IDA-59

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

• • 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

• • 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).

Tiina with an IDA 59

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.

Tiina ready to GO !

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.
