500 to 4300 scfm @100 psig
Pressure dew point: to -40 °F
Kaeser externally heat-regenerative blower purge desiccant dryer produces dew points as low as -40°F. 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.
The Eco Control 3 controller accurately controls inlet and purge valves which direct wet compressed air to the regenerated tower, and heated purge air to the tower in need of regeneration. The controller also includes system monitoring and optional energy savings capabilities. The process of adsorption and desorption can be repeated several thousand times before the desiccant must be replaced.
Important features and advantages:
- Outstanding energy savings by heating atmospheric air for regeneration and using no purge air
- Reliable controls and instrumentation meet NEMA 4 standards
- Options for energy savings and dew point monitoring/control
- ASME pressure relief valve
