Illustrative main image: the pictured machine and ice load do not identify a stocked model or demonstrate production or usable bin capacity.
The bar runs out of ice at 7:30. The machine’s daily production figure looked generous, and an hour later there is ice in the bin again. The problem was not necessarily the day’s total. It was what was available when the orders arrived.
Choose three specifications separately: the ice form, production under the relevant conditions, and accessible storage through the peak. Then check the complete system against the site and operating task. A larger kilograms-per-day number is not a complete answer to an empty bin at the wrong moment.
This guide works through a fictional hour in 15-minute intervals, including a trap that interval totals can hide. No example figure is a tested machine output or a promise of storage performance.
Choose the ice for the task before choosing the cabinet
Write what the ice needs to do: serve a drink recipe, pass through a dispenser, support a particular presentation or perform a separate food-process task. Get a sample from the proposed model and test that task. Similar-looking product labels do not establish identical size, texture or handling.
| Form | A task to assess | What to test with the actual sample |
|---|---|---|
| Cube or crescent | The intended glass, drink recipe or dispensing arrangement | Piece dimensions, portion mass, handling and presentation |
| Nugget/cubelet | A service specifically calling for that texture and form | Serving method, recipe, equipment compatibility and customer presentation |
| Flake | A task requiring small irregular pieces or a shaped ice bed | Actual contact, drainage, replenishment and food-process requirements |

Hoshizaki Australia distinguishes cuber, crescent, flaker and nugget families in its range. Use those distinctions to shortlist; they do not prove a universal melting time or a saving on drink ingredients. Ice-bed display is a separate application brief, not proof that a food remains safely held.
Weigh the ice used in your actual serving method. “One scoop” is only a useful measurement after the scoop and filled portion are defined. Keep drink ice, preparation use and other departments’ withdrawals separate so the same demand is not counted twice.
A 24-hour rating needs its conditions attached
Ask for the exact model’s production table with ambient-air and incoming-water conditions. Hoshizaki’s Australian IM-45CPE-25-F page, for example, publishes different production figures at different air/water temperature pairs. That is evidence that the conditions belong beside the output, not a derating formula for every machine.
Obtain a supported assessment for your expected installation and water conditions. If the relevant combination is not documented, leave the answer open. Do not invent a standard summer percentage to subtract, and do not assume an ambient operating limit guarantees the same output at every point within it.
Nor should a daily figure be divided by 24 and treated as ice arriving steadily every hour. Ice may be produced in cycles, and controls, operating conditions, cleaning and bin behaviour affect availability. For a peak plan, establish what can actually replenish usable stock during the interval and when it arrives.
A daily demand record still matters: the system must recover between peaks and support the planned opening pattern. But daily totals and peak availability are different tests. Passing one cannot stand in for the other.
A worked peak: enough by the end, short at the counter
Hypothetical arithmetic only. Assume a bar begins a one-hour peak with 18 kg of accessible ice. Requested withdrawals are 8, 10, 7 and 5 kg in successive 15-minute windows: 30 kg altogether. Assume, purely for this example, that 3 kg becomes available at the end of each window, at minutes 15, 30, 45 and 60.
That is 12 kg of assumed replenishment over the hour. It is not taken from a machine’s daily rating, and it describes no named model. The simplified balance ignores melting and other losses; those remain additional inputs in a real plan.
| Window | Opening balance | Requested draw | Replenishment at end | Closing paper balance |
|---|---|---|---|---|
| 0–15 min | 18 kg | 8 kg | 3 kg | 13 kg |
| 15–30 min | 13 kg | 10 kg | 3 kg | 6 kg |
| 30–45 min | 6 kg | 7 kg | 3 kg | 2 kg |
| 45–60 min | 2 kg | 5 kg | 3 kg | 0 kg |
Scroll the table sideways to see every column.
The formula is opening stock + replenishment − requested draw. The hour total is 18 + 12 − 30 = 0 kg. Every closing value is non-negative. That looks workable until you ask when the ice is requested.
Move the withdrawals to the start of each window
For a stricter timing test, assume each window’s entire request occurs at its beginning, with production still arriving at the end. At minute 30 there are only 6 kg before a 7 kg request: 1 kg is temporarily unavailable. At minute 45, after the next 3 kg has first cleared that backlog, only 2 kg remains for a 5 kg request: 3 kg is temporarily unavailable.
These shortages are not added as four kilograms of permanently lost demand. The minute-45 replenishment first supplies the earlier 1 kg, and the minute-60 replenishment supplies the final 3 kg. The arithmetic reaches zero only because some requests wait. A bin never contains negative ice; any negative cumulative balance represents unserved demand.
| Same fictional draw and replenishment | 18 kg start | 22 kg start |
|---|---|---|
| Available at minute 30 before request | 6 kg for 7 kg | 10 kg for 7 kg |
| Available at minute 45 before request | 2 kg for 5 kg, after clearing earlier backlog | 6 kg for 5 kg |
| Unserved request at either event | Yes | None in this defined trace |
| Balance after minute-60 replenishment | 0 kg after delayed requests | 4 kg |
Scroll the table sideways to see every column.
