For high-quality, dry air downstream from your oil-free screw and centrifugal compressors, Atlas Copco’s MD rotary drum dryers meet your needs perfectly. Using heat of compression – which requires negligible energy input – they are the perfect solution for a wide range of applications requiring pressure dewpoints as low as -25°C/-13°F. MD dryers are also often selected for applications where refrigerated dryers are suitable (+3°C/37°F PDP) due to the significant energy savings they offer. You benefit from a reliable process, impeccable end products, and the lowest total cost of ownership. Compared to other desiccant dryers that can consume up to 15% of the compressed air, the MD dryer guarantees 100% flow capacity at the output.

Customer benefits

• Maximum energy savings – The energy consumption of MD dryers is negligible: only 0.12 kW (water cooled version). MD dryers are characterized by no loss of compressed air, zero purge by design, low pressure drop and no pre- and after-filtration requirements. These factors contribute to additional energy savings and increased efficiency. A Variable Speed Drive (VSD) dryer version is available to match VSD compressors.

• Low maintenance – The combination of an easy to service vessel, minimal maintenance downtime and long service intervals reduces your maintenance time and costs.

• Environmentally friendly – MD dryers are totally oil-free and use no Freon or CFCs, and a minimal amount of desiccant (only 5-10% of conventional adsorption dryers). 95% of all components can be recycled, and the units have very low noise levels.

• Small footprint – The small footprint of MD dryers means they take up minimal space in your facility.
