Hello!

I remember that the Swedish Defence Research Establishment (FOI) had a
student at my university to bulid such a device as a M Sc thisis. This was some fifteen years ago. The base was an existing closed loop breathing simulator that was extedid with a catalytic converter (from a petrol car) and
a system for incjeting Propen (C2H4) into the catalytic converter. Some heat exchangers was allso a part of the system. Both for heating at start and cooling once the combustion was up and running.

In principle this was a device that added heat, CO2 and humidity to the loop while extracting O2. I dont know if the apparatus is in use any more.

Regards!

Hej Sten

I suspect that we are talking about the same guy, AFAIK from talking to him and guys using this test rig a slightly modified version of that setup is still in use.

Ps
My latest D5-modifications worked flawlessly on two boatdives today, very nice!
