TDA

Exhaust unit with presence detection

Airflow activated by presence detection

The TDA exhaust units directly adjust the extracted airflow to the level of human presence detected in the room. The airflow level in “presence” mode can be adjusted at every moment according to the usual number of occupants in the room (1 to 4 persons per vent). When the room is unoccupied, the airflow is automatically reduced, allowing on average, savings of 50% on thermal losses due to ventilation. The TDA exhaust unit is particularly well suited for installation in offices or small meeting rooms. A relay version also enables the lights or other equipment to be switched on and off via infra-red sensor.
