All About Refrigerated Air Dryers

The air around us naturally contains water vapor, and when it is drawn into an air compressor, the water vapor is compressed along with the air. 

Therefore, compressed air refrigeration dryers are the ideal solution for removing unwanted and potentially harmful moisture. You can also pop over to this website to know more about refrigerated air dryers.

How do refrigeration dryers work?

As the name suggests, refrigeration dryers work by cooling the air, similar to household refrigerators. With the air to the refrigerant exchanger, the compressed air is cooled to the dew point at a pressure of about +3 °C (the temperature at which water vapor no longer condenses in the compressed air), leading to condensation of the moisture content and conversion to water. 

This moisture is then drained, leaving the compressed air devoid of moisture. After this cooling and condensing phase, the compressed air is reheated by a second heat exchanger as it leaves the dryer.

What you should consider before installing a refrigeration dryer

When considering investing in a refrigerated air dryer, there are a few important points to keep in mind. 

Make sure you know and understand the answers to these questions beforehand to avoid investing in the wrong model or type of refrigerator dryer which could lead to bigger problems.

The maximum airflow that can flow through your dryer must be higher than the value your air compressor can provide. If your refrigerant dryer is too small, it can result in a large pressure drop, higher energy costs, and may not reach the desired dew point.
