New PX Q650 delivers the highest capacity and best performance of any energy recovery device on the market, enabling the lowest specific energy consumption, fewer devices, and smaller footprint for large-scale seawater desalination projects
Industry-leading warranty enhancements double performance and durability coverage across Energy Recovery's high-pressure PX® Pressure Exchanger® (PX) models

Energy Recovery (NASDAQ:ERII), a global leader in energy-efficient technology enabling affordable, reliable water and reduced emissions, today announced the launch of the PX Q650 Pressure Exchanger, a next-generation energy recovery device (ERD) designed to meet the scale, efficiency, and reliability requirements of the desalination industry. The Q650 represents the next evolution of Energy Recovery's PX Pressure Exchanger, delivering higher flow capacity and efficiency with lower mixing, all while maintaining the durability and reliability customers know and trust.

Like all PXs, the Q650 is based on Energy Recovery's proven isobaric design, featuring only one moving part made from highly durable alumina ceramic. This simple design has a 30-year design life, requires no scheduled maintenance, delivers an exceptionally low lifecycle cost, and can reduce a plant's reverse osmosis energy use by up to 60%. Published performance data show that PX Pressure Exchangers deliver the highest uptime of any ERD in large-scale desalination plants.

PX Q650 Benefits

Highest Capacity on the Market: Flow range from 250 to 650 gallons per minute (gpm), representing a 63% increase in peak flow capacity versus the PX Q400 and enabling fewer devices per train and a smaller ERD array footprint.
Ultra-High Efficiency and Ultra-Low Mixing: Peak efficiency of up to 99% and volumetric mixing as low as 2%, resulting in the lowest specific energy consumption on the market.
Wide Operating Flexibility: The highest turndown ratio available.

"The PX Q650 sets a new performance standard for large-scale desalination," said Rodney Clemente, Senior Vice President of Water at Energy Recovery. "It builds on decades of proven pressure exchanger performance while delivering the capacity, efficiency, and reliability today's large projects demand. With the Q650, customers have a highly scalable energy recovery solution that reduces operating costs and long-term project risk."

Warranty Program Enhancement

Alongside the launch of the PX Q650, Energy Recovery is enhancing its product assurance program by doubling ceramic component and performance warranties for high-pressure desalination pressure exchangers sold and shipped on or after March 9, 2026. Enabled by the PX's simple design and long operating life, these enhancements provide additional assurance for desalination plants using high pressure PXs.

Under the expanded program:

Ceramic components are now backed by a 10-year industry-leading warranty
PX device performance is now backed by a 4-year industry-leading warranty (from shipment)

PX Q650 product specifications are available in Power Model Pro, Energy Recovery's configuration tool to help designers plan and select products for their reverse osmosis systems.
