EMist Used Worldwide
Industries using EMist electrostatic disinfectant sprayers to combat COVID-19 include aviation, education, facility management, government, healthcare, hospitality, retail, sports, and transportation. With such enormous square footage of surfaces in the world, efficient surface methods are needed for environmental disinfection. Prior to COVID, disinfection of surfaces was achieved through manual application of liquid disinfectants (spray bottles and wipes). This method has been shown to be labor intensive and uses about 75% more chemical as compared to alternate means.
Application of Disinfectants Using Electrostatic Sprayers
There has been increased application of disinfectants on List N via electrostatic sprayers given the need to disinfect large spaces to reduce the risk of exposure to the virus that causes COVID-19. Complete, comprehensive disinfectant surface coverage can be achieved using electrostatic sprayers.
How Electrostatic Sprayers Work
Electrostatic sprayers work by charging the liquid disinfectant as it passes through a nozzle. Per the EPA, positively charged disinfectant droplets are attracted to negatively charged environmental surfaces allowing for improved coverage on hard, non-porous environmental surfaces.
Electrostatic Sprayers: Technology Matters
It is important to note that most environmental surfaces have a negative or neutral charge (the earth itself is negative). As such, for true electrostatic adhesion to occur, electrostatic sprayers should impart a positive charge so that the positively charged disinfectant droplets are attracted to targeted negative or neutral surfaces. NOTE: EMist electrostatic disinfectant sprayers provide a positive charge to droplets.
The Expansion Cloud Effect explains how charged droplets are repelled by objects with a like charge. Coulomb’s Law describes that like charges repel each other while unlike charges attract each other. As droplets leave the electrostatic sprayer nozzle, they race to find their oppositely charged surfaces, this causes them to spread out and wrap around three-dimensional objects. Just as the automobile painting industry discovered decades ago, using an electrostatic sprayer results in an even coating. This includes hard-to-reach areas typically not touched by manual application.
Droplet Size Matters
Droplet size is a critical factor. Droplets must be large enough to resist evaporation and drift but small enough that the droplets can change their trajectory when it comes close to an oppositely charged target. Most electrostatic nozzles produce droplets of less than < 40 microns (categorized as Very Fine). Such small droplets increase drift and pose a user safety concern per the EPA. Droplets of < 40 microns have a low terminal velocity causing them to fall slowly. This makes them highly drift-prone, decreasing the results of electrostatic adhesion and increasing user inhalation concerns. NOTE: EMist electrostatic disinfectant sprayers produce an average 75 micron droplet size.
