The compressed air first enters the pre-cooler for initial cooling, and then passes through the pre-cooling/reheating section of the high-performance 3-in-1 plate heat exchanger for further cooling. It subsequently enters the evaporator section, where it is rapidly cooled and the condensed moisture is separated.The treated low-temperature compressed air then returns to the pre-cooling/reheating heat exchanger, where it exchanges heat with the incoming hot compressed air. This reheats the dry compressed air before it is discharged from the dryer.The refrigeration system precisely adjusts the compressor speed according to changes in system load. The operating frequency is automatically regulated to match the actual air treatment demand, ensuring stable and energy-efficient operation.

Lingyu provides industrial compressed air treatment equipment for moisture removal, filtration, and on-site nitrogen generation.
Our product range includes refrigerated air dryers, desiccant air dryers, compressed air filters, and nitrogen generators for different airflow capacities, operating pressures, dew point requirements, air quality standards, and industrial applications.
Products are available in different capacities and configurations to support general manufacturing, automotive, electronics, pharmaceuticals, food processing, laser cutting, chemical processing, and other industrial compressed air applications.
A complete compressed air treatment system may require drying, filtration, and air or gas quality control depending on the application.
Lingyu provides four main product categories:
Each product category is designed for different air quality requirements and operating conditions.
Refrigerated air dryers remove moisture from compressed air by cooling the air until water vapor condenses into liquid water.
They are commonly used for general industrial compressed air systems where a stable, moderate pressure dew point is sufficient.
Refrigerated air dryers are typically selected when:
Lingyu provides both air-cooled and water-cooled refrigerated air dryers for different capacities and installation environments.
Desiccant air dryers remove water vapor from compressed air through adsorption.
They are typically used where significantly lower pressure dew points are required, including critical process air and instrument air applications.
Desiccant air dryers are commonly selected when:
Lingyu desiccant air dryer configurations include heatless, heated, blower purge, and other regeneration technologies for different energy and operating requirements.
Compressed air filters remove solid particles, oil aerosols, condensed water, and other contaminants from compressed air systems.
Filters may be installed before and after the air dryer depending on the compressor type, dryer configuration, and required air quality.
Compressed air filters are typically used to:
The appropriate filtration grade and filter combination should be selected according to the required air quality.
Nitrogen generators produce nitrogen on-site from compressed air.
PSA nitrogen generation systems separate nitrogen from compressed air and provide a continuous nitrogen supply based on the required purity, flow, and pressure.
Nitrogen generators are commonly used when:
Typical applications include laser cutting, food packaging, electronics, chemical processing, metal processing, and other industrial processes.
The correct compressed air treatment equipment should be selected according to the actual process requirement and operating conditions.
Key selection parameters include:
For compressed air dryers, airflow alone is not sufficient for accurate sizing. Temperature, pressure, dew point, and other operating conditions can affect the actual equipment capacity.
For nitrogen generators, nitrogen flow, purity, pressure, and compressed air conditions should all be considered.
Lingyu engineers can recommend a suitable product and configuration based on your operating requirements.
| Requirement | Recommended Product |
|---|---|
| General industrial moisture removal | Refrigerated Air Dryer |
| Low pressure dew point | Desiccant Air Dryer |
| Particle and oil removal | Compressed Air Filter |
| On-site nitrogen supply | Nitrogen Generator |
| General factory compressed air | Refrigerated Air Dryer + Filters |
| Very dry process air | Desiccant Air Dryer + Filters |
| High-purity process nitrogen | Nitrogen Generator + Air Treatment |
A refrigerated air dryer is commonly used for general industrial compressed air systems. A desiccant air dryer is typically selected when significantly lower pressure dew points are required.
Dryer capacity should be selected according to airflow, operating pressure, inlet temperature, ambient temperature, and required pressure dew point. Correction factors may be required when actual operating conditions differ from rated conditions.
In most industrial compressed air systems, filters are used before and/or after the dryer to remove particles, oil aerosols, and other contaminants. The exact filter arrangement depends on compressor type, dryer technology, and required air quality.
The main parameters include required nitrogen flow, nitrogen purity, outlet pressure, compressed air conditions, operating hours, and application.
Yes. Lingyu can provide dryers, filters, nitrogen generation equipment, and product configurations based on the operating conditions and air quality requirements of the compressed air system.
