SF2 ECCR OPERATION MANUAL
2.5 Endurance time SF2 Scrubber
According to the soda lime manufacturer, 1 kg of soda lime can bind approx. 110-
150 l of CO2. The approximate lime time can now be calculated using the
metabolism. The scrubber of the SF2 can hold up to 2.2 kg. The theoretical CO2
absorption capacity is about 330 l CO2. (2.2 x 150). Normally, one produces with 1-
1.5 l / min oxygen consumption or CO2 production, corresponding to physical activity
of about 100 watts. That means the theoretical lime filtering time is about 3.5 hours
(330 / 1.5 = 220 min).
CAUTION
The lime shouldn't under normal conditions Be used for more than
three hours. This is true both for repetitive dives as well as for single
dives corridors.
WARNING
Under extreme conditions, the lime Enormous service life. As part
of the CE test, the Lime at 50 meters ambient pressure, one
Water temperature of 4 ° Celsius and one Breathing minute
volume of 40 liters per minute tested: the lime service life is reduced
under these conditions on 60 minutes:
