Step 1: choose the ice type
The form of ice changes presentation, displacement, melting behaviour and how it handles in equipment. Names vary between manufacturers, so confirm the actual cube dimensions or sample.
Full or standard cubes
Clear, firm cubes are widely used for table water, spirits and mixed drinks. They tend to melt relatively slowly, but cube size and glass displacement should be tested with the venue's glassware.
Half or small cubes
Smaller cubes pack more densely and provide more contact area. They can suit fast-service beverages and smaller glassware, subject to the desired presentation and dilution.
Nugget or chewable ice
Compressed, softer ice can suit healthcare, self-service drinks and particular beverage concepts. It behaves differently from hard cube ice and may require a purpose-built dispenser.
Flake ice
Flake ice is commonly used for food display, seafood, produce, clinical or production applications. It is generally selected for coverage and mouldability rather than premium beverage presentation.
Gourmet or specialty shapes
Large, slow-melting or visually distinctive shapes can support premium drinks. Output, storage and cost per serve may differ substantially, so test the commercial requirement.
Browse the available commercial ice machines only after defining the required form; a machine producing the wrong ice is not rescued by spare capacity.
Step 2: calculate real demand
Build demand from actual uses:
- beverage ice per serve multiplied by peak serves;
- water stations, bottles or table service;
- food display or production ice;
- blended drinks;
- staff or back-of-house use;
- expected waste, melt and transfer losses;
- unusual peaks such as functions, weekends or hot weather.
Record demand by hour as well as by day. If a venue consumes most of its daily ice in a two-hour period, the bin must hold enough before service and the machine must recover before the next peak.
Planning demand = measured peak use + verified operational buffer

Planning demand:
Avoid a universal percentage buffer. The right allowance depends on seasonality, delivery alternatives, storage limits and the cost of running out.
Step 3: interpret daily output honestly
Ice production ratings are measured under stated air and inlet-water conditions. Warmer air, warmer incoming water, scale, blocked ventilation or poor maintenance may reduce output. Compare manufacturers using equivalent rating conditions and obtain performance data relevant to the site.
Ask:
- What air and water temperatures support the published output?
- Is a lower output shown for warmer conditions?
- How does the selected condenser reject heat?
- What clearance and ventilation are required?
- Is the bin included, integrated or selected separately?
Do not design from nominal output alone. A correctly sized machine in a poorly ventilated cupboard may still disappoint.
Step 4: size storage and recovery together
An ice bin is a buffer, not a freezer designed to hold ice indefinitely. The machine cycles to replenish ice while the bin stores production for peak withdrawal.
Consider:
- ice needed at opening;
- largest peak draw;
- hours available to produce before that peak;
- turnover needed for hygiene and freshness;
- bin footprint and door clearance;
- safe reach and scoop handling;
- whether a separate dispenser is required.
An oversized bin with low turnover creates cleaning and handling problems. An undersized bin wastes production opportunity and may leave the venue short during service.
Step 5: audit the installation site
Potable water and water treatment
Ice for consumption is food. Queensland Health guidance states that it should be made from drinking-quality water. Confirm water quality, pressure and connection requirements. Filtration or treatment may improve taste, clarity and equipment protection, but the correct system depends on local water and manufacturer requirements.
Drainage
Confirm drain type, fall, air gap or tundish requirements, pipe route and local plumbing rules. A floor waste near the machine does not prove the proposed connection is compliant or will drain reliably.
Ventilation and ambient heat
Keep the machine away from avoidable heat sources and provide the specified clearances. Queensland guidance recommends good ventilation and separation from appliances that generate heat.
Electrical supply
Check the exact voltage, phase, current and connection. Use the single-phase vs three-phase guide to frame questions, then have a licensed electrician verify the site.
Access and hygiene
Staff need safe access to the bin, scoop and removable components. Service technicians need access to filters, panels, condenser and water system. Avoid a position exposed to splash, grease, dust or customer contamination.
Air-cooled, water-cooled or remote condenser?
Air-cooled machines reject heat into the surrounding space and need clear airflow. They are common, but room temperature and ventilation matter.
Water-cooled models can reduce heat discharged into the room but consume condenser water and may be constrained by water cost, sustainability goals or local rules. Do not assume they are permitted or appropriate.
Remote condensers move heat rejection away from the machine but add design and installation complexity. Compare the exact system with qualified refrigeration and plumbing advice.
Food-safety controls for ice
Queensland Health recommends keeping the machine inside clean premises, following the operating manual and implementing a cleaning schedule. Ice should be handled with a clean scoop stored hygienically—not with glassware or bare hands.
At minimum:
- use potable water;
- follow the manufacturer cleaning and sanitising procedure;
- clean the bin, scoop and applicable food-contact parts;
- inspect for slime, scale, odour or foreign material;
- keep the lid closed;
- document cleaning and service;
- discard contaminated ice and investigate the cause;
- arrange professional maintenance at the specified intervals.
The final schedule should reflect the machine, water conditions, usage and food-safety program. Do not publish a generic chemical concentration or dismantling method.
Compare total operating cost
Purchase price is only one component. Compare:
- production and storage capacity;
- energy and water use under comparable standards;
- replacement filters and treatment consumables;
- cleaning labour and access;
- planned service;
- condenser heat and ventilation impact;
- warranty terms and local service availability;
- cost of buying emergency ice during downtime.
For beverage-led venues, also explore commercial beverage equipment. For an integrated layout, ProChef's commercial kitchen design service can coordinate equipment and workflow with the relevant trades.

Frequently asked questions
How many kilograms of ice do I need per day?
There is no safe universal figure. Measure each use, model the busiest period and apply an operation-specific buffer. Glass size, drink program, climate and service style materially change demand.
Is the rated output what I will always receive?
No. It is tied to test conditions. Site temperature, inlet-water temperature, ventilation, scale and maintenance can affect production.
Does an ice machine need a floor drain?
It needs drainage configured to the manufacturer's instructions and local plumbing requirements. The exact arrangement is site-specific; use a qualified plumber.
Can staff scoop ice with a glass?
No. Glass can break and hands can contact the ice. Use a dedicated clean scoop and store it hygienically.
