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.

Air cooled refrigerated air dryers remove moisture from compressed air by cooling the air until water vapor condenses into liquid water. Heat from the refrigeration system is discharged through an air-cooled condenser, eliminating the need for an external cooling-water supply.
Lingyu AH Series air cooled refrigerated air dryers are designed for industrial applications with higher compressed air inlet temperatures, with a rated inlet temperature of 50°C and maximum inlet temperature up to 80°C.
The AH Series covers airflow capacities from 1.5 to 110 m³/min, suitable for small to large industrial compressed air systems.

Actual dryer capacity can change when operating pressure, inlet temperature, or ambient temperature differs from the rated conditions.
Select the dryer according to actual operating conditions rather than compressor airflow alone.
Key parameters include:
For high-inlet-temperature applications, the AH Series can handle compressed air inlet temperatures up to 80°C, subject to the specified operating conditions.
Air cooled refrigerated dryers discharge condenser heat into the surrounding environment, so adequate ventilation is important.
Install the dryer indoors on a level concrete floor, keep the condenser air inlet and outlet unobstructed, and prevent hot discharge air from recirculating into the cooling-air inlet.
For the AH Series, a minimum clearance of approximately 1.5 m around the unit is recommended for ventilation and maintenance access.
For installations with limited ventilation, a water-cooled refrigerated air dryer may be more suitable.
| Factor | Air Cooled | Water Cooled |
| Cooling medium | Ambient air | Cooling water |
| Cooling water required | No | Yes |
| Installation | Simpler | Requires water circuit |
| Ventilation requirement | Higher | Lower |
| Infrastructure requirement | Lower | Higher |
| Limited compressor-room ventilation | Less suitable | More suitable |
| Typical use | General industrial systems | Large / demanding systems |
Choose an air cooled refrigerated air dryer when cooling water is unavailable and adequate ventilation can be provided.
Consider a water cooled refrigerated air dryer for large-capacity systems or installations where compressor-room heat dissipation is limited.
The rated inlet temperature is 50°C, with a maximum allowable inlet temperature of 80°C.
The AH Series specifies a pressure dew point of 2–10°C, depending on operating conditions.
The specified pressure drop is ≤0.025 MPa.
The rated ambient temperature is 32°C, with an operating range of 2–45°C.
Selection should consider airflow, working pressure, inlet temperature, ambient temperature, and required dew point. If actual conditions differ from the rated conditions, dryer capacity should be checked accordingly.
