Refractory Strip Heater
The Refractory Strip Heater’s highly compacted refractory material quickly conducts heat from the resistance wire to the sheath resulting in low internal temperatures and long heater life in the most demanding applications. Precise placement of the resistance wire provides uniform sheath temperature across the width and along the entire heated length. Terminal designs allow easy installation wiring. 3/8″ thickness creates a rigid sheath for secure clamping ability. The Refractory Strip Heater is ideally suited for many industrial and commercial applications.

Finned Refractory Strip Heaters
Finned Refractory Strip Heaters feature the same highly compressed, rugged design as Refractory Strip Heaters with the addition of 1-3/8″ X 2″ fins. Fins increase the heat transfer surface area to allow higher wattage’s than standard Refractory Strip Heaters. Rust resisting iron sheath items are standard with aluminized steel fins. Stainless steel sheath items are standard with stainless steel fins. Convection heating or processes requiring a high velocity air stream are among the many possible applications for Finned Refractory Strip Heaters.
