Abstract: The system comprises sensors (30, 31) for detecting the content of oxygen (O 2) and the carbon dioxide (CO 2) in the container atmosphere and a controller (27) assigned to the container for O 2and CO 2values detected by the sensors, where the values are compared with the predetermined value. In the case of deviation of the first value, the controller produces control signals on an actuation media (32) for increasing or decreasing the O 2and/or the CO 2-value in the container atmosphere, in order to alter the O 2and/or CO 2-value in the direction of an approach. The system comprises sensors (30, 31) for detecting the content of oxygen (O 2) and the carbon dioxide (CO 2) in the container atmosphere and a controller (27) assigned to the container for O 2and CO 2values detected by the sensors, where the values are compared with the predetermined value. In the case of deviation of the first value, the controller produces control signals on an actuation media (32) for increasing or decreasing the O 2and/or the CO 2-value in the container atmosphere, in order to alter the O 2and/or CO 2-value in the direction of an approach. The container is connectable to a nitrogen supply device spatially separated by the container, which is resent in a position such that several homogenous containers are supplied with a nitrogen stream. Actuation means (37) for controlling the nitrogen stream are adjusted during connection of nitrogen supply installation by the controller with respect to the CO 2content in the container. The container comprises a sensor for detecting the humidity content and/or the temperature in the container. The nitrogen production device comprises a controller for adjusting the nitrogen content and/or the flow rate of the nitrogen stream leaving the nitrogen production device. A moistening device (38) is intended, over which a gas flow of increased humidity is transferred into the container. The moistening device is assigned to the nitrogen production device and by which an increased moistness is provided in the gas flow leaving the nitrogen production device and in the gas flow supplied into the respective container. The controller of the container is coupled with the control of the nitrogen production device and/or the moistening device. The actuation media is formed for increasing or decreasing the O 2and/or the CO 2-value by a controllable opening of the container wall. The nitrogen production device comprises a nitrogen membrane, through which the external air supplied over a compressor is flowed for the increase of the nitrogen-content in air. The gas flow with increased nitrogen-content is transferred via distributor channels to the containers. The nitrogen production device is inserted in a standard container. The moistening device collects condensate from a cooling-, an adsorption- or membrane dryer plant and controllably transfers into the containers. The controller of the container comprises a storage device for the logging of operating parameters of the respective container. The container comprises an identification mark, which is stored together with the data set representing the operating parameters of the container. The operating parameters of the containers, the nitrogen production device and/or the moistening device are centrally stored and evaluated.
