The Directory lists the names, addresses and
trade names of the participating manufacturers
and their certified products.
STANDARD CAPACITY RATING
DEFINITIONS
Standard Rating. A Standard Rating is a rating
based on tests performed at Standard Rating
Conditions set forth in ARI Standard 810.
Standard Ratings include the following:
1. Ice Harvest Rate
The amount of 32°F [0°C] ice harvested per
twenty-four (24) hours (corrected to 144
Btu/lb [336 kJ/kg]), stated in multiples of 1 lb
[0.45 kg]. Cube-type ice-makers are
considered as producing 100% quality ice.
2. Condenser Water Use Rate
The amount of water used by the
condensing unit (if water-cooled), stated in
gallons per 100 lbs [L/45 kg] of ice, as
determined in 1. above.
3. Potable Water Use Rate
The amount of potable water used in making
air, including blow down, stated in gallons
per 100lbs [L/45 kg] of ice, as determined in
1. above.
4. Energy Consumption Rate
Total energy input rate, stated in kWh per
100 lbs[45kg] of ice, as determined in 1.
above. For split systems, include condenser
fan power.
The conditions of test for Standard Ratings are
as follows:
Ambient temperature....................90°F [32.2 °C]*
Water inlet temperature..................70°F [21.1°C]
Water inlet pressure .30 ± 3 psig [207 ± 21 kPa].
*For a split system unit, the condenser air inlet
temperature shall be 90°F [32.2°C].
APPLICATION RATINGS
Ratings at conditions other than at Standard
Rating Conditions may be published as
application ratings, and shall be based on data
determined by the methods of testing prescribed
in ARI Standard 810.
Wherever application ratings are published or
printed, they shall be accompanied by the
Standard Rating, clearly designated as such,
including a statement of the conditions at which
the ratings apply.
FAILURE TO COMPLY WITH PROVISIONS
OF THE PROGRAM
If it is demonstrated that a manufacturer has
misrepresented the ratings or other
requirements of the ARI Standard and has failed
to make proper correction, the right to use the
Symbol will be withdrawn, not only for the
specific model concerned, but for all models
produced by the manufacturer, and the
manufacturer’s name and listing will be removed
from the Directory.
TOLERANCES
To comply with these standards, published
ratings shall be based on data obtained in
accordance with the provisions of ARI Standard
810, and shall be such that any production unit
selected at random and tested shall produce an
ice harvest rate not less than 95% of the
published rate and an energy consumption rate
not more than 105% of the published rate. The
actual amount of water used shall be not more
than 110% of the published amount.
