Fax-Back Data Sheet

Polyester heaters are used to heat large areas very economically. These heaters can be designed and fabricated in many types of configurations to fit the size and shape required in your application. They have many uses in medical equipment, restaurant equipment, warming batteries or deicing. The maximum surface temperature for the polyester heater is 105° C (221° F).Polyester heaters are used to heat large areas very economically.

  • Long life
  • High reliability
  • Economical in large sizes
  • Versatile configurations

Etched Foil
The etched element has superior heat transfer and exceptionally uniform heat output, which results in a faster warm-up cycle and longer life. Use this heater to cover large areas with even heat, for flat or gently curved surfaces. Polyester is UL recognized with 105° C (221° F) surface temperature in the application.The etched element has superior heat transfer and exceptionally uniform heat output, which results in a faster warm-up cycle and longer life.

Etched foil polyester heaters can be designed and fabricated in many types of configurations to fit the size and shape required in your application.

Due to the resistance limits of the foil materials, as circuits become larger the economics of foil versus resistance wire become less attractive.

Our designers use a custom computer-aided design program to calculate the design, given the voltage, wattage and resistance.

Advantages of the etched foil versus wire wound heating elements are:

  • Low wattage sq/in
  • Distributed wattage
  • Edge loss compensation
  • Very small sizes of heaters can be precisely manufactured
  • Complex heat distribution with a rating of about 105°C (221°F)
  • Economical mass production
  • Accurate reproduction of complex circuits

Reliable Heating Elements
Here in the Hi-Heat manufacturing facility, fine nickel-chromium alloy wire is spiraled onto a center core of fiberglass twine to produce a strong, flexible element. Our proprietary winding equipment is electronically controlled to assure consistency. Post-production inspections assure quality and accuracy.

Circuits are hand-wound on tooling patterns custom-designed for the appropriate resistance. Parallel circuits are utilized as possible, permitting continued operation should a single circuit be damaged.

The precision wound resistance element is then positioned between two layers of polyester. Vulcanization permanently encapsulates the wire.

The polyester heaters are characterized by the following:

  • Excellent electrical properties
  • High thermal durability
  • Low moisture absorption
  • Low shrinkage
  • Exceptional cut-through resistance
  • Ability to perform in humid or moisture-laden environments
  • Easy application with adhesives
  • Lower cost than silicone
