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.

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.

Customer success stories
Raw material savings with refining rebuild
JSC Arkhangelsk PPM, the biggest containerboard manufacturer in Russia, has recently invested significantly as they strive to increase capacity, product quality, cost efficiency and sustainability. OptiFiner Pro refiners helped the Novodvinsk mill to meet its targets with an upgraded stock preparation system.
Breast roll shaker improves paper quality and refiner rebuild gives energy savings in Hankuk Paper
Onsan mill removes product quality limitations with Valmet's solutions and saves EUR 50,000 in annual energy costs.
Refining rebuild at Savon Sellu
“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
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%.
