iSave – isobaric energy recovery device
Danfoss has introduced the first isobaric ERD that is fully integrated with its own positive displacement booster pump and electric motor. The result is fail-safe flow control - without the use of separate high-pressure flow meters.
The iSave is the direct path to saving 60 % of energy costs
The patented iSave™ isobaric Energy Recovery Device captures wasted pressure from the membrane reject flow and transfers it directly to the membrane feed flow.
With its built-in highpressure positive displacement booster pump and electric motor, the iSave automatically controls high-pressure flow – without the use of separate flow meters – to ensure constant and reliable highpressure feed to the RO membrane.
It’s simple, reliable and fully automatic. Due to near-perfect energy transfer, which in many cases reaches up to 95 % efficiency, net energy consumption can be reduced by up to 60 % compared to systems not using energy recovery.
Energy costs are not all that the iSave reduces. The iSave also enables designers to specify smaller, less costly high-pressure pumps in SWRO systems. And it helps them save space. The iSave has the smallest footprint of any isobaric energy recovery device on the market.
