Adsorption drying — Why? Compressed air is an important process and energy medium applied in almost all areas of industrial production. The atmospheric air taken in contains contaminants, dirt particles and humidity, i.e. water vapor, which condensates in compressed air pipes. This condensation can lead to considerable costs (corrosion, freezing). These costs can be avoided by using the applications of the Donaldson Ultrapac 2000 heatless desiccant dryer. This complete purification system includes a prefilter, dryer, afterfilter, control system, and automatic condensate drain and silencer.
The prefilter retains solids and condensate (oil/water mixture) up to residual oil content 0.03 ppm. The adsorption dryer next in line adsorbs the moisture in the compressed air up to a pressure dew point of -40°F. Finally, in the afterfilter, remaining particles from the drying agent are retained.
