U.L. AND C-UL Recognized No. E177353

• Mechanically-bonded continuous fin assures excellent heat transfer and helps prevent fin vibration at high air velocities.
• Several standard formations and mounting bushings available.
• Standard fin is high temperature painted steel with steel sheath.
• Optional stainless steel fin with stainless steel or incoloy sheath for corrosion resistance.
• 120v, 208v, 240v, 480v available.
• Maximum Sheath Temperature
  750°F (400°C) – Steel
  900°F (480°C) – ST.ST./INCOLY
• Made in U.S.A.

1. Steel, stainless steel, copper, or Incoloy sheathed elements.
2. Element wire situated in proximity to outside surface for maximum heat transfer and minimum internal temperature while preserving good dielectric qualities.
3. Pure magnesium oxide compressed to an optimum density for best heat transfer and electrical insulation at elevated temperatures.
4. Weld connection.
5. Cold pin.
6. Insulator.
7. Standard post terminal.
8. Painted steel or stainless steel continuous fin (approx. 5 per inch)
