Bobbin & Pipe Heaters are specialized industrial heaters designed for indirect heating of liquids, semi-solids, and gases. These heaters use high-purity ceramic bobbins with wound resistance wire, enclosed in metallic immersion tubes for safe and efficient heat transfer.
Their modular design allows easy replacement of bobbin elements, while optional thermowells and sensors enable precise temperature control. Widely used in chemical, food, and laboratory industries, they offer durability, efficiency, and flexibility in demanding applications.
