Energy Recovery to Launch Second PX G1300™ Installation with Vallarta Supermarkets

Energy Recovery and Vallarta Supermarkets today announced plans for a second installation of the PX G1300™ energy recovery device at a store in Salinas, CA. This agreement comes after Vallarta Supermarkets installed their first PX G1300 into an existing CO₂ refrigeration system in their Indio, California store, where the PX G1300 drove 30% energy efficiency over the system’s adiabatic cooler.

“We are thrilled with the results we have seen in our Indio store. We are continually looking for ways to reduce our energy consumption and emissions as part of our sustainability goals,” said Sandie Nunez, Vallarta Store Development Manager.

Vallarta upgraded its Salinas CO₂ system with the PX G1300 to provide a safeguard against increasingly frequent heat waves and reduce energy costs. At the Indio location, the PX G1300 reduced the total energy workload by 30%, driving efficiency from the system’s MT compressor and adiabatic cooler. This impressive energy reduction demonstrates the efficiency the PX G1300 provides and its ability to create resilient systems during heat waves, as the performance improvement was measured above the existing adiabatic cooler between 95°–105°F.  

“The PX G1300 has made our CO₂ refrigeration system more cost-effective and energy efficient, reducing our emissions while mitigating the impact of summer heat waves,” said Steve Goh, Vallarta Supermarkets Director of Energy Management & Sustainability.

The PX G1300 is an application of Energy Recovery’s trusted pressure exchanger (PX) technology, which recycles pressure energy and redistributes it throughout the system to save energy, lower costs, and reduce waste and emissions. Upgrading CO₂ systems with the PX G1300 can increase design temperature by up to 11°F, enabling supermarkets to increase system stability during high heat events*. As many companies transition away from HFC refrigeration systems towards CO₂, Energy Recovery’s PX G1300 technology can help them safeguard against rising temperatures, run more efficiently, and drive down emissions.

“Our continued partnership with Vallarta Supermarkets underscores the value of the PX G1300 to supermarkets, and particularly its strong performance in high temperatures,” said KC Chen, Energy Recovery Vice President of CO₂. “Indio is in the desert of Southern California, where the average summer temperature is above 100°F. With the PX G1300, 111° F will feel like 100° F to a CO₂ system – a meaningful difference that allows supermarkets to stay open during a heat wave without breaking the bank on energy costs and maintenance.”

*Estimated increase in design temperature assumes comparison to a CO₂ system with high pressure value with a 120 KW MT, 30 KW LT system and 100° F / 37.7°C gas cooler exit temperature.  Results may vary from site to site, as design maximum is site-dependent.
