Automatic Commercial Ice Makers

Department of Energy

Manufacturers have been required to comply with the Department of Energy's (DOE) energy conservation standards for certain automatic commercial ice makers since 2010. Automatic commercial ice makers make and harvest cube, flake, tube, and nugget ice. Ice makers are used in hotels, hospitals, schools, office buildings, supermarkets, and other facilities where foods and beverages are served or sold.

    Summary: The Department of Energy (DOE) is initiating an effort to determine whether to amend DOE's test procedure for automatic commercial ice makers (“ACIM” or “ice makers”).

    N/A

    Beginning in January 2018, automatic commercial ice-making equipment producing cube ice with harvest rates between 50 and 2,500 lb of ice per day shall meet the amended energy consumption standards shown on Table 2. Standards shown on Table 2 for batch type ice makers represent amendments to existing standards set for cube type ice makers, and new standards for cube type ice makers with expanded harvest capacities up to 4,000 pounds of ice per 24 hour period (lb ice/24 hours) and an explicit coverage of other types of batch machines, such as tube type ice makers.

    The December 2014 Final Rule provides new standards for continuous type ice-making machines, which were not previously currently covered by DOE’s existing standards. Beginning in January 2018, each automatic commercial ice maker producing flake or nugget ice (and other ice produced by way of continuous processes) shall meet the energy consumption standards shown on Table 3.

    Amended Test Procedure

    DOE published amended test procedures for automatic commercial ice makers on January 11, 2012. Manufacturers must use the amended test procedures beginning January 7, 2013.
