How to Operate a Reefer Container

What is a reefer container and how does it work?

A reefer container, short for refrigerated container, is a specialized shipping container designed to transport temperature-sensitive cargo. These containers play a crucial role in the global supply chain, enabling the safe transportation of perishable goods across long distances while maintaining optimal temperature conditions.

Reefer containers function as mobile refrigeration units, combining the structural integrity of standard shipping containers with advanced cooling systems. The primary components of a reefer container include:

Insulated walls: The container’s walls, floor, and ceiling are constructed with thick insulation materials to minimize heat transfer between the interior and exterior environments.

Refrigeration unit: This is the heart of the reefer container, typically located at one end. It consists of a compressor, condenser, evaporator, and expansion valve, working together to maintain the desired internal temperature.

Temperature control system: A sophisticated control panel allows operators to set and monitor the internal temperature, ensuring precise climate control throughout the journey.

Air circulation system: Fans and air ducts distribute cold air evenly throughout the container, preventing hot spots and ensuring uniform cooling of the cargo.

Power supply: Reefer containers can be powered by external electrical sources when stationary or by generator sets (gen-sets) during transit.

The cooling process in a reefer container follows the basic principles of refrigeration:

The compressor pressurizes and heats the refrigerant gas.
The hot, high-pressure gas flows through the condenser, where it releases heat and condenses into a liquid.
The liquid refrigerant passes through an expansion valve, which reduces its pressure and temperature.
The cold, low-pressure refrigerant enters the evaporator, absorbing heat from the container’s interior and vaporizing.
The cycle repeats, continuously removing heat from the container and maintaining the desired temperature.

Reefer containers can typically maintain temperatures ranging from -30°C to +30°C (-22°F to +86°F), accommodating various cargo requirements. This wide temperature range allows for the transportation of diverse products, including:

Frozen goods: Ice cream, frozen meats, and seafood
Chilled products: Fresh fruits, vegetables, dairy products, and pharmaceuticals
Temperature-sensitive items: Electronics, chemicals, and fine art

The versatility of reefer containers has revolutionized global trade, enabling the transportation of perishable goods to markets worldwide while preserving their quality and extending shelf life.

How do you prepare a reefer container for operation?

Proper preparation of a reefer container is crucial for ensuring the safe and efficient transportation of temperature-sensitive cargo. This process involves several key steps that must be carried out meticulously to guarantee optimal performance throughout the journey.

Inspection and cleaning

Begin by thoroughly inspecting the container’s interior and exterior. Look for any signs of damage, such as dents, holes, or cracks that could compromise the container’s insulation or structural integrity. Pay special attention to the door seals, ensuring they are intact and capable of maintaining an airtight seal.

Clean the container’s interior using appropriate cleaning agents and disinfectants. This step is particularly important when transporting food products or pharmaceuticals to prevent contamination and maintain hygiene standards.

Refrigeration system check

Examine the refrigeration unit for any visible damage or signs of wear. Verify that all components, including the compressor, condenser, and evaporator, are in good working condition. Check refrigerant levels and top up if necessary, following manufacturer guidelines and environmental regulations.

Test the temperature control system by running the unit through its full range of temperatures. This process helps identify any potential issues with temperature regulation before loading cargo.

Power supply verification

Ensure that the container’s power connections are compatible with the available power sources at both the origin and destination. This includes checking voltage requirements and plug configurations. If using a generator set (gen-set), verify its fuel levels and overall condition.

Pre-trip inspection (PTI)

Conduct a comprehensive pre-trip inspection, which typically includes:

Thermostat calibration: Verify that the thermostat accurately reflects the internal temperature.

Temperature recorder test: Ensure that the temperature recording device is functioning correctly and properly calibrated.

Defrost cycle check: Test the defrost system to confirm it operates as intended, preventing ice buildup on the evaporator coils.

Air leakage test: Perform a pressure test to detect any air leaks that could affect temperature stability.

Pre-cooling

Pre-cool the container to the required temperature before loading cargo. This process can take several hours, depending on the target temperature and ambient conditions. Pre-cooling helps minimize temperature fluctuations during loading and reduces strain on the refrigeration system.

Documentation and record-keeping

Prepare and organize all necessary documentation, including:

Maintenance records: Document any recent repairs or maintenance activities.

Temperature logs: Set up temperature recording devices and ensure they are properly configured.
