Low-noise compressor with liquid separator
Lasts longer thanks to limited vibrations, minimal moving parts, and reduced risk of leakage.

Integrated water separator
Low velocity with high separation efficiency even in low flow conditions.

Fan switch
Reduces energy consumption and optimizes the pressure dew point at very low temperatures.

Refrigerant separator
Eliminates the chance of moisture entering the compressed air system.

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.

Electronic no-loss condensate drain
With level sensor, backup manual drain and drain alarm.

Hot gas bypass valve
Ensures stable pressure dew point and prevents freezing at lower loads.

Single electrical connection
Allows for plug-and-play installation.

First-Rate Efficiency

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.

Easy installation and long maintenance intervals

• Small footprint thanks to an innovative all-in-one design.
• Delivered ready for use, minimizing costly production downtime.

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.

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.

Low environmental impact

• FD dryers use CFC-free refrigerants (R134A and R410A) with an ozone depletion potential (ODP) of zero.

Advanced control

Atlas Copco’s refrigerant dryers are built to reliably and efficiently deliver quality air. But in the end, it’s all about how they perform on your work floor, meeting your individual needs and responding to your specific conditions. That is why the FD VSD, FD and FX come with comprehensive control options to allow you to get the best performance from your Atlas Copco dryer.
