CORA 2 teardown

TR300 · 10th May 2006, 08:16

Hello rebreatherworld community,

today the new CORA 2 rebreather from Seaway has arrived.
It was first announced at the BOOT 06 in germany,
now some weeks later the first custom version are shipped and some
dealer training is in progress.

Now, just let have a closer look what we get:

The rig arrives with following components:

Scrubber made from stainless steel
the counterlung with breathing hose and mouthpiece
1.Stage regulator with any need connector, hoses and O2 finimeter
The head for SCR Mode with one gas

It is a complete system, all you need to add is a "normal" Jacket and 2 cylinders and also a bailout system (you can recycle your rec. OC gear)

This are all parts assembled together:

Scrubber:

now have a closer look to the scrubber canister,
the scrubber canister is made from stainless steel, At the outer side there are the two cylinder holder with two cambands on each side. The cambands are working from 2 Litercyl. up to 10 Litercyl, but when connecting a big cylinder the it would be a good Idea to hang the CORA2 a little bit higher, because the scrubber canister has the diameter 20cm and a hight from about 35cm

in the head of the scrubber there are the connectors for the counterlung and also the bypass with the orifice.

Inside the scrubber there is a plexiglas tube where the scrubber lives. the scrubber is holded between two stainless steel meshes.

Head:

the inner part of the scrubber head has the o-rings for thigthen everything

Counterlung:

Now have a closer look to the counterlung. The counterlung is connected direct to the scrubber cylinder. In the codura cover there is one PE-bag (logical cut in two areas). one area is the exhale (white marked), one the inhale side (black). On the exhale side you can see the adjustable overpressure valve (neccessary in SCR MOde an good to reach to adjust them underwater by yourself, very nice feature), the mouthpiece is small and one hand operable. The breathing hoses are very soft so it is no problem to turn your head.

just look at the inhale side, there is also a manual add valve (nice addon and I think also an option for future modes like mCCR and eCCR). on the lowest part of the counterlung are dump valves. I think it is in prior to clean the counterlung, perhaps with the right manover you can drain the counterlung (I will try this

)

I will add here some more infomation, if I had done my first exercises with the new toy.

Hi Holger,

some nice pictures of the new toy. Good to see that the process is going forward.
Is the CE-approval finished yet?

Cheers,
Christian

Hi Christian,

this should be the CE-Version, but I have to send back in near future the scrubber canister so I get lasered in the CE-Mark.

Thanks for the Info.

What's about the CO2-Monitor, is this also ready to dive?

Due to the finish in the pics, i guess it is a prototype ?

Hi Micha,

hmm this should be the most final version (my unit has the ser.# 0009 ) so I think this is it

we all know, that minor changes will occure in production, but the hole design will not changed.

The O2 and CO2 sensor combination is not to order, so I think it will take some more time to get them.

Hi to all,

last sunday I had a dive with the new Seaway CORA 2 rebreather.

I just fixed the rebreather on my good old PRO QD jacket, I added 2 x 2 kg in the upper trimweight pockets and 2 x 5 kg on the weight pockets.
I use a drysuit and a Weezle extrem underwear.

after some time diving I begin to play around with the overpressure valve and find a comfortable adjustment for the 6 l/min Flow.

just the mouthpiece was not mine (I will change them to an other one), the DSV works easy (onehand operable).

after all it was a dive with fun. The WOB was ok ( how it is with OTS counterlungs

)

after the Scapa Flow expedition I will have some more dives on the CORA 2. (no I take them not with me, because I have just a 6 l/min orificies)

Hello to everybody,

yes, this is the final design of the SSR I CORA Rebreather. The rebreather system is modular and by changing the cover you are able to change the mode of the system.
In few days we'll published the SCR II and mCCR cover. The eCCR will published on the show BOOT2007.
