Compressed Air is polluted with Dirt Particles, Water, Oil, Oil Vapor and Condensate. These contaminants result in High Maintenance Costs, premature wear, spoiled products and the failure of control systems.
The DHA Series Externally Heat Reactivated Air Dryers & the DBA Series Blower Purge Air Dryers will effectively remove these contaminants. Pressure Dewpoints ranging from -40˚F (-40˚C) to -100˚F (-70˚C) are achieved by directing the flow of Saturated Compressed Air over a Bed of Desiccant. The Adsorption Principle used in this design is simple, robust and flexible. Continuous drying is accomplished by the operation of Two Desiccant Towers. Compressed Air is dried through one tower while the other desiccant tower is being regenerated.
The Regeneration Heating Cycle of the DHA Series Desiccant Dryer is accomplished using a dry air purge flow heated by an external electric heater (other means of heating are optional). With the DBA Series, Regeneration Heating Cycle of the desiccant is accomplished using a hot air flow delivered by an Atmospheric Blower and External Electric Heater (other means of heating are optional). The Regeneration Cooling Cycle is performed using the same flow of Dry Compressed Air taken from the dryer outlet to ensure dewpoint performance. A high level of reliability is achieved by the use of proven engineering technology and components.
Parker Domnick Hunter DTA Series Heatless Adsorption Dryers remove Water Vapor from Compressed Air through a process known as Pressure Swing Adsorption (PSA). Pressure dewpoints ranging from -40°F to -100°F are attained by directing the flow of Saturated Compressed air over a Bed of Desiccant. The most commonly used desiccant is Activated Alumina, a spherical shaped, Hygroscopic Material, selected for its consistent size, shape and extreme surface to mass ratio.
The Traditional Adsorption Principles used in this design are simple, robust and flexible using compressed air for regeneration thereby eliminating any need for an outside energy supply.
