EPA Approves CO2 for Commercial Refrigeration

Hill Phoenix system among groundbreaking technology.

The use of carbon dioxide (CO2) for use in commercial refrigeration was given a significant boost in September, when the U.S. Environmental Protection Agency (EPA) approved the use of carbon dioxide (CO2), as a replacement for hydrochlorofluorocarbon (HCFCs) in retail refrigeration.

The approval came under the EPA’s Significant New Alternatives Policy (SNAP) program, which evaluates alternatives to substances being phased out to protect the stratospheric ozone layer.

Hill PHOENIX, Conyers, GA had conducted lab and field testing for more than a year before submitting its SNAP application, and will continue to test CO2 projects in the fall of 2009. CO2 will be offered as an option in the company’s Second Nature® low temperature and medium temperature products in late 2009.

CO2 can be used to replace R-22, R-507A or R-404A.

According to David Hinde, manager of research and development for Hill PHOENIX, CO2, refrigeration systems will reduce HFC refrigerant leaks and the HFC charge anywhere from 60 to 90%. The sustainability savings that will result from the elimination of refrigeration leaks that occur over time will be equivalent to more than 1,600 tons of carbon emissions over 10 years.

“Many retail food operators are already working hard to reduce their carbon footprint,” notes Scott Martin, director of sustainable technologies for Hill PHOENIX.
