When it comes to the cold storage industry, businesses often face the dilemma of choosing between a traditional cold room and a container cold room, such as a reefer container. Understanding the key differences between these two solutions is crucial for making an informed decision that suits your business’s needs. This blog will explore the features, benefits, and distinctions between cold rooms and container cold rooms.
What is a Cold Room?
A cold room is a large, insulated space designed to store temperature-sensitive products such as food, pharmaceuticals, or chemicals. Typically, cold rooms are permanent installations within buildings and come in various sizes, from walk-in fridges and freezers to large industrial cold storage rooms.

Key Features of Cold Rooms:
- Permanent Installation: Cold rooms are built-in and can’t be moved once installed. They are custom-made to fit the space and specific refrigeration needs of the business.
- Variety of Temperatures: Cold rooms range from cold storage rooms that maintain a temperature just above freezing to freezer rooms and walk-in refrigerators that can hold much lower temperatures.
- Cold Room Refrigeration System: Advanced cooling systems are integrated into cold rooms to ensure consistent temperature control and humidity management.
- Walk-In Chillers and Freezers: Cold rooms often feature walk-in chillers and freezers for easy access to stored items.
Cold rooms are ideal for businesses that need to store large quantities of perishable products in one location and are often used in restaurants, warehouses, and hospitals.
What is a Container Cold Room (Reefer Container)?
A container cold room, also known as a reefer container or refrigerated shipping container, is a portable cold storage solution that is designed to store and transport temperature-sensitive goods. These refrigerated containers are typically used for shipping perishable items across long distances but can also serve as temporary cold storage units.

Key Features of Container Cold Rooms:
- Portable and Flexible: One of the main advantages of container cold rooms is their mobility. Reefer containers can be moved from one location to another, offering flexibility in storage solutions.
- Shipping-Grade Durability: These containers are built to withstand the rigors of transportation and are designed to protect goods in transit from temperature fluctuations, weather, and damage.
- Cold Room Container Options: Container cold rooms come in different sizes, typically in 20-foot or 40-foot versions, to accommodate various storage needs. They can also be used as shipping container freezers or portable cold storage units.
- Refrigerated Storage for Multiple Uses: Container cold rooms can be used as temporary refrigerated storage for events, construction sites, or during peak demand periods.
Reefer containers are often used by logistics companies, food suppliers, and medical institutions to ensure the safe transport and storage of temperature-sensitive goods.
Key Differences Between Cold Room and Container Cold Room
- Mobility:
- Cold Room: Cold rooms are stationary installations and cannot be relocated once built. They are integrated into the facility’s infrastructure.
- Container Cold Room: A reefer container is a portable solution that can be moved between different locations, making it ideal for businesses that require flexibility in their cold storage needs.
- Usage:
- Cold Room: Cold rooms are perfect for long-term storage and consistent use in a fixed location. They are typically utilized for larger, permanent operations such as food processing plants, restaurants, and pharmaceutical facilities.
- Container Cold Room: Reefer containers are used for both transportation and temporary storage, such as refrigerated shipping containers for exporting goods or a cold room container for event catering and seasonal demands.
- Cost:
- Cold Room: Installing a cold room can be costly due to the construction, refrigeration system, and labor involved. However, it is an investment for businesses requiring permanent and large-scale storage.
- Container Cold Room: While reefer containers may be more affordable initially, especially for temporary uses, they may incur transportation costs if frequently moved from one location to another.
- Capacity:
- Cold Room: Cold rooms are custom-built, so they can be designed to store significantly larger quantities of products compared to container cold rooms.
- Container Cold Room: The capacity of reefer containers is limited to their size, typically 20-foot or 40-foot containers. These are ideal for businesses with moderate cold storage requirements or for temporary expansion.
- Cold Room Installation and Maintenance:
- Cold Room: Installation involves setting up the entire infrastructure, including the refrigeration system, insulation, and airflow management. Maintenance is also more complex due to the built-in nature of the cold room refrigeration system.
- Container Cold Room: Reefer containers are much easier to deploy and maintain. They can be placed and connected to a power source with minimal installation. Maintenance is often more straightforward since the refrigeration unit is contained within the shipping container freezer.
Choosing the Right Option for Your Business
The decision between a cold room and a container cold room depends on several factors, including the nature of your business, budget, and storage requirements.
- Cold Room: Choose a cold room if your business requires permanent, large-scale storage with consistent use, such as in warehouses or large restaurants.
- Container Cold Room (Reefer Container): Opt for a reefer container if you need portable and flexible storage that can accommodate seasonal needs, event-based services, or transportation of perishable goods.
Both options provide reliable cold storage, but your choice should align with your operational needs, whether it’s a walk-in refrigerator for a busy restaurant or a portable cold storage container for an event.
FAQ
Q: What is the main advantage of a reefer container?
A: The primary advantage of a reefer container is its portability. It allows businesses to transport temperature-sensitive goods over long distances or provide temporary cold storage in various locations.
Q: Are cold rooms more energy efficient than container cold rooms?
A: Cold rooms are generally more energy-efficient when used for permanent storage due to their insulated walls and dedicated refrigeration systems. Reefer containers, while effective for temporary use, may consume more energy, especially when frequently relocated.
Q: Can a container cold room be used as a permanent storage solution?
A: Yes, while container cold rooms are designed for temporary or mobile use, they can also serve as a long-term storage solution in situations where flexibility is required.
Q: How long can a refrigerated container maintain its temperature during transit?
A: Reefer containers are designed to maintain a consistent temperature for extended periods during transit, typically ranging from a few days to several weeks, depending on the quality of the refrigeration system and the insulation.
Q: What sizes are available for reefer containers?
A: Reefer containers typically come in 20-foot and 40-foot sizes, providing flexibility in storage capacity for various types of goods.
