Standard Cable Heaters

 
Zesta Watlow Standard Cable Heaters
Zesta Watlow Standard Cable Heaters
The versatile Watlow cable heater can be formed to a variety of shapes as dictated by its many applications.  Cable heaters are small diameter, high performance units, fully annealed and readily bent to a multitude of configurations.

The heater can be formed into a compact coiled nozzle heater for use on plastic injection molding equipment supplying a full 360 degrees of heat with optional distributed wattage. A straight cable can snake through a sealing bar in packaging equipment. Flat spiral configurations are used in semicon- ductor manufacturing while a star wound cable is used for air and gas heating.

Different applications require different construction methods, including one, two, three 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 sheaths. Whatever the application, the Watlow cable heater can be shaped to fit your application needs.
