Etched Foil Silicone Rubber Heaters
The etched element provides superior heat transfer and exceptionally uniform heat output, resulting in a faster warm-up cycle and longer life. These flexible heaters operate in ambient temperatures from -80°F to 500°F.
Advantages over wire wound silicone rubber heaters:
- Higher watt densities
- Distributed wattages
- Greater element area over heater sheath
- Complex heat distribution with a rating of about 200°C (392°F)
- Economical mass production
- Reproduction of complex circuits
Wire Wound Silicone Rubber Heaters
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. Parallel circuits are utilized where possible, permitting continued operation should a single circuit be damaged.
Wire wound advantages over etched foil element:
- Faster turnaround time on prototype designs
- Lower engineering cost
- More economical pricing at lower quantities
Standard-sized, In-stock, Catalog Heaters
