Depending on the temperature range at which the cold rooms operate, there are types of cold rooms:


Storage cold rooms

Chillers are designed for the conservation of products between 0 and 10 ºC. They are mainly used for the preservation of fresh food, beverages or medicines.


Walk-in chillers are a best friend when it comes to storing perishable items. This invaluable storage equipment is vital for several commercial applications, including food and beverage, hospitality, and even events catering.


They maximize the shelf life of your products, ingredients, and materials, and they offer improved energy efficiency over conventional refrigerators. And with many different size options available on the market, they are a versatile refrigeration solution for any business.

Freezing cold rooms

Freezers are used to keep frozen products between 0 and -28ºC. They usually have better insulation and fewer daily openings. Frozen food, vaccines, or organic material are kept at these temperatures.


We offer several sizes, brands, and models that are all suited for serving different purposes.A large industrial walk-in freezer is the ideal solution if you manage a large business, such as a distribution center or manufacturing plant.The largest type of walk-in freezer is the industrial walk-in freezer, which is designed for warehouses or other large commercial operations. These units typically have multiple doors and are always chest models.


Blast Freezers

Simply put, a blast freezer is just a freezer which is very cold. Blast Freezers are sometimes referred to as shock freezers. The idea of this type of freezer is to very rapidly bring down the temperature of (usually) foodstuffs or fresh produce, freezing them very quickly.


Why freeze fast? When you freeze food (or anything else for that matter) the water inside crystallises into ice.


They are widely used in the frozen food industry for things like iced cream, pre-prepared meals and vegetables or fish. A lot of commercial kitchens also use them for some things.



If you’re looking for a commercial or industrial refrigerator, there are a few things you need to know. Freezers and chillers not only do they maintain the quality of your stock, but they can also help you save money in the long-run. Here are some reasons why you should invest in a refrigerator:
