Energy Recovery, Inc.

Energy Recovery, Inc. designs and manufactures energy-saving technology for critical infrastructure. The company was incorporated in Delaware in 2001. Its corporate headquarters, principal research and development, and manufacturing facility are in San Leandro, California, with additional manufacturing and warehouse space in Tracy, California. Energy Recovery uses its proprietary pressure exchanger technology to help customers improve operations and lower emissions across multiple industries. This technology efficiently captures and transfers pressure energy, making commercial and industrial processes more efficient and environmentally sustainable by lowering costs, saving energy, and minimizing emissions. The technology is applicable to industries using pressurized fluids, including liquids and gas, and is suitable for a wide range of pressure ratings. The pressure exchanger acts as a fluid piston, transferring energy between high- and low-pressure liquid or gas through continuously rotating ducts. The design includes micron-level clearances between the rotor and stationary components, where circulating fluid acts as a lubricated bearing to minimize frictional losses and wear. The company has a global direct sales team and on-site technical support staff serving customers in the U.S., Europe, North, South and Latin America, the Middle East, Northern Africa, and Asia. On February 25, 2026, the company decided to wind down operations of the CO2 retail grocery business within its Emerging Technologies segment.
