What is a Air dryer?

An air dryer is a device used to remove moisture from the air. It is primarily employed to eliminate water vapor from compressed air, which is crucial in preventing corrosion, contamination, and malfunction of industrial equipment and machinery. Compressed air is often supplied in a high-temperature and high-humidity state, which, if not properly managed, can lead to condensation inside pipes and components. The air dryer works by cooling the compressed air, causing moisture to condense and be removed, ensuring dry air is supplied to the system.

There are two main types of air dryers:
１．Refrigerated Air Dryer: This type uses cooling coils to cool the compressed air and condense the moisture, which is then separated and removed.
２．Desiccant Air Dryer: This type uses desiccant materials (such as silica gel) to absorb moisture from the air, delivering dry air by removing the water vapor.

Air dryers are essential in industries where precise control of air moisture is required, such as manufacturing, medical equipment, and electronics production.

Application of Air dryer

１．Manufacturing Industry: In a factory that assembles electronic devices, an air dryer is used to remove moisture from the compressed air to prevent any moisture from damaging the sensitive components.
２．Food Processing: In food processing plants, an air dryer ensures that the air used for packaging or handling food products remains dry, preventing mold growth and ensuring the products stay fresh.
３．Pharmaceutical Production: In the production of medicines, clean, dry air is necessary to maintain the integrity of the products and avoid contamination. An air dryer ensures that the air supplied to the production line is free from moisture.
