Item added to basket:
Duct heaters or electric air heaters are designed to act as reheaters in small branch ducts from a main air handling unit (AHU), or on systems where the supply fan is controlled from elsewhere. There is no fan run-on timer, so the heater relies on a volt-free or 230V start signal and stays off until airflow is detected by the combined DTFS airflow and temperature sensor.
