Adsorbent fill method - snowstorm filling UniquetoCompAirmodulardryersisthesnowstormfillingtechniqueusedtochargethedryingchamberswithadsorbentdesiccantmaterial.Thebenefitsofthesnowstormfillingtechniqueinclude:
Achieves maximum packing density for the desiccant material, fully utilising all of the available space envelope
Prevents channelling of air through the desiccant as seen on traditional twin tower designs. due to channelling, twin tower designs require more desiccant to achieve an identical dewpoint, increasing physical size, operational and maintenance costs
Prevents desiccant attrition which can lead to dusting, blocked filters and loss of dewpoint
Allows 100 % of the available desiccant material to be used for drying, therefore reducing the amount of desiccant required and maintenance costs
100 % of the desiccant is regenerated ensuring consistent dewpoint
Provides a low, equal resistance to air flow allowing multiple drying chambers and multiple dryer banks to be used, a feature only available with Adsorption dryer
ensures continuous dewpoint performance
Inconsistent drying and desiccant attrition
Consistent drying with no desiccant attrition

Adsorption DryersA068XS - A340XS
distribution manifolds and drying columns are all constructed from lightweight, high tensile extruded aluminium
The shape of the extrusion varies on each model range
All extrusions are below 150 mm (6”) in diameter, which is under the pressure vessel inspection requirements of ASMe
World-wide design approvals include Ped, CRn, Ce
