Commercial ice machine

Commercial ice machine.

Commercial ice machines can use many types of cooling and production processes.

Florida Water Star commercial ice machine requirements are based on ENERGY STAR® standards. These performance specifications are, on average, 10% more water-efficient than standard commercial ice machines.

A cooling system is an essential icemaker component that is generally either air-cooled or water-cooled. Water-cooled ice machines are not eligible for ENERGY STAR® labeling. In addition, flake and nugget ice machines are not eligible for ENERGY STAR® until a sound testing protocol and performance database are established. Any ice machines that do not fit within these categories will be evaluated on a case-by-case basis.

Commercial ice machines are ENERGY STAR®-labeled or meet performance specifications listed below if an ENERGY STAR®-labeled machine is unavailable.
