Compressed air is commonly used for power tools and equipment in production and finishing processes or to activate valves and instruments. The compression process itself causes the concentration of moisture, of the lubricant oil vapours and the particles of impurities present in the air sucked from the compressor, up to levels that can damage the pneumatic equipment, increase the need for maintenance or ruin the finished product.

The DN dryers are suitable for the treatment of high flow rates of compressed air and offer two important advantages: extremely high energy savings, with the possibility of using up to 4 compressors offering load dependent partialisation; maximum operating safety, thanks to the installation of several compressors in independent refrigeration circuits.
All DN models are equipped with high efficiency scroll compressors and are fitted with the innovative DRYSTREAM exchanger able to guarantee extremely low dew points in all conditions as well as reducing pressure drops to a minimum along with energy consumption.

  • Exceptional reliability: The presence of 4 compressors within 2 separate refrigeration circuits (DN300 – 380) guarantees 50% of its capacity even in the unlikely event of a fault on one of the two circuits
  • Loss of nominal pressure lower than 0.2 bar
  • Demister pre-filter, standard on all models
  • Phase monitor and standard compressors crankcase heaters
  • Constant dew point in all conditions
  • Condensate separation independent from air flow rate
  • Low environmental impact and reduced carbon dioxide emissions thanks to the use of environmentally friendly refrigerant R407C and the use of top quality materials that can be recycled.
  • Simplified maintenance
  • DRYSTREAM heat exchanger with copper pipes and aluminium fins, compact and high efficiency
  • Environmentally friendly refrigerant R407C
  • High energy efficiency hermetic scroll compressors
  • Finned coil condensers with copper pipes and large aluminium fins (DN225/A)
  • Shell and tube condensers for well/tower water (DN225/W-DN300/W-DN380/W)
  • Pressostatic valves for condensation control (DN225/W-DN300/W-DN380/W)
  • Axial fans(DN225/A)
  • Thermostatic throttle valves
  • Hot gas by-pass valves
  • Microprocessor controller PCO, with many parameters and alarms that can control the compressors and the condensate drain
  • Chronology of the alarms with memorisation of the last 50 events
  • General alarm free contact
  • Remote ON/OFF clean contact
  • Standard zero-loss capacitive condensate drain
  • Standard phase monitor: guarantees protection from missing phase and incorrect sequence of phases
