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.
