MWR FOURGROUP STARTER/CONTROL PANELS > CONTROL PANEL WITH INVERTER (AVF1) |
 |
General Description The control panels with frequency inverter regulate the rpm of centrifugal or submersible pumps in order to reduce the energy consumption and allow a better regulation more easily adaptable to the variation of flow or pressure demand of the system. An electronic pressure transducer (optional) allows to keep the system at a constant pressure set and to decide a differential pressure in which the speed of the pump can vary. The system will make the pump work with a variation of speed in the range of pressures set as above. |
