Two-Circuit Technology
No molecular sieve. No wear. Just physics.
Our proprietary two-circuit system separates the drying process into two independent air circuits — dramatically reducing compressed air consumption while maintaining a constant dew point. Just measurably better drying.
The Drying Hopper
Housing & drying hopper made of high-grade stainless steel with highly efficient insulation. Wet granules enter at the top, dry material exits at the bottom. No blow-in pipes — for optimised temperature distribution and easy cleaning.
Pre-Heating with Ambient Air
Free ambient air is heated — electrically or via waste heat from production machinery. It flows through the upper zone and heats the granules to drying temperature.
Ambient air + waste heat = minimal energy cost for the recirculation circuit
The Result
Every granule uniformly dried. Constant dew point, constant residual moisture. Reproducible over the entire service life — without maintenance, no desiccant.
Drying with Compressed Air
In the lower section, a small amount of compressed air is expanded to atmospheric pressure. The expansion creates extremely dry air with a low dew point — it extracts the deep-seated residual moisture.
Compressed air consumption compared to conventional compressed air dryers.
Automatic Power Regulation
Both circuits automatically adapt to the actual material throughput. Air volumes and heating power are throttled when less material is processed — further energy savings in real-world operation.
