20ft Reefer Container Dimensions
A 20ft reefer container provides refrigerated storage in a compact container size, making it useful for businesses that need dependable cold storage but do not have room for a larger 40ft unit. The refrigeration system takes up part of the container’s interior space, so the internal dimensions are slightly smaller than a standard dry storage container.
| Dimension | Measurement |
|---|---|
| External Length | 20 ft / 6.09 m |
| External Width | 8 ft / 2.44 m |
| External Height | 8 ft 6 in / 2.62 m |
| Internal Length | 19 ft / 5.8 m |
| Internal Width | 7 ft 8 in / 2.34 m |
| Internal Height | 7 ft 10 in / 2.38 m |
| Door Width | 7 ft 8 in / 2.34 m |
| Door Height | 7 ft 5 in / 2.26 m |

20ft Reefer Container Weight and Capacity
Weight capacity is important when planning refrigerated storage, transport, loading, and delivery. A 20ft reefer container is heavier than a standard dry container because it includes insulation and a built-in refrigeration unit.
- Tare weight: approximately 6,370 lbs / 2,890 kg
- Maximum payload: approximately 60,830 lbs / 27,590 kg
- Gross weight: up to 67,200 lbs / 30,480 kg
Actual usable capacity depends on the container type, refrigeration unit, cargo weight, airflow requirements, shelving, and how the products are loaded. For refrigerated goods, it is important to leave enough space for airflow so the container can maintain a consistent temperature throughout the interior.
20ft Reefer Temperature Range
Temperature range depends on the refrigeration unit installed in the container. Conexwest lists multiple 20ft reefer unit options, including Carrier, Daikin, and Thermo King units.
- Carrier units: -20°F to +70°F
- Daikin units: -20°F to +70°F
- Thermo King units: -40°F to +70°F
These temperature ranges make 20ft reefer containers suitable for many perishable products, including produce, dairy, meat, seafood, beverages, flowers, and certain pharmaceutical products. If your goods require deep-freezing or rapid freezing, a blast freezer container may be a better fit than a standard refrigerated container.

Types of 20ft Reefer Containers
Not every 20ft refrigerated container is built for the same application. The best option depends on your required temperature range, power availability, product type, and storage timeline.
20ft Standard Refrigerated Container
A standard 20ft refrigerated container is designed for general cold storage and refrigerated transport. It is commonly used for food, beverages, produce, dairy products, floral inventory, and other temperature-sensitive goods.
Conexwest offers 20ft refrigerated containers with refrigeration units from major manufacturers, including Carrier, Daikin, and Thermo King.
20ft Single-Phase Refrigerated Container
A 20ft single-phase refrigerated container is useful for locations where three-phase power is not available. Conexwest’s single-phase 20ft reefer option works on 220V, 1-phase, 30 or 50 amp power and is designed for applications that need cold storage in locations with more limited electrical access.
This option is especially useful for smaller businesses, event sites, temporary storage areas, and facilities without industrial power infrastructure.
20ft Blast Freezer Container
A 20ft blast freezer container is designed for products that need colder temperatures or faster freezing. These units are often used for seafood, meat, frozen food, and other goods that require more aggressive temperature control.
For freezer-specific applications, see Conexwest’s cold storage and freezer container options.
20ft Dual-Temperature Reefer Container
A 20ft dual-temperature reefer container includes a movable partition wall that allows the container to support two separate temperature zones. This can be useful for businesses that need to store chilled and frozen products in the same container.
20ft High Cube Reefer Container
A 20ft high cube reefer container provides additional height compared with a standard unit. This can be helpful when storing taller pallets, racking systems, or bulkier temperature-sensitive products.
Common Uses for 20ft Reefer Containers
Because a 20ft reefer container combines cold storage with a compact footprint, it works well for both temporary and long-term applications. Businesses use 20ft refrigerated containers when they need reliable temperature control without committing to a full warehouse cold room or larger container.
Food and Beverage Storage
Restaurants, caterers, grocery stores, food distributors, and event operators use 20ft reefers to store perishable goods such as produce, dairy, meat, seafood, frozen foods, and beverages.
Pharmaceutical and Medical Storage
Many medical and pharmaceutical products require controlled temperatures to remain stable. A 20ft reefer can provide temporary or supplemental cold storage for healthcare supplies, medical inventory, and temperature-sensitive products.
Event Catering and Temporary Cold Storage
For festivals, outdoor events, weddings, food service operations, and emergency refrigeration needs, a 20ft refrigerated container can provide flexible on-site cold storage.
Agriculture and Floral Storage
Farmers, growers, florists, and agricultural businesses use refrigerated containers to store harvested products, flowers, nursery inventory, and temperature-sensitive materials before distribution.
20ft Reefer vs 40ft Reefer: Which Size Do You Need?
A 20ft reefer container is usually the better choice when you need compact cold storage, easier placement, lower rental cost, or a unit that fits in a tighter site. A 40ft reefer container may be better if you need more storage capacity, larger pallet volume, or long-term bulk refrigerated storage.
If you are comparing refrigerated container sizes, consider the following:
- How much product needs to be stored?
- How much site space is available?
- Do you have the proper electrical power?
- Will the container be used short-term or long-term?
- Do you need chilled, frozen, or dual-temperature storage?
- Will products require shelving, pallet access, or airflow spacing?

Should You Rent or Buy a 20ft Reefer Container?
Renting a 20ft reefer container is often the better choice for short-term projects, seasonal demand, events, emergency cold storage, renovations, and temporary overflow inventory. Buying may make more sense for businesses with year-round cold storage needs or long-term operational use.
