Celtrol

The Next Generation Control System for Improved Potline Control

The efficient use of energy is one of the most critical problems facing today's aluminum industry. To meet this challenge, The Automated Systems Group offers the CELTROL System, a distributive microprocessor control system that automatically monitors and controls reduction cells. In fact, the CELTROL System increases the amount of metal produced from a unit of energy because each pot controller is a computer designed to optimize the process on a real time basis. The CELTROL System provides extensive pot information to the operator at the cell.

Worldwide experience with the CELTROL System demonstrates that it is the ideal control system to:

Reduce energy costs and increase productivity
Minimize environmental impact by reducing occurances of anode effects
Control old and new smelter installations
Extend the useful life of older smelters

There are three major components in the CELTROL System: a microprocessor for each reduction cell, a communications buffer for a group of pot controller microprocessors, and a supervisory, or host, computer for the complete system.

Existing CELTROL installations can be upgraded to new CELTROL capabilities without extensive hardware modifications.

Reduction facilities worldwide are experiencing the benefits of our new and improved CELTROL System enhanced graphics that communicate more information faster; have more built-in controls that produce faster action in the pots, and waste less energy.

The control for the CELTROL System can perform the following process control functions: Automatic Voltage Control, Noise Control, Tapping Routine, Anode Set Routine, Alumina Feed Control, Search Routine, Starve Routine and Anode Effect Termination. The CELTROL System makes better use of incoming power, helps to maintain proper heat balance in the pot to provide lower bath temperature, and produces more aluminum from the available energy.
