Hi all,

yesterday, with a friend aslo with a Meg, we dived in a 14°C water during 175 min.

Back to the cars, we both open our canisters and find, looking at it, the upper part of the sorb wet (half of the canister).
There was nothing at the bottom of the scrubber.

It is looking like only condensation. Sorry, I couldn't shoot it, but I'll try next time.

We both dived with 1 - 2,5 sorb. Maybe phenomena is less visible with bigger granulometry.

Sure there is no leak on my meg, only condensation.
But I don't like that too much. What about efficiency of wet sorb ?

Cheers,

Frank.

the sorb needs moisture for the chemical reaction.. as long as the sorb isnt turning to mush everything should be fine.. If I remember my numbers correct there needs to be something like a minimum of 20% moisture content for the ideal reaction, as this number drops so does the scrubber efficiiency...
