These compact commercial electric units offer potent performance in a small package, making them well-suited for under-counter installations and adaptable for various wiring setups.

They feature an automatic thermostat control with a fast-acting surface-mount thermostat, incorporating a high limit energy cut-off (with manual reset) for enhanced safety. Heat is efficiently transferred to the water via a direct heat transfer system with an immersed element designed in a screw-in style. Furthermore, they come equipped with a factory-installed Hydrojet sediment reduction system and boast a Vitraglas lining, which is fused to the steel surface at temperatures exceeding 1600 degrees Fahrenheit.

To improve energy efficiency and jacket rigidity, these units feature 1-inch non-CFC foam insulation on the sides and top of the tank, reducing heat loss. They also have factory-installed true dielectric fittings with a 3/4-inch NPT water connection to extend the water heater's lifespan and simplify installation. Additionally, heat traps are built into the design, featuring a flexible disk that minimizes heat loss in piping while eliminating noise potential.

For added corrosion protection and long-lasting service, a protective magnesium rod is included. The steel tank is constructed from heavy-gauge steel, automatically formed, rolled, and welded to ensure a continuous seam for the glass lining.

These units are field-convertible, initially shipped from the factory as standard 3-phase, non-simultaneous units but can be converted to 1-phase and/or simultaneous operation in the field. Lowboy models are particularly well-suited for installations where space is limited, such as in closets or under counters. They also come with a copper screw-type immersion element and the Hydrojet total performance system for non-simultaneous operation.
