JJ-CCR Rebreather has been designed and tested since 2006 with more than 1000 operating hours under water in different locations around the world. This year we have benn at Qinetiq in England for testing the rebreather toward the EN14143 standard.
Why is the JJ-CCR Rebreather K.I.S.S simple?
- Redundancy is very important, separate batteries for handset, HUD and solenoid, none of them inside the loop! If the handset goes down you must be able to fly it manually on the secondary (HUD) and that should be as unaffected as possible by the failing of the primary.
- The electronics must be easy to understand, give some warnings but not give the "auto pilot" effect of some of the other units. The user MUST be made to feel he/she is the only one in control!
- The rebreather itself must be strong, versatile, reliable and easy to use, maintain and service. There should be easily obtained parts that can be replaced in the field if needed (E.g. standard scuba hoses). There should be a choice of configuration (E.g. BMCL's or OTS CL's) and it support a wide range of cylinders (3, 5, 7, 10 or 12 liter) without the need of special parts to attach them.
- It needs to be priced fairly, not stupid money but not cheap as chips either.
- But most of all it should have sound scientific test data to back up the performance claims. A few guys diving it and saying "well I am still alive so it must be ok" is not good enough!
We have tried REALLY hard to do all of that!!
