Bobbin Heaters

Bobbin heaters are primarily used for direct air heating and indirect heating of liquids or gases. These elements are typically installed within a pocket or dry well inside tanks or process systems, allowing for easy replacement without the need to drain the vessel. This makes them a convenient and maintenance-friendly solution in industrial applications.

These heaters are highly energy-efficient, as nearly all of the generated heat is transferred directly into the medium. They are commonly used for heat transmission in a wide range of industries and are available in multiple specifications to meet varied application needs.

Bobbin heaters can be constructed with or without a protective sheath. Available sheath materials include stainless steel, nickel-plated mild steel, copper, and nickel-plated copper, depending on the application and environmental conditions. Inside, a resistance wire is wound and supported by high-temperature ceramic insulators, with terminals located at one end for electrical connections.

Constructed using ceramic link bobbins, these heaters can be configured for both single-phase and three-phase power supply. A thermowell can be integrated for precise temperature sensing, and additional control features can be added to suit specific operational requirements.

Bobbin heaters are typically designed for horizontal installation but can also be customized for vertical mounting. They are manufactured to operate at any required voltage or wattage within practical limits, with a focus on low watt density and lower temperature applications.

Known for their versatility, simplicity, and cost-effectiveness, bobbin heaters are one of the most widely used heating solutions across many industries. They offer an economical choice with easy installation and reliable performance.
