According Air Options, its compressed-air dryers use a simple two-stage, water-evaporation process to extract water from the compressed-air stream by cooling the air, causing the water vapor to condense out. As hot, moist air from the compressor flows through a tube-in-shell heat exchanger, the air is cooled and water vapor condenses on the inside surface and is evacuated. These systems, says the manufacturer, can function routinely with input temperatures as high as 250F, and can accommodate temperatures as high as 350F with no damage. The systems can be mounted directly to the compressor or to the receiver, depending on the size of the compressed-air system. The air dryers have a maximum operating pressure of 200 psi, and are available in sizes from 8 to 1,500 scfm.
