CCR Liberty – presented at the BOOT Düsseldorf 2015 – is now available.
The rebreather is designed as a fault-tolerant. No single malfunction in the electronic system could cause a breakdown of the whole apparatus. And even multiple malfunctions often do not lead to a complete breakdown.
In case both handset cables are cut, the HUD cable torn out, and a hole to one of computer compartments in rebreather head drilled, the system functions sufficiently. The remaining control computer continues to maintain the oxygen partial pressure at the last setpoint.
So what if you are at one hundred meters below the surface and all 4 oxygen cells get damaged? The dive continues. For measuring oxygen indirectly are used the helium concentration sensors.
The same level of sophistication is applied also to the design and manufacture of all mechanical parts of CCR Liberty. Due to this, for example, the work of breathing is only 1.58 J/l in 100 m depth. This WOB puts CCR Liberty among the world’s best. It was tested at the Ansti facility in the UK (tidal volume 2.5 l, breath rate 30/min, heliox 10/90).
CCR Liberty is the first rebreather in the world certified without any exceptions or exclusions according to EN 14143:2013.
Training is available already with the IANTD. A few other technical diving training agencies are to follow shortly.
