The indispensable tool for new
or upgraded potlines
Towards unprecedented performance
Whether with the more advanced Rio Tinto Alcan
AP60 pot or an older technology, ALPSYS® boosts
the performance of your reduction process by:
• Maximising current efficiency through tight control
of anode/cathode distance, bath chemistry and alumina
feeding along with easy detection of abnormal pots;
• Controlling voltage and energy consumption;
• Reducing the anode effect rate and related gas
emissions (an anode effect rate below 0.03/pot/day
is easily achieved using modern pots equipped with
ALPSYS®);
• Increasing labour productivity through a work
management programme, data compilation and
reporting up to the monthly level;
• Providing easy access to pot parameters for potline
operators and staff.
