With the CALOSEC CSA(-V) Premium series, desorption occurs in counter flow to the adsorption direction with heated ambient air, and cooling is achieved using ambient air in co-current flow. This results in zero compressed air loss for regeneration (Zero Purge).
Use of the ‘Zero Purge’ process depends on the ambient dew point. It can only be used up to a maximum value. Unlike conventional Zero Purge dryers, the CALOSEC CSA(-V) series can be reliably used even in phases with higher ambient dew points when AMBIENT CONTROL is activated.
