Proven technology, now at a larger scale
With no risk of overspin, the MPE 70 operates safely at maximum flow rates and reduces membrane feed salinity increases due to mixing. The resulting system-wide energy efficiency in medium and large SWRO plants is unparalleled by any other ERD.
The low-voltage motor effectively eliminates rotor stops due to biofouling and enables integration of ERD control into the SWRO plant’s automation systems. Electrical data from the ERDs can now be analyzed for predictive maintenance.
Conceived in collaboration with customers and designed specifically for medium and large SWRO plants, the MPE 70 builds on decades of energy-saving experience and technology and is backed by Danfoss’s global sales, logistics, and customer service experts.

As global demand for lithium, magnesium, and food-grade salt surges, brine mining is emerging as a less environmentally disruptive alternative to conventional mining. But brine valorization is only economically viable if energy use and system complexity are kept in check.
Danfoss APP pumps and iSave ERDs form the foundation of ultra-energy-efficient SWRO and OARO systems. They deliver the precise, stable high-pressure performance needed to make brine valorization commercially and environmentally feasible.
Due to high energy efficiency and reliability, Sea Water Reverse Osmosis (SWRO) is one of the most sustainable and cost effective solutions for converting sea water to potable fresh water. Danfoss is committed to supporting the desalination industry with energy efficient SWRO solutions.
