Atlas Copco FD Dryer Series

The Atlas Copco FD series of dryers can handle up to 6,000 CFM

Based on years of experience in the industry, Atlas Copco has chosen to incorporate direct expansion technology with cycling, non-cycling and Variable Speed variants in its range.

Protecting your reputation and production
Compressed air entering the air net is always 100% saturated. When it cools, this moisture will condense, causing damage to your air system and finished products. Removing moisture from compressed air with a dewpoint as low as +3°C/+37.4°F, Atlas Copco’s FD refrigerant dryers provide the clean, dry air you need to expand the life of your equipment and ensure the quality of your end product. In addition,
FD dryers comply with the most stringent environmental regulations.

Keeping your production up and running
Atlas Copco’s FD refrigerant dryers are designed in-house, tested using the most stringent methods (at ambient temperatures up to 50°C/122°F) and manufactured on a very advanced production line. Separate components undergo severe endurance tests while the unique design of the heat exchanger significantly improves the dryer lifetime. Advanced control functions ensure dry air at all conditions and prevent freezing at low loads. FD dryers meet or exceed the international standards for compressed air purity and are tested according to ISO 7183:2007.

Driving down energy costs
Atlas Copco’s refrigerant dryers incorporate a range of energy-saving features that will cut your carbon footprint and reduce costs. Incorporating unique heat exchanger technology and Saver Cycle Control, the FD ensures a low pressure drop of typically below
0.2 bar/2.9 psi and minimal energy consumption. The integrated Variable Speed Drive (VSD) technology offers extra energy savings by automatically tuning the energy input to the precise demand. All this ensures a low lifecycle cost.

Easy installation and long maintenance intervals
FD dryers have a small footprint thanks to an innovative all-in-one design. Delivered ready for use, installation is straightforward, minimizing costly production downtime. FD dryers come as all-in-one packages including an electronic no-loss drain, integrated OSD condensate treatment (optional) and spin-on DD/PD filters (optional). For easy installation against the wall, the in- and outlet connections on some models are positioned on top of the unit.

Assuring your peace of mind
Through continuous investment in our competent, committed and efficient service organization, Atlas Copco ensures superior customer value by maximizing productivity. With a presence in over 170 countries, we offer professional and timely service through interaction and involvement. Uptime is ensured by dedicated technicians and 24/7 availability.

Low environmental impact
Fully compliant with ISO 14001 standards and Montreal Protocol regulations, FD dryers use CFC-free refrigerants (R134a, R410A, R404A)
to prevent any damage to the earth’s ozone layer. FD dryers have an ozone depletion potential (ODP) of zero and are enclosed in a sound suppression canopy to reduce the noise levels, making FD dryers among the most environmentally friendly and quietest in their class.
