Compressed air dryers are used to remove water and other contaminants from compressed air. Compressed air dryers use technologies such as refrigeration, desiccant adsorption, and membrane filtration to remove contaminants, particularly water, from the air.. Major groupings include refrigerant (which removes the water by cooling the air) force condensation, and desiccant (which adsorbs theRead More

In general, dryers are either suitable for batch or continuous operation. A number of the more common types are listed in Table 1, where an application rating based on practical considerations is given. In the following review, some of the factors likely to influence selection of the various types are discussed for particular applicationsRead More
There have been many attempts to provide first guides for the selection of a dryer for a particular job. Simple decision trees are set out by van't Land (1984) for batch and continuous dryers, and these are reproduced in Figure 5 and 6. More advanced methods based on expert systems are currently being developed [Kemp (1994)]Read More
For general manufacturing processes, the refrigerated dryer option probably will be sufficient. Desiccant dryers provide the driest air for critical applications, but have higher up-front and energy costs. In making the selection, users should consider if the pipe work associated with the process is located in a conditioned or unconditioned spaceRead More
