DONALDSON Boreas Refrigeration Compressed Air Dryers with Variopulse.
The proprietary design of Boreas heat exchangers, incorporates large flow channels for low pressure drop, which translates into low operating costs. A built-in cyclone separator with our Ultramat® zero-loss drain valve allows, removal of condensed water without wasting any compressed air. The space-saving design brings cooling air in the front and out the top, allowing the unit to be placed next to a wall with other equipment on either side. All Boreas dryers utilise environmentally friendly R-134a refrigerant and are available in either air- cooled or water-cooled configurations. Volume flows of 1.800 to 28.500 m³/h are covered by the Boreas series.
