AHR Expo – Energy Recovery

Energy Recovery (NASDAQ: ERII) will be exhibiting at the AHR Expo, a unique forum that convenes manufacturers of all sizes and specialties to showcase the future of refrigeration technology. The show will take place from Jan. 31 through Feb. 2, 2022, in Las Vegas.

Members of Energy Recovery’s sales and technical team will be at Booth No. C6810 to exhibit the Company’s new PX G1300™ energy recovery device, which has been designed to reduce energy consumption and operating costs in carbon dioxide (CO2) refrigeration systems. This technological breakthrough comes at a time when the Biden Administration has pledged to reduce HFCs, a predominant component in air conditioners and refrigerators, by 85 percent over the next 15 years.

Carbon dioxide is one of the most sustainable and safe natural refrigerants and the transition to CO2 based refrigeration systems is continuing to accelerate. The PX G1300 energy recovery device reduces the energy consumption associated with CO2 refrigeration systems in a broad range of operating conditions helping ensure grocers are compliant with upcoming GWP reduction regulations.

“The PX G1300 addresses both the sustainability and cost challenges of grocers,” said KC Chen, VP of Engineering and New Product Launch. “This technology, which has been trusted by the desalination industry for decades, aims to not only reduce energy consumption and lower operating costs, but also reduce emissions associated with energy consumption.”

This year’s AHR Expo will take place in-person, and masks are required for all attendees indoors, including vaccinated individuals. Participants will benefit from the ambiance and networking of a live event, knowing that protocols are in place to ensure a safe and exciting conference.

Energy Recovery Signs Agreement with Vallarta Supermarkets for First Commercial PX G Deployment

SAN LEANDRO, Calif. and SAN FERNANDO VALLEY, CA— November 2, 2021 — Energy Recovery, Inc. (NASDAQ: ERII) and Vallarta Supermarkets, a California-based company with more than 50 locations, today announced an agreement to install Energy Recovery’s PX G1300 (PX G) energy recovery device in Vallarta Supermarkets’ store located in the City of Indio in Southern California.

“As we’ve committed to doing all we can to reduce our impact on the environment, we have been hunting for new technology and solutions that will enable us to operate our current CO2 refrigeration unit more efficiently and use less energy,” said Miguel Gonzalez, CEO for Vallarta. “We are thrilled to find a solution with Energy Recovery, and the efficiencies made possible by the PX G will ultimately help us meet our sustainability goals.”

Over the last several years, Vallarta Supermarkets has implemented an energy efficiency program that has led to a 15% reduction of electricity consumption across the majority of their stores. In September 2019, Vallarta Supermarkets was awarded the 2019 Clean Energy Champion by Southern California Edison in recognition of the company’s sustainability efforts.

Vallarta Supermarkets will install the PX G in the Indio store’s carbon dioxide (CO2) refrigeration system. The PX G can reduce the energy consumption and operating costs of CO2 refrigeration in a broad range of operating conditions. While CO2 systems are more environmentally friendly than incumbent refrigerants such as climate damaging hydrocarbons (HFCs), CO2 systems are more energy intensive to operate, especially in warmer climates such as Indio where temperatures regularly reach above 100 degrees Fahrenheit/38 degrees Celsius. The PX G is designed to solve this challenge, making it financially attractive for retailers to make the switch to CO2 systems.

“Left unchecked, HFCs are projected to increase global temperatures by a half-degree Celsius by 2100. With the PX G, our goal is to pave the way for the next-generation CO2 refrigeration system that allows retailers to save on energy costs while complying with regulations phasing out HFCs,” said Robert Mao, Chairman of the Board, President and Chief Executive Officer of Energy Recovery. “We are proud to work with a partner who shares our commitment to sustainability. We look forward to demonstrating the PX G’s performance in a real world commercial environment. Our confidence in our technology’s ability to reduce energy consumption is high and we are putting our money where our mouth is. Under this initial deployment, we will only receive payments based off of the amount of energy we save.”

Energy Recovery Joins NASRC, Introducing Energy-Saving Innovations for CO2 Systems

San Leandro, CaliforniaEnergy Recovery, an energy recovery device manufacturer of technologies that solve complex challenges for industrial fluid-flow markets worldwide, has joined the North American Sustainable Refrigeration Council (NASRC) at the silver level.

NASRC is an action-oriented 501c3 nonprofit working in partnership with the supermarket industry to create a climate-friendly future for refrigeration by eliminating the barriers to natural refrigerant adoption in supermarkets. Natural refrigerants – including ammonia, hydrocarbons, and carbon dioxide (CO2) – have zero or near-zero global warming potential (GWP), making them a climate-friendly alternative to hydrofluorocarbon (HFC) refrigerants.

HFCs are super-polluting greenhouse gases growing faster than any other greenhouse gas on the planet, and phasing them out has been identified as one of the most impactful climate solutions globally. As a result, supermarkets are facing increasing regulatory pressures and new corporate sustainability commitments to transition away from HFCs. Though natural refrigerants are the most climate-friendly solution, unique market challenges such as upfront cost premiums, service readiness, technology gaps, and uncertainty around energy performance have prevented their widescale adoption.

Energy performance is particularly important to achieving the lowest possible carbon footprint in supermarkets, as they represent the most energy-intensive type of commercial building, and their refrigeration systems are usually the largest source of energy use. CO2-based refrigeration systems have faced particular scrutiny for energy performance challenges in warm ambient climates. Though CO2 often performs well as a refrigerant in cool ambient climates, it has been shown to be less energy efficient in warm ambient climates without additional energy-saving design features.

Energy Recovery, which focuses on designing and manufacturing solutions that make industrial processes more efficient and sustainable, is working to address that challenge. The company’s newest pressure exchanger device, the PX G1300, allows CO2-based refrigeration systems to operate more efficiently in all ambient temperatures. It works by harvesting pressure energy to reduce compressor work and lessen power requirements, in turn increasing the efficiency of the system and contributing to a lower overall carbon footprint.

“Energy Recovery has been making industrial processes more sustainable and affordable for nearly three decades, and we’re excited that our innovative technology can do the same for the CO2 refrigeration industry,” said Kuo-Chiang (K-C) Chen, vice president of engineering and new product launch, Energy Recovery. “Our PX not only enables the use of natural refrigerants that have a significantly lower global warming potential, but also reduces electricity use of the entire system. We’ve found a partner with a shared goal in the NASRC, and we look forward to working together to future-proof CO2 refrigeration.”

The company has now joined NASRC’s network of over 140 stakeholders from across the refrigeration industry who are all contributing to NASRC’s work to advance natural refrigerants.

“We welcome Energy Recovery to our growing network and look forward to leveraging their expertise,” said Danielle Wright, executive director of NASRC. “Optimizing energy performance is critical to the future success of natural refrigerants and to achieving the maximum emissions reduction potential in the supermarket sector.”

NASRC’s membership network represents more than 38,000 US food retail locations and stakeholders from virtually every sector of the commercial refrigeration industry, including service contractors, manufacturers and suppliers, consultants, engineering firms, trade associations, distributors, and nonprofits.
