1-1/2" Wide Stainless Steel Channel Strip Heaters With Mounting Tabs and (2) #10-32 or #10-24 Screw Terminals Offset (Diagonal) At One End

General Product Description

Channel Strip heaters are most commonly used in the surface heating of tanks and in industrial ovens as the heat source via flat-surface mounting and have hundreds of commercial and industrial applications. 

Channel strip heaters differ from regular strip heaters in that their housing is constructed from a singular piece of rectangular tubing which makes them moisture-resistant.

  • Whenever the voltage to ground exceeds 300V, secondary insulators must be used.
  • All strip heaters may be used at voltages lower than rated for reduced wattage.
  • NOTE: For Units With Mounting Tabs: When supported by mounting tabs, the terminal end should be secured firmly. The opposite end should be loose to allow for thermal expansion.
