Thermal Foggers vs. Cold Foggers
All throughout 2020, we've heard nothing but news about disinfectants, sanitizers, Covid, and
even the different companies trying their best to support us. Various companies are
producing excellent products and disinfectants to help people out, and now it is up to the
general public to choose the appropriate disinfectants and sanitizers and keep everything
sanitized and clean.
With the pandemic outbreak, many new ways to sanitize and disinfect have emerged, making
it confusing which product is actually effective, what the differences are between them, and
how they work.
Here, we will highlight and explain two products that have become more mainstream and
used by many industries and companies of all sizes. The products are the thermal fogger and
the cold fogger.
The Difference Between the Thermal
Fogger and the Cold Fogger
The thermal fogger, as its name states, uses heat to vaporize the fogging solution it contains.
Thermal foggers have a tank for storage that can hold about 1.2 litres to around 10 litres of
solution. The thermal fogger machine has a pump that is used to send the solution from the
container through the heating assembly located on the front part of the fogger.
The fog that is created by the thermal fogger can be quite dense fog but is extremely useful in
penetrating the hard-to-reach areas and surfaces. The heat also takes the moisture away
from the disinfectant, so the application is dry. The micron size is quite small which allows
the disinfectant to be airborne eliminating pathogens in the air as well as fully covering the
The cold fogger is just the opposite of the thermal fogger. Also called ULV (ultra-low
volume) foggers, they do not use heat to vaporize the fogging liquid but instead use the
method of cold spraying, which in the majority of the cases uses the air pressure to spray the
liquid out in the small particles. They produce fog using pressure in one of two ways: either
the solution is pumped through a high-pres
