Valmet offers roll upgrades with runAce

Valmet says its RunAce upgrade services provide improved roll performance and productivity by applying innovations to a mill’s existing roll base. Modular maintenance solutions such as RunAce upgrade services are especially targeted for critical process rolls such as deflection-compensated rolls and suction rolls.

Upgrading an existing roll base offers several benefits, says Valmet, including improved machine runnability, machine efficiency and extended machine time; also, energy efficiency and safety can be improved. There is a range of suction roll innovations for added reliability, performance and energy efficiency.

One example of RunAce upgrades for suction rolls is the SealFlo axial seal lubrication shower which Valmet says offers uniform seal lubrication, reduced water consumption and extended seal life. Other RunAce services include:

• LocSeal: reduced power consumption; longer axial seal and shell lifetime.

• ShellFlo H: cleaner shell through holes; maximum dewatering capacity; improved CD moisture profiles.

• EdgeBlow: fewer breaks; improved machine efficiency; cleaner shell edge areas.

• EdgeLight: fast, easy vacuum zone (CD & MD) positioning; improved energy efficiency; maximized dewatering.
