Inspiration O2 injection

After a dive with my YBOD with HH I notice a considerable amount of moisture on my cells and if I do not dry them in between dive I notice a significant change on how the cells read. I've been putting some thought of how to combat this problem and I've come up with a couple of ideals (none of them original BTW) and would like to get some thoughts and opinions before I invest any time or money.

I think most of the moisture created in the head is caused from the O2 which is at ambient temperature being injected very quickly into a warm environment. My first ideal involves replacing the black rod which goes thru the canister that holds the soda lime with one that is hollow all the way thru. Then I was thinking of having the solenoid connect to the rod so the O2 would be injected at the bottom of the stack. One of the possible problem I could see is the possibility of CO2 leaking by but it shouldn't be a problem as long as I could come up with a sure way to connect the solenoid to the rod. Other than that does anyone see anymore potential problems? This is the way the Optima injects O2 into there Rebreather and there does not seems to be any disadvantage to it


2. I've noticed with the HH the moisture will form in different locations depending on how the sensor plate is postioned. If the plate is postioned over the injection point then the moisture seems to collect in upper area of the head. If I where put some sort of aborbant cloth in that area I think if would collect a lot of the excess moisture. Would there be any issue I should be concerned with if I tried this?

Thanks,

You can easily test this. You could switch off the HH solenoid control (put it in manual mode) and run the unit completely manual. This way all O2 goes through the scrubber first. If the head has less condensation then you are on the right track.

Good ideal I'll try that.
