Ceramic Bobbin Heater
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.

Product Overview & Construction
High-quality components for superior performance
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.
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.
A center support rod is inserted through the bobbin assembly to provide structural integrity.
The ends of the resistance wire are connected to a terminal block for the power supply.
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 & Electronics
Applications include automotive defrosting systems and in semiconductor manufacturing processes.
