When searching for a new ice machine, be sure to find a model that meets the capacity needs of your business. At the same time, you should avoid buying an ice maker that is too large for your needs as it may increase your electric and water bills and will lead to other inefficiencies.

As you consider different ice machines, you should figure out exactly what your business requires in terms of output and then add 20% as a buffer. For more information on choosing the right size ice machine for your commercial business, check out this ice machine sizing chart.

2. Buying an Ice Machine that is Incompatible with Your Plumbing

Because ice machines require a constant supply of water, you must choose a unit that is compatible with your business’s existing plumbing. Failure to do so can lead to undersized cubes, leaky inlet valves, or a failing grade from your local health inspector. You'll also need to place your ice maker near a floor drain, which will collect excess water. To learn more about floor drain placement and how to connect a drain to your existing plumbing, check your local building codes.

3. Buying the Wrong Type of Ice Machine

Buying the right type of commercial ice maker for your business is essential to producing enough ice during busy shifts. There are three main types of ice makers: modular, undercounter, and countertop.

Modular Ice Machines

Modular ice machines (also known as ice machine heads) are designed to sit on top of an ice machine bin, which must be purchased separately. Modular ice machines can produce between 250 and 1,000 lbs. of ice per day and are a smart choice for large foodservice establishments like cafeterias or for businesses that are packaging ice in ice bags for retail sale.

Undercounter Ice Machines

Undercounter ice machines combine an ice machine head with a storage bin. These units are designed to fit under standard 40” counters and produce around 350 lbs. of ice per day, making an undercounter ice maker machine a great choice for bars, restaurants, and hotels.

Countertop Ice Makers

Countertop ice makers are designed to sit on your countertops, so they're perfect for smaller establishments that don't have the necessary floor space for larger models. Most of them also dispense water and come with a small ice bin. These units can produce up to 400 lbs. of ice per day, making them a good choice for cafes, diners, and bars.

4. Buying an Ice Machine with the Wrong Kind of Condenser

Another important aspect of choosing an ice maker for your business is selecting a unit with the appropriate condenser. There are three main types of condensers: air-cooled, water-cooled, and remote-cooled.

Air Cooled Condenser

An ice machine with an air-cooled condenser is the most economical choice. These units use the ambient air in the room to cool down and do not require water, which will keep your water bill from going up. Keep in mind that these models require a 6” minimum clearance around their air intake and discharge areas.

Water Cooled Condenser

Water-cooled ice machines work well in smaller spaces that do not have enough clearance to fit air-cooled models. These units connect directly to your existing plumbing and are a good choice for areas where the ambient air temperature is greater than 80 degrees Fahrenheit or places where the air contains a high level of dust or other contaminants.

Remote Cooled Condenser

Remote cooled ice machines have an air-cooled condenser that is completely independent of the ice maker. These condensers are usually mounted outdoors, typically on a roof or exterior wall. Remote cooled ice machines are also quieter than their air and water-cooled counterparts due to the distance between the unit and its condenser. These products are typically used only if conditions prevent the use of water or air-cooled models.

5. Neglecting to Clean and Maintain Your New Ice Machine

Don't skimp on a water filter or descaler for your commercial ice maker machine. Spending money up front on relatively inexpensive maintenance products can potentially save you hundreds or thousands of dollars in the future. Plus, your ice will taste much better when made from clean, filtered water. Also, don't forget to clean your ice machine regularly to avoid limescale buildup and mold. You'll want to clean its water system, inspect the air filters, and check the water filtration system before thoroughly sanitizing the interior of your ice bin. Afterward, you should observe at least two cycles of ice production to ensure that your machine is completely clean.


Selecting the perfect ice machine is an important aspect of your restaurant's beverage service. With the variety of different styles and configurations out there, it's important to understand what is available To find the best product for your business. By avoiding these 5 key mistakes frequently made when purchasing an ice maker, you'll end up with a high-quality piece of equipment that will serve your business well for years to come.

