Why Choose Ad 15–4200 Refrigeration Dryers?

Moisture in compressed air can cause corrosion, pneumatic equipment problems and production-quality issues. The AD 15–4200 range uses refrigeration technology to cool moisture-laden compressed air, condense water vapour and remove the resulting condensate before the air reaches the downstream network.

As a non-cycling design, the refrigeration circuit maintains continuous refrigerant flow, providing straightforward and stable operation for industrial compressed-air systems.

The refrigeration dryer removes moisture by cooling compressed air below the temperature at which water vapour condenses.

 

Step 1 – Moist Compressed Air Entry
Warm, moisture-laden compressed air enters the dryer.

 

Step 2 – Air-to-Air Pre-Cooling
Incoming compressed air exchanges heat with the outgoing dry air.

 

Step 3 – Refrigeration Cooling
The pre-cooled air passes through the air-to-refrigerant heat exchanger.

 

Step 4 – Moisture Condensation
As the compressed air temperature falls, water vapour condenses into liquid water.

 

Step 5 – Condensate Removal
The collected moisture is discharged through the zero-loss electronic drain.

 

Step 6 – Air Reheating
The dry compressed air is reheated through the air-to-air heat exchanger.

 

Step 7 – Dry Air Delivery
The treated air returns to approximately room temperature, helping prevent condensation in downstream piping.

Stable Non-Cycling Operation

The refrigeration circuit operates continuously, providing straightforward and dependable drying for compressed-air systems with relatively steady demand.

 

Reliable Moisture Removal

Cooling compressed air causes water vapour to condense, allowing the moisture to be removed before it reaches downstream equipment.

 

Up to +4°C Pressure Dew Point

The current specification provides a pressure dew point of up to +4°C / 39°F, suitable for many general industrial applications.

 

Zero-Loss Condensate Drain

The electronic drain removes accumulated condensate without continuously venting compressed air, helping preserve system efficiency.

 

Hot-Gas-Bypass Protection

The hot-gas-bypass valve helps prevent ice formation during low-airflow conditions, supporting stable dryer operation.

 

Real-Time Dew-Point Monitoring

The digital controller provides real-time pressure dew-point information, allowing operators to monitor dryer performance directly.

 

Wide Capacity Range

With models from 22 to 7,200 m³/h, the range can accommodate applications from smaller workshops to large industrial compressed-air installations.

 

Environmentally Considered Refrigerant

The referenced range uses R513A refrigerant, selected for lower global-warming impact compared with older refrigerant options.

 

High-Temperature Air Handling

AD 15–270 models are specified for inlet temperatures up to 55°C, while AD 355–4200 models support up to 60°C.
