Industrial Tubular heaters are highly adaptable to most applications where electrical heating is required. They can be used in their straight form or bent into various shapes. Tubular heaters can be used in free air, clamped to a surface, placed inside a groove or cast into metal. These versatile heating elements are available in

• steel,
• copper,
• stainless steel or
• Incoloy

outside sheath and can be utilized in application temperatures of up to 1400^º F.

INDUSTRIAL APPLICATIONS FOR STRAIGHT & FORMED TUBULAR HEATERS:

• FORMING MACHINES
• HEATING MOLDS & PLATENS
• IMMERSION INTO LIQUIDS
• RADIANT & CONVECTION HEATING
• EMBEDDED OR CAST INTO METAL

CONSTRUCTION:

Bucan tubular heaters use 80% Nickel 20% Chromium high grade coiled resistance wire as a heating core. This core is welded at both ends to pins that provide a cold section that varies in length depending on the application requirements. The coil-pin assembly is precisely centred inside a heavy gauge, oversize metal tube, and embedded inside a 96% pure, high-grade MgO insulating medium. This assembly is then compacted through a roll-reducing process that reduces the outside tube diameter to its final size, and transforms the MgO matrix into a rock-hard solid that acts as an excellent heat transferring medium, as well as an electric insulation with high dielectric strength. Finally, heaters are annealed inside a high-temperature furnace to eliminate internal stresses accumulated during the cold-forming and roll-reducing process to make them soft. Heating elements are then formed into special shapes, or supplied in their straight form. Proper electrical terminations are added to the final product.
