Atlas Copco Refrigerant Air Dryers FD series (6-4000 l/s, 13-8480 cfm)
Why dry your compressed air? Compressed air is used in a wide variety of industrial applications. Wherever it is used, compressed air must be clean and dry. Containing solid, liquid and gaseous contaminants, untreated compressed air poses a substantial risk as it can damage your air system and end product. Moisture, one of the main components of untreated air can cause corrosion in pipe work, premature failure of pneumatic equipment, product spoilage and more.
What is a refrigerant dryer? A refrigerant dryer uses a refrigerant circuit and heat exchanger(s) to pre-cool air, refrigerate it to condense out moisture vapor, and then re-heat the air to prevent pipe sweating downstream. Refrigerant dryers can lead to a pressure dewpoint (PDP) as low as +3°C/+37.4°F for many applications where there is a need for dry air. They can be used at different pressures and consume no processed compressed air.
Atlas Copco’s FD refrigerant dryers 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. Direct expansion dryers without Saver Cycle Control (non-cycling) FLOW Applications: stable dewpoint, full load applications. Key advantage: fixed speed dryers run continuously to ensure a stable dewpoint by design (irrespective of varying load conditions). Range: FD 5-2000.
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.
FD 5-95 & FD 120-285: Superior productivity 1 Level sensor senses the level of the condensate and opens the drain, preventing any loss of compressed air when condensate is drained. Equipped with backup manual drain as standard and drain alarm (FD 120-285). 2 Electronic no-loss condensate drain High-efficiency heat exchanger Counter-flow compact brazed plate (FD 5-50) or aluminum (FD 60-285) heat exchanger, with air-to-air side for optimum cooling efficiency.
6 Optimum performance and safety in all conditions Hot gas bypass valve prevents freezing at lower loads. R134a piston compressor with high coefficient of performance (FD 5-95) or extremely reliable R410A rotary compressor (FD 120-285) provide the best performance for each size while having minimum environmental impact. Capillary tubes cope with all conditions – no moving parts for extra reliability.
FD 310-4000: Superior productivity 1 Counter-flow on both air-to-air and air-to-refrigerant sides for efficient heat transfer. As the outgoing air is reheated, it protects the outlet piping against pipe sweating. Unlike some other dryer designs, a separate pre-filter is not required. This results in a low pressure drop. The design ensures a smooth air flow which makes the dryer less sensitive to contamination.
User-friendly state-of-the-art Elektronikon® controller Monitoring of all parameters to ensure maximum reliability for your installation. Fitted inside a real IP54 cubicle for easy cabling and safety. * The type of controller may vary depending on the model. 6 For processes requiring higher levels of filtration, Atlas Copco offers integrated DD and PD filters (optional on FD 310-510). 5 4 Filters Hot gas bypass valve Prevents freezing at lower loads.
Supreme energy efficiency When purchasing a refrigerant dryer, the main focus is usually on the initial cost. What is mostly overseen is that this only represents approximately 10% of the lifecycle cost, the rest being taken up by energy, maintenance and installations costs. Of these, direct and indirect energy costs (pressure drop) are the most important.
Direct energy costs Direct energy costs are related to the power that the dryer consumes. Atlas Copco's FD dryers incorporate a variety of state-of-the-art technologies such as Saver Cycle Control and Variable Speed Drive. These features result in further savings on energy costs, depending on your air consumption profile.
A step ahead in control and monitoring Atlas Copco's Elektronikon® controls and monitors your FD refrigerant dryers to ensure optimal productivity and efficiency at your site. User-friendly interface Available in 32 languages, this graphical 3.5-inch high-definition color display with pictograms and LED indicators for key events is easy to use. The keyboard is durable to resist tough treatment in demanding environments.
