The Low-Purge Heat-of-Compression Regenerative Desiccant Air Dryer utilizes the thermal energy contained in the high-temperature compressed air discharged from the air compressor to directly heat the desiccant after the adsorption cycle. The heat desorbs the accumulated moisture from the desiccant, allowing it to be thoroughly regenerated. No compressed air is consumed during the heating and regeneration stage, while only a small amount of dry product air is required during the cooling stage. This significantly reduces compressed-air losses and improves overall energy efficiency.
To ensure stable drying performance and reliable long-term operation, the HOC-E Efficient Adsorption Dryer should be used under the following recommended conditions:
- Applicable fluids: Compressed air, non-corrosive air
- Rated inlet pressure: 0.7 MPa
- Optional pressure range: 0.6–1.0 MPa, customizable
- Rated inlet temperature: 120°C
- Allowable inlet temperature range: 110–180°C
- Regeneration gas consumption: ≤ 3%
- Outlet pressure dew point: -20°C / -40°C optional
- Cooling water temperature: ≤ 32°C
- Cooling water pressure: 0.2–0.6 MPa
For the best operating result, the dryer should be installed in a properly designed compressed air system with stable inlet conditions and suitable cooling capacity. Both air-cooled and water-cooled configurations are available to match different industrial environments and project requirements.
