The PX260 is ERI’s largest commercially available energy recovery device and the new flagship of the PX Pressure Exchanger® family of products. It handles brine flow rates of 50 to 59 m 3 /hr (220 to 260 gpm) – nearly 20% greater capacity than ERI’s former largest device. Arrays of PX260 devices serve reverse osmosis (RO) trains with permeate flows from 850 cubic meters per day (224 thousand US gallons) up to the largest being designed: 25,000 cubic meters per day (6.6 million US gallons) and more. Similar to PX180 and PX220 devices, the PX260 is designed to provide up to 98% efficiency. However, with its higher device capacity, fewer units are needed on a manifold. The PX260 has been successfully beta tested for over two years and is in full production.
The new PX30S Pressure Exchanger device is ERI’s smallest energy recovery unit, designed to handle brine flows from 4.5 to 6.8 m 3 /hr (20 to 30 gpm) for RO plants with permeate capacities of 100 to 360 cubic meters per day (26 to 95 thousand US gallons/day)
Similar to other PX products, at the core of each PX260 and PX30S unit is a tough, engineered ceramic cartridge with only one moving part that automatically adjusts to process flow variations. Efficiency and mixing are the same at all flows. The simple elegant design requires no artificial intelligence or adaptive control schemes to operate. Arrays of devices have built in redundancy, operating in parallel to service larger systems.
With this latest product introduction, ERI continues to offer the simplest, most reliable approach to isobaric energy recovery available today. Currently, ERI’s patented PX technology is making cost efficient desalination of seawater possible in over 30 countries worldwide, covering five continents.

About ERI®
Energy Recovery, Inc. (ERI) is the global leader in high efficiency energy recovery products and technology. Our PX Pressure Exchanger® (PX) energy recovery device is making desalination affordable. The PX device is rotary positive displacement pump that recovers energy from the high pressure waste stream of SWRO desalination systems at up to 98% efficiency with no downtime or scheduled maintenance. Since its introduction in 1997, PX technology has emerged as the industry standard solution for SWRO desalination. There are currently over 6,000 PX units installed or contracted in SWRO plants worldwide, significantly reducing the cost to produce over 5.2 million cubic meters (1.4 billion US gallons) of fresh water per day, and saving customers an estimated 500 MW of energy or over $350 million a year in operating costs.
ERI’s headquarters is situated in the San Francisco Bay Area; San Leandro, California USA with offices in every continent of the globe including: Sunrise, Florida; Madrid, Spain; Abu Dhabi, UAE; Shanghai, China; and service representatives in Sydney, Australia.
