| 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. |
- Manufactured by Watlow
- Continuous operating temper-atures to 1200°F (650°C) with intermittent operating periods achieving up to 1500°F (815°C). Dependant on type of element wire used
- Sheath watt densities on the cable to 30 W/in 2 (4.65 W/cm 2 ), and as high as 75 W/in 2 (11.62 W/cm 2 ) within factory approved conditions
- High ductility allows the heater to be cold-formed into almost any shape
- The heater's low mass allows for quick response to both heating and cooling
