The thermal fogger is the polar opposite of the cold fogger. They're also known as ULV (ultra-low volume) foggers since they don't utilise heat to evaporate the fogging liquid, instead opting for the cold spraying approach, which in most cases employs air pressure to spray the liquid out in minute particles.
