Air washers

SCRUBVAP®

The circulating water spray humidifier, also called an air washer, is the classic among humidifier systems. The water quantity atomised within the airflow is several times greater than the water flow required for humidification. The water that is not evaporated is captured in a tank and channelled back to the nozzles.

Application areas for circulating water spray humidifiers

  • High increase in humidity (1.0 to 10g/kg and more)
  • From small to large volumes of air (1,000 to 2,000,000 m³/h)
  • Air purification (wash-out effect!)
  • Operation by means of municipal water
  • Low-maintenance spray nozzles through large flow cross-sections
  • Low-maintenance pump

Equipment variants:

  • Automatic level control
  • Automatic draining with hygienic flushing
  • Automatic elutriation
  • Physical sterilisation (UV immersion lamps, UV reactor)
  • Chemical sterilisation (hydrogen peroxide, chlorine dioxide)
