The IPU Project – ISAL Production Upgrade – will increase the amperage to 181 kA in Lines 1 and 2 of ISAL‘s three-line Alusuisse EPT-10/12 technology smelter to achieve an additional aluminium production of 44kt/y.

Anode rod stub diameters will be increased and anodes enlarged in all three potrooms. Busbars in potroom basements will be upgraded and pot superstructures modified.
