Renewal of the compressor system and dismantling of the pressure tank system as well as the associated installation services:

At the Institute for Fluid Mechanics and Aerodynamics at the University of the Federal Armed Forces in Munich, compressible flows are investigated in transsonic and supersonic. To carry out experiments in the context of research and teaching, the institute has the “Trisonic Wind Tunnel Munich” test facility, hereinafter referred to as TWM.

The TWM is an intermittent test plant in which compressed air is initially stored in a boiler system at an overpressure of 20 bar for each wind tunnel test by means of compressors. The size of the boiler volume determines the duration of the test. The boiler plant, which was built around 1980 and has a volume of around 350 m3, has reached its load limit and needs to be renewed to ensure the safe operation of the TWM in the future.

Goal and purpose of procurement: target condition

This tender covers the dismantling of the existing compressor system and boiler system, as well as the construction and integration of a new compressor system. The compressor system to be integrated is intended to replace the existing compressors. The cost-effectiveness of the old system is no longer ensured. The spatial requirements for renewing the compressor system are dictated by the cellar room in which the old system is currently located. Access to this cellar area with the largest possible cross-section is located in the basement ceiling and is only 2.0 m x 2.5 m. This access requires the old compressor system and the old boiler system to be removed. The new compressor system must also be brought in through this access.
