  • Summary

The coiled resistance wire is embedded in a special refractory Material that possesses excellent heat transfer characteristics and superior insulation properties. The entire heater assembly is encased in either stainless or chrome steel sheath and is compressed under high pressure. The completed assembly is heated under controlled conditions to bake and semi vitrify the refractory for a rigid, vibration resistant, heavy-duty heating unit.

Strip heaters can be finned to improve heat transfer. The fins are specially designed to provide maximum surface contact for good heat dissipation into the finned cross sections, thus resulting in rapid heat transfer to the air.


Applications: Ovens, Hot Plates, Clamp-on water heating, Coffee urns, Vacuum pumps, Vulcanizers, Autoclaves, Core baking ovens, Space Heating, Pre-Heaters, Food Warmers, Dies, Mold heating, Valve houses, Pipe lines, Process welding, Platens, Melting, Baking, Tank Heating, Incubators, Air Heating, Ink drying, Crane cabs, Sealing Bars, Load Bank resistors, and Packaging.
