                          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.
