Reefer Sizes & Types: Complete Guide 

When it comes to temperature-sensitive storage, choosing the right reefer container is essential. Whether you’re storing perishable food, pharmaceuticals, floral arrangements, or specialty materials, the right reefer size and setup can make a significant difference in maintaining product integrity, ensuring compliance, and optimizing energy efficiency. 

At Container Technology, we offer a range of reefer container sizes and configurations tailored to meet your specific storage and transportation requirements. In this guide, we’ll cover the most common reefer sizes, their key features, and how to determine which one best suits your business operations. 

What is a Reefer Container?

A reefer container is a temperature-controlled shipping container designed to maintain specific internal conditions regardless of the surrounding environment. Equipped with an integrated cooling and heating system, reefers can typically sustain temperatures from -20°F to 85°F, depending on the model and configuration. 

These containers are built with durable steel or aluminum exteriors and high-grade insulation, ensuring consistent internal temperatures. Their aluminum T-rail flooring promotes even airflow and allows for smooth movement of goods using pallet jacks or forklifts. Most models are powered by 230V or 460V 3-phase electrical systems, providing dependable, energy-efficient performance. 

Because of their precision and reliability, businesses across industries commonly use reefers for applications such as food and beverage, pharmaceuticals, floristry, and manufacturing. They provide reliable solutions anywhere product quality relies on consistent temperature control. 

Common Reefer Sizes

Reefer containers are available in several standard sizes, each designed to accommodate different capacities and operational requirements. Choosing the correct size ensures you get the most value out of your investment without overspending on unused space. 

20ft Reefer Containers

Best for: Mid-size distributors, grocers, and food processors 

The 20ft refrigerated container is one of the most popular sizes in commercial and industrial settings. It offers a perfect balance between capacity and site efficiency, providing ample space for palletized goods while remaining relatively easy to position or relocate. 

Specifications: 

• External Dimensions: 20’ L x 8’ W x 8.6’ H 
• Internal Volume: 1,010 cubic feet 
• Power: 230V 3-phase or 460V 3-phase 
• Temperature Range: -20°F to 85°F 

Typical Applications: 

• Long-term storage of frozen or chilled foods, including meat, seafood, and dairy 
• On-site refrigeration for food processing plants or distribution centers 
• Temporary cold storage for grocery stores during remodels or expansions 
• Pharmaceutical or biomedical storage that requires precise temperature control 

The 20ft reefer is also a great option for seasonal businesses or those with fluctuating storage demands. It can be delivered pre-cooled and placed virtually anywhere, allowing for quick deployment without expensive construction. 

40ft Reefer Containers

Best for: Large-scale storage, logistics, and industrial users 

For business operations that handle large volumes of temperature-sensitive goods, the 40-foot reefer is the ideal choice. Its large size makes it ideal for bulk storage or palletized inventory. 

Specifications: 

• External Dimensions: 40’ L x 8’ W x 9.6’ H 
• Internal Volume: 2,380 cubic feet 
• Power: 230V 3-phase or 460V 3-phase 
• Temperature Range: -20°F to 85°F 

Typical Applications: 

• Warehousing for grocery chains, distributors, and e-commerce fulfillment 
• Cold chain logistics for large-scale shipments 
• Export or import of frozen and chilled goods 
• Storage of high-value perishables for food manufacturers or distributors 

Reinforced floors make these containers suitable for forklifts and pallet jacks, and their heavy-duty design ensures durability even in demanding industrial environments. For companies that require both capacity and reliability, the 40ft reefer provides unmatched value. 

In addition to these standard reefers, Container Technology also offers 40-foot refrigerated trailers and 20-foot walk-in coolers/freezers to fit your business’ unique needs. 

Factors to Consider When Choosing a Reefer Container

Selecting the right reefer container size is about more than the amount of space you need. Several key factors determine which container will perform best for your business: 

1. Storage Capacity 

Evaluate how much product you’ll be storing and how frequently you’ll access it. For smaller operations or backup storage, a 20ft container may be sufficient. For high-volume distribution or warehousing, a 40ft model will likely offer a more practical solution. 

2. Temperature Requirements 

Different products require different temperature ranges. For instance, frozen goods may need sub-zero temperatures, while produce or pharmaceuticals may require mid-range or ambient cooling. Always confirm your product’s specific storage guidelines before selecting a unit.

3. Power Availability 

Most reefers operate on 230V or 460V 3-phase power. Ensure your facility or job site has the appropriate electrical setup before installation. 

4. Site Space & Accessibility 

As you prepare for a storage unit, verify that your site has enough room for delivery and installation, as well as for personnel to safely load and unload goods. 40-foot refrigerated containers, for example, require more clearance due to their large size, so be mindful of where you will keep the unit.

5. Duration of Use 

Consider whether you need the container short-term or long-term. Purchasing often offers better long-term savings for ongoing operations and offers reliable, on-site refrigerated storage for all business operations.
