A refrigerated compressed air dryer is a device used to remove moisture from compressed air by lowering its temperature. It is a widely used type of refrigerated compressed air dryer in various industrial applications where the presence of moisture can lead to equipment damage, corrosion, and decreased efficiency.
Refrigerated compressed air dryers are the most commonly used dryers in the industry and consist of an air-to-air heat exchanger and an air-to-refrigerant heat exchanger. The heat exchangers remove moisture from your compressed air by condensation of water within.This is essential to protect compressed air systems and every piece of equipment fed by compressed air from the harmful effects of moisture.
The most important criterion is to keep the relative humidity of compressed air below 50%.
Both air-cooled and water-cooled refrigerant dryers are available. Basically, the dryers cool down the warm wet air coming from the compressor, When the temperature of compressed air reduces, moisture condenses and is drained from the compressed air with the help of a high-efficiency water separator.
After that, compressed air is reheated to around room temperature so that condensation does not form on the outside of the pipe system. This heat exchange between ingoing and outgoing compressed air also reduces the temperature of the incoming compressed air, and as such reduces the required cooling capacity of the refrigerant circuit.

Usually compressed air contains 100% vapor, these vapors are condensed together when the air would be cooled,The condensed water not only damages the compressor system,reduces tool efficiency,but also
destroys your terminal products,corrodes piping and increases your maintenance costs.
More than 90L water will enter into the compressor system everyday if without the air dryer. NAILI refrigerated compressed air dryer removes appromimately 90% of water and ensures your application in good performance.
