How Do Air Dryers Work?

Desiccant, and Refrigerated Air Dryers

The basic function of the air dryer is to remove moisture from the air by cooling it with a refrigerant. Thus, the water vapor is condensed, and the air can be compressed. The result is dry compressed air, which can be used in compressed air equipment without causing any damage.

Compressed air dryers are fundamental in a large group of mechanical offices. That requires a normal stock of dry, compacted air. These dryers are basic in modern activities on the grounds that the presence of dampness in mechanical air. It can harm pneumatic frameworks, cause freezing in pipelines. Advance erosion in metallic parts, and so on. 

A wide scope of instrument air dryer types is accessible available today. Understanding the various kinds of air dryers and their standards of activity will allow you to pick the ideal packed air dryer for your remarkable application. 

What Is a Compressed Air Dryer?

A compressed air dryer is a piece of gear intended to isolate water fume or dampness  from mechanical cycle air. In the regular framework, a blower attracts sticky air and packs it, which raises the air temperature and afterward cooling the air by consolidating water fumes out of the unit. 

In any case, there are alternate approaches to accomplish detachment. The principle kinds of air dryers incorporate the refrigerated, desiccant-type, and layer type air dryer. 

Refrigerated Air Dryer Working Principle


Refrigerated air dryers quite possibly the most well-known type utilized in mechanical applications because of their simplicity of upkeep and relative expense adequacy. They are appropriate for air-drying applications without uncommon prerequisites, for example, a base dew point. 

The refrigerated air dryer working guideline depends on dehumidifying air by quickly cooling it, gathering it, and depleting off the dampness. The activity resembles that of a homegrown cooler or home cooling system. 

Refrigerated air dryers de-humidify air through the accompanying stages: 

Warm, wet air enters the dryer, which cools it quickly to about 3°C in a refrigeration unit. At this temperature, the water fume noticeable all around consolidates into unadulterated water, which gathers in a water trap and took care of into release lines. The warm, vaporous refrigerant cools and recovers in a condenser. 

The dry air in the chamber warm to room temperature and take care of through an outlet. 

Additional refrigerated air dryers are accessible with cycling and non cycling.

Cycling dryers are 100% process cycle machines that can keep up with the dew point at a consistent temperature. 

Non-cycling dryers work by discontinuously closing down and restarting to keep up with the necessary temperature. 

The two variations are valuable in various applications, in spite of the fact that cycling types will in general increase support costs.
