For high quality, dry air downstream from your oil-free compressor, Atlas Copco’s ND rotary drum dryers meet your needs perfectly. Providing energy-efficient drying by using heat of compression, they are the perfect solution for applications requiring pressure dew points as low as -45°C/-49°F. You benefit from a reliable process, impeccable end products, and the lowest total cost of ownership. What’s more, they offer outstanding energy efficiency. Compared to other desiccant dryers that can consume up to 15% of the compressed air, the ND dryer guarantees 100% flow capacity at the output.

Customer benefits



  • High efficiency – ND dryers are characterized by no loss of compressed air, zero purge by design, low pressure drop and no filtration requirements, all of which contribute to 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 – ND 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 ND dryers means they take up minimal space in your facility.
