Nearly every type of food service business needs an ice machine. Because there are so many different configurations and styles available, it's important to understand what is available, and what will work best for your business' needs.
While there are variations within each type, commercial ice machines generally fall into three basic styles.
Modular ice machines are commonly available in 22", 30" and 48" widths, and are designed to sit on top of an ice machine bin, an ice machine dispenser, or a soda dispenser. Ice outputs range from 250 lbs. per day to well over 1000 lbs. per day.
For small bars, cafes, or businesses that don't need as much ice, an undercounter, or self-contained ice machine may be all that's needed. They combine the ice machine with a storage bin, and fit under most 40" high counters. Ice outputs generally top out at about 350 lbs. per day, though a few higher capacity models do exist.
These compact units are often found in health care settings, and may dispense water too. They have a small bin but can still produce up to 400 lbs. of ice per day. They also usually dispense nugget style ice, which is easier to chew.
Understanding the different types of ice that commercial ice machines can produce will help you choose the right type for your needs.
- Most common; melts slower and can potentially reduce customer ice consumption compared to other types
- "Full" (approximately 7/8" x 7/8") cubes
- "Half" (half of full) cubes
- "Regular" (approximately 1 1/8" x 1 1/8" x 7/8") cubes
- Slow melting; most common in health care industry because it's softer and easier to chew than cube ice
- Also called compressed nugget, or "chewblet" ice
- Small, soft flakes of ice that cool rapidly and mold to any shape
- Used mainly in ice displays for seafood, meat, fish, and on salad bars; can also be used in blended drinks
Once you've decided what type of machine and ice you want, the next important consideration to make is whether you want an air-cooled, water-cooled, or remote compressor.
Air cooled ice machines are often the most cost-effective type of ice machine, as they do not involve any additional water costs. Many air cooled models even achieve Energy Star Compliance. Air cooled condensers do need at least 6" of clearance around air intake and discharge areas, but they are a good choice for the majority of users.
A water cooled ice machine is a better choice than an air cooled model only if one or more of the following conditions exists:
- The machine would be installed where ambient air temperatures are greater than 80 degrees Fahrenheit
- The machine would be installed in an area where the air contains a high level of contaminants, like grease
- The machine would be installed in an area with poor air circulation or limited space where clearance limitations of an air cooled machine could not be met
Again, unless one or more of the above conditions exist, a water-cooled machine is probably not the best choice, since water consumption will be much higher than with an air cooled ice machine. In fact, some municipalities do not even allow the use of a water cooled ice machine for that reason!
With remote condenser ice machines, the condenser is air cooled, and mounted outdoors, usually on a roof. Refrigerant lines run between the condenser and the machine. As a result, a remote condensing ice machine will be much quieter than its air or water-cooled counterparts.
However, installation and maintenance of a remote setup can be much more costly, and a remote condenser ice machine is usually only chosen if conditions prohibit the use of an air cooled or water cooled unit.
Ice Machine Sizing
Once you've settled on the type of ice machine you need and the type of ice you want, you must select a machine with the right capacity for your needs.
- For new businesses: Make sure your estimates allow for growth, or you could quickly exceed the production capacity of the machine you wish to purchase.
- For replacement ice machines: Did your current ice machine keep up with demand? If not, you will need to evaluate how much capacity you were lacking and factor that into your calculations.
- For everyone: Ice consumption at peak times should be considered, as well as any possibility for a future increase in demand. It's always better to have extra ice on hand than to rely on a machine that is too small to meet your needs.
Benefits of Using Multiple Ice Machines
It may seem easier to supply all your ice from one large machine and bin, but in the end this is usually inefficient. With only one large machine, your staff will constantly be running back and forth from the ice bin to soda machines, under bar ice chests, and salad bars…costing you time and also increasing chances of cross-contamination.
Instead, consider using several smaller machines, one on top of the soda machine, a small underbar unit, and a small ice machine with a bin near your salad bar, for example. This way your staff will always have ice when and where they need it, while also keeping the ice safe and sanitary!
- Space and Placement: Make sure you have enough space for the machine, bin, and filter. Adequate air flow is crucial for maximum ice production. Carefully considering the placement of the machine and bin can also increase worker productivity and efficiency.
