Accelerating Innovation

Our first application of our technology, the PX® Pressure Exchanger®, revolutionized seawater desalination by addressing a key pain point: energy intensity. The PX reduces energy use by up to 60% in desalination facilities – significant savings that improve our customers’ operational profitability while reducing carbon emissions. Today, we deliver PX-based solutions for desalination, wastewater treatment, and CO2 refrigeration, and we continue to push the boundaries of what our pressure exchanger can do.
