The expression Controlled Atmosphere means that atmospheric air in a certain environment is modified and controlled by differently combined gas mixes, in order to directly or indirectly influence the products or substances contained in such environment.
Carbon Dioxide CO2
Different other gases in infinitesimal percentages
In a Controlled Atmosphere environment this composition is modified in such a way as to create, inside suitable spaces, new gas compositions made up by N2, O2, CO2, which are continuously controlled by means of electronic gas analyzers.
According to the aims required, differentiated plants are designed, to offer different features:
In time the concept of Controlled Atmosphere (CA) underwent a constant evolution and refinement at the same pace as overall industrialization and mechanization progressed, as well as the continuous in-depth University research and changing consumer needs. With respect to the ULO (Ultra Low Oxygen) technique of the former millennium, the DCA (Dynamic Controlled Atmosphere) method shows a clear improvement in quality.
