A tubular heater consists of a spiral-wound resistive wire perfectly centered in a tubular metal sheath filled with a powdery insulator (electro-fused magnesia).

Laminating the resistance allows compacting the magnesia, necessary to obtain good thermal conductivity and excellent mechanical and dielectric strength.

The extremities are sealed with a resin (silicone, epoxy, polyurethane, etc., according to the application) and then, terminated by a ceramic plug. The electric connections and the mechanical attachment accessories can be offered upon request.
