Coil and Cable Heaters

Coil Cable HeatersCoil and Cable Heaters are small diameter, high-performance units, fully annealed and readily bent to a multitude of configurations. The cable heater can be formed into a compact, coiled nozzle heater supplying a full 360 degrees of heat with optional distributed wattage. A straight cable heater can snake through an equipment application. Flat spiral configurations can be used in high-tech manufacturing while a star wound cable can be used for air and gas heating. Different applications require different construction methods.

Coil Heater

Coil Heaters​

Coil Heaters are used in operations involving heating of cylindrical-shaped surfaces for temperatures up to 1800°F (982°C) where precise temperature control is essential. The design incorporates a built-in thermocouple, with a grounded junction terminating at the end of the cable opposite to the lead end. The built-in thermocouple and the overall low mass construction provide quick response for positive temperature control.

Cable Heater

Cable Heaters​

Bulk Round Heater Cable can be formed into many configurations, making it suitable for many applications including its extensive use in heat tracing. The heat source is a resistance wire in straight or coiled form. A swaging and drawing process compacts the ceramic insulators that house the heating element into a solid mass, producing a rugged and durable heater cable with excellent thermal conductivity and dielectric strength.

Minimum bending radius for all mineral insulated cable heaters is two times the sheath diameter.
