Large Scale

In addition to the laboratory facilities, a large-scale test rig was built and put into operation at the INVENT Headquarters in Erlangen in 2008. The largest test vessel has a total volume of 700 m³ with a maximum filling height of 8.5 m. A blower station with 2 adjustable rotary blowers is available for aeration measurements. The test facility is used for measurements on the original scale and for acceptance tests before delivery. Here the findings acquired from the laboratory and at the pilot plant scale are validated in a large-scale trial.

For mixer dry tests a test stand has been set up which enables dry running at all standard shaft lengths.
