Desiccant Dryer — Heated

A heated desiccant dryer delivers extremely dry compressed air with a pressure dew point of -40°C — significantly drier than the heatless variant. The built-in heating makes the regeneration process more efficient, meaning only 4–6% of the compressed air needs to be used as purge air, compared to 12–15% for the heatless variant.

The system uses activated alumina or molecular sieves as adsorbent and operates in cycles of 60–180 minutes. The lower purge air consumption means more of the produced compressed air is available for production, resulting in lower total operating costs at high capacity requirements. Inlet oil content below 0.01 ppm ensures long desiccant life.

With capacities from 1.2 to 130 m³/min, the heated desiccant dryer is the right choice for demanding applications such as cold storage, freezer storage, pharmaceutical production, and electronics manufacturing — everywhere a -40°C pressure dew point is needed and operating economy matters.