Adding 4 kg to the assumed starting stock prevents those particular waits and leaves 1 kg immediately after the last request, before the final replenishment. It does not establish a recommended safety margin. Different bursts, losses or production timing could change the answer.
The supplier now has a useful question: can the proposed system establish and retain the required accessible starting stock and replenish it on the supported timing? If not, compare a different storage/production pairing, an appropriate backup supply or a revised operating plan. Simply choosing a higher daily figure does not identify which change fixes the trace.
Compare usable storage and the complete head/bin pairing
Ask what the quoted storage number describes and what stock can actually be available before your peak. Hoshizaki’s cited self-contained page distinguishes maximum storage from its bin-control setting. That distinction is a reason to clarify the real operating level, not permission to alter a control or pack ice above its instructed limit.
A self-contained proposal combines production and storage in its arrangement. An underbench location describes placement, not a separate guarantee of capacity or access. Assess it where the complete model meets the job and site requirements.
A modular proposal needs the production head, compatible bin and required adapter or top kit specified together. It can let production and storage be considered separately, but not every head fits every bin. Record both identities, pairing confirmation, overall height, access and all required accessories.
Show where staff retrieve ice and how that route interacts with drink preparation. Include permitted scoop storage, opening movement and cleaning access. A larger nominal bin is not useful if staff cannot reach or replenish it as intended. Do not double-allocate the same starting stock to the bar and kitchen.
The site can change the shortlist
Provide the expected room and incoming-water conditions, final position and surrounding equipment. Ask the supplier and appropriately qualified installers to assess power, water supply and treatment, drainage, heat rejection, permitted installation space and maintenance access against the actual model instructions.
Compare air-cooled, water-cooled or remote arrangements only where offered for the selected system, with their specific service requirements and whole-project implications. No condenser type wins every room. A constrained air path is a site question to resolve, not proof that a different system is automatically appropriate.
Keep drain route, levels and any proposed pump in the model-specific assessment. A pump is not a universal fix for an unsuitable installation. Likewise, choose treatment from the applicable water information and manufacturer requirements, not a universal cartridge recommendation.
Request a drawing of the full installed envelope and the route into the building. Cabinet dimensions omit the people, doors, connections and access that make the system usable.
Price the system you can operate and maintain
Separate head or self-contained machine, bin, adapters, treatment, delivery, positioning, connections, site work, commissioning and training. State AUD and the GST basis on real comparisons. This guide supplies no evergreen price or invented installation allowance.
Compare energy and water data on their stated test and operating basis. Ask which water use is included and whether the figures describe comparable equipment/tasks. Add treatment replacements, approved consumables, maintenance and the planned response to downtime using actual terms and assumptions.
Obtain the model’s cleaning, sanitising and maintenance instructions before ordering. Identify operator tasks, required training and work reserved for service personnel. Avoid a universal monthly cleaning claim or a chemical recipe copied from a different machine.
Keep model/serial details, applicable records, instructions, support route and written warranty terms together. A clean-looking bin does not establish a controlled handling process. Use the venue’s applicable food-safety procedures and establish what happens if ice cannot be supplied as planned.
Prepare the demand brief
For your own supplier brief, record actual withdrawals, usable starting stock, replenishment evidence, service timing and unmet demand. Replace the fictional inputs with actual evidence and leave unresolved decisions visible.
- Define the ice form and weigh actual recipe/task portions.
- Record withdrawals, including bursts and shared departmental use.
- Record usable starting stock and supported replenishment amounts and arrival times.
- Calculate balances and inspect individual events, not just closing totals.
- Ask for one complete, site-assessed system proposal and preserve unanswered questions.
Compare Atlantic Equipment’s commercial ice machines against that brief. Send the application, trace and site details through Atlantic Equipment enquiries. Ask the supplier to explain how the proposed system supports the peak, not merely how much it can make in a different day.
Sources and example limits
Checked 18 October 2026: Hoshizaki Australia’s ice-machine range for named ice families/configurations; the IM-45CPE-25-F product page for separate production conditions, maximum storage and bin-control fields. These are document-reading examples, not recommendations of a model or its suitability for the worked peak.
All withdrawals, starting stocks and replenishment events in the calculation are invented. No machine’s daily figure was converted into the 3 kg events. The simplified model omits losses and establishes no holding period, food safety, measured production or customer outcome. Use actual current documentation and the venue’s assessed conditions.
About this guide
Prepared by Atlantic Equipment. This guide helps buyers separate ice form, conditional production and peak storage before selecting a complete system. Its fictional event-based balance shows how an apparently adequate hourly total can still leave requests waiting. The editable brief retains timing and unresolved evidence so a supplier can assess the actual service and site.
