Named for its 0.375 in. (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.
