- Mount across Air Stream within Forced Air Ducts
- Use in Dryers, Ovens and other Process Air Heating Equipment
- Comfort Heating in Ducts, Load Banks and Humidity Controls
- Many Air Blast and Convection requirements can be accommodated by the wide range of lengths, wattages and watt densities available.
Selection Guidelines
Maximum Work Temperatures — Finstrip® elements can generally be used in the applications above, at maximum temperatures, without exceeding their capability, if properly installed according to instructions packed with heater.

Note - Maximum temperatures are based on 15 W/In2 density for iron sheath and 20 W/In2 density for chrome steel sheath. If elements have a lower watt density, work temperature may be increased; if watt density is higher, work temperature should be lower.

Options
Secondary Insulation Bushings are needed at each end of Finstrip® elements when connected in series on line voltages 300V and above. To accommodate bushings, a 17/32 x 11/16" mounting hole in tabs should be specified for elements. A secondary bushing set (PCN 255716) should be specified. Each set includes two bushings and hardware for one heater.
