Multiline analyzer for stable wet end chemistry

Automate wet end control with a strong baseline

The 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 circulations.

Automated control of white water consistency ensure higher wet end stability, better runnability and ultimately better quality. The 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.

Measurements tailored to your needs

Thanks to a modular design, you can combine optional modules to measure charge, chemistry, retention and turbidity. The Valmet WEM delivers enhanced measurements for superior wet end management and control, exactly how you need it.

Analyzing as many as six separate sample points, each analyzer can be tailored with the measurement lines and modules needed for a specific process. Up to four measurement modules fit into one analyzer cabinet. Once installed, you gain immediate insights into wet end dynamics.

The modular, robust construction also improves safety and uptime, reducing overall cost of installation and lifetime ownership. Built-in and remote diagnostics through the Valmet Industrial Internet connection, ensures that the extensive expertise of Valmet is never far away.

Measurements

• Charge
• Chemistry (pH, temperature, conductivity, and redox)
• Total and true ash consistency
• Total and ash retention
• Ash content
• Turbidity

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.
