Abstract
An inert gas atmosphere of nitrogen and carbon dioxide is created in a refrigerated container having a diesel engine. A lower oxygen content is maintained by an oxygen limit control while the nitrogen is led into the interior of the container from a gas bottle connected with the container when the predetermined oxygen limit value is exceeded. While the inert gases are being supplied, a constant flow of cold gaseous nitrogen is produced by an electrical evaporator in the liquid nitrogen storage tank and connected to the generator of the diesel engine while carbon dioxide is removed from the gas bottle, heated, released to a constant pressure and fed into the container via throttle points constituting a parallel-switched group of such throttle points which can be individually activated.
