BAC

ALL BIRDWELL BAC MODELS are available with optional components to serve various needs and application requirements. An air supply plenum eliminates ductwork and offers 3-way air throw from diffusers, each having vanes that adjust vertically and horizontally. A built-in control panel, with locking hinged door, eliminates the need for a separately mounted room thermostat.

If the unit is ordered with the air supply plenum and built-in thermostat, the only field work necessary for operation is mounting the unit and connecting to the power source, providing the outdoor location of the condensate drain meets the local building code.

Factory-installed options provide a range of heating capacities and application flexibility while reducing installation cost.
