Together for a smart and trustworthy power supply
For many years Atlas Copco Rental has been supporting Nyrstar Budel, the only zinc producer in the Netherlands, with temporary power supplies.
The solution: two QAS500 generator sets
This time Atlas Copco Rental came up with an even better solution: two QAS500 in a parallel arrangement. This way the water pump could easily be started, even though the high starting current. Once in operation and the starting current decreases to a nominal capital, one generator could be shut down.
The temporary power supply was constructed just 1 day before the execution, limiting labor costs for Nyrstar.
Jack van Hulten, District Manager of Atlas Copco Rental, looks back on the job: ‘We instructed Nyrstar’s technical department during the construction so they could handle the generators themselves. This made it simple for them to synchronize the 2nd generator and start it safely. This synchronization was executed in a 100% automated manner by the QC4002 control unit, standard on QAS500. Also the load sharing is controlled by this unit, resulting in a 50/50 distribution of the load between the generators.’
Han Hermans of Nyrstar sees a big advantage in the parallel operation of the two QAS500 sets: “If anything occurs with one of the units, the other set automatically takes over without any power interruption. This offered certainty during the operations, especially since we had to completely disconnect the main power supply!.”
Moreover the possibility to shut down and restart the units easily and fast ensured significant fuel savings. An extra saving was on transport and handling: QAS500 units are lighter than QAC1000 container set.
For Han Hermans the proposed solution was a perfect match to Nyrstar’s demand : “Atlas Copco Rental has been a constructive partner and delivered exactly what we needed for this project, both technically and budgetary. This definitely offers a perspective for future projects.”
