  • Controlling evaporative cooling tower chemistry
    Patent number: 10151536
    Abstract: The automatic reset of an evaporative cooling water dissolved solids set point based on detection of water softener performance is provided. A controller has a sensor, or is given an input signal, which confirms that the softener is operating properly. Positive confirmation of water softener performance allows the controller to maintain a user specified high total dissolved solids set point in the evaporative cooling water. Should a failure of the softener be detected, the controller then maintains a user specified lower total dissolved solids set point.
    Type: Grant
