Why the X-CCR Rebreather?

The X-CCR rebreather is built for extreme expeditions, combining user-friendliness with cutting-edge technology.

The unit is rated to 100 metres, with it being tested to 150 metres during the manufacturing process. It’s built by iQsub in the Czech Republic and distributed by SubGravity in Utah, USA, and is the result of many years of testing and exploration.

The X-CCR rebreather is the unit of choice of many industry-leading explorers, providing reliability and robustness, with easy maintenance. 

Aside from the advantages that all rebreathers offer, there are some special features that make the X-CCR rebreather stand out.

X-CCR Rebreather Features

Let’s take a look at the X-CCR rebreather’s main features.

Radial ScrubberDuration of up to 6 hours at depths of up to 150 metres, with very low flow resistance
Integrated Shearwater TechnologySupporting 5 CC and 5 OC gases, Bühlmann + GF algorithm with optional VPM-B algorithm, no lock-out mode, CNS monitoring, two PPO2 set points with optional automatic switching, firmware updates downloadable, integrated tilted compass
DiveCAN® digital communication electronics system with Head-Up Display (HUD)Robust error-resistant communications, parts can easily be swapped out for repairs and travel, modular design increases redundancy of individual parts
Back or front mounted counter lungsConfigurable for diver preference
Breathing hoses made of EPDM rubberVery UV, salt and grease resistant
Quick Bayonet Lock system on headIndustry unique, provides quick access to the O-ring
Oxygen and diluent tanks between 2-7L can be mountedConfigurable for diver preference
Solenoid and Oxygen electronics (SOLO) boardManages PPO2 via 3 O2 sensors, monitors CO2, monitors battery life, failure-tolerant modular system (continues to manage PP02 in the event of short circuits or communication failures)
Two Li-Ion Lithium Batteries 18650Independent and redundant, located outside the breathing loop to prevent contamination
Bailout Valve (BOV) ShrimpMaking for easy switching to open circuit in bailout scenario 

Standout Features of the X-CCR Rebreather

The Quick Bayonet Lock System is a handy feature of the X-CCR rebreather that makes construction and deconstruction of the unit so much easier.

On top of this, the removable sensor cartridges can easily be taken out between dives, allowing for quick drying.

Similarly, the high pressure hoses feed directly into the unit’s head, meaning no more dangling SPG hoses – streamlining the X-CCR further!

Lastly, the multi-outlet oxygen and diluent manifolds allow out-board gases (i.e. bailout gases and oxygen if carried) to be connected directly via the Swagelok QC6 system. This means that in the event that you run out of on-board diluent or oxygen, you can simply connect your off-board gases, allowing you to continue to perform diluent flushes, maintain your PPO2 in the loop, as well as many other life-saving functions. This is where the X-CCR rebreather truly supports the exploration diver.
