Redesigned dryer range boosts efficiency

21st February 2013


Efficiency, reliability and customer convenience are the key benefits of the redesigned Atlas Copco FD 5-95 dryer range. 

The main features are the saver cycle control and the patented counter flow heat exchanger with integrated water separator. 

Adding a dryer to your compressor configuration (the FD 5-95 is compatible with compressors up to 30 kW) protects your end product while extending the lifetime of your equipment as it removes moisture, aerosols and dirt particles from compressed air. This dryer range is used in a variety of applications and industries including packaging, workshops, assembly, textiles, woodworking, plastics production and moulding, automotive, construction materials manufacturing, printing, and oil and gas activities.

The FD 5-95 is now a fully cycling dryer because of the integrated saver cycle control; providing energy efficiency. This algorithm is based on relative humidity and controls the start and stop function of the dryer’s compressor. By adjusting the working cycle to the actual load, this feature has a major positive influence on energy consumption. 

Moreover, the R134a refrigerant delivers better performance while using less energy.  Compared with other dryers, it also has a very low CO2 output, thereby a low global warming potential.

The total design of the FD 5-95 offers also an indirect energy saving through low pressure drop.  This is mainly caused by the counter flow heat exchanger and the integrated water separator and results in a lower energy use of the compressor itself.

In order to protect both the production process and the quality of the end product, the dryer needs to be reliable in every situation, even when facing high ambient temperatures. 

The most innovative adaptation of the FD 5-95 is the patented counter flow heat exchanger with integrated water separator.  Maximising the use of cold energy makes this type of exchanger far more efficient than the cross flow heat exchanger or the tube in tube heat exchanger. 

On top of this, Atlas Copco succeeds in evacuating condensation (even at reduced flow) by integrating the water separator in the counter flow heat exchanger. As a result, the pressure dew point is controlled and thus the quality of the end product is protected. 

Finally, condensation is further removed by the zero-loss electronic drain.

All these features improve the reliability of the compressed air delivered by the exisiting compressor configuration when a FD 5-95 is added.

The redesigned FD dryer has also been equipped with the next generation Elektronikon. This electronic controller gathers all annunciations in one location for customer convenience: PDP, ambient temperature, relative humidity and alarms.  Other advantages are the automatic restart after power failure and remote alarm.

Secondly, the number of available models has been increased, making it easier to match the dryer to the FAD of an exisiting compressor; thus saving even more energy.  The standard maximum pressure has also been improved. The FD 60-95 can provide up to 13 bar while the FD 5-50 can go as high as 16 bar.  (The high pressure variant delivers 20 bar)
 
Finally, there have been several standard and optional adaptations to reduce the footprint of the FD 5-95 dryer. A smaller dryer eases the installation while maintenance is further aided by standard features like zero-loss electronic drain with easy cleaning (a timer drain for 20 bar units) and a click on front panel (other available options are integrated or spin-on filters, integrated condensate treatment, IP54 protection and wall mounting kit).
 
All the elements mentioned above, prove that the Atlas Copco FD dryer is built for reliability and will provide peace of mind; while keeping the ecological footprint as minimal as possible.
