Refrigerated dryers are one of the key pieces of equipment in compressed air post-processing. Through a closed-loop refrigeration cycle, they efficiently and economically dry and clean compressed air, ensuring the stable operation of downstream pneumatic equipment and production processes.
Product features
1. Efficient Moisture Removal: Effectively reduces the dew point of compressed air to 3-10°C, reducing moisture corrosion on equipment.
2. Energy-Saving and Environmentally Friendly: Compared to adsorption dryers, this dryer offers lower energy consumption and more economical operating costs.
3. Simple Maintenance: No frequent replacement of adsorbents (such as molecular sieves) is required; only regular cleaning of the condenser and drain is required.
4. Wide Range of Applications: Suitable for most industrial applications requiring dry air.
5. High Stability: High continuous operation capability, suitable for extended operating environments.

Application Industry
Refrigerated dryers are widely used in industries requiring dry compressed air, including:
Manufacturing: pneumatic tools, spray painting equipment, CNC machine tools
Food and beverage: packaging machinery and filling equipment (to prevent moisture contamination)
Pharmaceutical: pharmaceutical equipment and sterile production environments
Electronics: PCB production and precision instruments (to prevent moisture damage)
Chemical: gas transportation and reactor air supply
FAQ
1. What is the difference between a refrigerated dryer and an adsorption dryer?
Refrigerated dryers: Remove water through refrigeration, with a dew point of 3-10°C, making them suitable for general industrial use.
Adsorption dryers: Utilize adsorbents (such as molecular sieves) for deep water removal, achieving dew points as low as -40°C, making them suitable for extreme drying needs.
2. What maintenance is required for a refrigerated dryer?
Drain condensate regularly (check the automatic drain).
Clean the condenser (to prevent dust from clogging and affecting heat dissipation).
Check the refrigerant pressure (to ensure the refrigeration system is functioning properly).
3. Will a refrigerated dryer freeze? How can this be avoided?
If the inlet temperature is too low or the load is too high, the evaporator may freeze.
Solution: Install a precooler, adjust the expansion valve, or choose a model with hot gas bypass.
4. How do I choose the right refrigerated dryer?
Flow matching: Select the model based on the compressor's discharge capacity (m³/min). Inlet air temperature: Generally required to be ≤45°C; special design is required for high-temperature environments.
Target dew point: Select according to industry requirements (3-10°C is sufficient for general industrial applications).
5. Can a freeze dryer remove oil?
It cannot completely remove oil; it can only reduce the amount of liquid water. If the compressed air contains oil, an oil-water separator or activated carbon filter will be required.
