Dual Duct Terminal Unit with Hot and Cold Inlet, Integral Attenuator, and Mixing Chamber
Krueger’s dual duct terminals are designed to maintain optimal temperature control in the conditioned zone by varying the air volume supplied by the hot and cold supply ducts while providing the proper discharge air temperature. Dual duct terminals can also be used in fresh air applications where ventilation air must be monitored. One inlet can be a dedicated ventilation inlet. A wide variety of pressure independent pneumatic, analog, and factory mounted direct digital controls are available for variable or constant volume applications.

The model LMHDT is designed for those specific applications where temperature control is critical. This unit features an integral attenuator and hot/cold airstream mixing chamber for precise discharge temperature control. The LMHDT performs with a 20:1 air temperature mixing ratio in most conditions.

Hot and cold airstreams are controlled by inlet airflow sensing for variable volume control or a combination of inlet airflow sensing and discharge sensing for constant volume control with pneumatic, analog, or direct digital control arrangements.
