Scotsman (C0522SW-1A) - 549 Lb Half Size Cube Ice Machine - Prodigy Series

One of the best things about the Prodigy series of ice machines is the water sensor. It's a two-probe sensor that monitors the water's hardness and purges the machine every so often to reduce mineral buildup that hard water can cause. Another kind of build-up that ice machines fall victim to is scale or slime build-up caused by mold and other microbes in the water supply. When the machine is purged, the microbes in the water will go with it, but not the ones already clinging to the walls. A filtration system on the incoming water supply will prevent those pesky critters from setting up shop in the first place. Of course, you will still have to clean and sanitize the machine every so often, because nothing is 100% effective, but regular cleaning is pretty close.
