Single Tower Desiccant Dryer

DRY AIR
Kaeser’s KDF series single tower desiccant air dryer significantly lowers compressed air dew points. With a simple flow-through design, the dryer economically produces atmospheric dew points as low as -45°F.

The KDF’s modular design allows the user to easily install the required pre-filter. The KDF is ideally suited for point of use applications needing small volumes of extremely dry air.

Economical

The KDF is a very affordable and economical compressed air dryer that requires no electricity. The silica gel desiccant can be reused which reduces operating costs. Simply bake the silica gel in an oven for the prescribed time and temperature to regenerate the desiccant.

Operation

Compressed air enters the desiccant dryer housing and flows downward through the bed of silica gel desiccant. As the desiccant bed becomes saturated, the color of the desiccant indicator changes from blue to white. In the bottom of the housing, the compressed air flows upwards through an integrated dust filter and into an outlet tube where it is directed to the discharge port of the dryer housing
