Atlas Copco FD Series Refrigerated Dryers
Atlas Copco’s FD Refrigerant Air Dryers remove moisture from compressed air before it enters the air network, preventing costly damage to air tools, instruments, mechanisms and piping.

First-Rate Efficiency
- Available in 11 sizes from 6 to 95 l/s/13 to 201 cfm.
- Pressure dew point as low as +3°C/+37.4°F.
- Electronic no loss drain with safety function.
- Controller with pressure dew point display, energy saving option, alarm contacts
- Quiet operation.
- Constant purity class -;4 – according ISO 8573-1:2010.
-
Low-noise compressor with liquid separator – Lasts longer thanks to limited vibrations, minimal moving parts, and reduced risk of leakage.
-
High-efficiency heat exchanger – Counter-flow compact brazed plate or aluminum heat exchanger, with air-to-air side for optimum cooling efficiency and the lowest possible pressure drop.
-
Integrated water separator – Low velocity with high separation efficiency even in low flow conditions.
-
Electronic no-loss condensate drain – With level sensor, backup manual drain and drain alarm.
-
Fan switch – Reduces energy consumption and optimizes the pressure dew point at very low temperatures.
-
Hot gas bypass valve – Ensures stable pressure dew point and prevents freezing at lower loads.
-
Refrigerant separator – Eliminates the chance of moisture entering the compressed air system.
-
Single electrical connection – Allows for plug-and-play installation.
Supreme energy efficiency
- The FD offers a low pressure drop – typically below 0.2 bar/2.9 psi – and minimal energy consumption.
- The compact brazed plate or aluminum heat exchanger was designed specifically to provide optimal pre-cooling and the lowest possible pressure drop.
- The electronic no-loss condensate drain comes with a level sensor to open the drain only when needed, preventing unnecessary loss of compressed air.
Comprehensive control and monitoring options
- The Elektronikon® Alpha controller displays the pressure dew point and relative humidity.
- Remote alarm and start/stop control through voltage-free contact.
- Additional features such as alarm history and standard remote visualization.
Easy installation and long maintenance intervals
- Small footprint thanks to an innovative all-in-one design.
- Delivered ready for use, minimizing costly production downtime.
Low environmental impact
- FD dryers use CFC-free refrigerants (R134A and R410A) with an ozone depletion potential (ODP) of zero.
Reliable performance in tough conditions
- Hot gas bypass valve prevents freezing at lower loads.
- R134A piston compressor with high coefficient of performance (extremely reliable R410A rotary compressor for models FD 60-FD 95) provides the best performance with minimum environmental impact. Capillary tubes cope with all conditions – no moving parts for extra reliability.
- Condenser with louvered fin technology for improved performance in dusty environments.
Based on direct expansion technology, our high quality FD refrigerated air dryers remove moisture from compressed air with a stable dew point as low as +3°C/+37.4°F. Water- and air-cooled versions are available. The introduction of Atlas Copco’s VSD (and later VSD+) compressor technology was an industry milestone. With the FD VSD, we are extending this energy-saving principle to your quality air equipment as well.
