Coil and Cable Heaters

Detail The versatile Watlow coil/cable heater can be formed into a variety of shapes. 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, including one, two or four resistance wires; parallel coil or straight wire; drawn or swaged sheaths; with or without internal thermocouples; leads exiting from one or both ends, and round, rectangular or square cable cross sectionals.
  Whatever the application, the Watlow coil heater and cable heater can be shaped to fit.
Features & Benefits High ductility allows the heater to be cold-formed into almost any shape
  Low mass allows for quick response in both heating and cooling
  Capable of operating in unusual environments, including cryogenic and sub-freezing temperatures, high vacuum, gaseous and liquid immersion heaters
  240V maximum voltage
  Durable construction materials for high-temperature corrosion and oxidation resistance along with ideal expansion properties
