Extract unit with presence detection

Detecting presence in an office environment

TDA extract units directly adapt the extracted airflow to the 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 terminal). When the room is unoccupied, the airflow is automatically reduced, allowing savings of 50% average on thermal losses due to ventilation. The TDA fan is particulary adapted to offices or small meeting rooms. A Relay version enables to engage the light or other equipments which can be enslaved to presence.
