Concertor reduces energy use in sev- eral ways. For example, Xylem’s patented self-optimising Energy Minimiser auto- matically ensures that all working pumps at any station are running at their most efficient duty points. The pump’s motor complies with IE4 efficiency standards, while Xylem Flygt’s adaptive N-hydraulics in high chrome Hard-Iron™ guarantee sus- tained efficiency on the hydraulics side. Instal lation investment is reduced because the cabinets required for the sys- tem are up to 50% smaller, compared to direct online pump controllers. Concertor achieves this by including variable fre- quency drives (VFDs), integrated intel- ligence, control electronics and climate control equipment into the pump to give a single, pre-engineered and configured pumping system. This frees up space in both existing and new cabinets, allowing for full monitoring functionality without the larger cabinets that would tradition- ally be required. Being fully integrated means that no additional climate control equipment is required; the system is factory configured and tested and, on installation, requires only a connection to small cabinet to give access to the simple installation wizard

In terms of connectivity, Concertor enables a number of pumps to be interconnected via a gateway or controller, or via a modem to a SCADA system. A Xylem HMI monitor can also be added, if preferred.

and the built in supervision and monitoring functions. “Concertor is a breakthrough innova - tion based on Flygt Dirigo TM technology. The new system is enabled by integrating a processor, software, sensors, power electronics, a synchronous electric motor
