Thermal ULV Fogging

Differences between thermo Fog & ULV fogging to disinfect and sanitise industrial property.

The difference between ULV and thermal fogging is the thermal generation process produces a smaller and more consistent droplet size. Thermal fogging produces a dry or damp fog as opposed to the wet ULV aerosol.

Although many thermal fogging devices are limited to applying only oil-based formulations, some thermal foggers are available that may also be utilized to apply water-based formulations.

  • The concentration of active material in thermal fogging is usually lower than in ULV applications.

  • Thermal fog droplets have better penetration and permeation properties than ULV droplets.

  • Thermal fog lends itself to the treatment of both large and small dwellings and buildings.

  • Gas-powered thermal foggers require no electrical source; no need to delay treatment if power is not available.

  • The small droplet size makes it possible to envelop contaminated atmospheres with odour counteractant, resulting in faster and more complete applications.

Thermal fogging devices

Thermal foggers are machines that utilize heat to change liquids into small droplets. These droplets condense when introduced into a cooler atmosphere. Thermal foggers can produce droplets as small as 0.5 microns up to 2 microns in size. Food grade Petroleum-based formulations are normally used with thermal fogging devices.

Disinfection of Aircraft


In March of 2020, we had concerns about the safety of our team at Air Center One. We wanted to know that they were confident coming into the centre and had a very real peace of mind over the Coronavirus outbreak that was taking place.

We had specific requirements of whoever was to perform the job; it had to last for 90 days to ensure ongoing safety and economy for the company.

Any product had to be approved by a recognised body to ensure quality and safety. It needed to cover the spectrum of current, developing and mutating viruses, with a particular emphasis on Coronavirus.

Virus Fog ticked all the boxes with an EPA approved product and a second compound that specifically targeted Coronavirus. We particularly liked the water based nature of the product that could be used on more delicate surfaces, and that it would last 90 days.

The efficiency and professionalism of the company also provided a great deal of confidence to all of us.

Our team feel secure in their work environment and I know we have taken the steps we need to take as responsible employees. It is important to us that our team go home safe and healthy.


We test before and after

"Successful hygiene intervention in the workplace reduces the spread of viruses on Fomites."

The number of sites with an ATP reading of greater than 2 RLU was 45% before the intervention and 15% after the intervention. This difference was shown to be statistically significant (p \ 0.005). Thus, ATP readings were useful in determining the success of the hygiene intervention as they demonstrated a significant reduction of the virus on the sampled fomites after the intervention. 

Discussion and Conclusions 

ATP bioluminescence is a general measurement of biological contamination. It does not directly monitor viruses but indicates a mixture of biological forms, such as human cellular materials, bacteria, and plant and fungal cells. Materials like epithelium from the upper respiratory tract mucus membranes, saliva, and associated material from the coughs and sneezes of persons with viral or bacterial infections can also contribute to ATP measurements. While there are limits to the use of ATP measurements in assessing the impact of cleaning practices, recent studies have demonstrated its potential usefulness for validating the effectiveness of cleaning practices in schools and hospitals. 

The rapid spread of the virus throughout the office after a high-touch surface (office door bar) or the hand of one employee was inoculated illustrates how a contaminated surface can result in viral transmission in the workplace. Shared facilities (e.g., break room, copy machine), where the transfer of viruses from infected to uninfected persons is most likely to occur, we're readily contaminated. The viral culture results show statistically significant reductions in the spread of virus (MS-2) from either a contaminated hand or fomites throughout an office environment after the implementation of hygiene interventions. This was accomplished with only 52% of the occupants of the building participating in the intervention, demonstrating that a significant reduction in virus spread can occur without everyone in the office following the intervention protocol. In addition, this improvement occurred after the intervention protocol was in place for only 3 days before the virus was seeded onto the hands/push plate. The seeding of the door handle or hand of an employee made no significant difference in the spread of the virus throughout the facility or the success of the intervention.

ATP measurements correlated significantly with reduced viral recovery and showed statistically significant differences in measurements taken before and after an intervention. This suggests that although ATP readings do not specifically predict the occurrence or degree of reduction in microbial contamination, the method can be useful for monitoring the success of health interventions in the workplace in terms of the reduction in the spread of a virus. 

Despite the described limitations of ATP measurement as a method for monitoring microbial contamination, the results of this study clearly demonstrate that workplace hygiene interventions can result in a significant reduction of viral contamination, and ATP can be used to monitor performance rapidly. It also illustrates that a general measure of cleanliness with a quantitative tool can be related to the spread of viruses in indoor environments and can be used as an aid to assess of potential interventions .


We get COVID-19 virus before it gets you.

Virus Fogging is a method of Disinfection & Sanitisation to control Pathogenic microbes along with fungi and different types of bacteria.

How does it do that?
A thermal fogger is a piece of specialised equipment that makes an Ultra Low Volume (ULV) mist with droplets of between 8-40 microns. The compounds we use are approved by the US EPA (Environmental Protection Agency) and register with the US FDA (Food and Drug Administration) some of these compounds are water-based dry in 60 to 90 minutes. The fogger makes a warm fine mist that settles and sticks to the surface killing the virus within 10 minutes with the process repeated every 30 to 45 days depending on the level of traffic in the area.

Microbial Control provides disinfectants 
for COVID19

With a severe virus spreading across the globe at a rapid pace and multiple governments declaring a state of emergency, virtually anyone can be infected.

The biggest issue is that medical researchers are still unsure how exactly these viruses can spread. One way we know it spreads is via droplets for speech and sneezing according to one Japanese study Microdroplets may play a part in the way corona-virus is spread. View here.

What is ULV Fogging and how does it work?

ULV Fogging works by compressing disinfectants through a custom-designed nozzle which produces a very fine cold mist. ULV Fogging equipment is used predominately for the application of disinfectants, biocides, fungicides and pesticides. The mist that is generated via the Fogger is in the form of Ultra Low Volume (ULV) droplets between 5-50 microns (μm) in diameter.

The droplets are projected into the air via the ULV Fogging unit and can #oat around for about 10 minutes after application reaching the most inaccessible parts where traditional methods of cleaning such as spray and wipe will not.

Why use Thermal Fog and how can you benefit? 

Thermal ULV Fogging has been used in China’s disinfecting program during the COVID-19 outbreak. It is a quick and simple way to disinfect large areas within minutes to prevent re-contamination. The area can be treated and re-occupied the following day with prior ventilation. Disinfection of surfaces using a Fogger is essential to prevent the spread of infectious diseases.
