L&W FeltScan Moisture

Press felts must be cleaned and conditioned to enable the felt to take water and be de-watered uni-formly throughout its lifetime. Having accurate measurement of felt status is therefore imperative for not only a cost-effective and efficient felt conditioning program, but also for maximizing machine run-nability— and profitability.

L&W FeltScan Moisture provides paper mills, felt and chemical suppliers with industry-standard results for felt moisture measurement. By detecting press felt compacting, crowning, clogging, and wear as well as the effectiveness of your felt conditioning, suppliers can provide more precise recommendations and paper mills can extend and optimize performance.
