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.

Self-adjusting burner profile plates allow for 2 speed and variable air volume applications. Plates ensure proper air velocity and pressure drop across the burner for clean combustion. 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.
