Energy Recovery, Inc. is a manufacturer of energy recovery devices that capture and reuse pressure energy in industrial fluid-flow systems. The company's primary product is the PX Pressure Exchanger, a ceramic device that transfers hydraulic energy from high-pressure reject streams to incoming feed streams. This technology is utilized in seawater reverse osmosis (SWRO) desalination to reduce energy consumption and operating costs.
The company operates primarily through its Water segment, which generates the vast majority of its revenue. This segment serves desalination plant builders, operators, and engineering firms worldwide, with a significant geographic footprint in the Middle East, as well as operations in China and South America. Energy Recovery also manufactures pumps, turbochargers, and provides related replacement parts and maintenance services. Beyond traditional desalination, the company applies its pressure exchanger technology to industrial wastewater treatment applications, such as ultra high-pressure reverse osmosis (UHPRO). While the company previously explored emerging technologies like CO2 refrigeration, it recently announced the wind-down of its retail grocery CO2 business to refocus on its core water markets. Energy Recovery operates as a specialized supplier of components for large-scale fluid handling systems.
