Engineering Note: The PX-Q180 handles up to 180 gpm per device with 96.3% warranted efficiency. The Q-series 65mm housing uses a high-flow ceramic rotor for large SWRO trains. Multiple devices can be arrayed in U, Z, or T manifold configurations to match any RO train capacity. No external power, no membranes, no check valves — the isobaric transfer principle delivers the highest energy recovery efficiency available for seawater desalination.
