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.
