Absolut System started to develop centrifugal compressor for its own Reverse Turbo Brayton coolers, since centrifugal compressor is a key element to provide a compressed flow with maintenance free and contactless system.
Our centrifugal compressors are based on hydrodynamic bearings to avoid any contacts and are thus a system of choice for thermal management of space systems. Similar systems have already proven more than 10 years nonstop use in space without any performances alteration.
We use numerical modelling extensively to optimize aerodynamic efficiency on one hand and mechanical aspects on the other hand (rotodynamic, wheel integrity).
