yo

I got my hands on this passive SCR Rebreather, engeneering and machining made in Germany. Nice coating on all surfaces including inside the bellows. Ratio 1:8 with 3.2 kilo absorbent - any type, redundant injectors. It has a fitting to acomodate an Oxygauge but can be made to accept a VR3 as well.

The rebreather, mouthpiece with opencircut bail out regulator and frame ( 30 - 120 cft tanks ) are available seperate. The frame will be available as well soon to fit a Megadolon.

Right now the unit is passive SCR but in the future a CCR version will be available as well as some over the shoulder counterlungs. In the process as well is a bail out - sidemount version of this unit.

The same source is making me a sofnolime conversion cartridge for the CCR Optima, ready in May this year.

Hallo,

who makes this? Is there any source for technical details?

Hi Matt,
this SCR likes good.
Do you have more technical details?

More tech details here

- http://www.halcyon.net/rebreather/index.shtml

But seriously is this another RB80- clone? The BOV certainly looks exactly the same as the RB80 one.

Yo

After diving the unit a bit and talked to the master maker here are some bits of info. The units metal parts are saltwater resistant aluminum hard coated to resist corrsion and then teflon coated. The bellows are teflon coated in and out. Around 4 kilo absorbent. Any type of absorbent can be used. Frame is stainless and glass perled. The manufacturer has done 25 units already. He was working 10 years for Draeger as an rebreather engeneer, hence is understanding of rebreathers and is now working on a sub shipyard in Germany as an engeneer, hence his metal coatings. I am not sure what his end price will be but guess in the 8000 usd range, and that could be with bailout mouthpiece and frame. When I get the final price on it I will post it.

I'm currently diving one of them here in Switzerland.

I had the possibility to see the original RB2000 and the RB80. The production quality is far superior to both of the "orginals". Beside that it's an exact copy of the RB80. I had also the impression, that the breathing resistance is better (depends on the He mix).

Nice find Matt.

Very interesting Matt

Maybe this could be a good editorial piece for Advanced Diver Magazine?

Now, get off your butt and find some cave for me to lay line in. :-)

The pictures look nice, and a lot of attention and effort has gone into things like proper marking of the Draeger type hose clamps etc.

Interesting it uses Teflon coating. We eliminated all Teflon from our design work. It would be good if the manufacturer switched to a different coating for this product.

Over time, things that were thought safe earlier we find to cause us health problems. In a diving environment, this is acute because not only the environment is not our natural one, but the materials in a breathing loop are subject to gases being pushed into them, then pulling them out with compression/decompression cycles, increases off-gasing considerably. They then stay in the loop until absorbed by the body, or expunged by the loss of gas to the sea water involved in the ascent.

See The Silent Killer, by Joanie Doss for the effect on birds, just to be clear this is not just an imaginary risk. Also http://www.mercola.com/2005/feb/2/teflon.htm . The issue is severe at high temperatures (over 240C), but the background of this issue and the off-gassing problem in diving means that Teflon coatings, IMHO, would not pass a proper product safety review without hugely expensive biological tests. Much simpler to change to another coating.
