Scotsman ice machines are designed to pump water from a collected sump and slowly pour it over the ice-making tray, which then gradually freezes the water in layers. These machines have AutoAlert indicator lights which signals when it is time to descale and sanitize the machine, as well as keep the user informed about the machine’s operating status. The brand's patented WaterSense adaptive purge control technology delivers maximum reliability by decreasing scale buildup, increasing the time between cleaning / maintenance services. Choose from a wide range of these machines, available in sliding and solid door types on Raptor Supplies.
