Closed Circuit Rebreather Diving

All closed circuit rebreathers use oxygen diluent air trimix a breathing loop counter lungs a mouthpiece to deliver the breathing gas a scrubber to remove the carbon dioxide from the system and a method to replace the metabolized oxygen.

Closed circuit rebreather diving.

A closed circuit rebreather ccr employs advanced technology to recycle breathing gas in a closed loop system that makes the underwater experience virtually bubble free. Rebreather diving is underwater diving using rebreathers which recirculate the breathing gas already used by the diver after replacing oxygen used by the diver and removing the carbon dioxide metabolic product. Surface supplied diving gas reclaim systems a helium reclaim system or push pull system is used to recover helium based breathing gas after use by the diver. As an underwater cameraman the basic reasons that i switched from heavy dual tanks to a nice light rebreather unit like the inspiration evo are simplicity quietness.

Mccr manual closed circuit rebreathers. Closed circuit rebreathers give you the freedom and time to dive the way you always dreamt. Rebreather diving is used by recreational military and scientific divers in applications where it has advantages over open circuit scuba and surface supply of breathing gas is. Closed circuit diving rebreathers may be manually or electronically controlled and use both pure oxygen and a breathable mixed gas diluent.

That s the easy part and where other rebreathers stop but poseidon se7en technology really starts. These machines are cheaper and simpler than eccr s but require a whole new level of diver.
