TC-320 Electrostatic Sprayer System

With Induction Charging Nozzle Technology

It is not just what is applied but how a coating is applied that matters most It’s all about coverage Electrostatics provides better coverage Better coverage saves time and money

Electrostatic Spraying

• Electrostatic sprayers apply an electrical charge to a

coating material as it is sprayed through the nozzle.

• The charged droplets are attracted to the spray target and are able to wrap around objects, and even overcome gravity, giving a thorough, even coating.

What Is Electrostatic Spraying?

• When a coating material is applied electrostatically it

prevents excess run-off with no loss of coating material. The most effective way to disinfect an area Able to apply coatings to areas normally not reachable

by normal spraying techniques No wiping down Coatings dry within seconds Saves money Cuts down labor time Uses coating material more efficiently

Why Do I Need It?

Remediation and Restoration • Mold and Mildew removal and prevention Disinfecting and Sanitizing • Restrooms, athletic facilities, health clubs • MRSA outbreak prevention • Bio-hazard Meth lab & Crime scene Clean-up Medical • Improved infection control for patients and staff

Coverage Comparison

Three sheets of white construction paper follow. Each sheet is sprayed with black ink using one of three sprayer types, a pump or common sprayer, a trigger sprayer and an electrostatic applicator. Each sheet was weighed before and after spraying to determine the amount of ink applied. Look carefully, any visible white paper represents an area where the sprayer failed to apply the coating (ink) to the surface.

Where Does Coating Material Go?

The University of California completed a series of tests to investigate what happens to spray liquid after it leaves the nozzle.

Conclusion: Electrostatic technology places over 4 times the amount of coating onto target surfaces using ½ the amount of solution. Microbecide® electrostatic sprayers send 2/3 less solution to the ground and into the air. Less solution used overall, less waste than conventional equipment. Improved operator productivity and significant cost savings!

Coating material savings alone make electrostatic sprayers a smart investment. For most applications, the cost of sprayer is earned back in less than six months.

Reduces coating usage by 70%

Fewer number of passes. More square feet of surface per hour. Less hauling and re-filling of coatings. Less clean-up because coating goes where you want it.

Reduces labor up to 70%

How does the TC-320 electrostatic sprayer system achieve this

remarkable coverage?

Air is necessary in electrostatic spraying to break the liquid into tiny droplets, and push the charged spray toward

complex surfaces.

Air-Assist

The force of electrostatic attraction is stronger when the droplet size is small and the charge to the droplet is high. The optimum size droplet for electrostatics (40 micron) is created when the high speed air, impacts the liquid inside the nozzle.

Electrostatic Sprayer: particles with the same electrostatic charge repel each other, keeping them equally spaced.

Conventional Sprayers: uncharged particles are attracted to each other other, forming even larger droplets.

Droplet Size

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

Electrically Charged Droplets

Electrically Charged Droplets

Electrostatics have been used for years in various industries to apply paint evenly and completely, this anti-gravity feature is commonly referred to as the “wrap-around effect”.

With the electrostatics turned OFF, the sphere is sprayed for four seconds.

Using a new sphere, this time we turn the electrostatics ON, and spray for two seconds or half the time of the first spray (representing 50% reduction of material).

We sprayed the PLASTIC waste can for 3 seconds with full flow rate (240ml/min). The target (waste can) was approximately 1.0 metre from the nozzle. The front image is the side of the waste can that was sprayed directly (facing the nozzle). The back image is the back side of the waste can that was not exposed to the spray steam. Note the complete coating accomplished by the “wrap around” effect of the electrostatics!
