Our Systems
Caeli Technologies is a pioneer in next-generation rebreather systems for tactical teams and first responders. We build hybrid breathing apparatus that give elite operators the freedom to breathe in any environment – from contaminated battlefields to confined tunnels – far longer and safer than ever before.
Our flagship CRUSOE series rebreathers offer up to 12 hours of continuous protection (versus ~4 hours for standard units), and have been operationally proven by special operations forces and first responder units worldwide (Technology Readiness Level 9). When missions demand innovation, survivability, and trust, Caeli delivers.
