The equipment operates unattended, automatically alarms faults and uploads them. Any operational status and control can be displayed and completed in the control room through the system. This system is equipped with a reserved port for connection with the heat network automatic control system, allowing information such as the system's operating status, inlet and outlet water quality, and water tank liquid level to be uploaded to the heat network central control room. Realize 24-hour online automatic monitoring of the hardness of the effluent from the water softening equipment. Test the hardness of the effluent every 15 minutes (the test time can be adjusted), identify the failure points of the resin, and immediately start the resin regeneration program, neither ahead of nor behind schedule. This ensures that the working exchange capacity of the resin is maximized while maintaining the hardness index at the outlet of the water softening equipment within the calibrated range. Compared with the same model of water softener, it can save 20% to 30% of operating costs annually, thereby achieving the purpose of preventing boiler scaling, maintaining boiler efficiency, and energy conservation and emission reduction.
