The Blower & Zero Purge Adsorption Dryer is designed to deliver continuous, energy-efficient moisture removal for industrial compressed air systems. Unlike conventional adsorption dryers that consume compressed air during regeneration, this system uses blower-assisted heated regeneration with zero purge, which means no compressed air is used in the regeneration process.
During operation, ambient air is drawn in by a blower and heated before passing through the saturated adsorption tower to desorb moisture from the adsorbent. The regeneration air is then cooled through an intermediate cooler, creating a stable and efficient regeneration cycle. By alternating between adsorption and regeneration, the dryer maintains a continuous supply of dry compressed air with a stable low dew point while significantly reducing operating costs.
This advanced design combines zero compressed air consumption, blower-assisted regeneration, and intermediate cooling, making it an ideal solution for industrial users who require reliable drying performance, long-duty operation, and improved energy efficiency.
To ensure stable performance and efficient operation, the Blower & Zero Purge Adsorption Dryer should be used under the following recommended conditions:
- Applicable fluids: Compressed air, non-corrosive air
- Rated inlet pressure: 0.7 MPa
- Optional inlet pressure range: 0.6–1.0 MPa, customizable
- Rated inlet temperature: 10–30°C
- Maximum inlet temperature: ≤ 40°C
- Inlet air dew point: ≤ 25°C
- Regeneration gas consumption: 0%
- Outlet pressure dew point: -20°C / -40°C optional
- Rated ambient temperature: 35°C
- Usable ambient temperature range: 2–40°C
- Cooling water temperature: ≤ 32°C
- Cooling water pressure: 0.2–0.6 MPa
For the best drying effect and longer adsorbent service life, the dryer should be installed with proper pre-filtration and operated under stable inlet conditions. This helps protect downstream equipment, maintain consistent air quality, and improve long-term system reliability.
