Design Status of the Advanced Closed Loop System ACLS for Accommodation on the ISS

ACLS will be accommodated in an ISPR Rack which will contain all main and support functions like power and data handling and process water management. It is foreseen to be installed onboard the International Space Station (ISS) in the Columbus Module. After an initial commissioning phase ACLS shall be operated as a supplement of the ISS Life Support Subsystem thus enhancing its redundancy. Due to the regenerative processes applied in the ACLS it will allow a significant reduction of water upload to the ISS.
