Services for the entire lifecycle of your equipment
- Significant decrease in energy consumption – Valmet’s refiner segments enable up to 50% decrease in energy consumption. Valmet Gap optimizer and control upgrades have been documented to reduce refining energy consumption by 20%. Up to 4-5 t/h savings in fresh steam per hour with Valmet Steam separator C
- Zero unplanned shutdowns – preventive inspections and audits, and remote monitoring identifying issues before failure. Valmet refiner control systems efficiently prevents disc clashes and associated downtime
- Up to +100% refiner segment lifetime – Valmet refiner control reduces maintenance costs due to longer refiner segment and bearing lifetime through automatically optimized hydraulic pressure.
- 50% shive reduction – Refiner control systems enable stable operations with narrow disc gap.
- Increased outlet consistency by +2%, increased inlet consistency by 9% - Increased washing efficiency and reduced downtime through wash press upgrades. (ProFlow and ProNip/NipControl), for CTMP
- Full predictability with lifecycle partnerships (service agreement) – Restore stability proactively; with a Valmet exchange agreement, you can avoid late‑cycle emergency swaps that increase risk and cost.
- Leading service expertise in Mechanical Pulping technology – Largest installed base of HC refiners, plug screws and wash presses. Capacity to service non-Valmet equipment.

The Valmet Defibrator/Refiner Inspection
The Valmet Defibrator/Refiner Inspection is the anchor of the lifecycle plan. It assesses mechanical condition and operating environment to uncover deviations, prioritize actions, and generate clear recommendations for upgrades and spare parts — helping prevent additional costs and unscheduled shutdowns.
Scope (a focused checklist)
- Rotor/stator alignment and vibration behavior
- Lubrication and hydraulic systemschecks
- Sealing water system performance
- Housing, rotor, and related mechanical parts
- Process and running conditions review
