Refrigerated containers, commonly known as reefers, are temperature controlled shipping containers allowing cargo to travel across the world.
Refrigerated shipping containers are the ideal way to transport goods that need to be kept cold; Reefer containers come in 20ft & 40ft lengths. However, there is slightly less cargo space available inside the reefer container due to space is taken up by the refrigeration unit and ventilation equipment.
