A new monitoring application to secure bearing lubrication in fiber processing equipment


Valmet launches a new application, Valmet Oil Monitoring, to remotely monitor oil lubrication in fiber processing equipment.

As various rotating machinery throughout the fiberline perform under extremely harsh and demanding environments, it is often difficult to manually retrieve oil samples. Maintaining an adequate surveillance of lubrication properties against harmful effects can prove very challenging.

“Valmet’s oil monitoring system provides constant remote lube oil condition monitoring visibility through its novel sensoring and data acquisition technology,” says Heikki Kettunen, Senior Manager, R&D, Rolls and Workshop Services, Valmet.

The damages in rotating equipment bearing are mostly related to insufficient bearing lubrication. Typical failure modes such as bearing vibration and elevated temperature are normally only observed when the failure has already progressed. With Valmet Oil Monitoring, upcoming failures can be foreseen through changes in lubrication oil quality. The solution enables corrective actions before the actual failure arises, reducing unplanned shutdowns and the need for subsequent repairs.


First application in pulp washing machinery

The Valmet Oil Monitoring application was first installed to follow roll bearings’ oil lubrication in a TwinRoll wash press in a European pulp mill. The application detected contamination in the bearing oil circulation unit. This observation was flagged, and the machine operators were able to react quickly with corresponding maintenance actions.

Valmet Oil Monitoring, together with the specific applications for chip feeders in continuous cooking and TwinRoll presses in pulp washing, form the offering of Valmet’s modular reliability monitoring platform. The platform is intended for fiber processing equipment and was introduced in 2022.

Valmet’s reliability monitoring applications are part of the Valmet Industrial Internet offering and provide powerful tools for fiber producers to secure equipment availability and improve process performance.

Valmet Oil Monitoring system can forecast deterioration before the first signs of bearing failure and, thus, improves process reliability.


Compostable label face papers for fruit and vegetable stickers

UPM Specialty Papers ( now offers a compostable solution for paper-based food stickers. UPM LabelCoatTM and UPM LabelCoatTM Prime label face papers are certified as both industrially (EN13432:2000) and home compostable (NFT51-800:2015), helping customers and brand owners meet EU’s Packaging and Packaging Waste Regulation proposal (PPWR) requirements.

PPWR aims to ensure that all packaging in the EU must be reusable or recyclable by 2030. It also sets out the requirements that sticky labels attached to fruits and vegetables need to be compostable in industrially controlled conditions.

“We are happy to provide a compostable solution, which helps our customers to meet this regulatory change as well as their sustainability targets,” says Juhani Ylikoski, Sales Director at UPM Specialty Papers.

In addition to fruit stickers, UPM LabelCoat and UPM LabelCoat Prime can be used for a variety of other pressure-sensitive labelling applications.
