Industry Leaders

HFC-free refrigeration technology is commercially available for supermarket retailers and stores are already installing these systems worldwide. The industry leaders, some of whom are listed below, recognize the importance of doing their part to reduce their impacts on climate change, and recognize the significant cost savings they can receive in energy efficiency savings by using these HFC-free systems.   These new refrigeration systems being installed use natural refrigerants such as CO2, ammonia, and hydrocarbons.  To learn more about these refrigeration systems click here.

Industry Leaders in the United States

At Supervalu’s Carpinteria, California Albertson’s store, two main HFC free systems were installed, an ammonia primary system and a CO2 medium temperature cascade to a DX system on the low temperature side.  The reduction in total equivalent warming impact of this system, which measures recovery losses, leakage, and energy consumption, is 84% compared to a HFC system.  Supervalu also installed 45 skylights, LED lighting, and glass refrigeration doors, reducing the stores total energy usage by 30%.

Whole Foods
Whole Foods’ first CO2 store was completed in 2009, a low temperature CO2 secondary system. In 2010, the company installed two CO2 cascade systems in California and Massachusetts, and the company plans to open their first CO2 transcritical system at their new Brooklyn, NY location.

Delhaize America has approximately 1,500 stores, with three operating with low-temperature CO2 or as cascade.  Delhiaze will open its first CO2 transcritical store in the U.S., a Hanaford store in Maine, in 2013.

Industry Leaders Worldwide

AEON (Japan)
AEON is the largest Japanese supermarket chain, and one of the largest retailers in Asia.  AEON has been a leader in HFC-free refrigeration, pledging to use natural refrigerants in 10% of all new stores in 2012, 15% of all new stores in 2013, 25% of all new stores in 2014, and 100% of all new stores from 2015 onwards in compliance with the Consumer Goods Forum pledge. They have also pledged to progressively convert 3,500 stores to natural refrigerants.

Drakes (Australia)
In 2007, Drakes became the first chain to install a CO2 transcritical system in the southern hemisphere at its Foodland store in South Australia.

Sobeys (Canada)
This Canada-based chain implemented their first CO2 transcritical system in 2009 and now has installed more than 30 of these systems, which are now their national standard.

Tesco (The United Kingdom)
Tesco was the first chain in the UK to open a store using solely natural refrigerants for its cooling needs. This was achieved with the help of Johnson Controls through the installation of a CO2/HC cascade system. Tesco was also the first to install a CO2 transcritical system in the UK in 2006.
