Low pressure differential refrigerated dryer

Low pressure loss: The precooler is a newly designed annular pipe structure, with three times more pipes than the traditional precooler. The sufficient flow cross-sectional area of ​​compressed air further reduces the pressure difference, and the pressure loss of the whole machine is less than 0.1bar;

Low dew point: The new optimized integrated three-in-one design and unique water separation design make the dew point more guaranteed;

Intelligent control: Standard PLC and touch screen, intelligently control the compressor cooling capacity output by sensing the evaporation load, ensuring that the machine runs in the best state, and standard RS-485 communication interface.

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.

In Malaysia’s hot, humid, and high-rainfall environment, compressed air systems are more exposed to moisture, condensation, corrosion, and unstable pneumatic performance. The Low Pressure Differential Refrigerated Air Dryer is well suited for industrial applications that require stable moisture removal together with minimal pressure loss, helping improve overall compressed air system efficiency in continuous-duty operation.

The Low Pressure Differential Refrigerated Air Dryer is suitable for applications in Malaysia such as:

  • Electrical & Electronics Manufacturing – Provide clean and dry compressed air for production support, assembly areas, and utility air systems where moisture control and stable system efficiency are important.
  • Food and Beverage Processing – Suitable for packaging, conveying, and process air applications where dry compressed air supports hygiene, consistent production, and reliable day-to-day operation in humid conditions.
  • Printing, Packaging, and Industrial Automation – Help maintain clean and stable compressed air for printing systems, packaging lines, and automated equipment where low pressure loss improves downstream pneumatic performance. This is a grounded application inference based on the product’s low-pressure-differential design and Malaysia’s manufacturing mix.
  • Laboratory Analyzers and Scientific Support Air – Suitable for laboratory systems and analytical support equipment where stable air dryness and dependable utility air are required for reliable operation. This is a grounded application inference based on the product’s standard dew point range and Malaysia’s humid climate.
  • Electronics Manufacturing and Sensitive Production Lines – Help reduce moisture-related instability in production environments where compressed air quality affects equipment protection and product consistency.
  • Medical, Printing, and Utility Air Support Systems – Provide dry compressed air for selected medical support, printing, and pneumatic utility applications where low pressure drop and reliable air quality are both important. This is a grounded application inference from the product’s low-pressure-loss positioning.
  • Machinery, Metal, and General Manufacturing – Used in pneumatic tools, automation systems, and centralized compressed air networks where dependable moisture control and reduced pressure loss help protect downstream equipment and improve system efficiency.
  • Factories Focused on Compressed Air Efficiency – Especially suitable for plants that want to reduce unnecessary energy loss caused by pressure drop while maintaining stable refrigerated drying performance. This is an inference directly based on the product’s “low pressure differential” design.
