Title: Liquid O2 ?
Post by tony-PA on Apr 13^th, 2008, 3:37pm

ciao eveybody ;),
any difference between O2 gas and the liquid one (for CHers users) ?
Thanks for answers and suggestions;
PF days (....years) to all of us :)

They are the same -- unless you try and drink the liquid form!

No difference. It takes less space for the storage tank. Then gets converted to GOX for breathing.

My first med supply company (the one that didn't know what a non-rebreather mask was) tried to tell me it was more pure than the 100% GOX. But the units they had would only deliver at 6 LPM.

Hmmm, drink it up and it would be available anytime, just burp!

You get the same oxygen from a Liquid Oxygen (LOX) vacuum dewar flask type delivery system as you do from a Gaseous Oxygen (GOX) cylinder. The fill sites that recharge your O2 cylinders do so from a very large LOX cylinder...

Other than the cost of the hardware, the only real difference between LOX and GOX home delivery systems is the LOX storage vacuum dewar flask and portable converter you carry around that boils off GOX from the LOX and delivers it to a constant flow regulator. As liquid oxygen is maintained at -297.3°F it requires a lot of heat energy to convert/boil off LOX from a liquid into oxygen gas. This limits the flow rate to around 15 liters/minute. Trying to get higher flow rates will cause a LOX type converter system to "Freeze up" without adding a very expensive electrical heat exchanger. It expands at a ratio of 1 to 860

Nearly all the jets I flew had removable 10 liter LOX converters.

Take care,
