CO2/Ammonia Cascade System Proves Effective in Retail Settings
Supermarkets can future-proof their refrigeration systems using natural alternatives
Ongoing and evolving U.S. Environmental Protection Agency (EPA) and Department of Energy (DOE) regulations have created a complex landscape for supermarket owners. The pressure to reduce emissions and find safe, sustainable, low-global warming potential (GWP) refrigerants has led to the incorporation of natural refrigerants, such as CO2, in supermarket refrigeration systems around the world.
So, when Keith Milligan, financial controller of JTM Corp., decided to build a new Piggly Wiggly grocery store in Columbus, Georgia, he knew he wanted to install a refrigeration system that was both energy-efficient and environmentally friendly. JTM Corp. operates 19 Piggly Wiggly supermarkets in Georgia and Alabama.
