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.
