The DA dryers use the principle of adsorption under pressure in order to effectively dry the compressed air produced upstream of the network. Thanks to its efficient system of two columns without heat integrated on a functional chassis, this allows the achievement of the dew point under expected pressure (-40°C to -70°C). In this sense, each column contains a volume of desiccant defined to ensure adsorption of the water contained in the air. During regeneration, the desiccant releases the water molecules captured under the effect of the stream of compressed air.
The adsorbent is then ready for a new drying cycle.
