Watlow Thick Film Heaters
High Performance Conduction Heating Elements
Watlow Cable Heaters. The Watlow Thick Film Conduction Heaters are ideal for use in many applications where fast response and uniformity are essential. These high performance heaters use thick film technology on 14 gauge, 430 stainless steel to provide maximum temperature response in a compact package.

A clamp-on thick film heater provides the best possible combination of heat transfer, thermal efficiency and temperature uniformity. For example, clamping the thick film conduction heater on to a 316 stainless steel pan or aluminum griddle in foodservice applications results in uniform cooking and heating.

This technology can be applied in areas where space is at a premium or where conventional heaters cannot be used because of limited voltage and wattage combinations.

Thick film conduction heaters provide an low-profile heater in a variety of shapes. These shapes include two-dimensional circular, rectangular and square forms. Due to the direct surface contact, thick film heaters ensure greater heat transfer through thermally stable substrates and precise heater patterns.

FEATURES & BENEFITS:
  • 550°C (1025°F) Maximum Substrate Temperature - (dependent upon application demands and substrate material) Allows for high process temperatures than most conduction heater technologies.
  • UR File #E52951 CSA Available - Consult factory for current status of agency recognitions. Also conforms with applicable CE directives.
  • High Watt Densities for Clamp-on Applications - Allows for precise, repeatable wattage distribution and uniform temperature distribution.
  • Threaded Stud Termination - Produces strong, trouble-free connections.
