375 High-Temperature Strip Heaters

Rugged Heater Capable of High Temperatures and High Watt Densities

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

Watlow begins construction by accurately placing a coiled, nickel-chromium element wire in the center of the heater. The element wire is then embedded in magnesium oxide (MgO)-based insulation compacted into a solid mass creating excellent heat conductivity and high dielectric strength. The heater is then enclosed in aluminized steel or 430 stainless steel sheathing.

Features & Benefits


Nickel-chromium element wire is centered in the heater assures uniform heat

Aluminized steel sheath operates at higher temperatures and resists corrosion

Optional 430 stainless steel sheath meets temperature requirements that reach up to 1200°F (650°C)

Over 100 in-stock models in popular sizes and ratings for next-day shipment
