Southeast Thermal Systems offers designs of heating elements that are either wire wound or etched foil, depending on the application and the heater’s requirements. Our products are Silicone Rubber, Polyester Film, Kapton® Polyimide, High Temperature Mica, Ceramic and Enclosure Heaters. We manufacture drop-in subassemblies with sensors, thermostats, fuses, cords and plugs. A combination of insulating materials is used.Southeast Thermal Systems offers designs of heating elements that are either wire wound or etched foil, depending on the application and the heater’s requirements.

Our heater products warm batteries in telecommunications cabinets, dry the ink in silk screening machines, cure the film on airplane windshields, heat laboratory samples, or maintain an animal's body heat during veterinary operations, to name just a few applications.

Flexible Heaters
Selection of silicon rubber etch foil heaters, silicon rubber wire-wound heaters, Kapton® heaters, as well as drum and pail heaters area.Type W flanged can also be attached to Fig. U unheated section on stock items.
Surface Temperature versus Time for Silicone Rubber Heaters
Illustrated is the surface temperature of a standard Silicone Rubber Heater, .055" thick without insulation at several watt densities. The heater is suspended vertically in 70°F (20°C) still air.
Maximum Watt Density

Etched foil elements can be designed at higher watt densities based upon application considerations. Consult or contact STS.

Thickness of Optional Silicone Sponge Insulation:
1/8", 1/4", or 1/2"
Thickness of Optional Foil Backing:
0.005" (0.13mm).

Dimension Tolerances:
Less than 6 " (150mm); ±.03" (± .8mm);
6 - 12 " (150mm - 305mm); ±.06" (±1.5mm);
12 - 36 " (305mm - 915mm); ±.12" (±3.5mm);
Over 36 " (915mm); ±1%

The area where leads are attached adds additional thickness depending upon gauge wire used and type.


12" leads are standard. Gauge of wire to be determined based on amperage or other considerations.

Composite Bonding Processes and other applications may require special heat pattern or uniformity. Heat Mapping Certification is available as an option. Underwriter's Laboratory and CSA recognition or listing apply to most configurations
