The eController uses the Internet to deliver real-time control of water treatment systems via a standard browser. The controller for cooling towers, boilers and process water systems includes multiple security levels and email alarm notifications to safeguard systems from outside tampering and to notify users should a problem occur. Logged data points can be saved in intervals of 10 min to 24 hr and graphed using the company’s reporting tools. The Modbus option allows information from the controller to connect to a DCS system.
