DryXtreme - NST Adsorption Air Dryers

Logo DryXtreme - NST Adsorption Air Dryers

Product description

The heat regenerated adsorption air dryers in the DryXtreme - NST range treat large volumes of compressed air as the air flow of treated air necessary for regeneration is minimal.
The dew point of- 40 °C allows accurate and efficient operation in many critical applications such as the chemical-pharmaceutical, food, electronic, automotive industries or in external, low temperature installations.
The NST dryers are made up from two painted carbon steel vessels, both filled with absorbent material (activated alumina). The compressed air is dried alternately by the 2 towers, which are regenerated through combination of the heat emitted by a heater inside each vessel and a minimum flow rate of dry air.


Activated alumina adsorbent material with high resistance to abrasion;
Large adsorbent bed: allows a lower flow speed and higher contact time for maximum performance;
Regeneration air counter-current flow: increases performance and the efficiency of the adsorbent bed;
Gradual repressurisation phase: prevents the fluidization of the bed and extends the service life of the adsorbent material;
Possibility of connection to ModBus networks via RS485 port
Easily accessible main components to facilitate maintenance interventions
Top quality components;
Maximum reliability.
