375 Finned Strip Heaters

Efficiently Conducts Heat from Nickel-Chrome Element Wire to the Sheath

Watlow's 375 finned strip heaters are constructed of highly-compacted MgO-based insulation, which conducts heat efficiently from the nickel chromium element wire to the sheath. Two-inch wide (51 mm) aluminized steel fins are attached in a way that maximizes surface contact so heat is transferred into the air faster. Lower sheath temperature and element life are all maximized by this finned construction.

Finned strip heaters com in available lengths from 5 1⁄2 to 48 in. (140 to 1220 mm).

Features & Benefits


Nickel chromium element wire is centered for heat uniformity

Aluminized steel sheath operates at higher temperatures and reduces corrosion

Optional 430 SS sheath provides a solution for extreme corrosive environments

Welded post terminals produces strong connections
