CaGuard was developed for OEMs serving the ware washing, parts washing and steam application markets. OEMs typically cannot ensure that customers will use appropriate water treatment systems, so the equipment they sell is at risk for scale buildup. Over time, poor water conditions can cause scale or deposits to accumulate on heating elements. This scale effectively insulates the heating elements, causing them to overheat and eventually fail. 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 overtemperature situation. In addition, the sensor functions as a backup indicator of “no liquid” condition, averting premature element failure and avoiding the possibility of dry starts.
