The Duct Air Heater 9kW 315mm Three Phase is ideal for commercial ventilation systems requiring higher power heating. It supports both supply and extract fans and includes combined temperature and airflow sensors for precise control.
Equipped with solid-state switching, this heater avoids mechanical breakdowns, while control status indicators simplify monitoring. Safety is ensured with a high-temperature limit and manual reset, and separate supply and extract outputs allow reliable operation for duct heaters over 150mm diameter, providing a robust solution for demanding commercial applications.
