KXD series Heatless Regenerative Desiccant Air Dryer

KXD series heatless regenerative desiccant air dryer offers a simple, reliable and economical way to remove water from compressed air, and it is able to provide high quality compressed air for many instruments with remarkable reliability. After being processed by this machine, the compressed air usually has a pressure dew point of -40? at the outlet, and this value can be even lowered to -70?. Our product is especially suitable for compressed air lines with ambient temperature of 0? or lower, or places that require compressed air with extremely low water content.

Working Principle

The working process of heatless regenerative desiccant air dryer depends on the pressure swing absorption theory, and the work flow is as follows.

There are totally two desiccant towers, and they are filled with activated alumina. When saturated wet air flows up through one tower, the water content in compressed air is absorbed to the surface of activated alumina, and the dried airflow exits the tower and moves to distribution system. A proportion of this dried air flows into the other tower through an orifice and is depressurized to atmospheric pressure to regenerate the wet desiccant, and moisture in the desiccant is absorbed and purged to atmosphere.

Five minutes later, wet air changes its way from the original tower to the other tower, and this is achieved with the help of our control system. This switching process will repeat all the time to remove water in compressed air continuously.
