Smelters gain benefits with RuC®:

  • Rodding avoidance: delivery of assembled blocks with metal parts, reduced health & safety risks
  • Energy saving (lower SEC) + better pot stability (lower noise level) + increased productivity (higher CE, improved current creep)
  • Extended pot lifetime: more consumable cathode material and reduced peak current density
  • Copper recovery with high return

These highlighted benefits result in a visible and significant economic advantage and lower CO2 emissions for a greener aluminium production. RuC® increases the operational margin in aluminium smelters.

We are designing and delivering RuC® for all smelting technologies worldwide. With our technical service starting from cell lining design through to installation and start-up, customers receive full support from Tokai COBEX.

Over the pot lifetime, we stay in close contact with our customers to ensure the full achievements of all RuC® benefits.
