Constant Fan Terminal Units
Model AC
The Carnes Model AC Constant Volume (Series Flow) fan terminals are designed for commercial HVAC applications that require accurate temperature control and constant airflow to the conditioned space. The internal fan runs continuous in the occupied mode. Controls modulate the damper to provide the proper amount of blending between the primary air and the warm floor plenum air. Hot water or electric heating coils may be added to provide additional heat if required. Constant Volume fan powered terminals typically serve the perimeter zones the may require heat while the interior zones demand cooling. Significant operating savings are gained through the recovery of floor plenum heat and the reduced central fan horsepower requirements.
Model ACWH - With Hot Water Reheat
Model ACEH - With Electric Reheat
Model AC (Low Profile)
The Carnes Model AC Constant Volume (Series Flow) Low Profile Design offers the same features & benefits as the standard design. The AC is ideal in applications where restricted ceiling plenums exist.
Model ACWH - With Hot Water Reheat
Model ACEH - With Electric Reheat
Model AC (Underfloor)
The Carnes Model AC Constant Volume (Series Flow) Underfloor Design is structurally identical to the Low Profile Design. Underfloor Fan Powered units are available in RIGHT HAND ONLY.
Model ACWH - With Hot Water Reheat
Model ACEH - With Electric Reheat
Model AC (Quiet)
The Carnes Model AC Constant Volume (Series Flow) Quiet Design is designed for noise sensitive applications such as offices, theaters, schools, and libraries. The constant volume fan runs continuously in the occupied mode, providing constant background sound to the space. The primary air damper operates in the same manner as a standard throttling unit, except that all of the primary air is sent through the inline (series) fan. Integral sound baffles and isolated motor mounting ensure low sound levels throughout the airflow range.
