CentriTune centrifuge control system
Decades of experience in one box

You are already benefitting from leading separation equipment by choosing an ANDRITZ SEPARATION machine for your process. As we are proud to fulfil your requirements and want to support you further with more services and technologies, we have developed CentriTune, a unique automation product line.

All our extensive operation, troubleshooting, and start-up experience are now combined in a tailored automation solution. The nucleus of the CentriTune is a modular, PLC-based control system that supports you in making best use of your ANDRITZ equipment.

The basic module, which is the CentriTune Core, can interact in different operating modes, bringing undeniable advantages to your process

Relative speed control allowing the operator to enter the speed set points directly. If the feed product concentration is stable, this is the preferred and most efficient control mode.
Torque control mode for constant dryness at cake discharge. The speed set point for the drives is calculated accordingly via a sophisticated control algorithm. In this mode, the machine reacts automatically to any change in the feed concentration and ensures constant product quality on the output side, thus stabilizing operation throughout a vast operating window.
Cleaning sequences preconfigured for best use and flexible to adapt to your plant and your product
Maintenance and manual operation mode
Alarms and support in troubleshooting
Customer benefits
