Atlas Copco FD Cycling Refrigerated Air Dryer

Atlas Copco FD Refrigerated Air Dryer (FD 5–95 & FD VSD 100–300)

Protect your air system with an FD Dryer engineered for a stable +3 °C / +37.4 °F pressure dew point, low pressure drop, and day-in, day-out reliability. Tested to ISO 7183, the FD family delivers clean, dry compressed air with proven components and smart controls—no fluff, just uptime.

Why it matters: untreated air corrodes piping, damages pneumatics, and ruins product. The FD fixes that—efficiently.

Core performance (FD 5–95):

• Flow range: 6–95 l/s (13–201 cfm) across 11 sizes
• Dew point: as low as +3 °C / +37.4 °F for consistent quality
• Pressure drop: typically < 0.2 bar / 2.9 psi to cut indirect energy cost
• Heat exchanger: high-efficiency counter-flow (brazed plate or aluminum) with air-to-air precooler for low ΔP
• Condensate management: electronic no-loss drain with level sensor; opens only when needed
• Control: Elektronikon® Alpha—dew point & ambient temp display, relative humidity, energy-saving mode, high/low dew-point alarm, alarm history, remote visualization, and voltage-free remote start/stop
• Robust hardware: hot-gas bypass (no freezing at low load), low-noise compressor with integrated liquid separator, louvered-fin condenser for dusty sites, integrated water separator, single electrical connection (plug-and-play), compact footprint, quiet operation
• Refrigerants: R134a (FD 5–50) and R410A (FD 60–95); ODP = 0
• Operating limits: ambient 1–46 °C (34–115 °F); inlet 5–60 °C (41–140 °F); pressure 6–14 bar (87–203 psi) (FD 5–50 up to 16 bar / 232 psi)

Step up to FD VSD 100–300 (Variable Speed Drive):

• Flow range: 100–300 l/s (212–636 cfm)
• Energy: up to 70% direct and up to 50% indirect energy savings vs conventional dryers; ΔP typically < 0.2 bar; superior dew-point stability vs thermal-mass designs
• Drive & control: in-house VSD inverter matches compressor speed to demand; Elektronikon® Touch (4.3" color UI) with visualization, alarm history, auto-restart, week schedules, and built-in SMARTLINK remote monitoring
• Refrigerant: R410A, ODP = 0, excellent TEWI profile
• Build: integrated water separator, high-efficiency counter-flow heat exchangers, hot-gas bypass, forklift openings, front/side service access, compact “all-in-one” design; delivered ready for use; quiet

What you actually get:

• Clean, dry air that protects tools, valves, and end product
• Lower total lifecycle cost through minimized pressure drop and intelligent control
• Compliance & consistency: ISO 7183 testing; constant purity class per ISO 8573-1 with a stable PDP
• Real durability for harsh, dusty environments

Note: Specs and limits vary by model; select the FD or FD VSD size that matches your flow, temperature, and pressure requirements.
