Modular IndIrect FIred Bent tuBe Heater (IBt)
closed view
The Modular Indirect Fired Bent Tube Heater (Model IBT) is designed to deliver clean
air into an indoor environment. The push-through design of the unit ensures that
combustion fumes will not enter the fresh air stream being delivered into the space.
The standard unit includes a blower module and the indirect heater module with multiple options for discharge and
intake. Five housing sizes are available in our modular design with up to four furnaces available in one unit. The air
volume range is from 800 to 15,000 CFM and up to a maximum of 3 inches wg. for static pressure. The unit can
deliver a constant 83% efficiency over the entire gas-firing range.
