  1. Consists of a condensing unit and ice-making section operating as an integrated unit, with means for making and harvesting ice; and
  2. May include means for storing ice, dispensing ice, or storing and dispensing ice.

10 CFR 431.132

Manufacturers have been required to comply with the U.S. Department of Energy (DOE) energy conservation standards for cube type automatic commercial ice makers with harvest capacities between 50 and 2,500 pounds of ice per 24-hour period since 2010.

Recent and Ongoing Activities

DOE has published a Federal Register notice of proposed rulemaking (NOPR) pertaining to energy conservation standards for automatic commercial ice makers. The Energy Policy and Conservation Act requires DOE to periodically determine whether more stringent standards would be technologically feasible and economically justified and would result in significant energy savings. In this NOPR, DOE proposes to amend and establish standards for automatic commercial ice makers and also announces a public meeting to receive comment on these proposed standards and associated analyses and results.

  • DOE will accept comments, data, and information regarding this NOPR until July 10, 2023.
  • Interested persons may submit comments identified by docket number EERE-2017-BT-STD-0022, by email (, Federal eRulemaking portal (
  • DOE will hold a webinar on Wednesday, June,14, 2023, from 1:00 p.m. to 4:00 p.m.

  • Foreign Nationals interested in participating in this webinar, must be screened by DOE Headquarters Security prior to being granted access. Please email to complete the necessary documentation at least two weeks prior to scheduled meeting date.
  • Additional webinar registration information, participant instructions, and information about the capabilities available to webinar participants will be published on DOE’s website:

DOE has published a Federal Register final rule amending the test procedure for automatic commercial ice makers to update incorporated references to the latest version of the industry standards; establish a relative humidity test condition; provide additional detail regarding certain test conditions, settings, setup requirements, and calculations; include a voluntary measurement of potable water use; clarify certification and reporting requirements; and add enforcement provisions. This final rule also provides additional detail to the DOE test procedure to improve the representativeness and repeatability of the current test procedure.

  • The effective date of this rule is December 1, 2022.
  • The final rule changes will be mandatory for equipment testing starting October 27, 2023. 
  • The incorporation by reference of certain publications listed in this rule is approved by the Director of the Federal Register December 1, 2022.
