Diving the Inspiration to greater depths brings the problem of gas management. Extra bottles are needed for deeper dives. This is why the Normoxic and Trimix Inspiration divers take side bottles. This bottles are filled with a gas for leaving the bottom to reach a decompression depth. Then there is a switch to the other gas in the second side bottle. Taking these side bottles is a rather heavy job and people started looking for other solutions. One of them was found in the construction by Jan Jørgenson called the “JAN BOX”. It consists of a frame with the possibility to mount the bailout gas and the deco gas in one frame carried on the back. Kim Heigren dives his rebreather in this way and sent me some pictures of his configuration. He carries a 3 liter diluent cylinder and Bottom mix 7 ltr TX 16/52 on the left, and pure oxygen with EAN 50 on the right. Also he prepared hoses to connect the bailout cylinders to the counter lungs to achieve an SCR possibility. Both first stages of the 3 litres are equipped with an overpressure valve.

And here are some additional pictures I received from JJ Technique, thanks guys!
Therebreathersite was founded by Jan Willem Bech in 1999. After a diving career of many years, he decided to start technical diving in 1999. He immediately noticed that at that time there was almost no website that contained the history of closed breathing systems. The start for the website led to a huge collection that offered about 1,300 pages of information until 2019. In 2019, a fresh start was made with the website now freely available online for everyone. Therebreathersite is a source of information for divers, researchers, technicians and students. I hope you enjoy browsing the content!
