Energy Recovery (NASDAQ:ERII) (NASDAQ: ERII) is an energy technology company specializing in the design and manufacture of high-efficiency devices that capture and repurpose energy in fluid-handling applications. The company’s core offering, the Pressure Exchanger® (PX®) device, enables seawater reverse osmosis (SWRO) desalination plants to recover and reuse hydraulic energy that would otherwise be lost during brine discharge. By integrating PX technology into desalination processes, Energy Recovery helps operators significantly reduce the energy consumption and operating costs of producing fresh water from seawater or brackish sources.
In addition to desalination solutions, Energy Recovery has expanded its portfolio to serve the oil and gas sector through turbocharger systems that improve the energy efficiency of hydraulic fracturing operations. These turbochargers capture pressure energy from flowback fluids and convert it into mechanical power to boost pump performance, thereby reducing fuel usage and emissions. The company also provides engineering services, aftermarket support and digital monitoring tools that optimize the performance and reliability of its equipment over long service lifetimes.
Founded in 1992 and headquartered in San Leandro, California, Energy Recovery went public in 2008 and has since supplied thousands of PX devices to desalination and industrial plants around the world. The company has established regional sales and service offices across North America, the Middle East, Europe and the Asia-Pacific region, supporting large-scale municipal and industrial water treatment projects as well as on-site energy recovery solutions for oilfield operations. Its technologies are credited with reducing global carbon emissions by maximizing energy reuse in critical fluid-processing industries.
Energy Recovery’s management team combines expertise in mechanical engineering, fluid dynamics and renewable energy systems. The company’s leadership emphasizes continuous innovation, working closely with customers and research partners to expand the applications of its energy recovery platforms. Through a commitment to sustainability and operational excellence, Energy Recovery remains focused on driving down the cost of water and improving the environmental footprint of fluid-handling processes worldwide.
