FD series
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.
Saver Cycle Control
To help you save energy, Atlas Copco FD dryers are able to adapt their working cycle to the real load by continuously monitoring and
comparing the ambient temperature and the pressure dewpoint. When there is less heat load, the refrigerant compressor stops and
power consumption is significantly reduced.
Variable Speed Drive (VSD)
The VSD controller incorporated in certain FD refrigerant dryers matches the energy consumed to the actual compressed air used.
This significantly reduces energy consumption – by as much as 70% compared to conventional dryers. It works by varying the
speed of the compressor and ensuring a stable dewpoint. In this way the speed of the refrigeration compressor can be matched to
inlet conditions, resulting in lower energy consumption at reduced loads.
Flow switch
If the compressor is unloaded for some time, the flow switch shuts down the refrigerant compressor automatically, typically after
ten minutes, saving energy.
