All You Need To Know About Refrigerated Air Dryers

There are many different types of compressed air dryers on the market and many different uses for compressed air drying. Most of the time, this application requires that the air does not contain condensed water (free liquid), which will interfere with the operation of the tool and cause corrosion, which will shorten the life of the tool. 

Refrigerated air dryers are usually chosen for this application. To get more details about refrigerated air dryers you may see it here.

They remove moisture from the compressed air by cooling the supply air to a level within the design dew point limits, separating the condensate, and then removing it.

Refrigerated air dryers cool the air and remove condensed moisture before it is passed through the distribution system. They typically lower the air dew point to 35-40°F, which is sufficient for most applications. 

As long as the temperature in the system never drops below the dew point, no condensation occurs. Typical benefits of refrigeration dryers include low initial capital costs, relatively low operating costs, and low maintenance costs. This makes it a common solution in industrial compressed air systems.

It should be noted that expansion can occur as air flows through fittings, restrictions on pipes, regulators, tool openings, and other equipment. 

The expansion of the air causes cooling, which can lead to a cold point where condensation can still form, although the room temperature can be higher than the nose dew point of the air dryer.
