| Description | Kaeser externally heat-regenerative blower purge desiccant dryer produces dew points as low as -40ºF. Twin desiccant beds of activated alumina alternate between drying and regenerating, with regeneration being accomplished with heated ambient air at just above atmospheric pressure. The heated ambient air readily drives adsorbed moisture off of the desiccant preparing it for another adsorption cycle. The moisture-laden regeneration air exhausts to atmosphere during the regeneration process. KBD dryers can regenerate with little (about 1%) or no process (purge) air loss. | |||||||||

| Additional Information |
Solid state logic accurately controls inlet and purge valves which direct wet compressed air to the regenerated tower, and heated ambient air to the tower in need of regeneration. The process of adsorption and desorption can be repeated several thousand times before the desiccant must be replaced. 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 freez-ing 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 |
Average Heater kW (fixed cycle) = [kW required to produce 280 ºF temperature rise] x [235 min. max heat time] / [240 min drying time]. Average Blower kW (fixed cycle) = [Blower kW] x [235 min. max heat time] / [240 min dryer time]. Average Dryer kW (fixed cycle) = [Average Heater kW] + [Average Blower kW] Actual kW is less and proportional to the average water load presented to the dryer. |
