The Low Pressure Differential Refrigerated Air Dryer is designed to provide efficient moisture removal for compressed air systems while maintaining an extremely low pressure drop. It uses a refrigeration drying process to cool hot and moisture-laden compressed air, condense water vapor into liquid, and discharge the condensate before the air reaches downstream equipment.
During operation, compressed air enters the dryer and passes through the internal refrigeration and heat exchange system. As the air temperature decreases, water vapor condenses into liquid water and is separated from the airflow. The treated compressed air is then discharged with a stable pressure dew point of 2°C to 10°C, helping protect pipelines, valves, pneumatic tools, and sensitive production equipment from corrosion, contamination, and moisture-related damage.
Because the system is designed with low pressure differential technology, the pressure loss under full load remains below 0.01 MPa, helping improve the overall efficiency of the compressed air system and reduce unnecessary energy loss.
To ensure stable drying performance and reliable long-term operation, the Low Pressure Differential Refrigerated Air Dryer should be used under the following recommended conditions:
- Applicable fluids: Compressed air, non-corrosive air
- Rated inlet pressure: 0.7 MPa
- Allowable pressure range: 0.6–1.0 MPa, other pressure levels customizable
- Rated inlet temperature: 45°C
- Maximum inlet temperature: ≤ 80°C
- Pressure loss under full load: < 0.01 MPa
- Outlet pressure dew point: 2°C–10°C
- Rated ambient temperature: 35°C
- Ambient operating range: 2°C–45°C
- Cooling method: Air-cooled or water-cooled optional
For the best operating result, the dryer should be installed in a clean and well-ventilated environment with stable inlet conditions. Proper system matching and suitable pre-filtration help maintain drying efficiency, reduce pressure loss, and protect downstream equipment.
