The EAGLE CCR155 UBA is an electronically controlled, closed circuit, constant partial pressure of Oxygen (ppO2) mixed gas rebreather (CCR). It is designed to recirculate 100% of a diver’s respiratory gas and remove Carbon Dioxide (CO2) to result in a bubble free operation mode, apart from ascents and inadvertent gas release. The unit maintains a preselected ppO2 independent of depth. Oxygen addition is monitored and maintained by reliable analog circuitry enhanced by the inclusion of modern oxygen sensing technology. A selection of diluent gases may be utilised, depending on the depth requirements of the planned dive. Typically a nitrogen based diluent would be used for depths to 45 msw and a helium or Trimix-based diluent for deeper. The unit utilises two special spherical cylinders.
The EAGLE CCR155 UBA has two displays. The primary display is a Light Emitting Diode (LED) qualitative display in which each light corresponds to a particular segment of a meter. The secondary display is an analog quantitative display
in which each sensor output and the battery voltage can be observed by rotating the selector switch. The sensor readout is taken directly from the sensor and does not require electronic amplification.
The comprehensive IART training reflects the standards required by the manufacturer of the rebreather. IART is authorized by the manufacturer to conduct this training. The course manual was written in consultation with the manufacturer and you will receive the current edition from your IART Instructor.
The IART COLKAN EAGLE -CCR Level 1 course trains and certifies the user to dive safely within no-decompression limits to a maximum depth of 40m.
