	Web Price QUOTE

Kaeser Adsorptive Desiccant dryers (KAD Series) employ a heatless regenerative design to produce pressure dew points as low as -100 ºF. Solid-state controls with adjustable cycle timers allow KAD Series dryers to be easily adapted to user requirements. The optional purge saver control dramatically increases efficiency at reduced flows, and includes active tower lights and a switching failure alarm.

KAD dryers are ideally suited for moisture sensitive applications such as electronics and pharmaceutical manufacturing, food processing and brewing.

Additional Information

The right dryer for you
Most compressed air applications can achieve the required air quality by using a refrigerated dryer in combination with proper filtration. However, in cases where compressed air is exposed to freezing temperatures or where the product, process, or equipment is highly sensitive to moisture, Kaeser offers a complete line of desiccant dryers specifically designed to meet low dew points and deliver energy savings.

Innovation you can trust
With a cutting edge research and development team committed to building industry-leading products, Kaeser continues to deliver better solutions to meet our customers' compressed air needs. Kaeser's expertise and world-wide reputation for superior reliability and efficiency offer great performance and peace of mind.

Quality in every detail
Desiccant dryer performance and reliability are driven by component quality. Kaeser's valves and actuators are designed for consistent dew point performance and low pressure drop. Additionally, desiccant bed symmetry is selected to ensure uniform flow distribution and maximize contact time, while the spherical activated alumina desiccant allows for long service life and minimizes dusting. It also has a high surface-to-volume ratio and great affinity for water vapor for superior adsorption.

Savings with proper application
Proper planning with the help of Kaeser's system design engineers can save you money on capital and energy costs. Desiccant dryers have a higher purchase price and overall operating costs than refrigerated dryers and should be applied to the portions of a system requiring dew points below that of a refrigerated dryer. Kaeser can design a system that will efficiently deliver air quality suitable for your application.

Desiccant dryer basic operation
Kaeser desiccant dryers use the principles of adsorption and desorption and alternately cycle the compressed air through twin desiccant towers. As the vapor-laden air flows through one tower, the moisture is adsorbed onto the desiccant. Meanwhile, in the other tower, "purge air" flows through, evaporates the water on the desiccant, and carries it out of the tower as vapor.

Note

KAD dryer inlet flow capacities are established in accordance with CAGI (Compressed Air and Gas Institute) Standard ADF-200: Inlet air pressure 100 psig, inlet air temperature 100 ºF, saturated.

The purge flow rate of any pressure swing (heatless) desiccant dryer is not constant throughout the purge cycle. The purge cycle consists of a maximum purge flow period when the purge valve is open and a reduced flow period during repressurization. The total air consumption during the purge cycle is the average purge flow and is based on a 10 minute cycle time (-40 ºF PDP).

Maximum working pressure: 150 psig standard; 250 psig optional. Maximum working pressure to 500 psig available for most models. Consult factory.
