4 oxygen sensors
2 helium sensor – patented
2 methods of ppO2 measurement
2 independent computers
2 solenoid valves
Anything can go wrong. No single malfunction in the electronic system can cause a breakdown of the whole apparatus.
The unit is divided into two parts: the head, in which the electronics are concentrated, and the canister containing the scrubber.
All equipment, including fastening straps is secured to the backplate. They are firmly attached to the backplate of the first stages of the regulators. BCD is a wing type.
Both valves are rotationally attached to the backplate and thus comprise the lower attachment point for the pressure tanks. Therefore, the tanks do not have any rails or locks on the
The software’s main task is regulation of the partial pressure of oxygen in the breathing loop.
CCR Liberty has extraordinarily low breathing resistance. Breathing work 1.58 J/l at depth 100 m place the CCR Liberty among the world’s best.
The CCR Liberty is controlled by two interlinked computers.
Each computer has its own battery, two oxygen sensors, a pair of depth and atmospheric pressure sensors, and a helium concentration sensor. Each CU controls a separate solenoid.
Both handsets are identical. Pressure gauges are hose attached to the first stages of the regulators.
Hoses, counterlungs and the dive-surface valve.
Some important devices are attached directly to the counterlungs. The automatic diluent valve (ADV), overpressure valve, manual bypass valves.
When breathing, a diver consumes oxygen from air and exhales carbon dioxide. In order for a closed circuit to function, the rebreather must do the exact opposite: remove carbon dioxide from air and replace the consumed oxygen.
If you breathe on cold glass, it fogs. And what if you breathe for several hours on the inner surface of the air-mass treatment unit cooled by the water of the Arctic Ocean?
All connections within the parts of breathing loop are easy to disconnect for cleaning and disinfection.
The head assembly is divided to several compartments. Most of the repairs consist of an exchange of the relevant compartment. It is fast and easy.

The CCR Liberty has a range of functionalities, but there is one that it does not have and it will never have: It cannot make decisions for you.
