Thermal foggers, as the name suggests, are used for heating in the
fogging process. Thermal foggers use heat to dispense a fogging
solution and spray it out in the form of a dense fog. They are
equipped with a heat barrel that is preheated with high temperatures
using either a propane gas or electricity which depends on the type
of fogger. Every fogging solution exists in a liquid form, and when
pumped into the heated barrel, it vaporizes instantly. This process
allows the fogger to produce large amount of droplets in extremely
small sizes, which altogether forms a dense cloud of fog.
Thermal Foggers
Thermal foggers are classified into two types - gas and
electric. They are quite similar by the appearances, but in gas
fogger gas is used (generally propane) to preheat the heat
amalgamation, so a gas cylinder is needed to be mounted to the
fogger.
Electric foggers use electricity instead to heat the amalgamation, so
it needs an electrical cable that is plugged into an electric outlet
carefully. Foggers that use gas are usually fully portable and are
used in many places as it does not require an electric outlet or
cable for operation. Electric foggers are dependant on the length of
electric cables and supply but on the other hand gas foggers have
high operational expenses as their cylinders needs to be changed on a
regular basis.
ULV Foggers
ULV fogger is just opposite to that of a thermal fogger. A truck mounted ULV fogger also falls under a category of thermal fogger.
It is a cold fogger that basically operates using cold fogging
methods. To convert fog into minute droplets, foggers are intact with
motors that produce massive power, low pressure air fog. Similarly
like thermal foggers, the concentrate solution is stored into a tank
and when operation takes place the concentrate gets pumped out of the
storage.
Concentrated solution then gets sent into a specially designed nozzle
that is constructed in such a way to give the air flow a swirling
direction. A high air pressure produced by the motor of the fogger
helps to spray the concentrate liquid passing through the nozzle
separating it into tiny droplets. The liquid solution gets sprayed
out of the nozzle in form of a dense fog or a fine mist. ULV foggers
mostly depends on electricity, as it is needed to provide power to an
electrical motor. The particles sizes of an ULV fogger produced can
be adjusted to an output of precisely sized droplets, it allows the
fogger to be used for different applications. Also, as ULV foggers
use cold fogging methods and usually do not get heated under high
temperatures. They are used for both indoor and outdoor applications.
Thermal fogging and
ULV fogging both have their own importance for the purpose of indoor
and outdoor applications. Thermal fogging comprises majorly of indoor
purposes and ULV fogging for outdoor applications. Both fogging
techniques hold significant importance in pest control and are
efficient in their own ways. However proper handling and application
will yield to effective results.
