Scrubber Unit

The Standard scrubber unit is of axial type and holds 2,3 kg sodalime (sofnolime 797). The scrubber unit is easy to lift out of the canister as the attached lid has a lifting handle on top. The scrubber is attached to the lid by a heavy duty thread.

The construction of the scrubber, lid and canister makes Re-packing of scrubber as well as surface interval maintenance an easy task!

Test parameter:

 

40l/min air, 1.6l/min CO2,

4°C water temperature

     

Used diluent:

 

40 m - Air

100 m - Trimix 11/65

     

Soda lime

 

The only supported soda lime is: Sofnolime® 797 manufactured by Molecular
Products.

     

Oxygen Cylinder

 

3 Liter steel cylinder (200 bar)

     

Diluent Cylinder

 

3 Liter steel cylinder (200 bar)

     

On board gas duration

 

Oxygen: The on board oxygen supply will last 252 minutes, if the diver consumes

1.78 liter of oxygen per minute.

3 liter x 200 bar = 600 liter - 25% reserve = 450 liter

Diluent: The duration depends on the depth and activity of the diver.

3 liter x 200 bar = 600 liter

     

Batteries

 

2 x 3.6v lithium (SAFT 14500). One battery for the
controller and one battery for the HUD.

2 x 9v block lithium
(Parallel operation for the solenoid)

     

Volume of the counter lungs

 

8 litres

     

Maximum application depth

 

Max. 40 m with air as diluent
Max. 100 m with trimix as diluent

Warning:
Dives exceeding a depth of 100 m are associated with numerous additional risks

>99.5% (medicinal oxygen)

Helium:

 

>99.996

     

Atmospheric pressure range

 

800 - 1050mbar

Essential features of the JJ-CCR Rebreather:

  • Highly robust aluminium housing to which it is possible to secure up to 4
    diving tanks (2 - 12 litre) using conventional tank belts.
  • Self-filling soda lime canister (axial or optionally additionally radial)
  • Heavy duty stand
  • Integrated handle
  • Back-mounted counter lungs
  • Redundant power supply: One battery for the controller,
    one battery for the HUD and two parallel batteries for the
    solenoid. None of the batteries are integrated into the loop.
  • Integrated ADV (Automatic Diluent Valve)
  • DSV (Dive Surface Valve)
  • Valve for manual oxygen feeding with the option of feeding in external
    gases - also optional for the diluent
  • Independent Digital HUD (Head Up Display) with real-time display of PPO2
    for all three oxygen sensors
  • Reliable controller with an integrated multi-gas decompression
    computer (based on the Shearwater Petrel)
  • Supplemental manual diluent inflation (JJ-CCR Rebreather DiveCAN - CE Edition)
  • Diiuent inline shut-off valve (JJ-CCR Rebreather DiveCAN - CE Edition)
