A commercial refrigerator is a kitchen appliance that is artificially kept cool and used to store food and drinks. Three common materials are used to build the interiors of commercial coolers:
- Stainless steel is very durable, which means it's scratch- and dent- resistant, easy to wipe clean with a cloth, and resists the growth of corroding rust, though that can form given damage or the use of caustic cleaners.
- Aluminum is easy to clean and more affordable, but it's less resistant to scratching and denting. While aluminum can corrode if damaged, the corrosion is clear, unlike rust, and actually forms a protective barrier that prevents further corrosion in that area.
- ABS plastic will not dent, scratch, or rust. Interiors made of this material are molded in one piece, with coved corners and no hard angles, so it's easy to clean and contains spills. ABS can be punctured by a hard enough blow.
Depending on how much storage space you need, the number of sections you need may vary.
- Single section refrigerators typically come with three shelves, with the option to buy more if you're storing smaller items.
- Larger boxes are split up into multiple sections, each with its own door.
If you are not storing many items a single section should suffice, but if you are running a kitchen, it's better to go with the larger one.
There are two types of doors that both have different benefits.
- Solid doors are better insulated, so they are the more energy efficient of the two under most conditions.
- Glass doors provide visibility into the box when the door is closed, which means users can see what's in each section before opening the door. If your equipment is frequently accessed, this can save energy in the long run since it could cut down on the length of time the door remains open.
Trying to store too many items in a unit that's too small can overfill the unit which may cause it to be unable to maintain safe temperatures and run the risk of breaking down.
Depending on a user application the type of unit can make a big difference.
- A roll-in unit includes a door that goes all the way to the floor and allows you to roll pan racks and other equipment inside for storage.
- A pass through unit has a door on each side so food can be passed through from one side to the other.
There are two ways to mount the refrigerator depending on your needs.
- A top mount refrigerator features split-level doors which allow you to reach into the freezer and refrigerator separately. On these models the freezer compartment side may vary.
- Bottom mount refrigerators have the freezer at the bottom, and are generally provided with a larger refrigeration portion. The freezer compartment can also have pull-out drawers, so you can see what you are looking for easily.
According to the Food and Drug Administration, your fridge should be set at or below 40 F (4 C). Your freezer should be set at 0 F (-18 C).
