FD range of refrigerant dryers from Atlas Copco Compressors

With throughputs ranging from 5-4000l/s (12-8480 cfm), the FD dryers are capable of removing damaging moisture from compressed air even in extremely hot ambient conditions, thanks to a highly durable refrigerant circuit, and thus eliminate the risk of system failures, production downtime and costly repair and service work.

Powerful and reliable, the FD’s cutting-edge performance is based on a reliable expansion device, hot gas by-pass, and a unique heat exchanger with contra flow on both air-to-refrigerant and air-to-air side. A built-in low velocity water separator and optimised airflow assures low pressure drop, reducing the energy consumption of the compressor, while condensate is effectively evacuated from the separation chamber via a no-loss condensation drain.

Maximum energy savings can be achieved through Variable Speed Drive (VSD) or the FD’s Saver Cycle Control that adjusts the working cycle to actual load. At the same time, the relative humidity of the compressed air at the dryer outlet is kept below 50% even when cycling.

VSD versions exactly match the water load to the dryer. As the load decreases, so does the speed of the compressor and the energy consumption of the FD dryer, resulting in savings of more than 50%.

With its small footprint, integrated state-of-the-art design and complete monitoring capabilities, the FD dryers provide exceptional benefits and meet the most stringent operational requirements.
