Closed Circuit Rebreather

A Closed Circuit Rebreather (CCR) is a sophisticated breathing device used by divers to recycle their exhaled air. It removes carbon dioxide and reuses the remaining oxygen, allowing for longer dives and less gas consumption compared to traditional open-circuit systems. The system monitors oxygen levels continuously and automatically adjusts oxygen addition to maintain safe breathing conditions. This technology minimizes bubbles and reduces noise, making it ideal for scientific, military, or underwater photography applications. While requiring specialized training, CCRs enhance diving efficiency and safety by optimizing gas use and reducing environmental impact.
