Perform inverter operation to drive the pump with high efficiency and save electricity.
To adjust the flow, the valve that was partially closed was opened, and by regulating the flow with an inverter, significant power savings were achieved. The inverter operates at the optimal and minimum frequency based on signals from pressure sensors and flow sensors, driving the pump with high efficiency for energy conservation. To prevent the loss of flow that cannot be reduced by the inverter during low demand periods, bypass valve control is also used. 【Features】 ○ Control Method: The rotation speed of the pump motor is controlled by the inverter using pressure sensors and flow sensors. ○ Target Equipment: Absorption chiller/heater Secondary chilled/heated water pumps (11.0 kW) × 2 units For more details, please contact us or download the catalog.
