Channel Strip Heaters

Watlow 375 High-Temperature Strip Heaters

Named for its 0.375″ (9.5 mm) thickness, the Watlow® 375 strip heater is a rugged heater capable of both high temperatures and high watt densities.

The 375 strip heater’s ruggedness comes from the design and use of choice materials. Watlow begins construction of the strip heater by accurately placing a coiled, nickel-chromium element wire in the center of the heater. The element wire is then embedded in MgO-based insulation compacted into a solid mass, resulting in excellent heat conductivity and high dielectric strength. Finally, the strip heater is enclosed in aluminized steel sheathing.

Tempco Ceramic Insulated Channel Strip Heaters

Type 304 stainless steel sheath provides physical strength and resistance to high temperatures and corrosion. Dependable at sheath temperatures of up to 1200°F (650°C).

Stainless steel 10-32 threaded screws are standard and are securely fastened (twist-proof). Various termination configurations and options are available.

Specially selected and designed ceramic insulator houses the resistance wire coil, insulating it from the outer sheath.

Helically wound nickel-chrome resistance wire is precisely strung through the ceramic insulator, and is then mechanically connected to screw terminals or lead wires for a strong positive joint.

A custom mixture of several high purity magnesium oxide grain sizes, chosen to increase thermal conductivity and dielectric strength, are used to fill all remaining space inside and around the ceramic insulator.

Channel strip heaters are available with or without mounting tabs. If without, the ends are welded shut to prevent moisture and contaminants from entering the heater. Tabs are not available on 1/4″-thick by 5/8″-wide heaters.

Available with fins for air heating applications.
