the target but infiltrates the nooks and crevasses of the target surface.

The air-assisted electrostatic sprayer systems produce spray droplets which are 900 times smaller than average. The tiny droplets are blown toward the spray target in a high-speed air stream which results in more than twice the deposition efficiency of other non-electrostatic air-assisted sprayers.

Spray coverage is the uniformity of spray droplets on target surfaces. Electrostatic sprayers achieve greater spray coverage by combining air turbulence with tiny, evenly-sized spray droplets.
