State Sandblaster CSB 50 Gallon Commercial Electric Water Heater, 18 kW

A 50-gallon State Sandblaster commercial electric storage water heater that packs 18 kW into a narrow tank. It serves busy restrooms, kitchens and locker rooms, recovering roughly 82 GPH at a 90 F rise so peak-period draws keep moving.

Three internally fused Incoloy immersion elements with low to medium watt density resist oxidation and scale. Power is 208V, 3-phase, landing on a top terminal block that can be field-configured for single- or 3-phase service. The thermostats have an adjustable set point and a manual high-limit cut-off, and a hinged control compartment door with color-coded circuitry keeps service simple.

A glass-lined steel tank with two anode rods resists corrosion and is rated for 150 psi working pressure, with an ASME 160 psi version available. Plumbing uses 1-1/4 in. NPT connections, bottom inlet and top outlet, plus a brass drain valve, and a T&P relief valve rated to CSA/ASME comes with it. At about 55-3/4 in. tall and 21-3/4 in. across, it passes through doorways easily. It is UL/CSA listed.
