In our previous article What is a cold room used for we described them in depth. Let’s do a quick recap of the important take away from the article.

A cold room is a type of refrigeration chamber or insulated space designed to maintain an artificially generated temperature or range of temperatures. Cold rooms are used for storing temperature-sensitive, perishable items, such as food items and pharmaceutical products like vaccines.

Cold rooms generally operate in two temperature ranges:

Temperature range 1  

  • The temperature is maintained between 2C and 12C in this range. It is suitable to store products that are going to be used within a few days.

Temperate range 2

  • The temperature is maintained between -2C and +5C. Such kind of temperature is suitable for products that are going to be used within a few weeks.

 We have defined what a cold room is, what it is used for and how it is used. Let’s move on and take a look at the Freezer. Remember for any cold room issues; contact Isocool pty Ltd for cold room repairs and installations in Johannesburg. You can view the areas we cover.


Walk-in freezers look very similar to walk in cold rooms but they serve a different purpose.

Walk-in freezers are capable of storing the products at much lower temperatures than a walk-in cold room. People use these freezers to ‘deep freeze’ the products at about -18C. As a result, you can use walk-in freezers to store products for a long period of time.

 Now that we have looked at both Cold rooms and freezers lets delve into the technicalities that differentiate them. Remember to contact Isocool pty Ltd for freezer repair and installation in Johannesburg and surrounding areas.


Since they offer different cold storage solutions it follows that cold room and freezers have some technical functional features that set them apart. Let’s explore them:

1. Temperature

The temperature of a walk-in freezer is lower than the temperature of a walk-in cold room. Generally, most of the walk-in cold rooms operate at a temperature range of 0°C and 5 °C. On the other hand, a walk-in freezer is capable of operating at much lower temperatures like -40°C.

Their exact temperature greatly varies on the basis of the manufacturer, so it is important that you work closely with a cold room specialist to set a suitable temperature. In Johannesburg contact Isocool Pty Ltd for this task.

2. Applications

The applications of a walk-in cold room are quite different from the applications of the walk-in freezer. The primary reason behind these differences is the temperature differences. The purpose of the walk-in cold rooms is to store the products at a low temperature above the freezing temperature.

It means you can easily use the products without defrosting. Products like fresh fruits, vegetables, medical supplies, and many other such products are stored in the walk-in cold room. You can contact Isocool Pty Ltd cold room experts in Johannesburg to install a suitable solution that will meet your specific requirement.

On the other hand, the purpose of a walk-in freezer is to preserve a wide range of products for a long period of time. Such extensive preservation is possible due to the extremely low temperatures that prevent the accumulation and multiplication of the microbes. As a result, the products are frozen in a walk-in freezer.

 3. Storage Space

There is not much difference between a cold room and a walk-in freezer in terms of the storage space. Generally, both of them have about the same space.

However, you always have the option of maximizing the storage space by customization of the cold room panels and freezer room panels. Moreover, the manufacturers also provide the option of adding space-efficient shelving units for better organization.

 4. Safety

It is important to consider the safety of the cold room and walk-in freezers because there are many products that must be protected from possible theft, such as medical supplies. Moreover, having a security system also makes sure that the products are properly secured, and no accidental contamination takes place.

Generally, you can find many cold room specialists who are willing to perform cold room installation in a safe and secure manner. Similarly, security solutions are available for freezer room panels as well. In this way, you will be able to ensure maximum security of your chosen cold storage solution.


In short, choosing a suitable cold storage solution is highly dependent on your requirements. Generally, if you want to store products at a low and moderate temperature for a short period of time, go for a walk-in cold room. On the other hand, a walk-in freezer is suitable to freeze products for an extended period.

Both walk-in cold rooms and walk-in freezers are highly important when it comes to food storage and preservation. By knowing the differences discussed above, you can easily make a smart choice and install suitable cold room panels or freezer room panels.
