jj-ccr logo


The JJ-CCR is equipped with a Shearwater Petrel controller, which contains a multi-gas (nitrox, trimix, heliox) and multi-mode (OC and CC) decompression computer. The firmware installed on the controller is optimized for the JJ-CCR Rebreather and contains capabilities and functions developed specially for the equipment. The Shearwater Petrel has a 2.4" Full Colour HD Display. The controller does only have two buttons and a logical menu for rapid operations.

Accepted battery types:
The controller can accept a wide variety of AA sized batteries. The controller can accept any AA sized (or 14500 size) battery that outputs a voltage between 0.9V and 4.3V. JJ-CCR ApS strictly recommends to use only a SAFT 14500 LS 14500 battery for the controller.

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


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




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

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

Oxygen control


Two oxygen setpoints (low and high). Can be switched
as many times as required, also changeable under water.


Oxygen setpoint range


From 0.4 to 1.5 bar (low and high)


Oxygen warnings




0.4 bar



1.6 bar


Oxygen sensors


3 galvanic cells (type: R17JJ-CCR)


Operating temperatures


When diving:


+4°C to +34°C

Short-term (air):


-10°C to +50°C

Long-term (storage):


+5°C to +20°C


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)
