How it Works?
On breath exhalation the exiting gas from the
body, low in O2 and rich in CO2 returns to the
Rebreather.
Then by pass the top canister where the CO2
absorber is placed, the gas then travel directly
into the flexible counter lungs, the inside
counter lung let's out a 10th of the available
volume with any water intrusion.
On breath inhalation gas flow travel through
CO2 scrubber, back into the lungs to
complete the "LOOP"
Notice that a reduction in inspired FO2,
oxygen percentage in the mix, occurs on each
breath and therefore changing current PO2
"dropping it". Until just a portion of "fresh" gas
is injected and partially raises the Mix FO2.
This is referred as "O2 drop" the main reason
of accident in this unit type.
We have developed "Touzil System" a
propietary software that can predict O2 drops
base on segmented "K" factors.
Part of this software assist in establishing
personal "K" factors, depending on user and
rb efficiency, in ascent, descent and at
bottom. Both under workload and at rest
We recommend the application of PO2 / FO2
monitoring devices until full understanding of
O2 drop.
Some pSCR's exhalation gas goes around
the canister in the outside, not in the inside
like rb2000 clones. This reduces BOV and
keep sofnolime warmer, besides making it a
lot easier to load sofnolime.
The NT rbs we make can also have radial
canisters, which reduces the BOV dramatically

The fridge
Was way more complicated to use,
minding a large case, tuff
maintenance and during dive water
intrusion hand pumping and even
pressure assisted breathing!
However the mechanism is virtually
the same, even not as effective.
