According to the Food Marketing Institute, there are more than 38,000 grocery stores in the U.S. with an average total store size of 41,300 square feet. Each of these stores, according to EnergyStar, has one refrigerated display case per 1,000 square feet. This adds up to over 1.5 million cooler cases across the country.
And these systems do not come cheap. At over $1,500 per unit, grocery stores pay more than $2.5 billion for these refrigerated display cases, which are designed to last, at best, ten years. However, this is only possible if you keep them clean, according to Mike Perazzo with Kaivac, manufacturers of professional supermarket cleaning systems.
