    Scrubber temperature

    Can anyone tell me what the temperature range of sorb is?

    I am mainly interested in water temps 14-22deg C but other water temps would be of interest as well.

    Can this information be seen during pr post dive on the rEvo RMS or any other temp stick system?

    you can see it best at the end of the dive, when back in surface mode
    go to SCRUBBERS/TEMPERATURE and you see the complete profile

    it varies, depends on a lot of factors

    in general, during diving, normal depths, the scrubber, when fully warm, warms up the incoming gas by 20-25°C
    temp of the incoming gas depends on water temp, depth, breathing rate, type of gas, rebreather design, etc etc etc

    Re: Scrubber temperature

    I found this old thread, and as was tinkering with the graphical representation of data from tempstick during the dive, i will show you an image. Maybe for the future generations :D It was a 100 minutes dive, something to 35m deep, bottom temperature around 7 degrees Celsius, temperature from the 55 minutes to end in shallow depth of 7 meters was 23 degrees Celsius. The top of the graph is at the end of the dive in the shallow water. The srubber was not fresh as you can see the rapid move of the reaction front during the first 10 minutes (about 2:30 hours on it previous day).
