Sheathed band heaters are comprised of a tubular heating element shaped according to the diameter of the part to be heated and held in place by an external clamping band which acts as a reflector.
Waterproof and robust, these band heaters are particularly suitable for harsh conditions (vibration, humidity, dripping water, etc.) up to a maximum heating temperature of 450 °C.
They can be connected to the power supply by threaded terminals or cables.
Sheathed band heaters can be manufactured in one or several parts and equipped with a thermocouple fixed to the clamping plate.