  • Self Contained vs Remote Refrigeration

    Understanding the differences between self-contained and remote refrigeration is crucial when it comes to choosing the right refrigeration system for your commercial kitchen. Self-contained units keep both the refrigeration system and the storage compartment in a single piece of equipment, making them ideal for smaller spaces or mobile applications. On the other hand, remote refrigeration systems (most common for walk-in coolers) separate the compressor and condenser unit from the storage area, allowing for quieter operation and greater flexibility in design. Let's explore the key factors to consider when deciding between self-contained and remote refrigeration to help you make an educated decision for your kitchen layout and budget. Shop All Walk-In Refrigerators and Coolers What Are Self-Contained Refrigeration Units? Self-contained refrigerators are appliances that house all of their components, such as the condenser and evaporator, inside the unit itself. These types of refrigerators, walk-in coolers, and prep tables are the most popular options used in foodservice, with nearly 90% of refrigerators used in commercial kitchens being self-contained. Pros of Self-Contained Refrigeration Self-contained units are commonly used in smaller commercial spaces due to their simplicity and ease of installation. Self-contained refrigeration systems are ideal for businesses with limited space or those needing a portable cooling solution. Here are some benefits of choosing a self-contained refrigeration unit: Ease of Purchase: Everything you need to set up your self-contained walk-in refrigerator comes in one convenient purchase. Easy Installation: Self-contained refrigeration units are designed for quick and easy installation, making them a convenient choice for businesses looking to set up refrigeration systems with minimal downtime. Space Efficiency: These units are compact and self-contained, saving valuable kitchen space that can be utilized for other equipment or storage needs. Energy Efficiency: Self-contained refrigeration systems have energy-efficient options, helping businesses reduce their overall energy consumption and operational costs. Lower Maintenance Costs: With fewer components and parts compared to remote systems, refrigerator maintenance for a self-contained unit generally comes at a lower cost as they are easier to service. Versatility: Self-contained units are versatile and can be placed in various locations within a commercial kitchen or foodservice establishment, providing flexibility in design and layout options. Cons of Self-Contained Refrigeration While self-contained refrigeration units are convenient for smaller commercial spaces, they may not be suitable for larger establishments or warmer climates. Here are a few downsides to choosing a self-contained unit for your restaurant: Limited Cooling Capacity: Self-contained refrigeration systems are typically designed for smaller-scale operations, which means they may not be suitable for commercial kitchens or facilities that require high-capacity cooling. Heat Emission: Self-contained refrigeration units release heat into the surrounding environment, which can contribute to an increase in overall ambient temperature. This can lead to higher energy consumption as the unit works harder to maintain the desired internal temperature, resulting in a higher utility bill. Noise Level: Self-contained units can be louder than remote refrigeration systems due to the compressor and condenser being housed within the same unit. This can be a concern in open kitchen environments or customer-facing areas where noise levels need to be kept to a minimum. What Are Remote Refrigeration Units? Remote refrigeration units are refrigeration systems where the condensing unit is located separately from the evaporator unit. For example, the compressor and condenser of a remote walk-in cooler are typically placed outdoors or in a different area from the evaporator, such as on the roof (depending on the climate) or in a cool basement. This allows for quieter operation and better heat dissipation. Pros of Remote Refrigeration Remote refrigeration systems are ideal for commercial kitchens where noise level and heat output are a concern, as well as for spaces with limited ventilation or low ceilings. Remote refrigeration units are commonly used in larger foodservice operations such as supermarkets, large convenience stores, and commissary kitchens. Here are some key benefits of remote systems to consider: Reduced Heat Emissions: Remote refrigeration systems are located outside of the commercial kitchen or foodservice area, which means they do not release heat into the workspace. This can help maintain a comfortable working environment for staff and reduce the load on air conditioning systems. Quieter Operation: Since the compressor and condenser of a remote refrigeration system are located in a separate unit, these systems operate more quietly compared to self-contained units. This can create a more pleasant dining experience for customers and a quieter work environment for employees. Improved Energy Efficiency: Remote refrigeration systems can reduce the strain put on a compressor and condenser caused by a warm environment. If a kitchen is already warm, the unit will need to work harder to cool the items in the storage space. By placing the heat-producing components outside, remote systems can operate more energy efficiently. Alternative Installation Options: Remote refrigeration systems offer flexibility in terms of installation locations. They can be placed on rooftops, outside buildings, or in other areas that are away from the main kitchen space. This flexibility can be advantageous for businesses with limited indoor space or specific layout requirements. Scalability: Remote refrigeration systems can be easily expanded or modified to accommodate growing business needs. This scalability allows for future-proofing your refrigeration setup and making adjustments as your business expands or changes. Cons of Remote Refrigeration Remote refrigeration systems, while beneficial in many ways, also come with certain drawbacks that should be considered before making a decision for your commercial kitchen. Here are some key points to keep in mind: Installation Costs: One of the primary disadvantages of remote refrigeration systems is the higher initial cost associated with installation. These systems require additional components such as refrigerant lines, condensers, and compressors to be installed separately from the refrigeration units themselves, leading to increased installation expenses. Complexity: Remote refrigeration systems are generally more complex than self-contained units due to the need for multiple components to be installed and maintained. This complexity can lead to higher maintenance costs and potentially more frequent breakdowns, requiring skilled technicians to troubleshoot and repair the system. Space Requirements: Remote refrigeration systems require dedicated space for housing the remote condensing unit and other components, which may not be feasible for all commercial kitchen layouts. This can limit flexibility in design and may require additional planning to accommodate the necessary space for remote components. Utility Costs: While remote refrigeration systems can offer energy savings by locating the heat-producing components outside the kitchen space, they may also incur higher energy costs due to the longer refrigerant lines and additional energy needed to power the remote components. It is essential to consider the overall energy efficiency of the system to ensure cost-effectiveness in the long run. Choosing between self-contained and remote refrigeration systems depends on various factors such as space availability, noise levels, and maintenance preferences. Whether you’re opening a new restaurant or expanding your existing space, you’ll need to consider your specific needs and budget constraints when deciding which refrigeration option is best suited for your commercial kitchen.
