Indirect oil-fired portable heaters

Allmand Bros. offers a line of indirect oil-fired portable heaters designed to provide heated air that is free of moisture and contaminants. With three models that operate on only 120 volts and range in capacity from 320,000 to 505,000 Btu, the Allmand indirect-fired heaters are designed for construction, mining, aviation, agricultural and municipal applications. Equipped with an industrial-grade power burner that is powered by a ¼-hp motor, the heaters deliver between 2,500 to 3,100 cfm, and a 200-and 220-degree F discharge temperature at 50 F. A heavy-duty heat exchanger serves as a barrier to the flame and allows fumes and combustion products to be vented through a flue stack and away from the heated area.
