Final answer:
A thermal fogger is the specialized equipment that uses heat to create a dry deodorant fog, often used in pest control and sanitation.
Step-by-step explanation:
The specialized equipment that utilizes heat to create a dry deodorant fog is called a thermal fogger. These devices are often used in pest control and sanitation operations to disperse deodorants, insecticides, and disinfectants in a fine mist. The thermal fogger heats a liquid solution until it vaporizes into a fog or smoke. This fog can then penetrate difficult-to-reach areas and is effective at neutralizing odors as well as eliminating pests and pathogens.
