ADW Compact Series
ADW Compact Series Desiccant Wheel Dryer
Sterling brings a century of experience to provide premium value and quality. The ADW 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.
Sterling’s ADW14 and ADW25 desiccant wheel dryers are engineered for low-throughput applications requiring compact, energy-efficient drying solutions. Designed with a minimal footprint, these models are among the smallest desiccant wheel dryers available today—ideal for small injection molding or extrusion processes, including those in medical manufacturing.

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
