Chapter 1: Technical Specifications
1.1 Limitations of use:
→
This unit is intended to be used by trained people only.
→
The use of the unit is only allowed when an independent alternative gas
source is carried at all time by the diver, that can be used at any time during
the dive, and that has enough capacity to safely end the dive in case of
malfunctioning of the unit.
→
Only oxygen compatible grease like
Tribolube 71
should be used anywhere
in the unit.
→
Max certification depth: 40m with diluent air.
→
Max certification depth with trimix or heliox, and PPN2 <= 4.0 bars: 80m
(mCCR) / 100m (hCCR)
→
Temperature conditions during use: water temperature minimum 4° Celsius,
maximum 34° Celsius.
→
Scrubber endurance: at 40m depth, 4° Celsius, CO2 production of 1.6l/min
STPD, 40 RMV (2liter tidal volume), using 2.7kg
Sofnolime 797
: time until
the PPCO2 of the inhaled gas reaches 5mbar: >160 minutes. Time until
the PPCO2 of the inhaled gas reaches 10mbar: >170 minutes.
→
Scrubber endurance: at constant depth of 100m, 4° Celsius, CO2
production of 1.6l/min STPD, 40 RMV (2liter tidal volume), using 2.7kg
Sofnolime 797, using any trimix or heliox (PPN2 <= 4.0 bars): time until the
PPCO2 of the inhaled gas reaches 5mbar: >75 minutes. Time until the
PPCO2 of the inhaled gas reaches 10mbar: >85 minutes.
→
Max work rate conditions: 75 RMV at 40m depth, CO2 production of 3l/min
during 5 minutes.

vertical position.
→
