Finned strip heaters are used for both forced air heating (mounted in a duct) and natural convection air heating (mounted at the bottom of cabinet type ovens).
The finned strip heater’s basic design consists of a helically wound resistance coil placed in a specially designed ceramic insulator. The resistance coil is mechanically connected to screw terminal for positive connection. Stainless steel rectangular tubing is used to house the heater assembly. All remaining voids are filled with high purity magnesium oxide to increase thermal conductivity and dielectric strength.
Tempco Finned Strip Heaters
Tempco finned strip heaters are manufactured in a full line of standard sizes, electrical ratings and terminations, or can be made to your specifications.
Nickel plated steel fins (SS optional) are mounted to the rectangular tubing. The fins have been 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.
Performance Capabilities:
- Stainless steel sheath temperatures to 1200°F (650°C)
- Watt density up to 40 W/in2 (6.2 W/cm2)
- Maximum voltage 480VAC
- Maximum amperage 600A

Watlow Finned Strip Heaters
Watlow’s 375 finned strip is constructed of highly compacted MgO-based insulation, which conducts heat efficiently from the nickel chromium element wire to the sheath. Two-inch wide (51 mm) aluminized steel fins are attached in a way that maximizes surface contact so heat is transferred into the air faster. Lower sheath temperature and element life are all maximized by this finned construction.
Finned strip heaters come in available lengths from 5½” to 48″ (140 to 1220 mm).
Performance Capabilities:
- Aluminized steel sheath temperatures to 1100°F (595°C)
- Watt density up to 33 W/in2 (5.1 W/cm2)
- UL® approved to 240VAC (File No. E52951)
- CSA approved to 600VAC (File No. LR7392)
