Danfoss Next Generation iSave 21 Plus

With an increase in demand, Danfoss launches new generation of the popular iSave 21 ERD for smaller SWRO plants. The new iSave 21 Plus ERD with integrated pressure exchanger, booster pump and motor in one compact unit ensures optimum efficiency and short payback time of plants ranging in size from 110 to 350 m3.

iSave 21 Plus captures hydraulic energy from the high pressure reject stream of the SWRO process and transfers the energy back into the system, reducing the energy consumption by up to 60 percent regardless of flow rate and size of the system.
