Electric duct heater for Ø400 mm circular ventilation ducts: 4 kW at 400 V three-phase.

It is built on a circular duct section that fits straight into the ductwork, and works as an electric heater battery for air heating in HVAC and ventilation systems.

The heating element is an open-coil wire element, which transfers heat directly to the airflow.

The RCF-SCTTC version includes a contactor and a bulb and capillary thermostat adjustable from -30 °C to +30 °C, mounted on the air inlet: once the switching temperature is set, the heater switches on automatically when it is reached.

Two thermal cut-outs, one with automatic reset and one with manual reset, trip if the airflow fails or is insufficient; the terminal block and cable glands are factory-fitted.
