OptiFiner Pro refiner

One is enough

OptiFiner Pro is a revolutionary new refining concept, in which one refiner can replace two traditional refiners and even deliver 30% electrical energy savings. OptiFiner Pro refiners are suitable for all kinds of low consistency refining applications.

Significantly smaller investment cost

High energy efficiency saves in operation costs and supports sustainable development. The reduced number of refiners in the system also reduces maintenance cost, leading to lower entire life cycle cost and less environmental stress.

Unique flow-through technology

The stock is spread evenly across the bars where fiber treatment occurs and later, after the fiber treatment, exits straight out from the refiner. The design ensures that all the stock is treated evenly, providing higher refiner loadability and better energy efficiency.

Exceptional efficiency

OptiFiner Pro enables a remarkably higher installed power and throughput. The refiner’s hydraulic capacity is not sensitive to fillings wear. It’s pumping curve is also lower and more even than with conventional refiners.

Quick and precise power control

Gap control is made by a moving rotor with a new generation loading system comprising of a servo motor and its control.

  • One OptiFiner Pro can replace two traditional refiners and deliver 30% electrical energy savings
  • It reduces no-load power 50%
  • All the stock is treated evenly, providing higher refiner loadability and better energy efficiency
  • Significantly smaller investment cost
  • Suitable for all kinds of low consistency refining applications

Get hard facts to support investment decision

Valmet has the experts and the Paper Technology Center in Finland where mill scale laboratory trials can be compared with your actual production conditions in order to justify the investment. Trials can be made with industrial scale refiners and besides standard laboratory tests such as tear and tensile measurements, the laboratory can also perform evaluation of fiber morphology through microscopic analysis.

“We believe that the unique refining principle of the OptiFiner Pro gives us an advantage. As a bonus, we use 30% less energy while achieving the same freeness values as before", tells Tapio Laukkanen about the results of a refining rebuild at Savon Sellu.

Improved end product quality with right refining

Improved end product quality with right refining

The first OptiFiner Pro refiner in Southern Europe started up in Cartiere Ermolli mill in 2014. The new refiner replaced two existing refiners at PM 1, increased the overall refining capacity significantly and reduced energy consumption by 20%.
