Ao Smith 100110124 Flanged Incoloy Element 18KW 480V

Product Description

The AO SMITH 100110124 is a flanged Incoloy heating element designed for commercial electric water heaters. It operates at 480/277 volts with an 18 KW output and features Incoloy nickel-alloy sheathing rated for medium watt density applications. The element mounts via a round or square flange with a 2.5-inch bolt circle and includes a gasket for installation. Forged steel flanges provide structural strength under repeated thermal cycling. This element is a direct replacement part installed by licensed commercial plumbers or HVAC service technicians working on large-capacity water heating equipment.

This element is intended for commercial water heater applications where high-voltage, high-wattage output is required. It is compatible with AO SMITH DSE, CMC, SU, and DVE/DHE series commercial water heaters. The Incoloy sheathing resists scale buildup and corrosion in demanding water conditions, making it well suited for commercial facilities with continuous hot water demand. The included gasket simplifies the replacement process and helps ensure a leak-free flange seal on initial installation.
