PX Q400

Building upon Energy Recovery’s track record of best-in-class performance, the PX Q400 is the next evolution of our industry-leading PX® Pressure Exchanger® technology. Delivering energy and cost savings, the PX Q400 offers the lowest projected life cycle cost of any energy recovery device (ERD) for seawater reverse osmosis (SWRO) desalination, thanks to high performance and lower maintenance. The PX Q400 further innovates and improves upon what came before—enhancing efficiency, capacity, reliability, and value to ensure it remains the most trusted ERD in desalination.

Highly efficient

Highest efficiency at the highest flow compared to our other PX Pressure Exchanger products

Lower mixing

<3% volumetric mixing resulting in higher system performance

Higher capacity

At 400 gpm, it’s our highest capacity PX yet, resulting in 25% fewer devices compared to the Q300*

Lowest life cycle cost

Offers the lowest projected life cycle cost of any ERD for seawater reverse osmosis (SWRO) desalination due to lower maintenance and operational expenditures
