| Recently I received very information about the adventures of the Russian diver Valery Mukhin. Valery achieved to build his own semiclosed rebreather based on a IDA 59 ! Here you find his story. | ||||
|
Dear Mr. Jan Willem Bech; I would like to tell you about my experience as a homebuilder rebreather. I have got a IDA-59M one year ago. I have altered this rebreather to a SCR which I named IDA-59SCR. I have made some dives with IDA-59SCR in the beginning of May of this year. (2004) The work to transform the IDA-59M to a IDA-59SCR had some stages. It is reflected in section of my site devoted to this work: http://mukhin.vif2.ru/diving/IDA-59SCR.HTM Unfortunately all site only in Russian. So I shall give a brief retelling.
|
||||
| Stage 1. I simply
studied a design of the device and the operation manual.
|
||||
 |
||||
 |
||||
 |
||||
| You can find the link to the IDA59 manual on the download page (in Russian only!) | ||||
Stage 2. I have established DIN sockets on cylinders
IDA-59M. In these sockets I have established regulators: |
||||
 |
||||
 |
||||
In the scrubber I used a limy absorber instead of the original substance called "O3". Instead of trimix I used air. With an additional hose I have added the oxygen gauge. |
||||
 |
||||
 |
||||
I have tested the rebuild device in a pool: |
||||
 |
||||
Tests have shown the non stable contents of oxygen in an inhaled mix in such configuration. Therefore I have made the decision on alteration IDA-59M in SCR. |
||||
| Stage 3. IDA-59SCR
From IDA-59M I have left only a scrubber and counterlung: |
||||
 |
||||
I have connected two sockets to counterlung. I have established nozzle from Dolphin rebreather in one of which: |
||||
 |
||||
 |
||||
 |
||||
 |
||||
The Nitrox is carried in cylinders mounted on the BCD: |

||||
 |
||||
| I would like to thank Valery Mukhin for
sending me these pictures of his homemade rig from Russia! Dive Save and Silent, regards; Janwillem Bech |
