50th International Conference on Environmental Systems


The Air-Cooled Temperature Swing Adsorption Compression System (AC-TSAC) was designed to be a viable alternative to the carbon dioxide (CO2) mechanical compressor currently in use on the International Space Station (ISS). The AC-TSAC would be integrated downstream of the Four-Bed Molecular Sieve (4BMS) CO2 removal system and upstream of the Sabatier reactor system. The previous generation of the AC-TSAC system was dismantled and has undergone a significant upgrade to modernize the system and resolve system failures.
