ATB-HSA – Direct Drive Floating Surface Aerators

ATB-HSA aerators create an extremely flat and almost horizontal spray 360° around the unit. The feasibility range covers lagoon installations as well as activated sludge plants, SBR and MBR systems.

Your advantages

  • Air-cooled motor: no submerged sealing = extended lifetime
  • Direct drive: no gearbox = low maintenance
  • Wide range: available from 0.75 kW to 55 kW
  • High turbulence: good mixing and high alpha factor
  • Horizontal spray: low aerosols
  • Installation: floating = fast and simple
  • Materials: stainless steel AISI 304 or 316

ATB-HSA-HSM – Combined Surface Aerator / Mixers

ATB-HSA-HSM combined aerator / mixers are the easiest and most cost-effective way to perform autonomous aeration and mixing in a tank with a single device. The flows of both parts of the unit complement each other perfectly so that they can work in single motor operation mode or together.

Your advantages

  • Deep tanks: the support of the downdraft mixer allows the use of the surface aerator also at very high water levels
  • Combined aerator-mixer: double-action unit for nitrification / denitrification or SBR
  • Direct drive: no gearbox = low maintenance
  • Air-cooled aerator motor: no submerged sealing
  • Wide range: available from 0.75 kW to 55 kW (aerator) / 15 kW (mixer)
