Delhaize America has around 1500 stores, with 3 operating with low temperature CO2 or as cascade, and one CO2 transcritical project is planned for 2013. Almost two years ago Fresh &Easy installed its first natural refrigerant system, a subcritical CO2 system. Also installed are self-contained propane cases. Whole Foods’ first CO2 store was completed in 2009, a low temperature CO2 secondary system. In 2010 the company installed two CO2 cascade systems the company is now working on the design of their first CO2 transcritical store. Sobey’s last 28 installations have been transcritical CO2 systems with the latest racks small enough to fit in the mechanical room next to the existing rack, allowing the store to remain open 24/7 throughout the retrofit.  Supervalu has over the years invested in various types of systems ranging from glycol to ammonia. The latest installation is an innovative ammonia installation that has a Mayekawa ammonia primary system on top of a Hill PHOENIX CO2 system for the medium temperature cascaded to a DX system on the low temperature side.
