ADC Series Desiccant Wheel Dryer

Sterling brings a century of experience to provide premium value and quality. The ADC Series Desiccant Bed Dryer leverages the Sterling legacy and expertise to provide a system that is suited for most drying applications including extrusion, injection molding, and blow molding.

The ADC Series Dryer combines the efficiency of a wheel dryer with an integrated pneumatic conveying system, a receiver for the drying hopper, a receiver for the IMM and all related accessories. The ADC Series is particularly suitable as an independent flexible dryer to be positioned next to the processing machine.

How The Wheel Dryer Works

  • The wheel is rotating driven by a step motor through 3 main sections: drying, regeneration and cooling.

    • In the first section the humid process air coming from the material hopper through a return air filter is dried in two stages and the dry air is returned by the process blower through a heating chamber to the material in the drying hopper
    • Parallel to that a part of the turning wheel is in regeneration with its own dedicated heat chamber and regeneration blower
    • In the cooling section a part of the wheel is cooled down before it re-turns back into the drying process
