Product Details
Flexible Polyester Heater
Etched Foil Polyester Heaters
The etched foil element has superior heat transfer and
exceptionally uniform heat output, resulting in a faster warm-up
cycle and longer life. Use this polyester heating element on flat
or gently curved surfaces to cover large areas with even heat.
Due to the resistance limits of the foil materials, as circuits
become larger, the economics of foil versus resistance wire become
less attractive.
Wire Wound Polyester Heaters
Wire wound polyester heaters offer the capabilities of an etched
foil heater without the strict size limitation. A fine
nickel-chromium alloy wire is spiraled onto a center core of
fiberglass producing a strong, flexible heating element.
Electronically-controlled precision winding equipment ensures
consistency. Circuits are then hand-wound on permanent tooling,
providing repeatability of resistance and pattern.
