A refrigerated container 2 has associated therewith a compressor 6 which receives filtered air and passes it to a small apparatus 12 for separating air by pressure swing adsorption or by different rates of permeation of gas through semi-permeable membranes. Resulting air depleted in oxygen and water vapor flows into the interior of the container 2 and displaces atmosphere from the container 2 through a vent tube 20. Reducing the oxygen and water vapor content of the atmosphere in the container 2 (which may be a refrigerator or freezer) helps to preserve food stored therein and reduces the deposition of water or ice.
