Water in a compressed air system is very harmful for the entire system. Corrosive water system piping, valves, and even cause the airlines to freeze outdoors. If water exists in a compressed air system, dryers, compressors are needed to remove water. Three different phases of water exist in compressed air; they are liquid, vapor or mist. There are many different types of dryer air compressor is available, and each specific use function to remove water from the compression system.
Dryer most commonly used is a fridge. Refrigeration dryers have two separate functions, the first is to use air to cool release hot air, and by increasing the temperature of the air to prevent condensation. A newer set of compressors are manufactured with integrated dryer into the compressor. Those with mixed reviews, and was not popular among users. While this is the main type of dryer air compressor is used, there are others available.
A chemical leak dryer is a pressure cooker with a pill or powder at the bottom that slowly melts into the liquid as it absorbs water from the air compressor. When all power has been turned into a liquid container is emptied, and the other tablet is inserted. An air compressor dryer melted chemical is easy to use, and works great for remote work sites, or for workers to move around the different work sites. Another type of dryer air compressor was also used a pressure vessel, but the use of substances such as silica gel. The purpose of the silica gel is to lower the temperature required for condensation.
Each of these helps remove water from the compressed air, and each have their uses. It depends on the process that works best for each compressor and dryer environment will be used in. The dryer will be used exclusively for the processes, and tools that require only dry air. This includes a number of truck brake systems, tools, and painting tools require air compressor.
