Finned Strip Heater Application Basics

Similar in construction to the Strip Heaters these heaters include fins that make them suitable for air heating applications. Depending on the watt density (noted in catalog tables) these heaters can be used in still air or forced air applications.

As a general rule of thumb, Finned Strip Heaters with watt densities exceeding 20 watts/sq in. must be operated in a forced air system. Watt densities below 20 watts/sq. in. may be operated in still air in most application.

Surface temperature on the heater in combination with watt density, air flows, and system design must not exceed 1200 deg F.

Care should be taken not to over torque the screw and nut terminal posts as breakage of the internal heater connections may occur. Also, connections to the heater should be made with high temperature wire.

As with any electrically heated product, the proper application of Vulcan Heaters and the temperature control is the most important factor in optimum performance, efficiency, and longevity. No two systems are alike. It is extremely important that attention has been given to the total product or system design as well as operating environment.

Please refer to general application guidelines, recommended watt densities, sheath temperature limitations, corrosion guide, and other engineering data to assist you with product selection.
