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.

The Low Pressure Differential Refrigerated Air Dryer is well suited for industrial compressed air systems in the Middle East that require stable moisture removal, low pressure loss, and dependable long-term utility air performance. In regional operating conditions that may include high ambient temperatures, dust exposure, and strong pressure on energy and water efficiency, a low pressure differential design can help improve overall compressed air system efficiency while maintaining a stable pressure dew point of 2°C to 10°C. It is best positioned for general plant utility air and production-support air, rather than for ultra-low-dew-point or specialty gas applications.

Application Note for the Middle East
For Middle East projects, this model is especially suitable where users want to reduce pressure loss while maintaining reliable refrigerated drying performance. Air-cooled versions are more suitable where good indoor ventilation can be maintained and cooling water is not readily available, while water-cooled versions are more appropriate for larger industrial sites with established utility support. Because regional conditions often include high heat, dust exposure, and strong pressure on water resources, the dryer should be installed in a clean, well-ventilated indoor environment and matched with proper pre-filtration and system sizing.
