SAN LEANDRO, Calif.—November 29, 2016 — Energy Recovery, Inc. (NASDAQ:ERII), the leader in pressure energy technology for industrial fluid flows, today announced that the company has been awarded another brownfield retrofit opportunity to install its industry leading PXTM Pressure ExchangerTM technology. The retrofit, located in the Middle East, marks the first time the Company will retrofit a plant using technology produced by Isobarix, which intended but failed to replicate the proprietary Pressure Exchanger solution. It is expected to ship in the 4th quarter of 2016.

The plant selected Energy Recovery to supply its Q-Series PX devices to replace the Isobarix technology, which has caused unacceptable levels of noise and vibration, as well as high maintenance costs. Energy Recovery’s PX devices will allow the plant to lower costs and enhance performance around noise, vibration, and safety.

Offering an industry-best return on investment, and designed to run with the highest efficiency and availability in the desalination industry, Energy Recovery will continue to seek out opportunities to retrofit small, medium and large-scale facilities around the globe.

Energy Recovery’s President and CEO Joel Gay stated, “This plant retrofit is a particularly seminal moment in the Company’s history and furthers our position of technology leadership within the global desalination market. A core tenant of our strategy in this segment is to target plants with inferior technology, demonstrate the superiority of our offerings, upgrade the plant and add to the portfolio of customers who are Pressure Exchanger loyalists. Isobarix’s technology operates under similar fluid physics principles as our flagship Pressure Exchanger but with decreased efficiency, reliability and performance. That we were able to unseat copycat and indeed inferior technology solidifies Energy Recovery’s pole position in the ongoing technology race within not only the global desalination market, but all core markets in which we arbitrage pressure energy and preserve pumping assets. In the past, we have believed that at least one Isobarix product infringes on certain of our intellectual property and this retrofit provides us with a further opportunity to investigate our belief and potentially discover other potential infringements. We will continue to aggressively execute against our long-term strategy with an increasing focus on protecting our intellectual property from those who would seek to otherwise usurp it.”
