Hi all,
I have just been reading the doc from Dräger discussing the scrubber time increase from 70 mins to 110 mins of the Ray scrubber. I have put it in the resources section of my site for reference.
Now this shows that under normal levels of exertion a recreational diver would have to handle with, the scubber duration goes to 110 mins, but this is in water at -2°C !!!
Myself I would pretty much never have to deal with water under 16°C even in the midst of winter so how will that affect the scrubber performance? Does anyone know of any test run on this?

Basically the test data is as follows:
If the physical work is reduced to the following test criteria:
- water bath temperature : 4 (-2)°C
- breathing rate : 20 strokes/min. x 1.5 L/stroke = 30 L/min.
BTPS*
- simulated oxygen consumption : 1.33 L/min. STPD**
- interruption criterion : 0.5 % by vol. CO2 in the inhaled gas
- CO2 supply : 1.2 L/min. STPD**
the CO2 absorption increases from 70 minutes to 110 minutes.
