1Our Channel Strip Heaters are dependable and reliable flat heating elements – designed to provide efficient heat to flat surfaces from common to industrial applications. Our maximumChannel cross section available channel length is 20 feet. The seamless sheath design of Channel Strips makes them ‘dimensionally’ stable in milled slots. Channel Strips are constructed with a stainless steel rectangular tube with a 1.5” x .312” rectangular dimension and a wall thickness at .030″. The inner construction consists of wound nichrome resistance coil. The inner flexible wire is strung through ceramic insulator pieces. The coils are attached to the screw terminals, or high temperature lead wires, for a positive connection. MgO (magnesium oxide) is used to fill and pack open areas surrounding the coils. The MgO material helps increase the elements thermal conductivity and dielectric strength.

Please call us EST 8-5 pm for any additional custom variation requirements: 513-228-0481.
Customized Options: For liquid immersion applications, we recommend a welded option with tube based leads. The welded end design is the best to prevent MgO leakage, and to ensure all internal components remain uncompromised by a changing external environment. If you require an alternate lead configuration not displayed, please contact us to design a custom solution that meets your needs.
Standard Options: We can build our Channel Strips with standard mounting tabs, or design custom mounting tabs as required for our customers. When mounting tabs are not requested, ends are welded shut to prevent moisture and contaminant damage. Our Channel Strips are available with the following standard options:
  • Threaded Terminals
  • Leads mounted at ends
  • Leads mounted on surface
  • Lead Styles: Plain / Braided / Armor / T-Box
  • With mounting tabs
  • Without mounting tabs
  • With or Heat and Sensor Technology’s unique bulkhead design of bulkhead fittings.
  • Without bulkhead fittings
Mounting Installations: Channel Strip heaters must be clamped securely along a smooth metal surface (along their complete length). When a Channel Strip is supported by mounting tabs, ensure that the terminal is secured firmly, and that the opposite end remains loose to allow for expansion. Do not over-tighten nuts when installing, as over-torquing terminals will create internal heater damage.Channel Strip Max Watt Chart Made in OH USA