- Water Supply & Floor Drain: Your ice machine will need a cold water supply with a shutoff valve. A floor drain is needed too. Check your local codes for specific drain type and placement requirements.
- Power Supply: Many ice machines do not come with a cord and plug, so a visit from your electrician will be needed to hard wire the machine. Make sure you understand and can meet the machine's power requirements—not all machines operate on standard 110V electric. Electrical requirements and any other special installation considerations will always be found on the machine's Specification Sheet.
Use the chart below to get an idea for how much ice you might use. It's also important to keep in mind that ambient room temperature and ventilation considerations will affect the maximum output of any ice machine. This information is usually available on the manufacturer's Specification Sheet.

Ice Machine Bin Sizing
An ice machine bin lets you hold ice until it's ready for use. When picking a bin to go with your modular ice machine, you'll want to take several points into consideration:
- Choosing a bin / machine combination that's too large will result in wasted ice, and the melt water can make the bin a breeding ground for bacteria and mold.
- Choose a bin / machine combination that's too small, and you'll be constantly running out of ice, and taxing your machine as it struggles to keep up.
- Don't assume the bin has to match the capacity of your machine. If your restaurant is busiest on the weekend, for example, you might need 900 lbs. of ice, but not nearly that much during the week. Pairing a small ice machine with a large bin will ensure you don't over-produce during the week, and that you'll still accumulate enough ice to handle the weekend rush.
You can find compatible bins in the Companion Items of most of our modular ice machines.
To prolong the life of your ice machine and increase your customers' satisfaction (remember, ice is food), we recommend using a water filter with every ice machine, because it will reduce the buildup of mineral deposits within the machine. The benefits of using a water filter with your unit cannot be understated, but here are just a few:
- Better tasting beverages
- Higher ice production
- Lower energy usage, since the ice machine can work more efficiently
- Longer ice machine life
- Poor quality feed water will VOID THE WARRANTY on most ice machines
We offer two sizes of ice machine filter kits that will work with all the ice machines we carry. They are located in each machine's Companion Items.
An ice dispenser is similar to a bin in concept - it holds ice until use but it eliminates human contact with the ice supply by using a sensor or lever dispenser system. There are two basic types:
- Hotel Dispensers: A modular ice machine is mounted on top and the dispenser holds the ice. This lets guests get ice at their leisure and you don't need to worry about them contaminating the ice with hands, cups, etc. We even offer several models that are coin operated, while room-key operated models ensure that only customers use your ice.
- Countertop Dispensers: These are most common at nurse stations and other healthcare applications due to their compact size, and many also dispense water, too. We offer two types, ones that include a built in ice machine and models that require the ice be loaded manually.
Bin adapters are used in several situations.
- Installing one or more small ice machines on a big bin
- Installing an ice machine on top of an ice dispenser
- Installing one brand of ice machine on a different brand of ice machine bin
Keep in mind that many more types of adapters are available for very specific situations, and are often listed on the manufacturer's Specification Sheet. Depending on your application, you may also need an ice deflector in place of or in addition to the adapter.
Ice Machine Cleaner
Even with the proper filter kit your machine will still gradually accumulate mineral deposits on the interior, harming performance and efficiency. Our Noble Chemical Arctic ice machine cleaner is safe for use in all ice machines and will remove these buildups, while also protecting tin and nickel-plated evaporators! The Arctic cleaner is available in both a concentrated cleaner and a ready to use formula.
A heat exchanger uses cold waste water from your ice machine to pre-chill potable water entering your machine. Because the water is already cold, your unit spends less energy making ice, which cuts costs and allows more efficient operation. Compatible heat exchangers are listed in the Companion Items of our ice machines.
If you plan on selling bags of ice, a bagger kit may be a worthwhile investment. For small-volume applications, we offer frames that fit right over the ice bin door opening and funnel ice down into the bag. Or, for very large-scale use where you'll be packing and selling lots of ice, we offer units specially designed to store and load the product.
Other Must-Have Accessories
These two products go hand-in-hand. To stay in accordance with health and sanitation regulations, use these items to transport ice from the bin to other locations around your establishment, and make sure your employees use them, rather than cups or hands.
