Sludge Regulator

Connecting the Noxon sludge regulator to the decanter centrifuge makes unmanned dewatering possible around the clock. The sludge regulator controls, regulates, registers and monitors the process during operation. Alarm functions stop and flush the centrifuge clean if anything unexpected occurs.


Operator-friendly process with complete control
Noxon’s SP400 Sludge Regulator is an advanced industrial computer which has been specially adapted for sludge dewatering with customized software for Noxon’s centrifuges. A large operator-friendly screen makes it easy for the operator to monitor the process. The screen shows a graphic representation of operational events, while statistics and trend curves can be easily accessed for analysis. This gives our customers complete control of their sludge dewatering process, resulting in drier sludge and reduced processing costs.


SP4000 is microprocessor-based control and regulation equipment with an integrated operator panel. The sludge regulator starts, stops, regulates and monitors the entire dewatering process with optimum functionality.

The following processes can be managed by the SP4000

  • Control
  • Regulation
  • Registration
  • Monitoring

The sludge regulator’s large screen provides a comprehensive visual display of the process. The screen shows a continuously updated graphic representation of the process. The SP4000 touchscreen is simple to operate – additional information is easily accessed by pressing the desired function on screen. Operational statistics and trend curves are shown directly on screen for daily or weekly analysis.

The regulator is equipped with a modem for support, troubleshooting and updating, and can also be connected to a local area network via the Internet.

SP4000 can also communicate with parent systems. Communication is also available via Modbus ASCII + RTU or COMLI. Using a converter, communication is also available via Profibus DP.

SP4000 displays on-screen messages when maintenance needs to be carried out, depending on operating times.
