Plant Optimiser
  • Identify operational improvements in real-time
  • Provide daily advice on plant settings
  • Predict incidents before they occur and recommend appropriate changes
  • Define your operating and financial targets and track progress in real-time
  • Historical and forecast plant performance for all key variables.
  • Recommended set points for the next 24 hours based on machine learning and deterministic modelling.
  • Optimum settings to achieve design goals.
  • Forecast deviations from operational and environmental goals.

Intuitive plant design and digital twin configuration.

Drag, drop and connect unit operations on a flowsheet, then configure each unit operation to tailor your concept design or begin with typical defaults preloaded into each operation. Configured plants can be matched with any user scenario & shared with other users in your organisation.

Create block flow diagrams
Model Scenarios and Feed Streams.

Model Scenarios and Feed Streams.

Create feed scenarios with up to 5 feed streams for use in any of your configured plants. Each stream can be manually entered or your water analysis can be intelligently uploaded directly from a CSV file and balanced by the ion of your choice.


Plant Designer cuts down our bid cycle time by helping us lock in a design earlier. We now issue our vendor requests sooner, increasing the margin on our design phase and reducing delivery times.


Unique automatic calibration function, simultaneously evaluating thousands of configuration scenarios to provide the most accurate calibrated model configuration for the target design.

Identify ongoing operational savings of greater than 20% within weeks of implementation

Reduce design times by up to 70%
