KXD Series Heatless Regenerative Air Dryer is a kind of simple, reliable and economical method for removing water vapor from compressed air. The normal outlet pressure dew point is -40°C, lowest pressure dew point can be -70°C .the KXD Series air dryer is ideal for applications where compressed air lines are exposed to blew zero ambient temperatures, or where special processes require air at an extremely low relative humidity. This unit provides instrument quality air and is designed for maximum reliability and long, trouble-free service.
Heatless air dryer is based on pressure-swing-adsorption technology. There are two desiccant towers filled with activated alumina, as saturated air flows up through the tower , its moisture content adheres to the surface of the activated alumina beads. The dry air is then discharged from the tower into the distribution system.
After 5 minutes of operation on one tower the flow is switched to the other tower through the use of a timed system of directional valves. A portion of the dried compressed air is diverted through an orifice, expanded to atmospheric pressure, and directed into the regenerating tower, where the moisture accumulated during the drying cycle is stripped off and purged to the atmosphere.
