Ceramic Bobbin Heaters, 900 mm (approx 36""), 230 V

We SK Convection is manufacturing the ceramic bobbin heater is an electric heating element that uses a resistive wire coiled around high-temperature ceramic insulators, known as bobbins, to transfer heat. This construction allows for efficient and durable heating in industrial applications Applications Ceramic bobbins: The core of the heater is made from high-temperature ceramic materials, often cordierite porcelain, which provides excellent thermal and electrical insulation. These bobbins are stacked to create the desired heater length. Product Overview Heating element: A resistive wire, typically made from Nichrome (a nickel-chromium alloy), is wound around the ceramic bobbins. When an electrical current passes through the wire, it generates heat. Assembly: A center support rod is inserted through the bobbin assembly to provide structural integrity. Terminations: The ends of the resistance wire are connected to a terminal block for the power supply. Sheath (optional): For indirect heating applications, the ceramic element is often inserted into a protective metal tube or thermowell, commonly made of stainless steel or corrosion-resistant alloys Applications Indirect liquid heating: When inserted into a thermowell, they can heat liquids such as water, chemicals, oils, wax, and bitumen. Air and gas heating: The heaters can be used without a protective sheath to directly heat air and gases in ovens, furnaces, and ducts. Furnaces and kilns: Their high-temperature resistance makes them suitable for industrial ovens, heat treatment furnaces, and kilns for ceramics and glass manufacturing. Chemical processing: The chemical inertness and corrosion resistance of the ceramic make them suitable for heating chemical and salt baths. Automotive and electronics: Applications include automotive defrosting systems and in semiconductor manufacturing processes.
