What is electrostatic spraying and how does it work?

IMD uses the latest electrostatic sprayers utilizing advanced technology to apply disinfecting solutions. They’re based on the principle that opposite electrical charges attract. If you take the “positive” end of a magnet and put it against the “negative” end of another magnet, they attract and stick. If you put the positive ends of two magnets together, however, they repel each other. An electrostatic sprayer is a device that electrically charges disinfectant, giving the solution a positive charge. Electrostatic sprayers use this principle to ensure fast, even coverage of the disinfecting agent. As the solution is combined with air and atomized by an electrode inside the sprayer it exits with a positive charge. The solution is attracted to and evenly covers all (negative and neutral) exposed surfaces uniformly and evenly. Surfaces that are already covered will force the solution to spread out, making it the fastest, most efficient and cost effective way to disinfect. Hard to reach three dimensional areas like desks, floors, walls, doors, and any equipment are covered without over wetting like conventional sprayers. Conventional sprayers only utilize the initial force coming out of the sprayer and gravity to achieve coverage, achieving inferior coverage that is also wasteful and causes pooling of the solution which can cause damage to surfaces and electrical equipment. Electrostatic technology allows IMD Disinfection to provide the fastest, most economical disinfection for our customers.

Features and Benefits of electrostatic spraying versus conventional spraying include

  • Faster more effective coverage of all surfaces and hard-to-reach places compared to conventional methods
  • Perfect coverage for all touch point coverage including handrails, elevator buttons, door knobs and push bars
  • Ionized mist bonds to surfaces with tight clearances such as computer keyboards, registers, appliances, and manufacturing equipment
  • Touch less application which reduces cross contamination of all surfaces
  • Applies chemicals in a more efficient, controlled manner, eliminating the dangers of over wetting/damage to surfaces and equipment
  • Effectively covers more area in less time using less solution which lowers operating costs for us and cost of service to our customers

Comparison chart of the choices for disinfection technology is shown below. As a baseline, hand spraying/aerosol application has an even wetter footprint, longer dwell time, costs more in terms of solution used and labor to apply, suffers from the lowest coverage and consistent application, and is the most damaging to all forms of equipment (personal, office, electrical, and manufacturing).

Using electrostatic technology IMD enables farmers to utilize natural soil, synthetic medium, or hydroponic systems and maximize yields while eliminating mold/mildew/rot on their crops. It enables farmers to apply specific grow cycle (growth/flower/flush) nutrients to all above-ground growth (including undersides of leaves). There is no better way to feed and protect your investment.

Simply stated, the advantages of electrostatic spraying versus all other application methods put it into a class by itself which is why IMD Disinfection chooses to utilize this method.
