The CALGAS 3500 system combines the benefits of rotary degassing and flux injection to help improve the quality of aluminium alloys, and reduce operating costs.

In rotary degassing / fluxing systems, a metered amount of inert gas or flux is injected into the molten aluminium through a rotating graphite shaft / rotor. The rotor shears the inert gas into tiny bubbles and disperses them evenly throughout the molten metal. Unwanted hydrogen gas and non-metallic inclusions are attracted to the inert gas bubbles and rise to the surface. The flux injection allows a steady flow of flux below the metal line which promotes oxide entrapment.
