So called ISO Container are standardized high capacity containers (freight containers) made out of steel that allow for an easy and fast loading, handling, storing and discharging of goods. You mainly find 20foot Container – the so called TEU (Twenty foot equivalent unit)– and 40-Foot-Container (FEU = forty foot equivalent unit).

Container mainly consists of steel (usually the robust Cor-ten steel). The walls of the containers are made out of sheet metal plates. (Corrugation) The container has a protective coat of lacquer and gets its own container serial number. You can differ those standard containers (Dry containers) that we use for our business as follows:

Model	External dimensions			Internal dimensions			Door opening		Weight
	Length	Width	Height	Length	Width	Height	Width	Height	Gross	Net
20’ Standard DC (Dry Container)	6,058	2,438	2,591	5,895	2,350	2,392	2,340	2,292	24.000kg	1.900kg
20’ Standard HC (High Cube DC)	6,058	2,438	2,896	5,895	2,350	2,697	2,340	2,585	24.000kg	2,000kg
40’ Standard DC (Dry Container)	12,192	2,438	2,591	12,029	2,350	2,392	2,340	2,292	30.480kg	3.800kg
40’ Standard HC (High Cube DC)	12,192	2,438	2,896	12,029	2,350	2,697	2,340	2,585	30.480kg	4.000kg
40’ HC (High Cube) Reefer Container	12,192	2,438	2,896	11,583	2,286	2,532	2,294	2,550	34.000kg	4,150kg

Reefer containers are being divided into 2 categories, but with all our projects we only use containers with integrated cooling system- (Integral container, Integral-Reefer). Integral containers do have their own cooling unit which is integrated in the wall opposite the front wall and runs by electrical power. Every container can be set separetely to a certain cooling or heating temperature. This will be supervised and recorded constantly by the built in electronics. To compensate the additional weight of the cooling system, the walls of integral reefers are often made out of aluminium. Because of the insulation, Reefer containers are also slightly different in internal width, length and height compared to those of a normal ISO container.
