    Azimuth Tanks - Convert to DIN

    Now I may be heading for warmer waters and I suspect I may have a little fun with getting the tanks on the azimuth filled...

    So either going to get my own filling adaptor

    OR was thinking........

    Can get the bits to convert the MR12 first stages to DIN (around 15 quid per Reg), and then replace the tank valves with DIN convertible A-Clamp valves which can be filled anywhere...

    Sure someone has already thought of (or even done it) but my thoughts as follows

    + gets rid of the easily damaged external threaded valve problem
    + easier to find fills
    - loss of CE compliance - would have to keep bits for when unit sold
    - new valves may be a bit longer
    - would need to either use left handed valves or use the regs underneath rather than on top...

    Any thoughts / suggestions ?
    Thanks in advance

    Re: Azimuth Tanks - Convert to DIN

    Yes I have partly done away with the odd valves/regs. A problem is that most valves that fit the 4l-cylinders will be very hard to fit in the unit without cutting the chassis and without sticking out a bit to much.

    I found a low profile standard DIN valve that will fit in the chassis with an Apeks DS4 first stage on it. Its a single exit version of the valve on this picture: http://www.divex.se/nitrox/2X6300n.jpg

    Since I live near the store selling these valves (Välkommen till Divex!) it was easy for me. But I know that OMG (Azimuth producer) also sell M25 Air-DIN valves that will fit the Azi (probably rather expensive...). I think there is also a German company (Aircon) selling valves that could fit.

    Anyway, if you convert to Air-DIN, why not change for say Apeks DS4 and maybe even cap the membrane to get a fixt IP. So as to get a more 'conventional' CMF-SCR setup (Give that you adjust the IP correctly). Caps for fixt IP and cheap DS4-first stages can be bought from:Tauchen - Cave, Nitrox, Rebreather Ausbildung, Tec Ausrüstung, Reisen

    I did those changes as a part of converting my Azi to a KISS-style MCCR.

    Re: Azimuth Tanks - Convert to DIN

    Just thought you might like to know. When I got my Azi about 5 years ago it came with din fitting cylinders and first stages already. It might be worth contacting them direct as they do produce the Azi with Din fittings:)

    OMG sell the DIN 200 bars valve for the Azimuth (short, wright side/90°angle ...) either in M25x20 or 3/4-14NPSM threads. I bought a few a year or two ago for US$175 a pop.
    Contact OMG, Sanosub or your distributor in your country.
    Changing the MR12 over to DIN takes 2 mn per reg. but you'll probably want to service them at the same time as long as you're messing with these spanners.

    Re: Azimuth Tanks - Convert to DIN?

    Many thank to everyone, looks like a very viable option and getting suitable valves should overcome any potential problems. If I can get the correct ones from OMG then the the CE mark should still be valid...

    Probably heading to the Diveshow this weekend (NEC, Birmingham, England) so will have a look there too.

    Yes Philippe, I'm going to service them at the same time, presumably the intersage pressure is set to the same as normal open circuit MR12's (my book's not to hand but from memory 12's and 16's are 9 bar and Abyss 9.5). I'll check what it is now...

    Thanks again

    Andy

    Andy, Check the IP carrefully on the manual.
    on the Azimuth SCR, it is very important, as in if-you-screw-up-you-can-die, for a consistant flow rate that you set the the second supply tank that's used after you flip the lever @ a slightly higher IP than the main cylinder. I used to set this second MR12 @ 9.2 bars and the first @ 9.0 bars, but that was a few years ago and my memory can play tricks on me so you want to check that with an Azimuth service technician.
    Best

    Thumbs up Re: Azimuth - Setting (different) Interstage Pressures

    Thanks Philippe, deliberately setting the reserve IP higher is brilliant.

    Guarantees the reserve flowrate will always be slightly higher.
    i.e. once the main is set correctly the reserve flowrate will always be a little more... Yes, I know its still essential to check that the minimum flow for the given mix is exceeded for both tanks.

    I must admit that I probably would have just setup both regs the same on the bench as per normal open circuit Mr12's.

    I suppose I had always thought that both regs were setup identically. That there was bound to be inevitable natural variations between the two regs, and that because of this, there was such emphasis on checking and double checking the flow was exceeded with the reserve lever in each of the positions.

    Cheers

    Andy

    Thumbs up Re: Azimuth Tanks - Convert to DIN

    Well guys, quick update on how it went

    OMG / San-o-sub didn't even bother replying but I got a couple of pillar valves from underwater france

    Already O2 clean and 104 euro the pair inc. shipping

    http://www.underwater.fr/FicheProduit.asp?NumProduit=185

    They are ideal in that they are low profile and the regulator position is only different by a couple of mm. Plus the valves are now on the side rather than round the back - just a little bit easier - overall very satisfied. (You don't realise how crappy your valves had got 'till you get new - the external threads had been dinged a few times and the regs were hard work to fit)

    The Regulator conversions to DIN came from Diveinn Scubastore

    Din conector mr12-v12-r2 300b MARES Spare parts Regulators United Kingdom Dive Scuba store .com

    so the whole job came in around the £100 mark.:D

    I did get some other spares from Diveinn and enquired about some Mares bits but got an email that when current stock is gone, they will no longer be stocking mares spares, which will be a bit of a shame as they are great for reg service parts and are good to do business with.


    Thanks to all who helped with this, your advice was appreciated.
