MPE 70: The first active ERD for medium and large SWRO plants

Integrating a low-voltage motor with an isobaric energy recovery device, the MPE 70 is the world’s first active ERD designed for medium and large SWRO plants.
 
By completely eliminating the risk of rotor overspin, the motor-controlled MPE 70 safely operates at variable and maximum flow rates and reduces membrane feed salinity increases due to mixing.
 
In addition to unprecedented energy efficiency and reliability, the MPE 70 reduces the need for ERD redundancy in larger plants, prevents rotor stops due to biofouling, and facilitates smarter automation and better predictive maintenance.
 
The MPE 70 builds on Danfoss’s proven technology and decades of energy-saving experience.
