  • Submatix CCR
    adjust to personal metabolism Close up of needle valve and bypass valve This year the Submatix 2003 was introduced Uwe Lessmann presents a homebuilt rebreather for his recreational dives Apart from the breathing hoses there are no longer Dräger parts used All parts of this rebreather are designed by Uwe The Submatix rebreather is a very compact and lightweight rig Fully prepared for diving the unit weights just 15 kg

  • OxyEye Controller
    70 ATA the Setpoint between 1 30 and 1 60 ATA enabling the setup menu holding pressed both buttons after the welcome screen like fig 2 Fig 2 Fig 3 In fig 3 is shown the calibration menu that appear after the PPO2 limits setup On the bottom row are shown the sensors voltages in millivolt This allow to verify the stability of the reference mix gas in the loop and the goodness of the sensors it selves Anyway the calibration routine will exclude the sensors with a poor voltage marking them with the X sign on the right side of top row Moreover it will exclude also the unconnected sensors marking them with the dash sign The calibrated sensor will be indicated by the star sign Excluded sensors of course will not be considered in the average calculation like shown on fig 4 Fig 4 Fig 5 In fig 5 is shown how can you choose the reference gas for calibration either air or oxygen It is not possible the casual activation of setup and calibration menus but is possible if wanted to change of PPO2 limits on flight A serious danger like low PPO2 value will be indicated by a fixed red light like shown on fig 6 Fig 6 Fig 7 On fig 7 is shown the blinking green light because PPO2 is over PPO2min but under Setpoint PPO2 0 20 ATA Notice in the dark picture the backlighted LCD On fig 8 is shown the complete system installed on the head of the EDI2002 Semiclosed Rebreather where are located the 9 Volts battery and two Teledyne R 22D sensors Fig 8 The red molex plug connects the third sensor not installed here to the HS Eng dive computer The OxyEye cabinet was built from a block

  • Wing for Kiss Rebreather
    diver has as far as trim and buoyancy are concerned It is why this wing features height adjustable slots to put it on the Kiss shell back plate Considering that some of us also teach OC and or dive singles up to 15 litres or small doubles 2x7 litres or 2x9litres the wing also features 2 sets of grommets that are useful for these configurations The result is a very a versatile and polyvalent wing that will suit a lot of different needs When designing it I kept in mind that a rebreather diver must be able to access the inverted tank valves at any moment both out of the water and at depth with the wing partially or completely inflated The sides are slim and start close to the back plate When at depth the wing does not over wrap the tanks completely and leave easy access to the valves The result is a streamlined rebreather diver and good hydro dynamic qualities A RB diver also pays attention to the volume of upper part of the wing so it does not interfere with the breathing hoses and leave room for the loop This is the case with this wing

  • Kiss the Hammerhead
    first test dives were made Finally the result matched most peoples opinion and in autumn 2004 the HH electronics were delivered by Kevin In a big box the HH including the head both hand sets and the DIVA my HH finally reached my home With a few parts from Swagelok hoses and connectors I could start to install the HH The biggest problem was the installation of the oxygen sensors to the HH The connection from the sensors to the head is made by two wires with small banana plugs The banana plugs and the sensors interfere and the head can not be placed correctly on the KISS The banana plugs break easily when bended so I took another way to make it fit I cut off the label of the oxygen sensors and took off the upper part and finally there was enough place for the banana plugs and the sensors The head could now be installed as it should be As there are many different possible positions for the solenoid I choose to install the solenoid inside the counterlung housing at the bottom The solenoid is protected very well and the counterlung is not affected by the solenoid The wire to the head is long enough and runs inside the counterlung housing The solenoid is held by two small screws The solenoid is then connected to the oxygen inlet which was changed from the 90 elbow into a Swagelok T with a Swagelok hose The oxygen inlet to the solenoid is a short Swagelok hose which comes from the first stage The first stage feeds the KISS valve as well as the solenoid The KISS valve can be shut off from the oxygen supply by a Swagelok shut off valve This meets my actual needs In future I

