The Romanian seed company Jurex srl has installed VLT AQUA Drive frequency converters from Danfoss in its new irrigation pumping station, consisting of two boosters.
The first booster comprises of six 110 kW pumps and the second booster comprises of four 160 kW pumps. A VLT AQUA Drive frequency converter controls each pump.
In both cases, one of the frequency converters acts as master and the others as followers. The master controls the speed of the followers using the VLT Advanced Cascade Controller MCO 102 option and Modbus TCP serial communication.
With VLT AQUA Drive frequency converters controlling the irrigation pumps, it is possible to adapt the pressure and flow in the system to the current demand; resulting in significant energy savings.
Furthermore, the reduction of pressure and the smooth changes in pressure; made possible by the VLT AQUA Drive dedicated software for irrigation applications, provides additional advantages. These functions help to protect the pipe system, resulting in fewer leaks and reduced water loss.
