About Energy Recovery
Energy Recovery (Nasdaq: ERII) designs and manufactures world-class energy-saving technology for critical infrastructure that communities rely on every day, driving a more resilient and sustainable future. Grounded in more than 30 years of leadership in the desalination industry, today we use our proprietary pressure exchanger technology to help customers in multiple industries improve their operations and lower their emissions. Headquartered in the San Francisco Bay Area, we operate manufacturing and R&D facilities throughout California, with sales and on-site technical support available globally.
Our energy recovery devices save our customers approximately USD $7.2 billion in energy costs annually.
High-Performance Solutions
Our core pressure exchanger technology is at the heart of many of our products. It is designed to efficiently capture and transfer pressure energy, making commercial and industrial processes more efficient and environmentally sustainable, lowering costs, saving energy, and minimizing emissions.
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.
