Multiline analyzer for stable wet end processes

Valmet Wet End Analyzer (Valmet WEM)

Valmet's multiline wet end analyzer in use

The Valmet Wet End Analyzer (Valmet WEM) is a modular online measurement solution that provides tissue, board and papermakers with all the key variables for effective wet end management.

Improve runnability and quality with stable wet end consistency and chemistry

Optimize and reduce chemical, water and pulp usage based on actual process properties

Limit maintenance and downtime through machine cleanliness

Valmet Wet End Analyzer (Valmet WEM)

Stabilize the wet end for best performance

A stable wet end is essential for optimal board, tissue and paper-making conditions. Achieving stability, however, is a challenge given the increasing complexity of chemicals, pulp blends and environmental impact. Valmet Wet End Analyzer (Valmet WEM) gives you the breadth and depth of measurements that enable you to bring all wet end processes under precise control.  

From headbox to effluent, this multiline analyzer helps you create the best wet end conditions for stable quality and high runnability with the lowest overall cost and environmental impact. Reap the benefits from proven, advanced online measurements covering everything from pulp properties to consistencies, ash content, charge and chemistry. 

Valmet WEM can be used for a wide range of wet end applications including paper, board and tissue machines of all sizes, RCF, DIP lines, and water cycles. 

Optimize consistency through automated control 

Valmet WEM provides continuous online sampling of total fiber and fines consistency and ash consistency from up to three lines. Combine these continuous measurements with the Valmet IQ Quality Control System for fully automated consistency control, ensuring white water properties remain stable and robust against process disturbances. 

Valmet WEM also enables automatic charge control. With a stable charge, you get a steady effect from cationic chemicals, fewer defects, and a stable release angle on center roll. 

Ensure target quality through fiber analysis 

Valmet Wet End Analyzer includes a full fiber imaging module using advanced imaging technology from field-proven solutions such as Valmet Fiber Image Analyzer and Valmet Fiberline Analyzer. Ultra-high-definition camera optics and intelligent image processing deliver detailed insight into key headbox fiber properties impacting end-product quality. Through precise morphological analysis, you can optimize fiber blends ratios and precisely dose retention chemicals. 

Flexibility to scale to your needs 

Thanks to a modular design, you have the flexibility to implement wet end management and control exactly how you need it. Collecting data from up to 16 separate sample points, each analyzer can be tailored with the measurement lines and modules best suited for your specific production context. Start with your most urgent measurements and expand from there, adding more measurements and sampling points as needed. 

The modular, robust construction also improves safety and uptime, reducing overall cost of installation and lifetime ownership. Built-in and remote support and diagnostics through connectivity ensure high uptime.

Production profitability by controlling your stock preparation and wet end process

Stock preparation and wet end processes are typically full of unknowns for board and paper makers. But controlling these process areas will enable optimization to gain energy & chemical savings, uniform quality, and better machine runnability.
