Re: [PSUBS-MAILIST] Life Support (O2)



Harry -
 
Medical oxygen is bone dry.  O2 in the lines will accelerate oxidation (rusting) if humidity is present.
 
I may install a dehumidifier in Magical Child.  In the long run, the idea of rubbing anti-fog all over my canopy doesn't really appeal to me.
 
Because my sub will be an ambient, one way I'll be reducing humidity in the cockpit is by venting my breathing exhaust directly out of the cabin.  Perspiration and water vapour from my latte (seriously) will be the only sources of humidity in the boat.
 
Initially a towel and anti-fog will do. 
 
Hope this helps.
 
 
Rick L
