Design Status of ARES for Accomodation on the ISS

During the last years extensive work has been done to design and develop the Closed Loop Air Revitalisation System ARES. The potential of ARES e.g. as part of the ISS ECLSS is to significantly reduce the water upload demand. The current activities concentrate on the development of a full-scale demonstrator with ‘engineering model’ quality. The demonstrator will include the functions of CO₂ concentration, CO₂ reduction and oxygen generation. All components will fit into one ISPR. The design will minimize the number of external interfaces in order to achieve a high degree of independence with respect to accommodation on the ISS.

The paper describes the current development status and touches on critical technology tests for performance optimization.
