Constant dry air at a guaranteed dewpoint

Removing moisture from compressed air with a pressure dewpoint of down to -70°C, Atlas Copco’s BD desiccant dryers eliminate system failures, production downtime and costly repair and service works. 1000 0 660

THE RELIABLE CHOICE

Compressed air entering the air net is always 100% saturated. When cooling down, this moisture will condense, causing damage to your air system and to your finished products. Atlas Copco BD desiccant dryers eliminate the moisture completely before it can cause any damage. The BD dryers ensure a reliable process and impeccable end products by offering absolutely dry air to your compressed air system, with a pressure dewpoint of -40°C or even -70°C. 330 Water to the air net per day (liter) Flow 3000 6360 10800l/s cfm m 3 Average reference conditions: /h2000 4240 72001000 2120 36000 Pressure: 7 bar(e) Relative humidity: 60 % Ambient temperature: 25°C

• Adsorption/drying phase: wet compressed air flows upward through the silicagel desiccant beads, where the moisture is adsorbed.• Reactivation phase: the blower takes in ambient air and blows it to the internal heaters. The heated air is then sent through the saturated desiccant, forcing the adsorbed moisture out.Left towerRight towerBoth towers• Two towers contain silicagel desiccant. While one adsorbs the moisture from the air, the other is reactivated. • After regeneration, the functions of both towers are switched.
