Cold storage systems for warehouses are now in high demand considering the increasing volumes of medical, chemical and food supplies to be stored. This type of inventory is not to be stored in a standard warehouse because of its sensitive storage conditions. Only a few facilities are considering installing such systems instead of outsourcing. Finding suitable cold storage systems would help businesses streamline operations and improve their bottom line. 

Here is a comprehensive guide to help warehouses understand their cold storage options:

Cold Warehouse

A cold warehouse is a facility or building that stores temperature-sensitive products to maintain their properties. These warehouses are built like any other storage facility, only that they have additional temperature control mechanisms.

Types of Cold Storage Warehousing

Two main elements make up the cold storage systems of a warehouse. These are the external structure and the equipment. The main factor that combines these two elements is the usage of storage racks. Regardless of warehouse construction, all cold storage systems have a role to play in the internal space at controlled temperatures. 

Cold storage systems are either:

• Refrigerated controlled temperature from 0 to 10°
• Fully frozen with temperatures from -30 to 0°

Each type of cold storage system has its purpose. A refrigerated cold storage system is used mainly for foot products to maintain them at optimum temperatures and prevent spoilage. On the other hand, fully frozen cold storage systems store products at constant stable temperatures to minimize the risk of damage.

Cold Storage Warehouse Equipment

Considering products in a cold warehouse are sensitive to temperature changes, these facilities have sensors for controlling the internal temperatures. First, some dehumidifiers are installed to reduce the formation of ice. Secondly, they use airlock systems that maintain consistent temperatures since the warehouses are constantly opened and closed.

Storage Racks

– Mobile Pallet Racking

Regarding storage solutions, cold warehouses use mobile pallet racking because the system maximizes space efficiency. This system allows only one operation aisle, allowing warehouses to save 40% floor space more than conventional racking. A mobile rack also increases storage capacity by more than 80%. These systems also allow quick forklift access to minimize exposure to cold conditions.

– Shuttle Racking

Shuttle racking is an ideal cold storage solution for fully frozen facilities. Given the significantly lower temperatures, they do most of the work to prevent the risk of hypothermia. Shuttle racking also works better for high-density storage, notably smaller range products like pharmaceuticals. The built-in shuttle carries the pallets from the loading area and transports them along the racking bays. Depending on daily operations, this is the perfect option for FIFO or LIFO inventory management.

– Pushback Racking

Pushback storage solutions are more compatible with LIFO inventory management. This cold storage rack has roller beds and cards built within the racking. When loading one rack, the others are pushed back, and when one pallet is removed, the others roll forward for easy retrieval. All operations occur on one side of the block, minimizing the need for a forklift.

In summary, these storage systems are ideal because they reduce the amount of refrigeration required per square footage. They perfect for increasing energy efficiency by saving on energy costs. As the cold logistics industry grows, it is paramount that warehouses prepare adequately for increasing business volume. Working with warehouse racking manufacturers helps businesses find the perfect solutions.
