ADW Series Desiccant Wheel Dryer

Since 1957, AEC has been the leader in drying equipment for the plastics processing industry. The ADW Series Desiccant Wheel Dryer leverages the AEC legacy and expertise to provide a system that is suited for most drying applications including extrusion, injection molding, and blow molding.

Desiccant wheel dryers are the new generation of desiccant dehumidifying dryers. They are far more efficient, more compact, and require less maintenance. Traditional dehumidifying dryers use a large volume of molecular sieves in pellet form composed of at least 30% of clay, which tends to degrade very easily over time. The desiccant wheel instead is completely different where the pure molecular sieve is applied to a synthetic substrate rolled into a cylinder forming a honeycomb structure and covered by a steel protection.

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
