The InVent development and technology centre is divided into 3 wings. The central air and noise test chamber for fans, the motor test bench with trial area, and the area for development teams with direct access to the test benches. The wing housing the air and noise test chamber assumes overwhelming proportions: the 1,250 ton concrete structure is supported by springs to prevent environmental influences such as vibrations and external noise during the sensitive noise measurements carried out on the fans.
InVent Development Centre
Volume flow rates of up to 100,000 cubic metres per hour as well as pressures of more than 3,000 Pascal can be generated by a measuring line weighing 325 tons. The measurements prevent any reflections occurring as would be the case under open air conditions. The base level is well below 15 decibels at 15,000 cubic metres. The test chamber procedures are certified and guarantee extremely high quality standards:
- Noise measurements according to DIN 3745 Class 1
- Air measurements according to DIN 24166 Class 1
- AMCA 210-99 certification
