FDU rotary degassing equipment

FDU degassing units are an automated metal treatment system for the environmentally-friendly degassing and cleaning of aluminium and copper alloys.

FDU units use the impeller principle with a patented rotor which creates fine inert gas bubbles and mixes them with the melt. These fine bubbles are distributed homogenously throughout the melt without disturbing the surface maximising the contact area between the gas and the melt. The effectiveness of the Foseco FDU means that higher levels of degassing and cleaning can be achieved and treatment times can be reduced.

Metal Treatment Station (MTS) one-step automated treatment system

By using the MTS System (Metal Treatment Station) aluminium melts can be completely and automatically treated in one step. Whilst degassing with the proven FDU technology, all required treatment agents can be added at pre-set levels.

FDU XSR graphite rotor 

The XSR rotor type can be used in combination with all Foseco graphite shafts. Turbo cuts in the upper section of the rotor further reduce the size of the inert gas bubbles thus maximising the surface area of the bubbles for a given volume of treatment gas, resulting in fast and consistent hydrogen removal. XSR rotors are supplied in the impregnated condition to reduce oxidisation and extend service life.
