Hitachi Industrial Equipment Systems
Dual controller and energy-saving control to avoid water outages, compact water supply unit.
Features 1. Enhanced Water Supply Avoidance Function [Equipped with Dual Controllers] Two controllers with built-in inverters are installed, creating a dual system for the pump that allows for mutual monitoring. This ensures that if one controller stops for any reason, the other will take over and continue operation. In the event of an abnormality in the pressure sensor, the system switches to motor load current control, maintaining constant discharge pressure control without stopping the pump, thus continuing operation. 2. High Energy-Saving Effect with "Estimated End Pressure Constant Control" and "Low-Speed Standby Operation" to Reduce Power Consumption The pump's rotation speed is adjusted according to the water usage, changing in line with the piping resistance to maintain constant end pressure. Additionally, when a cutoff operation is detected for a certain period, the rotation speed is reduced for operation. These features achieve low power consumption and high energy-saving operation, reducing energy use by 10-15% compared to constant discharge pressure control. For more details, please contact us.
