The killer sticky o2 button has been sorted

A customer has had an Apoc oxygen injector fail twice,
This problem was traced to use of contaminated oxygen.
Divers generally take care to avoid contaminated gas or cylinders: it is a safety hazard.
Oxygen cylinders must be free of detritus, including salt, rust, lol

Seem,s the customer is always wrong attitude , is still going strong at Open shite equipment ltd .

We moved our service centre from Glasgow in Q1 2017 in order to set up a dedicated Apocalypse
Rebreather service facility. Service times were extended substantially during this move, but are now
back on schedule. Normal service lead time for our recreational products is 6 weeks on recreational
dive products and on professional products within the declared service times.


love the useless Information they post ,

Tell me something useful if you have moved why not say were feeking to ,

Not all are saved, but I guess you know that already. Nice find mind.

An interesting opening statement they make: “We own all our IP for our surface supplied rebreather”
It doesn’t work on a sports divers forum but it does answer a number of professional diving questions.

EN14143, NORSOK U101 and IEC 61508 at the SIL 3 level again shows they are still moving ahead with the big picture plan.

Saturation Breathing simulators another “big stick” in the professional diving market.

ISO 9001:2008 to 2015 as well as 14001 shows the direction they are moving in and IEC EN 61508
with ATEX and Ex compliance will make it a full house.

Nine years has it been that long and still no one can beat 1.44j/L shame.
Makes the solid state sensor almost a piece of cake for them. Well done.

You may laugh at them and try and deride them from your position.
But just goes to show It takes continued skills to make state of the art diving stuff work.

When you have designed as much, built as much and innovated as much.
Then you can laugh.

In your case, you haven’t............ then all you can do is wait. :blush:

I know you love your messiahs Iain but this is a bit much, even from you. I can hear you hyperventilating from here. And what is my position that you refer to? Potential customer would be an accurate description. In fact, if OSEL have got real end-tidal CO2 monitoring working, I'll happily admit it was worth the wait. By real, I mean one that would actually measure end tidal CO2. Sadly, they often "exaggerate" somewhat... so I guess we'll have to keep waiting.

Iain,

I had prepared a post with all of OSELs greatest hits over the years that essentially demonstrate that your optimism and idolatry are somewhat misplaced. But let's leave that till later if necessary.

Perhaps for now I should offer to independently test the ability of this rebreather to accurately measure end tidal CO2. If they really think they have nailed it, what have they got to lose?

You can only put so much real estate on a dives back, and if that space is used for the SECONDAY life support , then its safe to say your fooked .

If no bail out and rotowink says all,s good ,
How often are your eac.s :x: / consumables replaced , 3 units per bell. may keep you both in cheap court shoe,s
Just more wordsmithery and bollox .

Pdf on the extend air cartridges please.
along with a pdf with the avg number of bailouts per year in commercial sat diving lol

talk about getting bit in the arse ,:grin:

Think i read,
that a part used micropore EAC can sit in the arse end of a apox for two week,s and still be used. So id think one EAC that,s unused would OUT last a 3 week sat run.

Brad also wanted to ask if you could say how the online training/annual tune up was going.

Only ask as iv seen no apox divers out and about this year did they all fail

Your Apocalypse Type IV iCCR carries out a set of checks each time you
use it. Those checks may indicate a fault. If you cannot correct the fault
yourself, without using tools, then return the unit to a factory appointed
service centre.
Material and design faults are covered by warranty for the
life of the product, where the rebreather has been
properly maintained.
The electronics and the gas system of the rebreather has to be returned once
a year for a factory service.
This replaces O Rings, replaces the oxygen sensors, checks the unit, and performs any safety upgrades that may not have warranted a recall. There is a charge for the
annual service.
You too need an annual tune up: you will need to go on line to
www.deadlife.co.uk/training.php and enter your unit serial number, then it will provide any updates you need and reminders through a short Question-Answer form.
The On-line training will verify your contact details should we need to do a
product recall or field upgrade, and then ask some questions to remind you
of the theory needed to use your rebreather safely,including a simulated
dive with faults. You should assign 30 minutes to this process.
When you pass the skills reminder, and then enter the PIN code into your iCCR for
another happy year of diving.
If you leave the On-line training for more than 18 months then your iCCR monitor will not function: it will warn you of this
.
If you fail the on-line training, then suitable self-study training material will
be sent to you, which may include .MPG videos or parts of manuals. Study
that and retry: the questions will be different but themes the same. If you
fail this, then you need to contact an instructor to retrain you and enable your unit.
For your own safety, and that of your dive buddy, if the factory service
reveals particularly dangerous dive practices, then you may be asked to take a more rigorous skills test.

Talk about delusions of grandeur lol

A new PDF, lol. Nice to see the unreleased iCCR is being updated, in secret, with no sales or customers.

