The average refrigerant leak rate for food retail, grocery stores is estimated to be 25% per year (following GreenChill’s report). That’s a considerable amount of lost refrigerant, which inevitably needs replacing to ensure refrigeration systems are working at optimal levels. With increasing refrigerant costs, this can have an immense impact on a supermarket organization’s profits, especially with an industry average profit margin of just 1.2%. For example, an organization operating at just 1% margin, saving $10,000 in refrigerant re-charge is the equivalent to generating $1,000,000 of revenue. In fact, if every supermarket in the United States joined GreenChill and reduced refrigerant emission to the current GreenChill average, the industry would save an estimated $108 million per year on Refrigerant Costs [source: https://www.epa.gov/sites/production/files/documents/GChill_Retrofit.pdf]
