Energy Efficiency

                    Optimise water pumping




                    Value proposition

                    Main drivers

                    • To  reduce operating costs
                    • To  sustain energy gains through reliable and efficient equipment operation
                    • The return on the investment should not exceed 24 to 36 months.


                    Value proposition

                    • Up to 30% energy saving 
                    • Controlled by a variable speed drive Altivar 61, motor power at 80% of nominal flux represents only 50% of nominal power in contrast with 95% for traditional control.
                    • You can evaluate your cost saving with the software ECO8.


                    Differentiation factors

                    The pump control will be done by a variable speed drive Altivar 61 equipped with its water "pump switching" card.

                    Main Energy Efficiency characteristics

                    • With its multi-pump option, the Altivar 61 provides flexibility for the management of several pumps.
                    • The variable speed pump is speed-controlled from the pump switching card and up to 4 additional external pumps can be controlled by DOL starters or preferably under soft starter control.
                    • As an option on demand the Altivar can be combined to a RTU (Remote Terminal Unit) that will guarantee acquisition and transmission of events and alarms.
