The rotary atomizer F1000 is the world’s largest rotary atomizer for spray drying operations. It is designed and developed based on GEA Niro proven and recognized technology. Within flue gas desulphurization, the development of the F1000 enables GEA Niro to design spray dryer absorbers large enough to handle the flue gas from a 450 MWe coal fired power plant in a single absorber unit.


  • Chemical industry and in the area of flue gas desulphurization of power stations
  • Heavy-duty chemical applications that require very high throughput

Features and benefits:

  • Epicyclic gear drive
