Highlights of the Russian Navy Rebreather IDA-59 M

    • fully closed rebreather

    • originally used as bailout system for submarines from a maximum depth of 300 meters and for exercising light underwaterwork down to 90 meters.

    • works with trimix and pure oxygen

    • gases are stored in 2 seperate 1 liter tanks

    • one scrubber canister

    • continous-flow method for pure oxygen

    • 4 depth ranges for different continous-flow rates ( 0-20 meters;20-37 meters;37-55 meter; >60 meter no continous-flow anymore)

    • continous-flow rate changes automatically at 3 different depths

    • different continous-flow rates when either descending or ascending

    • pure mechanical apparatus (no batteries,no electronics)

    • maximum depth: 90 meter (for greater depth an additional helium-tank must be connected)

    • maximum divetime approx. 2.5 hours when exercising light work

    • weight is 15kg with filled scrubbercanister

    • scrubber material can be DRAEGERSORB or SOFNOLIME

    • comes with a fullface-mask

The IDA 59 System

IDA 59 System
    • The upper part is the counterlung (behind the fullface mask)

    • The leftmost tank contains the trimix or another breathable mix

    • The rightmost blue tank contains pure oxygen tank (a regulator and the constant mass flow valve is attached

    • The blue part in the middle is the scrubber canister

The IDA 59 Counterlung

IDA 59 Counterlung
    • Here you see the counterlung with the adjustable overpressure valve on the right side

    • The counterlung is made of rubber,which makes a kind of bulletproof impression

    • The counterlung is worn around the neck like the antique bouyancy-compensators

    • In the middle,you can see the mouthpiece with the shutter (a normal regulator mouth piece is here used instead of the original fullfacemask)

IDA 59 Tanks & Scrubber Canister

    • Left side: 1 Liter steel tank used for oxygen with regulator,valve and constant mass flow valve attached

    • Middle: Scrubber canister

    • Right side: 1 Liter steel tank used for trimix with valve and regulator attached

IDA 59 O2-Tank,Regulator,Constant Mass Flow Valve

Here you see the oxygentank with the regulator and the CMF valve.The CMF valve changes the flowrate at 4 different depths (the flowrates are also changed different, depending on ascending or descending).

Here you see Tiina wearing the unit in their original way,exept that a ordinary regulator mouthpiece is used instead of the fullface mask

Tiina, the IDA-59 and the Rec-Rig

Tiina uses a normal recreational rig in conjunction with the IDA 59 for infalting the BC,the drysuit and as a kind of bailout system.

This is the front view of Tiina using the IDA 59 together with the rec-rig.From this picture you can see, how easy it is to reach all neccessary components when diving.