  • Untitled 1
    on 1 3 by frequently adding a little oxygen manually each 10 15 minutes When he works a little harder he will see that the setpoint slowly drops and he needs to manually add some extra oxygen By just pressing the button for a second he adds a little oxygen until his readout is 1 3 bar again OK now how long are you able to dive this system When we do not count CNS values in this example we can use the system extremely long Imagine the diver takes a 5 liter bottle filled with 100 oxygen 200 bar He has 5 x 200 1000 liter oxygen When using 0 8 liter per minute he can dive 1000 0 8 1250 minutes more then 20 hours The scrubber decompression obligation and CNS limits will force him to leave much earlier Dive times of 3 hours are realistic although the diver has to carry a lot of bailout gas How deep can we dive using a MCCR The rebreather based on manually addition has no depth limit Point is that the gas flow will stop at a certain depth but oxygen can always be added manually Of course the pressure from the first stage regulator has to be higher than the ambient pressure When using an IP of 14 bar to the CMF valve the possibility of gas addition stops at 130 meters The CMF valve itself has technical specifications These specifications are related to many parameters but the main factor is that the valve needs to be pressurised with a fixed pressure that is not changing with the depth So you need to modify the first stage that feeds the CMF valve You need to modify the first stage in such a way that the pressure is constant not changing with depth In the valve there is a very small hole for example 0 08 mm that gives a constant mass flow when the pressure on the supply side is double minimal compared to the ambient pressure So when we want this 0 8 bar flow at 60 meter we need an intermediate pressure of 14 bar To calculate the exact flow through the nozzle I have found the formulas which are available through This page Another page can be found here What happens when we go deeper The flow decreases very slowly in the beginning and the diver has to add oxygen manually more often When the ambient pressure is near the IP pressure absolute the flow will fall and finally stop On this page you will find detailed information about the flow behaviour Most important when using a MCCR is being able to calibrate the oxygen flow and to measure the pO 2 in real time Using only one cell is commonly accepted as not smart Using two cells for measuring the pO 2 is better but using three cells offers voting logic and the bad cell can be recognised It is most important to use this

  • Computers and Rebreathers
    document worden bekekeken Document pdf Meer info zie link VR3 bedankt Rob Bakker Click for the big picture Just had a sneak preview of Kevin Gurrs new VR2 anybody looking for a OC SCR CCR that just does nitrox you can set up to four gasses this is for you its really nice looking with all the VR3 features except trimix in a nice new housing Expected retail is not yet decided Voor de SCR markt is een dergelijk systeem al wat langer voorhanden Zowel het Zwitserse UWATEC als Amerikaanse Cochran maken voor deze toepassingen een computer De UWATEC Oxy 2 in combinatie met de Aladdin Air Z O2 vormen een fantastische combinatie voor o a de Ray en de Dolphin In de Cis Lunar MK5 is de decompressie computer ingebouwd Dit is een bijzonder aspect van de Cis Lunar MK5 omdat geen enkele andere rebreather een dergelijk optie heeft Nu mag dit ook wel gezien de prijs van de Cis Lunar 17 500 dollar 19 173 Reken voor een Nexus eens 550 euro of voor een VR3 2495 dan is dit samen met bijvoorbeeld de inspiration toch nog een aardig stuk goedkoper De Cis Lunar heeft wel automatische diluent toevoeging maar ja je kan niet alles hebben Cochran heeft een bril in het programma die aan hun computer te koppelen is Op deze wijze wordt een HUD head up display gerealiseerd Deze HUD is standaard op de Cis Lunar Enkele gebruikers van de Inspiration hebben ook al HUD ontwerpen gemaakt en er zijn inmiddels al sommige uitvoeringen te koop Wet PC underwater computer inclusief HEAD UP DISPLAY De huidige generatie computers kunnen vrijwel allemaal via een seriële poort aan een pc worden verbonden Op deze wijze is het mogelijk de data van een gemaakte duik te downloaden naar de
