FAQ

What is a desiccant wheel dryer?

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

Do I need a dehumidifying dryer to create filament?

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.

Can I use it with GP20?

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.
