[PSUBS-MAILIST] scrubber design

[hank pronk via Personal_Submersibles]

 I check the performance exactly the way Rick described, I put the meter at the discharge and watch the number plummet.  Usually by the time I get organized to do a test the CO2 is at 2500 PPM in the sub.  If the scrubber is working well the number will drop real fast at the discharge.  Hank

All,

  

A simple way to indicate scrubber performance is to measure the delta Temperature between the in- and outlet.

Further,  The general working of the LSS is depending on the ambient temperature, air circulation and fear/exitement of the passengers..

River,

I was thinking that the large fan on Gamma's scrubber was increasing exposure do to increased volume.  It is weird, it obviously worked well for many years and dives with two occupants.  I went with the computer fan driven scrubbers instead of restoring the original scrubber because the original was very loud.
