What is a refrigerated container?

Refrigerated containers also known as reefers container are containers used in intermodal freight transport. That is to say that they’re used for shipping temperature-sensitive goods that require refrigeration. These containers have a built-in refrigeration unit. Refrigerated containers can keep their internal temperatures stable. They have adequate airflow and humidity control. These features will aid in the preservation of perishable goods by protecting them from spoilage caused by heat, extreme cold, a lack of adequate airflow, or excessive humidity.

These units can be charged with diesel-powered generators during transport to keep the container’s temperature consistent. ISO containers can reach and maintain temperatures of -65 to 40 degrees Celsius

Composition of a refrigerated container

A controller unit at the front of a reefer container adjusts the temperature, ventilation, and humidity settings for specific cargo types. A refrigerated container is outfitted with a power plug cable that can be connected to a vessel, a terminal, or the truck's genset. These typically maintain a temperature range of -20 to 30 degrees Celsius, making them suitable for temperature-controlled commodities shipping.

The air exchange system in reefer units helps maintain optimal oxygen levels, keeping products fresh, while the dehumidification feature keeps the environment inside the container dry.

The body of the refrigerated container

Reefer containers are usually made from a quality, solid stainless steel frame to help withstand many goods. 

  • The outer layer is made or stainless steel.
  • The middle layer is PU with good insulation.
  • The innermost layer is corrugated stainless steel to increase the container's rigidity.

Refrigeration system

The refrigeration system includes an air conditioner, evaporator, condenser, and compressor.

  • Air conditioners usually belong to famous brands such as Daikin, Thermoking, and Mitsubishi.
  • Evaporator: is the primary heat exchanger part of the refrigerated container, which absorbs heat from the cold environment, then boils and evaporates.
  • Condenser: Cooled by circulating air.
  • Compressor: This is considered the heart of the refrigerated container, playing the role of compressing the refrigerant from low pressure to a higher pressure.

The structure of the reefer container also includes an automatic power-off system and cooling from the blower.

How a refrigerated container works

Two fans circulate the air inside refrigerated containers. Firstly, The air is pushed downward and enters the container space via the T-bar floor. Refrigerated containers have aluminum T-bar floors that are specifically designed to allow for air circulation, which is necessary for cargo temperature maintenance. Then, The air circulates through the cargo, maintaining a constant temperature. The air is then pushed through the cooling engine again by propellers, and the process is repeated. This constant air movement keeps products fresh.

  • What exactly is a non-operational reefer container?

--> Non-operational reefers are shipping containers that have their refrigeration units turned off. These can be used to store goods, usually stored in a dry container. Due to a lack of demand, shipping companies use these as dry boxes rather than leaving them idle or returning them to their origin as empty containers.

  • What are gensets for refrigerated containers?

--> Gensets or generator sets are essential for a reefer container. These are used when a regular shore power supply is unavailable for reefers. A reefer container needs a constant supply of power and gensets to ensure that there are no interruptions in cooling and your goods are not spoiled.
