Seaway has introduced there new Cora II rebreather. Long
before the latest presentation Airway Introduced the CO.RA I. Both Cora
units are semiclosed lung operated units. In German they are called "verbrauchsgesteuert".
The simple concept of this rebreather has some nice features but above all
the most surprising factor is the price. The unit is sold for 1800 euro!
Unfortunately there is no CE marking now. The rebreather was
introduced in 2006 on Boot Germany.
2007 the unit was on Boot again and looked much better now! (Technically
not much changed however). Also they showed a new model with the scrubber
mounted parallel to the shoulders. That model will be published later. Let's
have a quick look at the CORA I and a more detailed look at the 1800,00 euro
Seaway CORA II
The CORA II is designed in such way that by interchanging
the lids the function of the rebreather can be changed. Now the unit is
available in 4 versions:
-Semiclosed lung operated rebreather with the use of 1 Gas
-Semiclosed lung operated rebreathers with the use of two
gases (CMF flow)
-MCCR, closed circuit with manual addition and constant mass
flow of 0,8 ltr/min (Kiss style)
-ECCR, electronic controlled closed circuit rebreather (to
CO.RA I made by Airway
A huge mouthpiece conform the 1997 standards ;))
Over the shoulder counter lungs. Extremely
Mouthpiece with shut off valve
The scrubber has been placed in a stainless
steel housing made of V4A (1.4571)
Each unit comes with engraved serial numbers
The scrubber inside the housing is placed
asymmetrical, in such way it is impossible to connect inhalation and
exhalation tubes in the wrong way.
The Lid can easily be opened
Gas addition on top of the scrubber
Although the gas enters the scrubber in
radial direction, the actual scrubbing finds place in axial direction! The
scrubber contains maximal 3,5 kg sofnolime.
The housing has extra thermal isolation to
prevent the scrubber of cooling in cold water.
