Innovative Air Revitalization for Space Missions

Honeywell’s  next-generation Air Revitalization Systems (ARS) deliver continuous, scalable and contaminant-tolerant, life support for harsh space environments. Built on decades of CO₂-removal expertise and full-scale prototype testing, our systems combine Carbon Dioxide Removal by Ionic Liquid System (CDRILS) and Methane Pyrolysis (MP) to recover nearly 100% of oxygen while tolerating humidity and trace contaminants for space stations, lunar habitats and deep-space missions.

Next-Generation Air Revitalization: What Sets Us Apart

Experience  cleaner, more efficient life support that reduces mission costs, boosts autonomy and maximizes oxygen recovery. Our patented, closed-loop technology ensures sustainability and confidence.

Cost control

Mission Efficiency & Operational Reliability

• Lowers mission life-cycle costs
• Scales to crew and duration
• Integrates with other air systems

Minimize Downtime

Autonomy & Environmental Robustness

• Supports crewed missions, in extreme environments, with low maintenance.
• Robust against contaminants.
• No soot, clean closed-loop process.

Ease Repair Burden

Sustainability & Technology Leadership

• Stops overboard venting of CO₂, enabling near-100% O₂ recovery
• 20+ patents covering CO₂ removal and Methane Pyrolysis advancements.

The Science Behind Our Systems

Honeywell’s Air Revitalization System (ARS) is a closed-loop environmental control and life support solution designed for long-duration spacecraft habitats. Utilizing advanced ionic liquid technology to continuously remove CO₂ and contaminants, paired with Methane Pyrolysis (MP) to recover oxygen from CO₂, ARS helps eliminate costly resupply missions and outperforms traditional systems that vent CO₂ overboard.
