Deaerator

Overview

The approach flow system connects the stock preparation facility with the paper machine. Here, the pulp for the paper machine is diluted to the required consistency. Additionally, the approach flow system ensures a smooth flow of stock. A particularly important element is the stock deaerator upstream of the headbox. It removes any entrained air under vacuum to ensure a constant, smoothly running process. For effective performance, the stock deaerator always has to be filled to a predefined, millimetre-exact level.

Inventory System

VEGA Inventory System (VIS) is a web-based software for real-time data acquisition, visualization, and logistics management of inventory levels in storage tanks and silos. Companies can manage their inventories proactively, ensuring greater flexibility in delivery schedules, expanding optimization options, and reducing stock discrepancies. Precise, real-time visualization of stocks allows deviations to be quickly identified, minimizing financial impact. The system combines reliable VEGA measurement technology for liquids and bulk solids with secure cloud-based or on-premises software, providing the basis for intelligent and strategic decisions for optimal inventory management. VIS supports both internal inventory monitoring and Vendor Managed Inventory (VMI) applications, where suppliers manage customer stock replenishment using real-time level data.

  • Real-time inventory monitoring across all connected storage locations via web browser or mobile app
  • Four visualization modes — Chart, Graphic, Map, and Trend — for comprehensive stock visibility
  • Color-coded traffic light status system (green/yellow/red) for instant stock level assessment
