Better optimize control and refining with more frequent and reliable measurement.
Mills have limited information from infrequent manual samples to try and optimize refining.
L&W Freeness and Fiber Online provides accurate and continuous fiber morphology measurements for the wet end. This enables closed loop control and uniform pulp furnish for better runnability on paper, board or tissue machines, helping make more on spec product at less cost.
As a single unit that is both easy to use and maintain, paper makers benefit from the combined and more frequent online measurement of both freeness and fiber properties, giving the full picture of dewatering status and fiber quality in real time to take immediate action. ABB offers exceptional reliability making this one of the lower total cost of ownership options with the highest accuracy and availability.
Measurement according to standards
L&W Freeness and Fiber Online measures Canadian Standard Freeness (CSF) or Schopper-Riegler (SR or MSR), which relates to TAPPI (T-227) and ISO (5267-1 and 5267-2) standards. Fiber properties are measured according to international standards (ISO 16065-2); it is based on ABB’s well-known L&W Fiber Tester Plus.
