Difference Between Electrostatic Sprayers and Other Sprayers

Apr 23, 2020

When Carrying Out Chemical Disinfection of an Area, Why Are Electrostatic Sprayers More Effective at Delivering Better Chemical Cover & Protection Than Traditional Sprayers.

 

Electrostatic sprayers deliver their chemical disinfectant solution more comprehensively, more efficiently and much faster with less waste, therefore saving time and money while delivering a pathogen free and greener environment.

Electrostatic disinfecting technology is superior to any other method of disinfecting.

Misters, fogging systems and manual trigger sprayers deliver very small droplets that passively deposit on surfaces based on the direction of spray and the effect of gravity. This results in uneven coverage of disinfectant, which can mean leaving harmful pathogens remaining on surfaces.

And spray/wipe methods are time consuming, labour intensive and disinfecting is only as good as the person wiping these surfaces.

What are electrostatic sprayers, and how do you use them

Electrostatic spraying is essentially a method of applying a complete coating of a  cleaner, or chemical disinfectant, or other liquid. It involves applying an electric charge within the sprayer to the chemical disinfectant liquid in order to get it to fully cover any surface it is sprayed at. 

The result is a more cost and time efficient process with numerous advantages. It is worth understanding how electrostatic spraying actually works and why it is the best and most advantageous disinfection and sanitisation method to use to get the most out of your cleaning protocols and processes.

How Electrostatic Spraying Works For Chemical Disinfection and Decontamination.

The basics of electrostatic spraying are as follows. The primary principle is to apply a positive charge to the chemical disinfectant or liquid being applied and to ground or negatively charge the surface being coated. 

Using the scientific principle that opposite charges attract each other, the positive charged liquid would then be attracted to the grounded or negative surface, allowing for a full, even coat of chemical disinfectant on the surface.

This proven concept is combined with the process of atomisation. By internally applying an electrostatic charge to the liquid within the sprayer, each water/chemical particle becomes charged with the same positive charge.

Using the same principle that opposites attract and similar charges repel each other, the chemical disinfectant particles are naturally repelled by one another, and freely break apart or atomize. This is the primary concept that allows for a more even coating of the chemical disinfectant on all surfaces in the path of the disinfectant spray.

 

Advantages of Electrostatic Spraying

Electrostatic spraying of chemical disinfectants has numerous advantages over using conventional electric powered or hand powered sprayers and other disinfecting application methods.

The biggest advantage being, the electrostatic charge applied gives a more even, full coat of protection when compared to other methods. When the positively charged chemical disinfectant is sprayed onto a negatively charged (grounded) surface, the disinfectant particles are naturally and strongly attracted and stick to the surface. 

As the entire surface being sprayed is negatively charged, the entire surface will be covered by the chemical disinfectant, leading to uniform coverage and overall a more comprehensive protection from pathogens or from cross contamination by touch. 

Another very useful advantage of using electrostatic spraying to disinfect or decontaminate an area is that it can get to hard-to-reach areas, like crevices, around corners, and backsides of surfaces. The airborne disinfectant will “seek out” uncoated surfaces to adhere to rather than already coated material, as the attraction is stronger to the uncoated surfaces. This comes in handy as electrostatic spraying can reach areas that could not otherwise be reached with traditional sprayers.

CHARGE 1

When the unit is turned on charge starts at charging ring and works itself back down the line, through the pump and into the tank changing all ions positive.

CHARGE 2

All the positive Ions from the tank are pumped from the tank through the pump and charged again at the charging ring all prior to becoming atomized.

Why Electrostatic Sprayers are Better Than Conventional Sprayers

Conventional sprayers use a mechanical atomization method, where air pressure is used to break down the particles of disinfectant. This leads to a higher forward spraying velocity, and in turn there can be splatter or overspray. This doesn’t happen with electrostatic spraying since air pressure is not used in the atomization process.

When you look at common surfaces, such as walls, floors, and fixtures, they are naturally grounded, meaning they have a negative charge. So if a liquid chemical disinfectant is positively charged, as it is in an electrostatic sprayer, this liquid will fully coat almost any surface it is sprayed onto. 

Electrostatic spraying lends itself particularly well in the areas of disinfecting and restroom cleaning. In restrooms, virtually any surface can be a hotspot for bacteria and odors to grow. In cracks, under toilets and urinals, on the walls, and many more that we probably don’t even think of when we are cleaning. 

