Commercial warewashing equipment OEMs cannot be sure that customers will use the appropriate water treatment systems, so commercial warewashing appliances may be at risk for scale build-up. Over time, poor water conditions may build up scale or deposits on heating elements. This scale effectively insulates the heating elements, causing them to overheat and eventually fail.
The supplier announced it was the first in the industry to manufacture an innovative, scale build-up detection sensor, the patent-pending CaGuard. As scale builds up on the sensor, the controller continuously analyzes the temperature output signal. Using feedback diagnostics, the sensor works in conjunction with the controller to alert the operator when cleaning cycles are necessary, or when an element may be experiencing an over-temperature situation. In addition, the CaGuard scale detection sensor functions as a back-up indicator of a "no liquid" condition, averting premature element failure and avoiding the possibility of dry starts.
