Direct Fired Module

Direct Gas-Fired Heater Module, for use in tempering make up air. Direct fired modular heaters are designed for natural or propane gas applications. Heaters are rated for indoor or outdoor installations in commercial occupancies. A unique feature is the self-adjusting burner profile plates allowing 2-speed and variable-air-volume applications. The plates ensure proper air velocity and pressure drop across the burner for clean combustion. Spring loaded profile plates react to the momentum of the fresh air stream, therefore, no motors or actuators are needed to drive them. Nor do they need to be manually set to a specific position.

Packages start at 1000 CFM and go up to 21,000 CFM, with external pressures up to 2" WG. Units have large doors on both sides to provide ample access to all internal components. Direct fired module consist of galvanized enclosure control panel and stainless steel burner.
