A refrigerated air dryer is a post-processing unit that uses a closed-loop refrigeration cycle to remove moisture from compressed air. It ensures stable operation of pneumatic equipment and downstream processes.
Efficient Moisture Removal
Maintains a stable pressure dew point of 2–10°C, effectively removing liquid water and most water vapor to prevent pipe corrosion and equipment damage. Ideal for general industrial applications such as pneumatic tools, spray painting, and packaging.
Energy Efficient & Eco-Friendly
No consumables required—only electrical cooling. Lower operating costs compared to adsorption dryers. Intelligent temperature control adjusts cooling power based on load to reduce energy consumption.
Simple & Reliable
No complex adsorption towers means fewer failure points. Routine maintenance involves only condenser cleaning and filter changes. Modular design allows for easy servicing and minimal downtime.
Cost-Effective & Versatile
Suitable for small to medium flow rates (1–200 m³/min). Low initial investment makes it an economical choice when strict dew point requirements are not needed.

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.
