at Venalum, Venezuela on a "turn key" basis. The order
value was € 11 million. This overhaul is part of a vast
modernization process. Venalum with an annual
production of 460,000 tons of aluminum and 320,000
tons of installed anode capacity is one of the global

players in the primary aluminum sector.
Using most advanced technology and logistics,
Riedhammer will perform the general repair of the ring
pit furnace, originally built in 1977 and first modernized
in 1992, during operation (between fires), thereby
minimizing the production loss.
A new, computer controlled firing system using "wireless"
technology, an optimized baking process, innovations
concerning brickwork, insulation and refractory
materials, as well as modern "light-weight" covers will
lead to a lower energy consumption, to a drastic
reduction of generated pollutants, a higher temperature
