JFD Global’s Closed Circuit Breathing System (CCBS) is an advanced, multi-person rebreather system designed to deliver precise decompression gases during planned surface decompression or treatment for decompression illness.
Efficient, electronically controlled, and fully integrable with existing chamber infrastructure, the CCBS is trusted for high-stakes operations where breathing reliability is critical.
Engineered for Safety and Efficiency
Supplied with Heliox 16/84 and 100% O₂, the CCBS dynamically blends and delivers the full range of decompression gases required by modern diving tables. Exhaled gas is scrubbed of CO₂, oxygen is replenished, and the mix is re-circulated—significantly reducing gas usage compared to open systems.
