Freezer and refrigeration technologies continue to change in a wide range of ways, from mechanical and electrical designs to the controls and energy efficiencies to the places such units are used. Units are now in such sectors as convenience stores, food distribution, grocery stores, restaurants, and many other locations. Units range from display merchandisers to walk-in coolers and freezers to 10,000-sq-ft refrigerated warehouses.
Another trend is toward single-duty cases that cater to the expanding needs of delis, convenience stores, and other applicable markets. They are available in both high- and low-profile versions.
