A refrigerated air dryer removes moisture from compressed air by cooling it to near-freezing temperatures, condensing water vapor into liquid for discharge. It delivers clean, dry air for industrial applications.
Product features
Stable Pressure Dew Point: Provides consistent +2°C to +10°C PDP, unaffected by ambient temperature changes.
Low Operating Cost: No purge air loss, saving energy compared to desiccant dryers. High-efficiency heat exchangers reduce refrigeration load.
Easy Maintenance: No desiccant replacement; automatic drains minimize manual work; modular design simplifies servicing.
Wide Adaptability: Handles inlet temperatures up to 55°C (80°C with pre-cooler) and pressures from 0.6 MPa to 1.6 MPa+.
Compact & Durable: Space-saving vertical designs with corrosion-resistant materials.
Intelligent Control: Energy-saving mode adjusts operation based on load; fault self-diagnosis for early warnings.

FAQ
Q1. How does a refrigerated dryer work?
A. A refrigerated dryer uses a refrigeration cycle to lower the temperature of compressed air, condensing the water vapor into liquid water and discharging it. The dried air is then heated to room temperature and discharged.
Q2. Why is there still water in the air at the dryer outlet?
A. Possible causes: Overload, insufficient refrigerant, drainer failure, or excessively high ambient temperature.
Q3. What routine maintenance does a refrigerated dryer require?
A. Regularly drain the air, clean the filter, check the refrigerant pressure, and clean the condenser.
Q4. What should I do if the refrigerated dryer is noisy during operation?
A. Check the compressor, fan failure, or pipe vibration.
Q5. Possible reasons why the refrigerated dryer may not start?
A. Power supply problem, high-pressure protection, or low-pressure protection.
