Managing refrigerant in a food retail store is important from an environmental, regulatory, and financial perspective. An average food retail store leaks an estimated 25 percent of its refrigerant supply per year. For an individual store, the loss of R-404A (common refrigerant) at $7 per pound, can add up to a sizeable annual expense. Multiply that by the number of stores in the chain and the costs can be largely significant, not including the associated labor or service disruption costs.
