SMD 2-55 Membrane Air Dryers

Atlas Copco SMD 2-55 membrane air dryers remove water and oil particles, reducing the risk of corrosion and preventing costly downtime. By delivering clean, dry air, they lower energy costs, minimize leaks, and protect the quality of your final products from moisture-related contamination.

Introducing the Atlas Copco SMD 2-55 Membrane Air Dryers

If you’re looking for effective, ow-maintenance air drying performance, the Atlas Copco SMD 2-55 membrane air dryers is your ideal solution. Thanks to its simple design, our membrane dryer is quiet, efficient and easy to operate. It has no moving components, which makes it 100% maintenance free. With its low pressure drop and purge air use, the Atlas Copco SMD 2-55 membrane air dryers provide real energy savings without compromising on drying effectiveness.

Advanced drying technology Compared to conventional membrane dryers, the SMD’s unique coating increases separation efficiency with a low air leakage and purge air loss to give you maximum energy efficiency. A choice of membranes SMD dryers come with two types of membranes, each offering a different pressure dew point suppression level. This ensures that regardless of your production environment and demands, there are Atlas Copco SMD 2-55 membrane air dryers to meet your needs. Low air resistance saves energy Due to the simple design of the SMD, the compressed air travels straight through the dryer – ensuring minimal pressure drop and maximum drying efficiency

Your choice of performance

SMD 3-32 up to SMD 35-32:
PDPS of 32˚C at reference conditions.

SMD 2-55 up to SMD 23-55:
PDPS of 55˚C at reference conditions.

The dryers come configured as standard with optimized purge nozzle for 3 pressure variants:

13 bar(e)/188 psig

Technical specifications

Notes:

For higher flows, please contact your Atlas Copco sales representative.
For lower ambient temperatures down to -20°C/-5°F, please contact your Atlas Copco sales representative.

Reference conditions:
Air inlet temperature: 35°C
Air ambient temperature: 25°C
Inlet relative humidity: 100%
Inlet pressure: variant dependent (7, 10 or 13 bar)

Operating limits:
Maximum compressed air inlet pressure: 13 bar(g)
Minimum compressed air inlet pressure: 4 bar(g)
Maximum ambient temperature: 60°C
Minimum ambient temperature: 1°C
Maximum compressed air inlet temperature: 60°C
Minimum compressed air inlet temperature: 1°C

• For pressures other than the ones mentioned above, correction factors give the correct flow
• Pressure dew point suppression of 15ºC (27ºF) to as much as 95ºC (171ºF) is possible. Correction factors give the correct flows
• The performance of the SMD membrane dryer range is independent ofambient temperature and inlet temperature, it is only dependent ofinlet dew point.
