Commercial Refrigeration

There are major differences between domestic and commercial fridges, and you shouldn’t make the mistake of thinking that a domestic appliance can do the job of an industrial fridge.

The main difference is that an industrial fridge or cold room such as you would find used for cold food storage for pubs, restaurants, cafés or hotels is designed to be opened and closed continuously, and will maintain its temperature in those conditions, while a domestic appliance is designed to remain closed most of the time and to be opened only very occasionally and for short periods. Brands such as Polar, Fagor, Blizzard and Foster Refrigerator specialize in this sort of design and will give the necessary technical support.

But how do these requirements actually affect the design of industrial refrigeration units?

Commercial refrigeration units are designed with high-power compressors which can reduce temperature quickly. They will also in most cases be fan assisted, helping them to distribute the optimal temperature throughout their interior. This does mean that they are likely to make more noise than a domestic appliance, one reason why a commercial fridge will not be suitable for a domestic role.

The door designs of commercial fridges such as a Foster Walk In Fridge will also allow them to be opened and closed many times throughout the day without suffering the wear and tear which would affect a domestic appliance.

How Does Commercial Refrigeration Work?

All commercial refrigerators and domestic units work on the same physical principle, the Second Law of Thermodynamics, which states that when two objects of different temperatures are brought together, heat will travel from the hotter to the colder. This principle is used to transfer heat from food stored in a commercial or domestic refrigerator into a refrigerant liquid.

This liquid obeys another physical law, which is that when it expands and becomes gas, it cools, losing the heat through the industrial refrigerator unit’s cooling system. The closed cycle of heating and cooling of the refrigerant acts to keep the food inside cold and preserved, while the refrigerant liquid, originally Freon and now more commonly tetrafluoroethane, should last indefinitely if the system is properly maintained.

What Are The Different Types Of Commercial Refrigeration?

There are several different types of commercial or industrial refrigerator, and you should select one according to the requirements of your business. A restaurant or café will probably need a chiller, an oversized walk-in refrigerator unit such as a Foster Walk-In Fridge, and deep freezers for large amounts of food and drinks, while a bar may require more in the way of specialized wine and beverage wine coolers.

When buying an industrial refrigerator, go for the largest size manageable, while allowing space for ventilation for the compressor. Ventilation can be at the bottom, side or top or the unit, so you aren’t necessarily restricted in your product choices by ventilator position.

A bar refrigeration unit for instance will often be placed behind the bar, with front ventilation and glass doors, making it possible for customers to see the available wines and beers, and for bar staff to keep an eye on stock levels of drinks. An alternative is the top-loading bottle cooler, which offers storage and easy access for larger numbers of bottles. Bar refrigeration units are also available to chill glasses and plates. Small under-counter chillers, refrigerators and freezers can still offer the power required of a commercial unit, providing handy storage of drinks while acting as a complement to a larger kitchen unit.

In a retail setting, a large number of bottles or cans may be stored in a refrigerated merchandising unit, serving the dual purpose of storage and display for a café.

In the commercial kitchen, whether for the preparation of simple meals such as sandwiches or more complicated dishes like pizza, a prep table combined with a refrigeration unit is a popular type of mobile industrial refrigeration unit. Often offering a wide temperature range, these units are very flexible in their applications.

While commercial reach-in fridges may come with many options including glass fronts, double doors, dual-temperature zones and movement on castors, the ultimate refrigerator unit for many businesses will be the walk-in type, or cold room, often of modular design for easy disassembly, and supplied with internal shelving, lighting and non-slip flooring.
