Construction Styles
No options available for this section based on your selections
Channel Strip Heater With Mounting Tabs
Heaters are available with mounting tabs. When supported by mounting tabs, the terminal end should be secured firmly. Opposite end should be loose to allow for thermal expansion. Mounting Slot Size Standard 5/16″ × 1/2″ Special Bushings 1/2″ × 5/8″
Channel Strip Heater Without Mounting Tabs
Heaters without mounting tabs have ends that are silver soldered shut to prevent moisture and contaminants from entering the heater. For surface mounting installations, Channel Strip heaters must be securely clamped along their entire length to a smooth metal surface.

Power Variations
No options available for this section based on your selections
Type DW: Distributed Wattage
Channel strip and finned channel strip heaters can be designed to vary the wattage along the length of the heater. Specify number of zones and the required watts and length per zone. Shown with T4 termination.
Type 3PH: Three Phase
In order to minimize the gauge of the wiring on high wattage channel strip and finned channel strip heaters, 3-phase elements can be designed.
Type DV_: Dual Voltage (1 and 2)
Channel strip and finned channel strip heaters can be designed using 3-wire series/parallel circuits for dual vltage applications. Whether the heater is run on the high or low voltage, the wattage will be the same.
DV1: 120/240 volts
DV2: 240/480 volts
Type DWV: Dual Circuits
Independent resistance elements can be designed in a single channel strip or finned channel strip heater for added versatility.
Type GL: Ground Lead/Sheath
For those applications requiring a separate ground lead attached to the channel strip or finned channgel strip heater sheath.
