Chest or Back Mountable Rebreather for dives to 60m
Safe And Compliant
Developed out of the British and Norwegian rebreather safety initiative for commercial North Sea divers, a 200 man-year project, the Incursion CCRs are believed to be the safest rebreather that can be engineered today. Full compliance with all applicable safety standards, with open publication of the safety documentation are cornerstones of the design: the test results, failure analysis, performance measurements and compliance matrices are audited and published for critique. The Incursion complies with the Gold Standard in Functional Safety, IEC 61508: it is the first military rebreather to be certified to any Functional Safety standard.
Dependable With Low Cost Of Ownership
The Incursion uses modern mass production techniques, including extensive use of injection mouldings, to create a very robust platform in which any subsystem or part can be swapped out in the field without tools. The parts are so robust, that a lifetime warranty is provided subject only to the equipment being serviced in the defined intervals.
Operating Principles
A rebreather recycles the gas exhaled by the diver, removing carbon dioxide and adding oxygen, to form a closed loop. This results no bubbles, low noise, and constant buoyancy and dive durations typically five times longer than for an equivalent weight of Open Circuit: gas consumption on a rebreather is independent of depth.
The Incursion CM stands out from older generation rebreathers, by a host of safety innovations and its extremely low work of breathing – allowing divers to swim much further and faster than before. One of these is the Micropore EAC scrubbers which are flood tolerant, and as simple to change out as a battery. The Micropore EAC has none of the caustic cocktail, dusting, tunnelling or handling risks of the old granular scrubbers.
The Incursion operates as either a pure oxygen rebreather, or as a semi-closed Nitrox or Heliox rebreather. To switch between these modes, the gas switch shown on the right is moved from O2 to SCR mode.
Switchable from O2 to Nitrox, Trimix or Heliox
- Use O2 near surface and switch to and from Nitrox underwater.
- Single knob control to switch from pure O2 use, to Nitrox. In O2 position, routes O2 to ALV (Automatic Loop-Volume valve). In SCR position, routes Nitrox to ALV, and routes Nitrox via a twin orifice to the scrubber gas port.
- Safety interlock: requires two simultaneous actions to switch from O2 to Nitrox, or back: press button down and turn.
- Proven Safety Principle: proven constant mass flow (CMF) using twin orifices, with choice of traditional high flow rates, or modern flow rates by adjustment of intermediate pressure.
- PPO2 Monitoring Option: When using modern low flow rates, Celebri PPO2 monitor is recommended, using three O2 cells.
The O2 to Nitrox selector converts the Incursion O2 CCR into an SCR when the selector is moved to the SCR position, but still retains the O2 CCR mode for use in shallow depths.
In O2 CCR mode, the Nitrox inlet port is closed off, and the SCR gas feed outlet is also closed. The O2 inlet is connected directly to the ALV outlet. The ALV (Automatic Loop Volume valve) allows the diver to purge the loop, and maintain adequate loop volume using pure oxygen alone.
In SCR mode, the O2 inlet port is closed off and the Nitrox inlet is connected to both the ALV outlet and also the SCR outlet. This outlet is fitted with colour coded twin orifices, to provide a constant mass flow.
