Key Takeaways

Reefer containers are commonly used to safely transport fresh products.
Various kinds of reefer containers are available, such as controlled atmosphere and dual temperature reefers.
These containers play a key role in the agriculture, pharmaceuticals, and seafood industries.
To choose the right container, consider temperature ranges, container size, energy use, and cost.
At Conexwest, we provide high-quality and sturdy reefer containers at a competitive price and with high-quality customer service.

7 Types Of Reefer Containers

1. Closed Reefer Containers

These are currently the most widely used reefers in the maritime sector. Closed reefers have an integral front wall and an automatic cooling and heating unit that’s fully electric.

They are capable of sustaining temperatures ranging from -25°C to 25°C - ideal for fruit, vegetables, dairy, and meat.

2. Modified/Controlled Atmosphere (MA/CA) Containers

If you’re moving highly sensitive goods like fresh fruits and vegetables, this is another good option.

MA/CA containers have sophisticated insulation and air flow systems for the regulation of oxygen, carbon dioxide, and ethylene. This environment slows down product decay and extends shelf life significantly.

3. Deep-Freeze Refrigerated Containers

Deep-freeze refrigerated containers are for transporting goods that need to be kept at super low temperatures (typically -35°C to -25°C). These types of units are suitable for frozen foods like ice cream, frozen meat, and fish.

4. Automatic Fresh Air Management (AFAM) Containers

AFAM containers are all about precision. They automatically regulate fresh air supply to create ideal conditions for cargo that require a defined humidity and temperature range.

5. Dual and Triple-Temperature Reefer Containers

Dual and triple-temperature reefer containers contain multiple compartments, which can operate at different temperature zones in a single setup. As such, you can carry frozen seafood in one compartment and chilled fruits in another.

6. Offshore Reefer Containers

Constructed to be highly rugged for use in marine applications, offshore reefers are widely used in the fishing industry. They are engineered to cope with the rigors of deep sea open ocean environments and store seafood and other perishable items.

7. Refrigerated or Cool Tank Containers

These special containers are designed specifically to carry temperature-sensitive liquids, such as drugs or milk. With circulating brine or synthetic oil, they continuously control temperature to maintain the top quality of their liquid cargo.

Conexwest, a leader in shipping and storage solutions based in Northern California, offers new, used, and refurbished containers from 10ft to 45ft, with fast delivery within 3–7 days and container fabrication options like adding shelves and locks.

Food Industry: The transport of fresh produce, meat and seafood, dairy products, and frozen foods for keeping freshness and safety.
Pharmaceutical Industry: For the safe delivery of temperature-dependent drugs and vaccines.
Chemical and Biotech Industries: The transportation of specialty chemicals and biotechnological substances sensitive to temperature that must be maintained at a precise level to prevent decomposition.
Agricultural Exports: Shipping fresh fruits, vegetables, and flowers to international markets.
Beverage Industry: Maintaining the quality of alcoholic beverages, juices, and soft drinks during transport.
Catering and Events: Temporary refrigeration solutions for large quantities of perishable food during events and gatherings.
Art and Cultural Heritage: Safeguarding of art and cultural material objects in need of controlled conditions during handling.
Electronics Industry: Protecting sensitive electronic components from temperature fluctuations during shipping.
Cosmetics and Skincare: Transporting beauty products that need temperature control to maintain their effectiveness.

6 Factors To Consider When Choosing A Reefer Container

1. Understand Your Cargo Requirements

Identify the temperature needs of your cargo. Different products have varying requirements, such as:

Frozen Goods: Require temperatures around -20°C to -30°C.
Chilled Goods: Typically need a range between 0°C and 10°C.
Sensitive Cargo: Items such as chemicals are likely to need accurate control of humidity and/or atmospheric conditions.

2. Select the Right Size

Reefer containers commonly come in 20ft and 40ft sizes. The decision depends on the amount of goods that you need to be moved.

3. Evaluate Cooling Technology

Select a container with an effective cooling system capable of keeping regulated temperatures. Look for features like:

Energy Efficiency: To minimize operational costs.
Real-time Monitoring: Built-in sensors for temperature and humidity monitoring.
Alarm Systems: Alerts for any temperature deviations or system malfunctions.

4. Check Durability and Insulation

Material Quality: Verify that the container is manufactured from corrosion-resistant materials that are able to tolerate extreme conditions.
Insulation Thickness: Thick insulation can help maintain the temperature, especially in extreme conditions.

5. Consider Power Supply Options

Reefer containers require a reliable power source to operate:

Plug-in Power: Standard electrical connections for refrigeration.
Backup Power Solutions: Diesel generators for emergencies, long-haul, or off-grid shipments.

6. Look for After-Sales Support and Maintenance

Supplier Reliability: Select a reliable supplier (like us!) who provides excellent after-sales care including maintenance and spare parts availability.
