A refrigerated air dryer removes moisture from compressed air by cooling it, condensing water vapor into liquid that is then drained. It outputs dry air with a stable pressure dew point of 2–10°C.
Core Features
✅ Efficient Moisture Removal
Provides stable dew point (2–10°C), effectively removing liquid water and most vapor. Ideal for pneumatic tools,
spray painting, and packaging.
✅ Energy Efficient & Low Operating Cost
No consumables; only electricity required. Intelligent temperature control reduces power use based on load,
lowering long-term costs.
✅ Simple Structure, Easy Maintenance
No adsorption tower; low failure rate. Routine maintenance is limited to condenser cleaning and filter replacement.
✅ Wide Applicability & Cost-Effective
Suitable for small to medium compressed air systems (1–200 m³/min). A budget-friendly alternative to adsorption
dryers when ultra-low dew points are not required.

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.
