Energy savings of up to 90% with Atlas Copco CD+ desiccant air dryers
A desiccant air dryer uses desiccants to adsorb moisture from the compressed air to protect the end-user’s equipment and end product. Atlas Copco’s energy efficient CD+ desiccant air dryer series is designed to deliver a constant pressure dewpoint even at full load under the most stringent of conditions.
Available in two ranges, the CD 25+-145+ and CD 110+-300+ feature a simple design and working principle making these compact desiccant air dryers ideal for a wide range of industries such as electronics, food & beverage, pharmaceutical and oil & gas where absolute dry air is critical.
The CD+ series boasts a small carbon footprint by minimising pressure drops and optimising the regeneration cycle to reduce energy consumption. “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,” explains Atlas Copco Compressor Technique Business Line Manager – Industrial Air Division, Wayne Jacobs. “Thanks to the Dewpoint Dependent Switching, dryer cycles are delayed, resulting in energy savings up to 90% compared to more traditional switching systems.”
The Elektronikon® controller monitors all parameters of the desiccant air dryers to guarantee a constant pressure dewpoint down to -70°C, even at 100% load. “This ensures absolute dry air for high-stake applications that require the highest reliability 24/7,” notes Jacobs. The Elektronikon® controller is equipped with a user friendly interface and navigation system. In addition, online visualisation enables remote monitoring, allowing for anticipation of operating and maintenance needs.
The robust vessels and galvanised piping with flanged connections of the CD 110+-300+ range ensures efficient regeneration while minimising leakages and keeping pressure drops low.
Thanks to easily accessible internal components and the use of durable materials such as butterfly valves, installation and service are quick and easy, extending maintenance intervals and keeping production downtime to an absolute minimum.
