Atlas Copco's desiccant air dryer ranges feature low pressure drops, delayed dryer cycles and a constant pressure dew point
Atlas Copco's desiccant air dryer ranges are designed for efficiency with low pressure drops, delayed dryer cycles and a constant pressure dew point — even at full load. Atlas Copco offers two ranges of heatless desiccant dryers, the CD 25+-145+ and the CD 110+-300+, and a range of blower purge dryers, the BD 100+-300+.
The CD+-BD+ series is designed to reduce energy consumption and lower the carbon footprint by minimizing pressure drops and optimizing the regeneration cycle. The CD+-BD+ series contains a pressure dew point sensor that is engineered to measure the remaining humidity in the compressed air, detect when the active tower is completely saturated and then switch the functions of the two dryer towers at the optimal moment.
The CD+ dryer range uses a portion of the dried air to regenerate its towers, whereas the BD+ range mainly uses ambient air to dry its desiccant. Since the CD+ does not use ambient air, it is also suitable for hazardous environments. The BD+ blower purge technology is engineered to permit downsizing of both the BD+ desiccant dryer and the compressor compared to a similar installation with the CD+ range. The vessels and piping with flanged connections of the CD 110+-300+ and BD 100+-300+ are designed for efficient regeneration while minimizing leaks and keeping pressure drops low.
