THE SCOOP ON ICE MACHINES
Restaurants and commercial kitchens go through tons of ice. Especially in the summer months, when thirsty customers expect cold drinks, a dependable ice machines is a staple appliance. Whether purchasing a new or replacement model for the first time, kitchen managers have much to consider in selecting the right machine for their spaces.
The two critical considerations for choosing a suitable unit boil down to the following:
- How much volume of ice will my kitchen go through regularly?
- What type of ice does my kitchen need?
Types of Ice Machines
There are three kinds of ice machines commonly in use in commercial settings:
Floor-standing models (aka modular ice machines)
These units produce a lot of ice. Most commercial kitchens can rely on a floor-standing unit to produce enough ice for their entire facility (or at least be the primary source of ice). The amount of ice made is constrained by the size of the ice bin or dispenser type, so keep the storage in mind when comparing models.
The following two categories are self-contained, meaning they already have built-in ice storage bins:
Undercounter commercial ice machines
As you would expect from the name, these units fit in tight spaces and under counters. These models are best as a secondary source of ice. They provide quick access to ice in bars, prep stations, and other areas where space is a premium.
Countertop ice machines
These units fit on countertops and are appropriate for relatively low-volume ice usage. Countertop machines are a good fit for healthcare settings and self-service environments like cafeterias. Many models feature touch-free options and built-in antimicrobial components to avoid cross-contamination.
Ice Production
Ice production measures the total amount of ice that a machine can make within 24 hours. This metric assumes that air temperature is 70°F and that water temperature is 50°F, which are optimal for most ice machines. Warmer air and water temperatures lower the total amount of ice produced. Additionally, this number doesn’t always consider the size of your ice bin. Smaller bins means less total ice made.
As a rule of thumb, assume that the real-world ice production of a machine will be 85% of the manufacturer’s measurement.
In general, modular ice units can produce anywhere from 45 – 3000 lbs of ice per day, while self-contained models have a more modest range of 60 – 300 lbs.
Types of Ice
Each type of ice has specific applications.

Other considerations
Placement
A majority of commercial ice machines are air-cooled. Most models need six to eight inches of space around them to vent hot air. Water-cooled units can fit tighter spaces but require a constant water flow, which can lead to excessive water bills, especially in the summer.
Maintenance
Once you’ve selected the perfect ice machines for your establishment, regular cleaning and maintenance are crucial to protecting your investment. A rule of thumb is to schedule cleaning and maintenance from a certified technician at least twice a year.
