The groundbreaking D anfoss iSave is a patented, high- efficiency Energy Recovery Device (ERD) that guarantees constant membrane feed in SWRO (sea water reverse osmosis) applications of any size—on land, at sea or on the move. In fact, with iSave, customers of Danfoss are able to have pressure exchanger, booster pump and motor integrated into one compact unit for high efficiency and short pay-back time. “This makes it unique as we can regulate the flow easily and do not need a high-pressure flow meter to balance the system. It’s also very compact because everything is integrated into one,” said Jesper Bentzen, global sales director, High Pressure Pumps, Danfoss. “There are also fewer piping works as well,” said Vijay, sales manager, ASEAN Region, High Press Pumps, Danfoss. The small footprint of iSave makes it a popular solution where space is limited, explained Bentzen. When fitted with iSave, the Danfoss APP pumps produce more fresh water per square metre than any other system in the market.
