Take control of your decanter performance

Decanter centrifuge operation depends on the interaction between feed conditions, machine parameters, and downstream process requirements.

Changing feed conditions
Variations in feed concentration can affect separation performance and product quality.
Consistent product quality
Stable cake dryness requires precise and reliable control of key operating parameters.
Operational complexity
Machine settings, cleaning sequences, and connected auxiliaries need to work together reliably.
Availability and lifecycle
Outdated control technology or limited diagnostics can increase downtime and troubleshooting effort.
