Sterymax STX-360ES Professional Cordless 360° Electrostatic Sprayer


- +

Our Whynter Sterymax electrostatic sprayer uses a patented technology to apply disinfectants in a whole new way. The Whynter Sterymax system is time saving, cost effective and most importantly potent and efficient.

The Whynter Sterymax 360 Professional Electrostatic Sprayer places a positive charge on the liquid twice, once before entering the nozzle, and again at the nozzle, resulting in the maximum volume of liquid being charged and sprayed at surfaces (most surfaces are either negative or neutral) allowing for a complete 360 degrees wraparound  coverage.


Time saving

The Whynter Sterymax Electrostatic Sprayer is superior to other disinfecting products such as wipes, foggers , or spray bottles  which are ineffective, time consuming or expensive.  Our Electrostatic System is 80% faster and uses 68% less chemicals than a conventional sprayer. That’s a significant increase in efficiency that will optimize time and cost.

Cost Effective

Save money by dramatically reducing labor and chemical costs. With the complete 360 degree wraparound coverage, the virus killing chemical is distributed evenly and economically which reduces the amount of over-spraying.

Performance & Efficiency

The Whynter Sterymax Electrostatic sprayer places a positive charge on the liquid before entering the nozzle allowing the maximum levels of liquid to be charged and sprayed at negatively charged surfaces (most surfaces are either negative or neutral). Electrostatic charged droplets create a field in the spray plume that is magnetically drawn to any surface within 6 feet allowing for complete 360 degree coverage of the targeted surface and object. The enveloping coverage is able to coat hidden and hard to reach surfaces that would likely be missed by conventional spraying or misting equipment.

Cordless & Portable

Designed for maximum flexibility, the Whynter Sterymax sprayer is light weight (only 3.8 lbs) and portable making it ideal for daily use in any situation or environment. The 4 hour run time and 1 hour battery charge time, delivers unmatched convenience for daily, facility-wide use.

Adaptable & Versatile

The 3-in-1 Nozzle (40/80/110 Microns) lets you set the spray particle size to match your application. It is easily adjusted to change droplet size, accommodating any requirement ensuring consistent performance and versatility.
