Whether it’s a sweltering summer day or your employees and guests want fresh, crisp drinking water, you can quickly elevate your workplace water supply with clean ice. But, have you ever wondered how that ice is made?
Read on to learn more about the ins and outs of a commercial ice maker, along with the benefits they offer and how teams can determine the right ice machine for their unique business needs.
Most of us are aware that ice is made up of water. When cooled at a certain temperature, fresh ice is formed and kept at the same temperature to preserve it for later use. But, there’s a little more to the story than meets the eye, and delving into the gritty details of ice production is key to finding the perfect ice machine for your workplace.
A modern ice maker is composed of four primary components: the compressor, condenser, expansion valve, and evaporator. Each part of the unit is filled with a refrigerant, circulating and changing temperatures as it flows through the system. Here’s a closer look at these elements:
When it comes to ice-making, the compressor is a crucial component. By pressurizing and heating the refrigerant, this step prepares the refrigerant for rapid expansion, which occurs a little later in the process.
Condensers are the metal tubes that cool the refrigerant, transforming it from a vapor into a liquid. The refrigerant will flow through these coils to draw heat away and effectively cool the water. Finally, depending on whether you have an air-cooled or water-cooled unit, heat is expelled from the machine using air or flowing water. This lowers the refrigerant’s temperature, transitioning it from a high-pressure vapor to a high-pressure liquid.
The thermostatic expansion valve is essential for rapidly expanding and releasing pressure from the refrigerant. This process, called adiabatic cooling, results in a significant temperature drop in the refrigerant. You can think of this like when you release pressurized air from a can and it quickly cools — where a pressure shift happens that causes the liquid inside to cool as it exits the can. Rapid expansion is what turns a high-pressure liquid refrigerant into a low-pressure, low-temperature liquid during ice production.
Finally, in the ice maker’s evaporator, a water drop freezes into a solid ice cube. This happens due to the low-pressure liquid reaching the evaporator, where heat from the water transfers into the refrigerant. As water flows over the evaporator, it gradually cools until it reaches the freezing point and forms ice cubes.
Once the entire cube has frozen, your unit initiates the harvest cycle. This involves warming the evaporator using either hot gas or room-temperature water, melting the ice, and releasing it into your commercial ice bin. This way, it’s ready for use whenever you or your employees need an ice cold glass of drinking water at work.
While an ice maker is generally made up of the same four main components, there’s a slight difference in how a commercial ice maker will operate depending on the type of ice you want to offer. So, what does the ice maker cycle look like for each?
Discover the following steps involved in ice production for three main ice types:
This half-mooned shaped ice is ideal for liquid displacement in beverages and allows a glass to hold more ice — all while making drinks look fuller. Crescent ice also limits splashing when added to beverages and is less susceptible to packing together or “bridging” while being stored. This ice type is commonly used in ice bagging, soft drinks, and mixed drinks.
Ice maker steps to produce crescent ice:
Note: Some crescent systems freeze ice on both sides of the evaporator, which allows a unit to produce more ice in fewer cycles.
Also known as cubelet ice, chewblet ice, or Pellet ice, this ice type is highly popular for its soft texture that retains liquid. Because nugget ice is soft and chewable, it’s perfect for people who enjoy chewing ice, but don’t want to risk the chance of chipping a tooth. It’s preferred by bars and restaurants, like Sonic and Chick-fil-A because the small, semi-soft, nubby-textured chunks of ice are good at absorbing flavor and amplifying drinks.

Named for its rounded, cupped-shape, tulip ice is another great choice for chilling drinks. Where softer nugget ice tends to absorb the liquid for drinks and melt faster, tulip ice is more solid and takes longer to melt — so it’s less likely to dilute drinks. The rounded shape of tulip ice also provides more surface area to help cool drinks faster.

With a better understanding of commercial ice machines, their elements, and the production and refrigeration cycle, you can appreciate the intricacy of the process. Regardless of the ice type you’re after, a workplace ice maker continues the cycles above until your ice storage bin or tray is fully stocked — ensuring you have an ample supply for your employees, guests, and customers on demand.
It’s important to note that if any of the essential components or processes of your unit malfunction, you can struggle to produce enough clean ice to satisfy these individuals’ needs. This underscores the importance of regular ice maker repair and maintenance to make sure your machine is always in great working condition.
