Commercial Ice Machine Buying Guide 

 How to Choose the Right Ice Maker for Your Business 

Choosing the right commercial ice machine can make a real difference to your day-to-day operations. Whether you're running a busy pub, restaurant, café, hotel or food retail business, having a reliable supply of ice helps you serve customers efficiently and maintain consistent standards.

With different ice types, production capacities, storage options and cooling systems available, it's important to choose a machine that suits your business rather than simply buying the largest or cheapest model.

At DS Refrigeration, we supply commercial refrigeration and catering equipment to businesses across Northern Ireland, Ireland and the wider UK. This guide explains what to consider when buying a commercial ice machine, helping you understand your options and make an informed decision.

In this guide, we'll cover the different types of ice, how much ice your business might need, which features to compare, installation requirements, running costs and ongoing maintenance.

 1. Why Does Choosing the Right Ice Machine Matter? 

A commercial ice machine is an important investment for businesses that rely on ice throughout the working day. Choosing the right equipment helps you meet customer demand while managing operating costs and making the best use of your available space.

The right machine can help you:

  • Maintain a reliable supply of ice: Avoid running short during busy services and peak trading periods.
  • Improve service efficiency: Make ice readily available for drinks, food preparation and display.
  • Manage running costs: Match production capacity to your actual requirements to avoid unnecessary energy and water consumption.
  • Maintain hygiene standards: Choose equipment that can be cleaned and maintained properly.
  • Make better use of space: Select a countertop, undercounter or modular machine that suits your premises.

Buying a machine that is too small can leave your team struggling to meet demand. However, a machine that is unnecessarily large may increase purchase costs and use more resources than your business needs.

The goal is to find the right balance between production capacity, storage, available space and budget.

 2. Which Type of Ice Do You Need? 

Before choosing an ice machine, consider how your business will use the ice. Different ice shapes and sizes are suited to different applications, so the right choice depends on whether you're serving drinks, preparing food or displaying chilled products.

  •  Cube ice 

    Cube ice is a popular choice for pubs, bars, restaurants and cafés. Its relatively slow melting rate makes it suitable for chilling drinks while helping to limit dilution.

    Depending on the machine, you may be able to choose between full cubes, half cubes or smaller, flatter cubes.

    Best suited to: Pubs, cocktail bars, restaurants, hotels and general beverage service.

  •  Half cube & flat ice 

    Smaller ice cubes offer a larger total surface area for a given quantity of ice, helping drinks cool quickly. Flat ice is particularly useful in fast-paced beverage service where rapid cooling and consistent portioning are important.

    Best suited to: Bars, cafés, hotels, fast-food restaurants and self-service beverage stations, depending on the ice shape produced.

  •  Nugget ice 

    Nugget ice, also known as cubelet or chewable ice, is made by compacting smaller pieces of ice into soft nuggets. It is useful for applications where easily chewable ice and rapid cooling are desirable.

    Best suited to: Selected healthcare settings, beverage stations, cafés and businesses serving blended drinks.

  •  Flake ice 

    Flake ice consists of small, soft pieces that can be spread and shaped around products. It is particularly useful for chilled food displays, where it helps present products such as fish and seafood on a bed of ice.

    It can also be used in certain food preparation and blending applications.

    Best suited to: Fishmongers, seafood counters, food displays, delis and other food retail environments.

  •  Scale ice 

    Scale ice is another option for food display and cooling applications. Like flake ice, it is used where ice needs to surround or sit closely against products.

    The precise characteristics and suitability will depend on the machine and the intended application.

    Best suited to: Specialist food display and commercial cooling applications.

Our advice: Start with the intended use of the ice, then choose a machine that produces the appropriate shape and quantity. Not every ice machine produces every type of ice, so always check the product specifications before purchasing.

 3. What Type of Commercial Ice Machine Should You Buy? 

Once you've identified the type of ice you need, consider the machine's design, production capacity and storage arrangement.

Countertop ice machines

Countertop models are designed to fit on a suitable worktop or counter. Depending on the model, they may use a manual-fill system or require a water connection.

They can be useful where space is limited or ice demand is relatively modest.

Undercounter ice machines

Undercounter machines are designed to fit beneath a suitable counter or work surface. Many combine ice production and storage in one unit, making them a practical option for businesses where floor space is limited.

Consider an undercounter machine if: You need ice close to the bar or preparation area without dedicating space to a larger freestanding unit.

Always check the machine's dimensions, ventilation requirements and available clearance before choosing an installation position.

Self-contained or integral ice machines

A self-contained machine combines the ice-making mechanism and storage bin in a single unit.

This can simplify equipment selection and installation planning, particularly for businesses with light to moderate ice demand.

When comparing models, check both the daily production rate and the amount of ice the built-in bin can hold.

Modular ice machines

Modular systems separate the ice-making head from the storage bin. This allows production and storage capacity to be selected according to the requirements of the business.

They can be suitable for higher-demand operations, including larger pubs, hotels, restaurants and catering facilities.

Remember that the ice-making head and storage bin must be compatible, and the complete system must fit your available space.

Ice and water dispensers

Some businesses benefit from dispensing ice directly to customers or staff. Ice and water dispensers can be suitable for self-service beverage stations, hotels, workplace facilities and other locations where convenient access is important.

Check the dispensing method, output, storage capacity and intended application before choosing a model.

 4. How Much Ice Does Your Business Need? 

Production capacity is one of the most important factors when buying a commercial ice machine.

Machines are commonly rated by how much ice they can produce over a 24-hour period, usually expressed in kilograms per day. However, the amount produced in practice depends on operating conditions, including ambient temperature, incoming water temperature and the machine's installation.

Your daily ice requirement will depend on your business type, customer numbers, menu and busiest trading periods.

Indicative ice demand

The following figures from the buying research can be used as an initial reference, not as guaranteed requirements for every business.

Business Type Indicative Ice Requirement
Restaurants Around 0.68 kg per customer
Bars Around 1.36 kg per customer
Hotels Around 2.27 kg per guest
Food displays Around 13.6 kg per cubic foot of display

These are broad estimates from the source material. Actual demand can vary considerably depending on how the ice is used, the number of drinks served, the size of portions and the type of food display.

For reference, 1 lb is approximately 0.45 kg.

How to estimate your requirements

Start by considering:

  • How many customers do you serve on a typical day?
  • How many drinks require ice?
  • How much ice is used per drink or serving?
  • What is your busiest service period?
  • Does your business experience seasonal increases in demand?
  • Will you use ice for food preparation or display as well as drinks?

For example, a cocktail bar serving a large number of iced drinks may need a higher production rate than a café that uses ice occasionally.

Allow some flexibility for unexpected demand and seasonal peaks, but avoid buying significantly more capacity than you need.

Production capacity vs storage capacity

These are two different specifications, and both matter.

Production capacity is the amount of ice the machine can make over a stated period, typically 24 hours under specified test conditions.

Storage capacity is the amount of ice the bin can hold at one time.

A machine might produce enough ice over 24 hours but still struggle during a concentrated lunchtime or evening rush if its storage bin is too small.

For a modular system, check that the storage bin can accommodate the amount of ice you need between services. For a self-contained machine, consider both specifications together.
