Valmet has launched a stand-alone wet end control package for paper, board and tissue machines.

The control product called Valmet Stand-Alone Retention Control (Valmet RET) can be used for retention and break-time headbox ash consistency management.

The supplier said it offers benefits for paper, board and tissue makers previously only available to the users of Valmet DNA process control and Valmet IQ quality control system.

Timo Rantala, product manager, automation, Valmet, said: “Utilising the Valmet Retention Measurement (Valmet RM3), low consistency measurement and control hardware with state-of-art model predictive control, the product enables users to take control of the wet end to a new level.

“Valmet RET improves paper quality in the machine direction by reducing variations in basis weight, paper ash and moisture.”
