Open coil duct heater for Ø400 mm circular ducts, 4 kW 400 V three-phase, with contactor and thermostat - RCF-SCTTC

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: set the switching temperature and the heater switches on by itself when it is reached.

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