In case it changes I've based this gem paragraph here. Let's wait for Brad or Alex (assume he is banned though).

When will we get the answer to the end-tidal question posed 10 years ago on Yorkshire-Divers?

Matt.



5. iCCR Monitor Shipping StatusOur iCCR Monitor is the only product we have on hold – all other products that have passed certificationare in production and are shipping.Our iCCR is fully CE and Functional Safety certified. It is on hold simply because we identified anadditional hazard in field data from accident analysis of recreational rebreather fatalities on a thirdparty's rebreather. That hazard is the user ignoring a reported NO DIVE status and diving due to beingin a remote location that has taken a lot of effort to reach, at high cost, along with a good measureof peer pressure. As a result of more than one of these incidents, we made the decision to upgradethe actuator mechanism in the ALVBOV to deal with this new issue, before we sent large numbers ofiCCRs out. This has been done and we have been working through the rest of the functional safetyprocess with regard to that change.At this time we are anticipating that the iCCR Monitor fitted with solid state O2 sensors operatingalongside traditional galvanic O2 sensors and end-tidal CO2 monitoring will resume shipping by theend of 2018.We have refunded all iCCR Early Adopter (EA) who requested this. All iCCR EAs can also switch toany of our other products, at heavily discounted rates, just by contacting our support team.

On various CCR forums, yes. Lots of old science posts. Last time this happened, it was "revealed" that water on cell faces can cause problems. That may or may not have been something to do with a certain court case that was about to take place and "expert witness".

But was looking back to 2020 and was thinking that the apox must have lost its clame on being the safest breather in the universe. As all other units are now getting used as much as the 13 apox units sold to date . Seems safety between one unit and a nother had balanced out . And the apox is was just a nother run of the mill idea that never made the grade . :think::D

This made me chuckle and reminded me of a classic Deas quote from 2009:

"Clever divers order a working and fully tested life support system, designed by professional engineers with global resources, AND get trained to use it: the Apoc iCCR.

The dumb divers want to buy an O2-CCR then design and build at home their own life support system for the first time, with the resources of their local hardware store, take it to the sea without any review, dive in the water without any training, and become test pilots on their own creation because nobody else would be so crazy as to try it out".

See, you should have ordered the iCCR. The fact you would still be waiting for it 12 years later is a minor technical point.

Funny we have a face ache group for custom built CCRs there are more of us on there "test piloting" units on some proper dives than there are poxes ever made.

I'm also a member in that group. I suggested to a friend to buy a second hand O2 Apoc for cheap parts. I really like the BOV, improved P-connectors and O2 feed button. Albov is quite compact when you see it live. That's what I'm recycling for a FM unit.

I didn't like how the Apoc with BM lungs breathed in water. I also ordered two O2 tanks and both were faulty. http://plazma.kapsi.fi/pictures/temp/valve_clearance.JPG

IIRC I canceled my iCCR order in 2012 and took the O2 unit instead. By then it was already clear they will never finish the iCCR.

This seems at odds with all the OS hype. What did you not like?There was already talk back then it required slightly heads up trim. Diving vertical causes higher negative pressure to diver lungs.
But that is also problem for other BM counter lungs units. It depends on how thick the counter lungs are. As seen in figure C in this document

It's almost like they might be lying ambulance chasing shysters isn't it?It's the way CE tests are defined. It only calculates the surface area inside the "Lissajous" curve. It doesn't calculate negative pressure to WOB. There are only limits for hydrostatic imbalance (+-20mbar from lung centroid). For human lungs it doesn't matter if the pressure comes from resistive flow restriction or hydrostatic imbalance.
For CE WOB calculation you get the same result for same curve shape even if its around the 0 x-axis or clearly below or above it.

He with no name is no doubt working hard trying to save us all with his next dig idea.
That or him and Brad are hunkerd down at the Portuguese villa/HQ and enjoying a 2nd honeymoon.

It's the way CE tests are defined. It only calculates the surface area inside the "Lissajous" curve. It doesn't calculate negative pressure to WOB. There are only limits for hydrostatic imbalance (+-20mbar from lung centroid). For human lungs it doesn't matter if the pressure comes from resistive flow restriction or hydrostatic imbalance.
For CE WOB calculation you get the same result for same curve shape even if its around the 0 x-axis or clearly below or above it.

Wasn't always this way. Prior to latest EN14143 (2013) the earlier version had max inhale/exhale pressures mandated at 25mbar. So the top and bottom of the Lissajous had to be between these levels (and so be centralised fairly close to the x-axis). Also had slightly greater limits for hydrostatic imbalance in certain orientations (+23/-25).

And the old 2003 version:

Just in case someone wants to take a look. I also bought the 2013 version but can't share it publicly.
