[PSUBS-MAILIST] scrubber performance

[Alan James]

Jon & Hank,
thanks Jon, that is very encouraging. 
Hank, I was hoping you wouldn't ask me that.
I looked up ABS rules & they say " the concentration of CO2 will never exceed 0.5 percent by volume.
I work that out to be 5,000ppm so you are sweet.
There is a good article on life support on the Psub site by DR Phil Nuytten. This discusses CO2 levels,
Alan

Hank,
 
Is normal, The CO2 level
must rise first before the scrubber warms up and starts to work. In cold
weather it will take longer and you may consider electrical preheating.
2300 PPM / 0,23 % is a
good figure anyway! 
 
Regards, Emile

scrubber performance
 
Is
it normal for a scrubber's performance to improve after 15 min or so.  My
scrubber is maintaining the sub at  2,300 ppm  but started much
higher like 3,500 ppm.   Is 2,300 ppm on the high side? 
Hank
