Having water inside a compressed air method is very damaging to the entire system. Water inside the system corrodes pipes, valves, and even causes outdoor airlines to freeze. If water exists in a compressed air system, a compressor dryer must remove the water. Three different stages of water exist in compressed air; they're liquid, vapor, or mist. There are different types of available air compressor dryers, each of use specific functions to eliminate water from the compression system. - Air Compressor Maintenance
The most commonly used dryer can be a refrigerated one. Refrigerated Dryers have two separate functions, the first is to use the air being released to cool down the incoming hot air, and by increasing the temperature of the outgoing air prevents condensation. A newer set of compressors which can be being produced with dryers built-into the compressor. These have mixed reviews, and have yet to gain popularity among users. While this is the main type of air compressor dryer used, you will find others available.
A deliquescent dryer is really a pressure vessel that has a tablet or powder at the base that slowly dissolves in to a liquid as it absorbs water from the air compressor. Once every one of the power has been changed into a liquid the pressure vessel is emptied, and another tablet is inserted. A deliquescent Air Compressor Dryer is straightforward to use, and is effective for remote work sites, and workers that moved around to various work sites. Another type of air compressor dryer will be the also uses a pressure vessel, but utilizes substances like silica gel. The purpose of the silica gel is to lower the temperature needed for the water to condensate.
Each one of these help get rid of water from compressed air, and each has their uses. It depends about the process that works best for each compressor as well as the environment the dryer will be used in. These dryers use a specific use for processes, and tools that require dry air only. This includes some truck brake systems, air tools, and painting tools that require air compression- Air Compressor Maintenance
