Submatix UK distributer

[Luddite]

Hi all


Just to let you know I have bought a share in the submatix UK distributer. Its a bit of an exciting time for me. Please feel free to asked any question on the units. If I can not answer them right away I'll go and find out and get back to you asap. Anyway I'll stop there before I get a cuff around the ear for advertising

Here's my first question:

How does a kiss-style mCCR pass section 5.7.1 and 5.7.2 of BS EN 14143 to get its CE mark for PPE?

----------------------

5.7 Gas control or supply system
5.7.1 Inspired partial pressure of oxygen
The apparatus shall under all conditions of use specified by the manufacturer automatically maintain an inspired partial pressure of oxygen greater than 0,20 bar. The inspired partial pressure of oxygen shall remain within the limits specified by the manufacturer. The inspired partial pressure of oxygen shall also be maintained at a partial pressure of less than or equal to 1,6 bar; except during the descent phase(s) of a dive for a period not greater than 1 min where it may increase to a maximum of 2,0 bar. In the event of a failure of the automatic system provision may be made for the addition of respirable gas by the diver. If fitted this shall also be able to satisfy the inspired partial pressure of oxygen requirements of this clause.

5.7.2 Oxygen partial pressure setpoint maintenance
In apparatus with a fixed oxygen partial pressure setpoint the inspired partial pressure of oxygen shall be maintained within +/-0,10 bar during constant depth phases of the dive. This at a ventilation of 40 l min-1 and
associated oxygen consumption of 1,78 l min-1.
During the ascent phase the inspired partial pressure of oxygen may reduce to a minimum of 0,5 bar below the set point but shall regain steady state set point within 1 min of halting an ascent.

------------------------

The only way I can see an mCCr passing this is if it is run as a pure O2 rebreather and limited to 6m depth.

That old chestnut. As you pointed out can any mCCR pass that. I am not going to start another back and forth argument in this thread I think it has been done to death as it is. If I get any further developments along this line I'll happily post them. At the end of the day you pays your money and you makes your choices. My choice is a submatix, I do dive on an SCR and in the new year I'll be upgrading it to a mCCR. For me it does what I want it to do. I am not a Tech diver or deep wreck ferret. I am a recreational diver and the submatix is a recreational RB.

jon,
excuse my ignorance but what does this exactly mean?
cheers,
les

ps. still wanting 200bar x 2litre bottles!

CE seems like a fair question. Why would depth that it is used at be relevant? As Woz says, anything deeper than 6m then it can't maintain a stable PO2 unassisted.

Cheers,

He has made a business decision that some of us would rate as on the level of sending your account details to a Nigerian banker in need of a next of kin to launder some funds but we wish him well with it.

I haven't seen a Submatix close up since the first incarnation diving with the first UK Distributor and, thankfully, it could only have got better since then.

It's a serious question and one that I haven't had answered yet. It might have been done to death somewhere but I'd really like to know how the Submatix gets its CE mark cos for the life of me I can't work it out.

I'm not taking the piss. It's a serious question. And I would really like someone representing the Submatix brand to give me a definitive answer. Cos at the moment the CE marking looks, well, somewhat shakey.

OK give me some time and I'll look into it. I am by no means an expert on the subject.

Thanks I really appreciate it. I've trawled through the RBW archives and just come up with a load of Machinery Directive stuff and no definitive answer as to whether the Submatix is CE marked as PPE. If it is, there are lots of implications for other mCCR manufacturers, for example Revo and KISS stuff.
