John,
From my limited knowledge, by far the best system for
removing CO2 from the loop is cryogenically. Don't ask
me details how it works, but it freezes the CO2 out,
leaving "snow". Another advantage is using the same system,
O2 can be added to the loop predictably, by "boiling"
off to maintain it's PO2. All this can be controlled with
simple temp gauges, no solenoids or sensors are necessary.
Oh, and something else, it works, and is used by commercial
divers in the Nth Sea. They use it as a gas reclaim
system.
maybe someone with a good understanding of gases could explain
how this system works?
Regards Rod Nairne.
