Honeywell

Honeywell re-engineered the CO2 scrubbing devices needed
ACE stepped up and did a full-court press on the production
Incredible accuracy and speed were paramount
Difficult metals, materials, milled sections, joints – all assembled perfectly
ACE made the launch, and helped keep our astronauts safe
Honeywell came to ACE with a huge problem. The Carbon Dioxide Removal Assemblies (CDRA) were failing in the International Space Station. Three were down, and NASA only had three left. Plus, there were only 42 days before the next launch window.
CARBON DIOXIDE “SCRUBBERS” FOR THE INT’L SPACE STATION
Carbon Dioxide, what we exhale, can be very dangerous to humans who are off-world in a sealed environment. Usually this unbreathable gas is collected and expelled from the ship. However, for long-term occupancy, this closed-loop CDRA “scrubbing” system removed CO2 and restored oxygen from it, enabling its recycling. And that significantly reduced the amount of breathable air that has to be delivered periodically to the station in tanks from the surface.
