AZi conversion to CCR

MHD

Heres an overview of my recently completed Azi conversion to CCR.

Like all units I have some fine tuning to do regarding trim and hose routing, but pretty much meeting expectation. Am amazed at the difference fish show to this even compared to the Azi when it was SCR.

Hey Matty
What a dead sexy box you have created, really looking forward to getting up and doing some diving with you and Rachel over Summer.

Cheers

Nice going, Matt, the Azi CCR is looking good.
Helps to have a solid base to start from.
Why don't you place the link in the Links section,
someone is bound to look for info on a rig like yours
in the future.

MATTY, I also dive an Azimuth converted to MCCR, In fact my breather was originally intended for the military but fortunately ended in my garage.
IMHO it is a very well built unit altough I chose different ways from yours with my conversion. As I only dive down to 50 meters I never take extra bailout bottles and the original 4 liters bottle is enough. My oxygen cells are in my inhale lung which I consider more realistic reading to what I am breathing. Also the cells are R22s ( Yes !! I found a way to fit them through a P port !!!! ) as they last longer. Also why waste the unit original opv ? I injected my oxygen into the exhale lung by means of a modified drysuit inflator valve.

As to flooding, the unit can take a lot of water into the lungs without ending down into the cannister. It actually takes two cups dont forget that the connectors between the cannister and the lungs act as watertrap. Then there is the next water trap into the exhale chamber of the scrubber which is really well tought. I dont dive with an adv as I dont really think necessary. In fact I left the original add valve on the belt as I kept the original wing.
As you know if you wish to use trimix you have a ready made block with isolation valve of super quality. My electronics consist of a home made 3 sensor display in a lexan tube.

I have taken my unit to 4 hours in water temp of 23 - 24 degrees ( 2 hours each dive ) and by the coloring of the bone dry sorb 797 it cries for more but I will not risk more. Why did you state that your unit is very heavy ?? Mine is exactly 30Kg fully charged with sorb and i dont consider too heavy compared to other rebreathers. I have recently dived a classic inspiration and comparing the trim, weight and chest clustering I would stick with the Azi.

mine was an original mares unit with 300 bar 4 litre cylinders and all stainless steel scrubber. Later one had 200 bar tanks and I believe a different scrubber lid that reduced the weight.

As for the OPV, the original is great, but I wanted to use the original attachent point for the O2 injection, also I didn't feel that it couold be shut off enough and still realse enough gas in case of the dil 1st stage failure

Matt, great rig. The Azi is bullet proof. When turned into a mCCR, it makes for a dream rig... if you don't fly with it anywhere ! You'll have a lot of fun diving it.
Oh, by the way, thanks for the reference.

Your welcome, I would like to think I have mentioned everybody who ideas I used / borrowed somewhere to date in the blurb. Always wondered, what made you give up yours for a KISS? My intention really always has be to build and dive this unit for years. I can't see myself out growing the capability of the unit. Might look for a smaller unit (and it would be small, based on a coverted OMG C96 mCCR )for shallow diving (0 to 35 m) down the track, but not looking to replace this as such until it proves not to be able to do what I think it can.

30 kg of diving rig travelling domestic in the US and across the Atlantic with the family and outrageous excess luggage rate.
Going for the Classic Kiss was for the better anyway, except for the water traps that are less effective on the CK compared to the Azi.

I agree with Philippe, The Azi cannot be dismantled to save space. Alas I consider it to be a very good unit and very good looking too ( ITALIAN DESIGN ).
