Manual rEvo III
7
The rEvo III mCCR is a manually operated closed circuit rebreather based on the CMF
principle: (constant mass flow). During diving a constant flow of oxygen bleeds into
the breathing loop of the rebreather. The flow rate is high enough to provide a diver in
rest with a life sustaining breathable oxygen flow. The flow rate can be adjusted to the
individual metabolic rate of the diver. But it is kept low enough to be safe. During the
dive the diver controls and monitors their PPO2 with the help of the LED-indication of
the HUD and their handsets: when needed they can manually add oxygen through the
oxygen addition valve to maintain the desired PPO2.
It must be clear that the standard rEvo III mCCR is not an electronically controlled
rebreather: there is no computer which decides when oxygen has to be added: that is
the role of the diver. If they do not monitor and adjust the PPO2 regularly, this will
lead to hypoxia, unconsciousness and ultimately, death. (*with the optional hCCR
electronics, the rEvo becomes a fully electronically controlled rebreather)
Easy to setup, easy to transport, easy to dive and easy to maintain:
The rEvo III mCCR has been designed with one clear purpose in mind: simplicity in
setup, simplicity in use and simplicity in maintenance. The user has access to all
rebreather parts. Oxygen cells, ADV, orifice, scrubber-canisters, moisture pads can be
reached by demounting the main cover, removing one screw.
This unique design means that the rebreather has only 4 connections with O-rings
used by the diver: 2 for the breathing hoses and 2 for the main cover: the scrubber
lid (each with a double o-ring). The risk of leaking, wrong connections, wrong
assembly and forgotten o-rings has thus been reduced to a minimum!
