Someone told me it was in use with Russian tank crews. Doesn’t sound to bad..

 De IDA-76 is een uiterst merkwaardige rebreather. Het doel van deze rebreather is tot op heden in Europese kringen nog niet bekend. Wel is duidelijk dat de gashuishouding tot iets zeer speciaals behoord. De zuurstofcilinder is in cascade vorm gebouwd, iets wat tot op heden bij geen enkele andere rebreather is aangetroffen. Ook van de voorganger IDA 75 is vrijwel niets bekend.

 

Additional information received from Mr. Anders Puranen from Sweden:

I have found out some more on the IDA76.

According to the manual the volume of the mine cylinders are a total of 0.45l, the operating pressure is 150bar(Although I have used and dropped mine on the floor when it was filled to 200bar...)

The scrubber is to be used with 'O3' for all kinds of diving. The O2-producing efficiency of the 'O3' is highly dependent on the water temperature and a scrubber temperatur of 50-60 C is needed to get the reactions going as intended.

The unit is to be used on pure O2 down to 20m (!) and 50% nitrox is used for diving in the 20-40m range(!!). The duration is 15 min at 40m.

So this unit is pretty much limited by is small gas volume, but it can always be modified...
