Atlas Copco Desiccant Air Dryers

MDG Rotary Drum Absorption Dryers

Atlas Copco MGD series rotary dryers direct the full flow of incoming hot, wet compressed air through a heat exchanger and then through to a water-cooled chiller that drops its temperature. The full stream of air is then directed through the drying portion of the desiccant drum to create cool, dry compressed air.

A portion of the product air is then circulated back through the heat exchanger, where it’s heated by the hot, wet air. This heated dry air then flows through the saturated desiccant for regeneration before mixing back into the initial stream of cooled wet air.

Most of the MDG dryer’s components are constructed from stainless steel for corrosion resistance, reduced weight and overall improved endurance. These dryers maintain impressive performance with minimal required maintenance.

This system provides up to 450 l/s capacity with dew points of -40°C/F and lower.

Industrial Applications

Rotary drum desiccant dryers can be used with any compressed air system that uses oil-free screw or centrifugal compressors. These dryers provide exceptional efficiency with very little waste for industrial applications such as:

• Food and beverage processing.
• Power generation.
• Automotive manufacturing.
• Pharmaceuticals.
• Breweries.
• Pulp and paper production.

All Atlas Copco rotary drum dryers have received ISO 22000 certification for food and beverage production safety. Using our rotary dryers as part of your compressed air system makes it easier to receive your own ISO 22000 certification.

XD+ Series Heat of Compression Desiccant Dryers

XD+ series twin tower desiccant dryers operate by using the natural heat produced in the compression process to regenerate saturated desiccant media. Incoming hot air is divided and directed through each tower for simultaneous drying and regeneration, producing an uninterrupted flow of dry compressed air.

This process requires zero purge air and almost no energy from outside the system, producing the maximum amount of dry compressed air as efficiently as possible. For this reason, the XD+ air drying system is ideal for high-demand applications, constant use and use in critical processes.

Atlas Copco XD+ series dryers offer ultra-low internal pressure drops below 0.2 bar/2.9 psi to minimize energy consumption. They also have built-in water separators that reduce the desiccant load and extend the drying cycle for optimal performance.

XD+ dryers are controlled and monitored by Atlas Copco’s patented Elektronikon system. These controls feature a 3 1/2-inch high-definition color display with LED indicators and user-friendly operations available in 32 different languages. You can connect to your controller via Ethernet for internet-based monitoring and visualizations.

XD+ -G Model

XD+ -G model desiccant air dryers pair the heat of compression with an additional onboard heater to achieve constant pressure and greater control over the dew point. Regardless of ambient conditions, this system can achieve dew points of -40°C/-70°C or lower because the heater provides adjustments to the heat of the incoming air.

The stainless steel onboard heaters only generate heat when it’s required to reach a particular dew point, so your overall energy consumption remains limited for money-saving operational efficiency.

The XD+ -G heaters feature overheating protection and control from the Elektronikon monitoring system on each heater bundle for safety and optimized performance. These dryers are available in both single inlet and double inlet variations.

XD+ -S Model

-S model XD+ dryers rely solely on the heat of compression to regenerate desiccant beads. Since these dryers do not feature onboard heaters, their achievable dew points vary depending on ambient conditions. Generally, they are able to deliver dew points of -10°C to -20°C.

When combined with a high outlet temperature compressor, like an Atlas Copco ZR model, the XD+ -S dryer can reach dew points as low as -40°C.

XD+ -S model compressed air dryers are available in both single inlet and double inlet variations to meet any application’s needs.

Industrial Applications

XD+ series desiccant air dryers can be used as a part of any system with oil-free air compressors. These dryers consume only small amounts of energy to produce a large amount of dry compressed air, making them ideal for applications with large demands or critical processes.

Common applications for XD+ heat of compression desiccant dryers include:

• Medical and health services.
• Food and beverage processing.
• Pulp and paper production.
• Pharmaceuticals.

Atlas Copco XD+ series compressed air dryers have received ISO 22000 certification for food and beverage production safety. When you use these dryers as part of your compressed air system, it makes it easier to receive your own ISO 22000 certification for your production facility.
