L&W Freeness Online

Better optimize control and refining with more frequent and reliable freeness measurement


Paper makers have limited information from infrequent manual samples to try and optimize refining.

L&W Freeness Online delivers a fast sampling rate for Canadian Standard Freeness (CSF) or Schopper-Riegler (SR, MSR) measurements, providing more detailed and frequent information than manual sampling. With an accurate and comprehensive assessment of freeness in real time, mills can close the control loop, create uniform pulp furnish and lower energy consumption by eliminating over refining.

As a small footprint solution that is both easy to use and maintain with few moving parts, ABB offers exeptional reliability making this one of the lower total cost of ownership options with the highest accuracy and availability.
