When global beverage manufacturer Coca-Cola announced an initiative to optimize its vending machines in order to achieve a 40-percent reduction in energy, it raised the bar for vending equipment suppliers.
In general, vending machine compressors have considerable excess capacity during most of their run time. A high-capacity compressor is required only during pull-down, which is 12 percent of the cycle. This is the time it takes to fully chill the products after they are loaded into the machine in order to bring the beverages to sales temperature as quickly as possible.
