How do cold storage warehouses operate?

Cold storage warehouses are insulated warehouses that maintain a cooling temperature. The insulation helps minimize the transfer of heat from the surroundings to maintain the warehouse’s cold temperature. The refrigeration units used in these kinds of warehouses are like giant air conditioners that use coolant to absorb the heat inside then release it outside. it continuously repeats the cycle to meet the desired temperature.



Types of Cold Storage Warehouses:

There are various types of cold storage warehouses in use today. They differ from one another in terms of their use and application. The following are some of the more common types:

They prevent the growth of bacteria while keeping the quality of the items stored and at the same time, extend the items’ shelf life. Food processing businesses, ice cream companies, and pharmaceuticals are the ones who mostly use these units.


4.     Ultra-low Temperature Cold Storage 

Commonly used to store sensitive products that degrade in high temperatures. This type of cold storage operates at temperatures ranging between -41°F to -129°F which is ideal for storing laboratory samples, pharmaceutical products, and other materials used for research.

Key Features of Cold Storage Warehouses:

These are the components that make cold storage warehouses ideal for the preservation of food, medicine, and other valuable products.


Insulated Walls and Floors:

 Materials such as foam or fiberglass make up the insulation of the walls and flooring. They aid in minimizing the transfer of heat while maintaining the cold temperature inside.


Refrigeration System:

This is made up of several important components such as the condenser, compressor, evaporator, and fans that work continuously and in harmony to allow cold air to circulate in the warehouse.


Temperature Monitoring System:

Made up of a series of temperature monitors and alarms that notify the personnel when malfunctions or problems concerning the temperature occur within the warehouse.


Airtight Construction

Since cold storage warehouses need to keep the cold air circulating inside, the building or warehouse doors, windows, and any other gaps that may allow hot air to enter are sealed.


Humidity Control System:

The quality of the items stored inside the warehouse is one of the most important things to consider which is why humidity control systems are installed to prevent excessive moisture from accumulating that may affect the stored products’ quality.

Chilled Storage

Chilled storage is used when products need to be kept in cool, but not freezing temperatures. Fresh produce like dairy, fruits, vegetables, cosmetics, and beauty products are the items commonly kept in this type of storage to prolong their quality and freshness.


Frozen Storage

For long-term preservation, frozen storage is the way to go. The working temperature is between 0°F to -20°F which prevents most bacteria from growing. Products like meat, poultry, and ice cream are some examples of items that need to be stored and frozen. In some cases, vaccines and medicines are also stored to prolong their effectiveness. Laboratories use frozen storage to keep plasma, tissues, and other research materials.
