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.
