Forming Section Vacuum Control

 

As demand increases for efficient use of energy and precision in papermaking, the need for reliable and accurate vacuum control on the wet end of the paper machine has never been greater.  Kadant provides all the tools necessary for today’s papermaker to optimize their vacuum control system.

 

V-1000 Vacuum Control Valves

Electronic Interface System (EIS)

Dynamic Drainage Control
Precise, automatic control of set point vacuums is required in both low and high vacuum systems.  The V-1000 Vacuum Control Valves provides this accuracy despite fluctuations in stock and vacuum supply. Designed specifically for use with V-1000’s, the EIS packages allow pneumatic/electronic communications with the mill DCS system to optimize performance.  There are four EIS packages available depending on your mill operating system. Kadant can design and provide a closed-loop system that continuously senses and responds to changes in operating conditions to maintain optimum sheet consistency.  Fully integrated with the mill DCS, the DDC system is perfect to control consistencies leading into a dandy roll or top wire former.

 

Single-Stage Blowers with Auto-Surge Control

Vacuum Control Piping Systems

Low Vacuum Manometer
Kadant provides a complete systems approach consisting of a low vacuum source and a surge protection for the high speed centrifugal exhauster.  The exhauster is much lower cost and more efficient that from 0 – 60” water column than liquid ring pumps. In order to maximize results, all aspects of the vacuum piping system need to be reviewed.  Effective air/water separation and management of air flow velocities are critical to the success and energy efficiency of the low and high vacuum systems. The 0 – 60’ water column low vacuum manometer provides easy and effective way for the papermaker to view vacuum levels while working on the paper machine.
