The portable ExThermonator flameless heater is designed to eliminate bed bugs quickly and efficiently using dry, clean and breathable hot air. For a typical residential treatment, the complete operation — including setup and teardown takes less than four hours, the company says. Designed to generate huge volumes of air instantaneously and capable of penetrating large spaces evenly, the ExThermonator can be used for a broad range of applications, both residential and commercial. Its heater pumps air so powerfully (easily over 400 feet) that for most treatments the unit remains on the truck. For the few occasions it is needed, however, the unit fits easily through doorways and elevators.
