에너지 효율
가치 제안
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.
솔루션 아키텍처
주요 특징
- 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.
