Product Specification for
Automatic Commercial Ice Makers
Eligibility Criteria
Version 2.0
Following is the Version 2.0 product specification for ENERGY STAR qualified Automatic Commercial Ice
Makers. A product shall meet all of the identified criteria if it is to earn the ENERGY STAR.
1) Definitions: Provided below are definitions of the relevant terms in this document.
A.	Automatic Commercial Ice Maker: A factory-made assembly (not necessarily shipped in one
package) consisting of a condensing unit and ice-making section operating as an integrated unit,
with means for making and harvesting ice. It is an assembly that makes up to 4,000 lbs of ice per
day, and may also include means for storing or dispensing ice, or both.
B.	Air-Cooled: An ice maker wherein motor driven fans or centrifugal blowers move air through the
condenser to remove heat from the refrigerant.
C.	Water-Cooled: An ice maker that utilizes water running through the condenser to remove heat
from the refrigerant.
D.	Batch-Type Ice Maker: An ice maker having alternate freezing and harvesting periods. This
includes automatic commercial ice makers that produce cube type ice and other batch
technologies. Referred to as cube type ice maker in AHRI Standard 810.
E.	Cube Type Ice: means ice that is fairly uniform, hard, solid, usually clear, and generally weighs
less than two ounces (60 grams) per piece, as distinguished from flake, crushed, or fragmented
ice. Note that this conflicts and takes precedence over the definition established in AHRI 810
(incorporated by reference, see § 431.133), which indicates that "cube" does not reference a
specific size or shape.
F.	Continuous-Type Ice Maker: An ice maker that continually freezes and harvests ice at the same
time. The following ice types are produced by continuous machines:
a)	Flake: typically used for cooling food, commercial and industrial process cooling, and special
medical and scientific cooling applications.
b)	Nugget: typically used for cooling water and beverage drinks, and for a chewable ice with a
softer consistency than cube ice.
Ice Machine Categories
G.	Ice Making Head (IMH): A model with the ice-making mechanism and the condensing unit in a
single package, but with a separate ice storage bin.
H.	Remote Condensing Unit (RCU) or Split System Unit: A model in which the ice-making
