Roundy's, grocer in the Midwest of the US opened its first CO2 transcritical store, the Pick 'n Save supermarket in Menomonee Falls, on 14 January 2014. The store is one of the nation’s greenest supermarkets. Its Hillphoenix Advansor CO2 booster system is expected to yield a total carbon footprint reduction of around 11,793 tonnes over 10 years.
Our system is the first of its kind in Wisconsin to use carbon dioxide as its refrigerant," said James Hyland, Vice President of Investor Relations and Corporate Communications for Roundy's. The adoption of the CO2 transcritical refrigeration system is an example of Roundy's commitment to shift towards using natural refrigerants.
We will be conducting an energy analysis through all four seasons,” Hyland added. “We know what to expect from the system, and it appears the cost of the system balances out with comparable systems due to lower installation and operating costs.”
