ULV Fogger vs Electrostatic Thermal Fogger

Updated: Nov 18



You may have heard terms such as fogging, misting, fogging machines, ULV foggers, electrostatic foggers or thermal foggers being thrown around when looking for a business to do your sanitizing. Should the type of fogging equipment they use influence your choice of who to use? YES. Let's find out why.


What is the difference between ULV Foggers and Electrostatic Thermal Foggers?


Each of these types of 'fogging' machines are designed to do different things and some sprayers have been re branded as sanitizing tools.


ULV Foggers


ULV fogger stands for Ultra Low Volume fogger. This refers to the amount of liquid disinfectant that is being sprayed.


These historically are mainly used for spraying fungicides, pesticides and biocides.


Droplet size from ULV foggers vary from model to model but they usually range from 20 microns to 50 microns in diameter and are sprayed out cold.


This results in less of a fog and more of a wet heavy mist.


The chemical being sprayed is still effective on surfaces but would leave them damp to the touch and take a considerable time to dry and could risk damaging fabrics, paperwork, electronics etc within the room being sanitized.


These are usually cheaper in cost and not as effective as other fogging machines.


See some examples of ULV foggers below.


Thermal Foggers


Thermal foggers are a much better option for sanitizing.


These thermal fogging machines (as the name indicates) super heats the chemical that is being sprayed.


This means that the droplet size can be reduced to as small as 0.5 microns to 10 microns by means of super heating and vaporizing the liquid. This means that the sanitizing chemical is now in a fog like state.


What is the benefit of this?


The smaller the particle size the the longer the sanitizing particles stay in the air and have more time to attach to and neutralize any airborne viruses.


Because of the super small particle size, the fog produced by a thermal fogger can reach into very small places such as floor gaps, cracks in walls and similar places indoors as well as other hard to reach places.



Also as the fog produced is dry it means that items such as electrical equipment, computers, TVs, remote controls, keyboards, screens and more can be safely sanitized using this method.


This type of fogging really does leave each room with a fog or visible haze for up to an hour after fogging has been completed and won't harm any surfaces such as fabrics or upholstery.



Electrostatic Foggers


Electrostatic foggers spray electrostatically charged fog/mist onto surfaces and objects.


The main reason for this being a great way of sanitizing is that objects and surfaces attract the disinfectant from an electrostatic sprayer!


Misters and ULV fogging systems deliver very small droplets that passively deposit on surfaces based on the direction of spray and the effect of gravity, which may result in uneven coverage.


Because all of the particles are charged as they are sprayed they are atomically drawn to the oppositely charged surface meaning that you get an even spray and therefore ensuring complete coverage.



What is the best fogging equipment to use?


Well clearly not a cheap ULV fogger.


So that leaves a choice between either a thermal fogger or an electrostatic fogger.


But what if you could have both in one!


WELL WE DO!


What Fogger do we use at Mist-IT?


We use only the best for our sanitizing and this is why we use the Fog Blaster Pro.


This is the latest in professional fogging equipment designed solely for providing the most effective and reliable sanitizing results.



Why use Fog Blaster?


Fog Blaster is an Electrostatic Thermal Fogger which is perfect as well as also adding Ozone into the jetstream for super effective sanitizing.


Key Benefits of the Fog Blaster

  • Nano Droplets (thermal)

  • Negatively Charged Ions (electrostatic)

  • Dry Fog (use on electronics)

  • Sanitizes Air & Surfaces (complete coverage)


Conclusion


When you are considering on which business you are going to use to do your fogging sanitization be sure to find out

  • which type of fogging equipment they are using

  • as well as quizzing them about the sanitizing chemical they are using

  • why they are using that chemical

If they can't answer these questions and are not using an electrostatic thermal fogger as well as using HOCL then you need to look at using us as the business to use.
