A system for controlling the atmosphere in a produce storage room (1), in which a nitrogen source (4) is used for initially purging the room, a carbon adsorption bed (3) is used for adsorbing carbon dioxide in the room atmosphere when circulated through the bed, thereby to control the carbon dioxide content of the atmosphere, after regeneration of the bed to desorb carbon dioxide the bed is purged of oxygen with nitrogen from the source, and this purging step is manipulated to control the oxygen content of the room atmosphere. |
