Etched Foil Polyester Heaters

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.

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.

 

Polyester Wire Wound Heater

 

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

Low watts per square inch

Distributed wattage

Edge loss compensation

Precise manufacture of very small heaters

Complex heat distribution

UL rating of about 105°C (221°F)

Economical mass production

Accurate reproduction of complex circuits.
