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