Built for Material Preparation and Workflow Control
The DW14 is a desiccant drying solution used to remove moisture from thermoplastics before extrusion and validation.
It supports material preparation across lab, R&D, and pilot environments, helping ensure stable input conditions for downstream processing.
Material Drying Requirements
Supports melt stability and final part quality
Helps reduce bubbles and weak layers
Critical for engineering and recycled materials
Supports repeatable processing outcomes
Role in the Material Workflow
Moisture control is part of a broader material workflow, supporting reliable processing from preparation to extrusion.
Drying helps materials enter extrusion under stable conditions, reducing variability and supporting repeatable outcomes.
Stabilizes material input before extrusion
Handles materials with varying moisture sensitivity
Helps reduce batch-to-batch variability
Improves repeatability in processing outcomes
In setups where material drying is required, systems like the DW14 can be integrated into the workflow.

FAQ
A desiccant wheel dryer is an advanced drying system that uses a rotating honeycomb desiccant wheel to continuously remove moisture from process air.
Compared to traditional twin-tower systems, this approach delivers:
- more stable drying conditions
- lower energy consumption
- reduced maintenance requirements
Yes, drying thermoplastic materials before extrusion is essential for achieving consistent and reliable results.
Moisture in the material can lead to:
- bubbles and surface defects
- material degradation
- unstable extrusion and diameter inconsistencies
Proper drying ensures materials are conditioned before processing, supporting consistent output and material performance.
Yes, the DW14 can be used to dry plastic granulate produced by the GP20 Shredder. The GP20 produces granules smaller than 4 mm, making them suitable for efficient and consistent drying within the DW14.
