Forced Hot Air Heater
Dragon Fire Hot Air Unit
The reliable, continuous heating source!
Industrial air heaters are designed to heat large working areas, structures and equipment effectively and economically with forced air heat in extreme cold conditions. The Dragon Fire Hot Air Unit can also be used in conjunction with other heating systems. Hot air units are mobile and provide an independent heating source for spot heating equipment. Units can be skid or trailer mounted and have dual fuel capability (oil/natural gas) with sizes ranging from 1.4 Mbtu/hr - 5 Mbtu/hr.
