A GENERAL REVIEW OF THE RULES FOR SIZING ICEMAKERS AND BINS
1. Ice needs are seldom uniform; more ice is generally needed in summer than in winter. Understanding the ice usage of the
customer is a must to assure sufficient ice is available to meet peak demands. Remember, water temperature, as well as the
surrounding air temperature, affects the output capacity of icemakers. Determine what these factors will be during the
peak demand periods. Then verify the icemaker and storage bin selection by the preceding method and refer to the
machine’s production chart to determine the expected capacity under these conditions.
2. Determine the size of the icemaker required by dividing the “worst case” week’s total ice usage by seven. Then add in a 20%
“safety factor.”
3. If equal amounts of ice are used each day (including weekends), size the bin to match the ice production.
4. If there are peaks (where a day’s usage exceeds a day’s production), size the bin to store adequate ice to meet the peak
demand(s).
5. Remember that the per pound cost of making ice is about four times the per pound cost of storing ice.
It’s always much less expensive for the customer to meet their “peak” demands by using the storage bin when possible.
6. When sizing the bin, double-check the bin’s true capacity, using the current ARI directory.
7. A final element to take into account is the shape of the bin, the location of the icemaker(s) on the bin, and the size and
location of the icemaker(s’) ice discharge. An ice discharge opening centered on an extremely wide bin will result in much
more pyramiding and, therefore, less storage.
