X-CCR is an expedition grade rebreather
designed to provide reliable performance in demanding underwater environments.
The unit is developed using years of our experience in CCR development with respect to the needs of divers and explorers.

X-CCR combines a well proven rebreather chassis with the most innovative electronics package
to form the most fault tolerant rebreather, provides outstanding reliability, ruggedness and yet the easiest maintenance.
The most important feature of X-CCR is reliability, flexibility, durability and user-friendly design.

X-CCR has been design to cope mechanical, electronic and human failures without locking you out and leaving you without the ability to complete your dive.

X-CCR Head

Industry unique Quick Bayonet Lock on the head, with easy access to the O-ring.
The head is designed to have advanced air flow paths to eliminate condensation able to form on the O2 cells.

The Shearwater SOLO board in the head serves reading from three O2-sensors, solenoid firing, CO2-reading, HP reading on Oxygen and Diluent tanks, Head-Up Display control. If the user cuts any cable, the unit will still carry on working and maintain the PPO2 up to surfacing.

The X-CCR unit is standardly equipped with Shearwater DiveCAN Petrel2 Controller on the left hand and with DiveCAN Head-Up Display placed on the BOV.
Optionally can be added DiveCAN or analog Petrel2 Monitor (as a secondary computer) and/or DiveCAN or analog NERD.
The head is equipped with 3 specially developed watertight connector, rated up to 300m (made of AISI 316) allowing very flexible connection of the devices. All three connectors provide DiveCAN bus, while one of them provides DiveCAN as well as auxiliar analog bus.
See the connection diagram below

Connection diagram

HP sensors are located on the top of the head, connected via HP hose ... no cables, wireless or optical links to fail.
The Shearwater electronics has very low power consumption and provides long term battery life.

O2-sensors and built-in CO2 sensor are placed in the easily removable cartridge making it easy to dry up, check or replace the sensors. PPO2 readings are electronically separated one from another, in the event of a short circuit on any sensor or cable or one of the computers, this will not affect the ppO2 reading on the other computer. On the head there are two independent replaceable Li-Ion batteries 18650, located in the sealed compartments out of the breathing loop, so the breathing gas can not be contaminated in any case. One battery supply solenoid firing, while the second battery supply DiveCAN Head-Up Display. DiveCAN Petrel2 Controller has its own battery AA with ca. 100 hours of operating time. Secondary ppO2 monitor device (DiveCAN or analog Petrel2 or any other analog ppO2 monitor) has its own battery. You never have to miss a dive due to battery problems.

User serviceable low power Solenoid of AISI 316 Stainless steel rated for up to 17 bar (no pressure setting of the 1st stage needed), with swivel fitting with built-in O2-filter.
