  • Decanters operate efficiently and continuously
  • Decanters can be tuned to the optimum performance according to the feed
  • Decanters are compact in themselves, they do not need much peripheral equipment
  • A decanter is a closed system. There are no splashing or odors
  • Extra erosion protection is added at sensitive spots


Direct Drive is a unique system developed by Alfa Laval for automatic control of the differential speed between the bowl and the conveyor. Direct Drive comprises a new type of gearbox and variable frequency drive, which do not expose the bowl drive to parasitic braking power loss. The electrical installation is straightforward, power consumption is kept to a minimum and accurate control is achieved within a wide range of differentials.
Or the decanter is controlled by a dedicated control system with a central processor, featuring a graphic interface. The system controls the Direct Drive, dependent on the solids load in the bowl.
