Submatix a German manufacturer from Erfurt has been marketing rebreathers since 2003. Over the past almost 20 years, they have brought a wide range of products to the market. The SCR100 line was followed by the Quantum-line and side-mounted rebreathers. Also a nice combined oxygen and ECCR has been added to the assortment. This page gives an impression of the developments but the most recent information can be found on the Submatix website.
Submatix SCR 100 XT
Here you find a description of the Submatix SCR 100 XT SC rebreather developed by Uwe Lessmann. The Submatix rebreather is a semi-closed rebreather with a dual gas supply. There are several new aspects realised in the design. The gas flow of each mix can be adjusted by means of a needle valve. This makes the unit suitable for the use of different gasses. De rebreather is equipped with a patented MPSS gas switch block which makes it possible to switch gasses underwater. The counterlungs are of a coaxial design. That is, the exhale counterlung is situated in the inhale-lung. The result of this design is a lower breathing resistance. The scrubber is made of Plexiglas. When Spherasorb® is used, the designer claims the CO2 saturation is made visible by the indicator in the absorption material.
The rebreather was shown at Boot 2003 and can be bought for between € 1500,- and € 2000,- depending on the chosen accessories. Further information can be found on the website http://www.submatix.com or you could ask Uwe Lessmann.

This is a real improvement. I wrote in 2003 that the Azimuth mouthpiece should be looked at for design reasons. These guys did that! The mouthpiece operated fantastic. It is very smooth, and van be closed and opened without any problem and with ONE hand! 10 points! for this mouthpiece

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!