By using an electrostatic sprayer system, all of these surfaces can be coated with a cleaner or disinfectant, and the restroom will be much more efficient and completely cleaned. Probably the most useful cleaning method that is being utilised with electrostatic spraying is disinfection and decontamination from pathogens. 

When you think about the concept and process of disinfecting, electrostatic spraying is a perfect pair with it. You need to fully coat a surface and leave it wet for the recommended contact time, most often 10 minutes. 

Electrostatic spraying can help with both of these issues, and is much more effective than mop-and-bucket, spray-and-wipe, or cloth-and-bucket applications. A big issue with disinfectants, regardless of the method of application, is ensuring that all surfaces are disinfected, meaning that disinfectant needs to be applied to all surfaces. 

This can become a problem when it comes to hard-to-reach areas or larger areas. Often we don’t have the time or diligence to cover every surface in a room; we can miss surfaces like walls, undersides of tables, counters, and desks, and many more. Many cleaning professionals are trained to disinfect the “high-touch” surfaces, as they are most important. 

Electrostatic spraying eliminates the need to limit ourselves to only the most soiled surfaces. We can spray every surface in the room, fully disinfecting it, and saving a lot of time in the process. We can be assured that even those hard-to-reach areas are disinfected. 

This is a big deal in facilities where disinfection is paramount, like hospitals and schools. It also offers promise in controlling foodborne illnesses in restaurant or food processing facilities.

Another component of disinfecting is obtaining the necessary contact time with disinfectants. For most disinfectants, this means ensuring the surface remains wet for 10 minutes. This is a big issue especially in spray-and-wipe disinfecting. In many instances, we spray a surface down and wipe it almost immediately. 

This is not ensuring a 10- minute contact or dwell time; in fact, it is ensuring we don’t get a 10-minute contact time. A common rule of thumb used in the cleaning industry is that if we leave the surface visibly wet and let it air dry, we can assure we have achieved the proper 10-minute contact time. 

Electrostatic spraying can solve this issue as it can be a “set and forget” type of application. For instance, in a restroom/toilet, after it has been cleaned, we can simply spray the entire room with our disinfectant and leave it to air dry. Once the disinfectant has dried and the restroom is opened up, it has been fully and properly disinfected. Electrostatic spraying can make the disinfection process much easier, more effective, and more cost efficient.

One concern with using electrostatic sprayer delivery methods is whether it will affect disinfecting efficacy. It is important to ensure that the disinfectant you are using with the sprayer is compatible, otherwise you may not actually be doing any disinfecting at all. The main class of disinfectants use an active ingredient called quaternary ammonium chloride, or “quat.” Since quat is a naturally positively-charged particle, it makes sense that this ingredient would be compatible with an electrostatic sprayer. Still, testing should be done with each disinfectant (or sanitizer) with a particular brand/model of electrostatic sprayer

At Infection Prevention Ireland we use a chemical disinfectant which is specifically designed to work seamlessly with 100% compatibility with our electrostatic sprayers. Our Victory Electrostatic sprayers are the leading technology in cordless electrostatic spraying. This combination delivers maximum results when carrying out any disinfection and sanitising procedures in any type of premises, in any industry, including, nursing and care homes, office environments, leisure and beauty industry, retail, food manufacturing, hotels and the restaurant and entertainment industries. Veterinary and animal husbandry. Fire and rescue services, ambulance services. Policing and prison services.

Lastly, here is a question we are regularly asked, “do organisations carry out their own electrostatic spraying”? The simple answer is yes. Many organisations purchased their own electrostatic sprayers and have their own cleaning staff trained in how to use them. Training usually takes half a day with instructions on how and when to spray. How to add water to the disinfectant concentrate and how to methodically disinfect an area leaving it fully disinfected and safe for use by other staff and customers, service users and clients. The chemical disinfectant is food safe, it’s human and animal friendly, with no solvents or any ingredients harmful to humans. PPE is not needed when using the sprayers with our chemical disinfectants. Utilising existing cleaning staff to electrostatically disinfect the workplace or business premises can be very cost efficient. The savings do mount up when using our cleaning protocol in conjunction with our equipment and chemicals. On average, savings of 65% on cleaning products and a cleaning time reduced by as much as 70% are savings which are commonly achieved. 

Then, when you add the cost savings achieved through the reduction of absenteeism of staff due to viral illnesses,  it does not take long to work out that electrostatic sprayers being used with the right chemical disinfectants can amount to substantial savings for any organisation.
