Buying Guide: Ice Machines

Buying Guide: Ice Machines

Ice machines are a critical component to any food service operator. There are a lot of items that are certainly big-ticket pieces of equipment when running a business, but this is definitely one of those true essentials your restaurant simply cannot operate without. Whether it is your first time purchasing an ice maker or you already have some experience, there are a few considerations to make before choosing a new ice machine for your business. With this in mind, let our ice machine buying guide help shed some light on the detailed process of buying an ice maker.

Types of Ice Machines

Undercounter Ice Machines
Modular Ice Machines
Countertop Ice Machines

The first topic to cover in our commercial ice machines guide is type. If you do not know much about the types, you may end up purchasing the wrong unit for your needs.

 

Under-counter

These machines are an all-in-one solution. They have the ice machine built into the storage bin and are ideal for small bars, cafes or businesses that don’t need as much ice. They come in a wide array of sizes, from the 15” wide residential size which holds about 25 lbs. of ice, to those that hold up to 100 lbs. Though a smaller option, these machines still require a floor drain, so if you don’t have one, you’ll need to look into a condensate pump. These are ideal for a range of businesses. While they are mostly used in smaller businesses, they can also be used behind bars and at server’s station at restaurants of any volume.

 

 

Modular:

Modular ice makers, more commonly called “heads”, are designed to sit atop a storage bin, an ice dispenser or a soda/ice dispenser. They are available in the standard widths of 22”, 30” or 48”. Depending on the installation, you might need to purchase an adaptor so that the unit will fit correctly on top of the bin or dispenser. This type of solution is ideal for when you already have a bin in place since it allows you to upgrade your ice capabilities and removes the issue of storage. Keep in mind, you may need to upgrade your bin size or adjust the production setting to make sure you maintain the right amount of ice to keep up with business.

 

 

Countertop Dispensers:

These ice machines are another all-in-one solution perfect for smaller spaces. They hold anywhere between 12 and 20 lbs of ice, with a dispenser. They usually produce nugget style ice and though they have a smaller storage bin, they can produce up to 400 lbs of ice in a 24 hour period making them great for handling high demand needs without taking up a lot of precious space.

Ice Machines Size Guide

Aside from the type, the second most important aspect we cover in our commercial ice machines guide is the size of the unit. Here are a few pointers on choosing the size.

 

Be sure you size your machine and bin to meet your peak usage needs. The amount of ice used daily is rarely uniform. Consider the fact that you will use more ice in summer than winter and weekend usage is sure to be more than weekdays.

 

Try not to base your decision solely on what your current machine does. Take into account the age and condition of your present equipment, as well as the surrounding air and water temperatures at your peak usage times. Production charts can be found on the spec sheets for each machine that will tell you 24-hour production under your particular conditions.

 

I Ideally, your company is a growing one. Consider adding 20% to your current usage estimates to account for future business growth.

Ice Types

Ice Types

Aside from type and size of the machine, the matter of ice shape is also important. Most machines are only capable of producing one shape of ice. There are several types of ice cubes to choose from. The most common are: cubes, flakes, and nuggets.

 

Cube Machines:   

Cube machines usually come with two choices in size: Half Dice or Whole Dice. You can generally find the size of the cubes by looking at the spec sheet for the machine. These machines are the most popular choice on the market. They produce a hard cube that melts slowly and provide the best drink product since it will take longer to water down the beverage, as well as keep it cooler longer.

Recommended for: Mixed Drinks, Carbonated Beverages, Ice Retailing, Salad Bars, Ice Dispensing

 

Flake Ice Machines:

These machines produce small, hard bits of ice. They cool quickly and have a low production cost. Flakes mold to any shape and are great for salad bars, hospitals, and limited specialty drinks.

Recommended for: Produce, Seafood or Meat Displays, Blended Cocktails, Salad Bars, Hospitals

 

Nugget Ice Machines:

These machines produce a softer, chewable texture ice that still provides a maximum cooling effect for drinks. In a dispenser, the ice will melt and stick together, so be sure to order the proper agitator kit to avoid any potential issues.

Recommended for: Carbonated Beverages, Blended Beverages, Salad Bars, Produce Display, Hospitals

Cooling Systems

There are also different kinds of cooling systems in place for ice machines. The two types are air cooled and water cooled.

 

Air-cooled machines 

These machines are easy to install and cost less to purchase and operate. They are affected by air temperature and incoming water temperature and require more breathing room. More environmentally friendly, the industry is turning to the air-cooled machine as the new standard.

 

Water-cooled machines 

These cost a bit more up front and are more difficult to install. They are costly to operate due to high water costs, but because they put off less hot air, they will not raise the room temperature nor do they require as much breathing room. Really, there are only 3 reasons to purchase a water-cooled machine:

  • If it will be in a small storage space
  • If the ambient air contains several contaminants (i.e. grease)
  • If the ambient air will be over 80 degrees

 

If you do go with the water-cooled model, make sure it does not violate any local water conservation laws since they tend to be less efficient on this matter.

 

Remote condenser systems 

When looking for a larger machine, you want to opt for remote condenser systems. These machines are generally reserved for larger machines, greater than 800 lbs per 24 hour. The condensing unit is usually mounted on the roof of the building to minimize the noise and heat put off. In general, the self-contained unit is the way to go. It’s easier to install and is what you will find most places.

Operating Cost – Major Brands

Manitowoc, Scotsman, and Hoshizaki are leading popular manufacturers. The operating costs of electricity and water usage vary significantly between brands. Both Manitowoc and Scotsman ice machines utilize a system that efficiently minimizes water wasted and the cost to produce ice. The cost to operate a comparable Hoshizaki unit can be substantially higher than competing brands and is not recommended. It is important to choose a machine that is not just price attractive up front, but also in the long run as well.

Reliability

Manitowoc and Scotsman machines are the most reliable in the marketplace. Available service reports rate both highly.

Other Considerations

Dimensions:

Before ordering, measure doors, hallways, and installation space to be sure your new machine will fit – allowing for 5 to 8 inches of clearance above, behind, and on both sides.

 

Connections:

Electrical and water connections and the floor drain must be within 6 feet of the ice machine. Most machines are offered in a variety of voltages to meet your requirements, be sure to order the correct voltage. All connections must meet local, state and national codes.

 

Plumbing Requirements:

Each ice machine must be connected to a cold water supply and have separate drain lines for the machine and the bin.
