Valmet’s OptiRun dryer section portfolio is able to provide perfect solutions for all customer needs. OptiRun dryer sections use proven technology and have a great number of references, including many of the world’s fastest machines.
Excellent runnability and productivity
Uniform quality and profiles
Low life-cycle cost
The OptiRun dryer section family consists of four solutions that cover all dryer geometries, providing optimal drying capacity and excellent runnability. Each dryer section features UnoRolls, VacRolls and/or Edge VacRolls, depending on machine speed and paper/board grade, in order to ensure smooth tail threading, runnability and energy efficiency. OptiRun dryer sections are available with both steel and cast iron dryer cylinders.
Optimal geometry ensures total web support throughout the dryer section. Support after the press and efficient runnability components produce a high strain potential, low porosity, and improved internal strength. In addition to conventional geometry, these dryers are also available with a compact geometry. The benefits include energy savings thanks to using fewer fans, improved drying capacity due to the large cylinder wrap angle, and minimal sealing wear against roll/fabric due to minor fabric bending.
