Flagro THC-175DF Ductable Direct Fired Tent Heater 175000 Btu/h

Product Description

The FLAGRO THC-175DF is a ductable, direct-fired forced-air heater rated at 175,000 BTU/h with a maximum blower output of 1,200 CFM. It operates on dual fuel liquid propane or natural gas and converts between the two without special tools. The unit runs on 115 volts, 1-phase, 60 Hz and draws up to 15 amps. Thermostatically controlled operation maintains consistent heat output across large temporary spaces. The cast-iron burner, igniter, and flame-sensor assembly are all field-serviceable. Licensed HVAC technicians, gas-appliance technicians, construction site supervisors, and rental fleet operators are the primary users of this equipment.

The THC-175DF is designed for large tent events, construction enclosures, industrial work areas, and other temporary structures requiring high-output forced-air heat. Its ductable box-style configuration accepts flex or rigid duct transition components for directed airflow distribution. The unit suits both short-duration event heating and extended job-site use where a permanent heating plant is unavailable. Propane fuel consumption runs approximately 8 pounds per hour at full fire. Natural gas consumption is approximately 175 cubic feet per hour.
