2.5 Million BTU Direct Fired Gas Heater

Model: HR2500
Large temporary makeup air heaters are the best way to warm large construction projects such as hospitals, schools and industrial processes. This 2,500,000 BTU heater has the ability to push warm air through hundreds of feet of duct or sit outside the desired space. The onboard power management system constantly monitors the voltage supplied to the heater. Construction projects are notorious for having fluctuating voltage. If voltage is too high or too low, the power management system will increase or decrease the source to the proper voltage to operate the equipment. No other rental heaters on the market have this capability. Mechanical contractors and facility managers love these makeup air heaters because of their ability to operate on 208-230 volts or 460 volt power. Truly a unique addition to a temporary heater. These direct-fired heaters usually sit outside of a building, but they do fit through a standard door frame.
