Hi
The gases used as diluents stay as gased down to very low tempeatures so 
this won't be a problem. The real problem is the CO2 absorber. Ordinary 
absorbers gets inefficient at low temperatures, so the useful life of the 
absorber gets critical. Generally the gas supply is not a problem in 
rebreathers. In a normal oxygene rebreather for military use the absorber 
box is larger than the O2 tank.
