Every food service business needs to have some types of ice for drinks, packing or cooling, which come in a variety of styles; crushed, dice, nugget or flake. Because of that, there are many different configurations of ice machines available today. This is why it's very important to have a better understanding about ice machines, before you make a valuable investment on an ice machine that should continually provide the precise amount of ice every time and possible never run out.
So to produce the type of ice you need, there are variations within each type of commercial ice machine, generally they fall into three basic types: Modular (head & bin combination), Undercounter and Countertop. As well as, a variations of condenser units that supplies Freon to the ice maker: Air-cooled, Water-Cooled and Quiet Cube Remote (condenser is installed outside).

Types of Ice Makers
Modular (Ice Machine Head & Ice Bin)
A Manitowoc Modular comes with the ice maker head and ice bin sold separately, for the ability to customize your setup for your specific needs. With this option you can pair up a small ice head with a large capacity ice bin for low ice demand or use a high production head with a small bin for a high ice demand.
Before you buy an ice head with an ice bin separately, need to make sure that the two are compatible with each other. Some combinations are not compatible and can not be paired at all. Yet others units may require an adapter plate between the bin and head, so be sure to do your research.
Using an adapter plate between the head and the ice bin it will ensure the units fit tightly together. This will guarantee the unit will run efficiently and prevent air from escaping, also won't leave room for dirt or pest from getting inside the ice bin, which can develop into a sanitation issues.

Types of Condenser Units
Commercial ice machine come with three types of condensers; air-cooled, water-cooled or remote. Of the three an air-cooled condenser unit is the most popular, solely because it won't drive water bill up like a water-cooled one would, and typically have a lower initial cost. However the air-cooled condenser can raise the ambient temperature in the room and generate noise during operation. But with a remote unit it will move the heat and noise generated outside, typically on the roof or anywhere outside your building, this will keep the location of the ice machine cool and quiet, and can save on energy costs by reducing AC demands.
Air-Cooled Condenser System
The air-cooled ice machine has a condenser that uses a fan to blow ambient air thru the condenser coils to remove the heat generated from the evaporator. But in order for the condenser unit to obtain a effective air flow, the ice machine requires at least 6"of clearance around all air intake and discharge area.
Water-Cooled Condenser System
Water-cooled ice machine can produce more ice using less electricity, the negative side is its high water usage. However it is not impacted by high-temperatures that may reduce the efficiency of an air-cooler ice machine nor produces any heat which won't require any additional space for air flow, also won't produce noise around the ice machine. The way it works is by pumping water through the condensing unit which will absorb the heat and carried away. Some models aren't hooked up to a closed-loop water system, so the warm water is dump down the drain, which raises your water bill, this type is being outlawed due to its waste of clean water. If a cooling tower is available, circles through the tower and runs through its own coils, cooling through exposure to the outside air before it's circulated through the system again.
Remote Condenser System
A QuietCube condenser remote unit moves the heat- and noise-generating components outside, typically to the roof or otherwise outside your building. Installing one means running refrigerant lines between it and the ice maker. This keeps inside conditions cool and quiet, and can save on energy costs by reducing HVAC demands.
Types of Ice
There are several types of ice shapes available, some easily chewable, some harder, which is good for other uses such as keeping cold food displayed safely. When choosing your ice machine there are two important factors to keep in mind: which ice shape fits your needs and how much ice you will need per day.

Ice Machine Sizing
Once you have selected the type of ice, ice machine and condenser unit, you must select the right size to meet the capacity of ice you will need. Manitowoc ice machines are available in 22", 30" and 48" widths, with ice output ranging from 250 lbs. to over 1000 lbs. per day.
Here are few other things to consider before selecting the right size and capacity of your ice machine:
- Are you a new business: When estimating the amount of ice you presently need, you also need to allow for growth to avoid the possibility of exceeding the ice machines production capacity.
- Are needing to replace your ice machine: Has the ice demand exceeded your current ice machine? If by chance your growth of ice demand has exceeded your present ice machine,
- you need to include how much you are lacking and add that to your estimate.
- Peak Time Consumption: It is always better to have extra ice available for those peak times, and any future increase in demand.
