DHA Series Heated Adsorption Dryers
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. DHA Series adsorption dryers will effectively remove these contaminants. 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 desiccant is accomplished using a dry air purge flow heated by an 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.
