Thermal & UVL Fogging
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. Petroleum-based formulations are normally used with thermal
fogging devices.
UVL foggers are wet foggers that produce smaller droplets than wet foggers/ misters.
ULVs can be adjusted to generate particles in the 8-15 micron size range.
Droplets can stay suspended in air for five or six hours instead of a few minutes with a wet fogger/
mister.
Electrostatic Sprayers
Electrostatic spray surface cleaning is the process of spraying an electrostatically charged mist onto
surfaces and objects.
Electrostatic spray uses a specialized solution that is combined with air and
atomized by an electrode inside the sprayer. Subsequently, the spray contains positively charged
particles that are able to aggressively adhere to surfaces and objects.
Because the particles in the spray
are positively charged, they cling to and coat any surface they’re aimed at.
For most disinfectants to work, a targeted surface must be completely coated and remain wet for up to
10 minutes. Plus, all targeted surfaces need to be disinfected correctly – not just “high-touch” areas.
Fine Misting/Fogging Whole Room Systems:
Whole room fine misting/fogging, delivering products such as hydrogen peroxide.
Devices are wheeled
into the room which is then sealed off while the unit fills the room with a fine mist of hydrogen
peroxide.
This equipment delivers a one micro droplet sized mist into the enclosed space. This process involves
filling the enclosed room with this fine fog, which may take several hours.
People and animals cannot be
present during the application.
With this process, the hydrogen peroxide mist will reach all areas of the room, areas that conventional
‘spray & wipe’ protocols may miss (electrostatic spraying only impacts surfaces they are directed to).
