Ultra-Low Dew Point Clean Air Supply System: CDASS-100


● Supplies ultra-low dew point air using dehumidification rotors in three stages in series.

● Supplies clean and dry air (CDA) with dust and inorganic gaseous pollutants containing organic and NOx removed at a dew point temperature of -100℃ (8.7 wt ppb) or less.

● Production and supply of CDA at low cost using dehumidification rotor.

● The running cost is 1/5 to 1/10 compared with compressed air (pressure swing type). There is no worry of asphyxiation unlike nitrogen gas systems. Supplies a large volume of CDA at 15-30 m3/min at atmospheric pressure.
