Temperature Controlled
Refrigerated units are also thermally insulated, meaning that there is a delayed temperature adaptation to the outside climate once the control mechanism is deactivated. This ensures that your cargo will remain in a healthy condition between plugins, and for the entire duration of transit.
- Consistent cargo temperature throughout plugged-in transit.
- Slow gain or loss of temperature between plugins.
- Extended shelf life of perishables.

Temperature Controlled Liner Agency Services - FAQs
What temperatures can a reefer container be set to?
Reefer containers can be set at any temperature from -30oC to 30oC, providing a stable transit climate for a plethora of commodities. This flexibility of temperature control, within the same unit, also allows liner agents to effectively manage reefer equipment around the world.
Whilst plugged in or connected to a genset, reefer containers will remain at their set temperature. When unplugged, reefer containers will gradually acclimatise to the surrounding temperature over the course of several days or weeks, depending on the temperature gradient.

What are the different types of refrigerated containers?
There are 3 standard types of reefer container: closed, modified / controlled atmosphere (MA/CA), and automatic fresh air management (AFAM). It is important to utilise the correct type of temperature-controlled unit for the commodity that is being transported.
Closed reefer containers are sealed units with electric cooling / heating capabilities. These do not have ventilation or air exchange systems.
Modified / controlled atmosphere (MC/CA) units have the capability to replace lost oxygen in the container through a gas exchange system.
Automatic fresh air management (AFAM) temperature-controlled units regulate oxygen, carbon dioxide, and other gases.

How long does it take for an unplugged reefer to return to ambient temperature?
Reefer temperatures can be set between -30oC to 30oC, allowing a stable climate whilst plugged in. When a reefer container is unplugged, and not attached to a genset, it begins to acclimatise to the external temperature.
The rate of temperature change is dependant on the difference in temperature between the inside of the container and the external ambient temperature. Chilled units gain approximately 1oC a day in milder countries, but in hotter countries this can be 2-3oC, or more.

How do you pack a reefer container?
Reefer containers need to be correctly packed in order to maintain temperature control and air circulation throughout the entire consignment. If the cargo is not packed well then there is the risk that the condition of the goods will be compromised in transit.
Improperly packed reefers can result in condensation building up on the packaging through close contact with the walls or roof. Once the reefer returns to the freeze cycle, this water will then freeze and reduce the temperature of the affected cargo below the correct setting. Deep freeze can spoil some perishables.
Cory Brothers provide reefer liner services worldwide and can assist with finding general information on how to pack a reefer container. Please get in touch for more information.
Why is there ventilation in some reefer containers?
Some reefer containers require more environmental factors than temperature to be controlled. Cargos such as plants and fruit also require control of the oxygen in the atmosphere during transit. This is achieved through ventilation and gas exchange systems within the reefer unit.
If there is no ventilation for these cargoes, and they are transported in a closed reefer unit, then the cargo can spoil during transit. Plant cargoes require oxygen to be regulated in order to prolong life, whereas the conditions of bananas can cause them to ripen early and reduce shelf life.
