The Hatco 3CS-9 electric sink heater is a space-saving, high-performance solution for commercial kitchens requiring efficient manual warewashing. Designed to fit under the center of a 21- to 25-inch square sink, this undersink unit provides a continuous supply of 180°F sanitizing water—critical for meeting health department standards while minimizing space consumption.
