Atlas Copco launches 3 new desiccant air dryer ranges. These were designed for efficiency with low pressure drops and delayed dryer cycles. Additionally, high performance and a constant pressure dewpoint -even at full load- are guaranteed under any condition.
The new products include 2 ranges of heatless desiccant dryers, the CD 25+-145+ and the CD 110+-300+. The simple design and working principle guarantee reliability of these compact desiccant air dryers, even in harsh conditions.
The third new range is the blower purge dryer BD 100+-300+; built for energy-efficiency and endurance.
By using heated ambient air for regeneration, this dryer range keeps the energy cost minimal.
A desiccant air dryer protects your production, equipment and the quality of the end product by using desiccants to adsorb moisture from the compressed air.
These 3 new desiccant air dryer ranges are suitable for the most demanding industries and applications like electronics, food and beverage, animal feed, pharmaceuticals, oil and gas, etc.
The new CD+-BD+ series are kind to your energy consumption and carbon footprint by minimizing pressure drops* and optimizing the regeneration cycle.
The pressure dewpoint sensor measures the remaining humidity in the compressed air, detects when the active tower is completely saturated and then switches the functions of the two dryer towers at the optimal moment.
Thanks to the Dewpoint Dependent Switching dryer cycles are delayed, resulting in energy savings up to 90% compared to more traditional switching systems.
The CD+ dryers use some of the dried air to regenerate its towers, whereas the BD+ mainly uses ambient air to dry its desiccant.
Since the CD+ does not use ambient air, it is also suitable for hazardous conditions.
On the other hand, the BD+ blower purge technology allows to downsize both the BD+ desiccant dryer and the compressor compared to a similar installation with the CD+ range; resulting in major energy savings.
* The pressure drop of the CD 110+-300+ and BD 100+-300+ ranges drop below 0.2 bar (e)/2.90psig.
** Pressure dewpoint (PDP) refers to the water content in compressed air. It is the temperature at which water vapor condenses into water at the current working pressure. Low PDP values indicate small amounts of water vapor in the compressed air.
