Compressed air dryers - compressed air is widely used in industries and has ample utility. A typical compressed air system consists of compression, storage, cooling, and distribution equipments.

It is simple to use, but complicated and costly to create. - the type of compressor most likely to be used for an industrial compressed air system depends largely on size, and reliability requirements, cost. Compressed air dryers are used for the removal of water and other contaminants from compressed air. The application norm of compressed air dryers involve climatic conditions, the degree of air dryness needed, cost and consistency. One of the most effective ways of drying compressed air is to cool it, collect the moisture that condenses and finally heat the air to the ambient temperature. Besides, they also use technologies like membrane and in - line compressed air dryers. Compressed air dryers use tools such as refrigeration, and membrane filtration, desiccant adsorption to remove contaminants, from the air, particularly water.

The air can be dried in single or multiple stages to prevent tool decomposition and other problems associated with water. - drying capacity is the maximum volume of air through dryer which is usually at 100 psig. Anybody looking for compressed air dryers must take into consideration the drying capacity, dew point, pressure, motor power and operating temperature. The pressure should be at the highest level i. e. the maximum rated inlet pressure of dryer. It describes how much water vapour is present and gives the measure as to how cold the compressed air can get before the formation of liquid water. Dew point is a measure of dryness. Motor power is a reference value often used to approximate dryer size.

The operating temperature is the full - required range of ambient operating temperature. - pressure and capacity. The compressed air dryers used in industries can be categorised into three main groups. Refrigerant dryers cool the incoming air to a temperature or dew point of 1 - 3� C, causing a large portion of the water to condense and to be collected by a separator. They are as follows: Refrigerant dryers, Regenerative desiccant dryers, Deliquescent desiccant dryers. The dew points achieved in deliquescent desiccant dryers are approximately 10� C below the temperature of the incoming air. The desiccant dissolves with the water and collects in the bottom of the tank which can be easily drained away.

The desiccant is usually derived from salt or chloride which has a stronger attraction for water than the compressed air being passed through it. - regenerative. desiccant dryers use a desiccant such as silica gel to attract and absorb moisture from the air, achieving pressure dew points in the range of minus 40� c. Even with the super - low temperatures achieved as the compressed air does its work. These lower dew points guarantee that water never condenses in modern systems. Dryers are very much essential for the efficient functioning of compressed air system. Air systems without compressed air dryers severely lessen the longevity of any equipment they operate.
