In 1992, Carmellan research was involved in the development of the SMS 2000 rebreather. Testing was carried out under licence from Dräger. Stuart Clough principal of Carmellan research and Pete Readey were heavily involved in testing. I am trying to find out the full story and history of this rebreather. Unfortunately, there is very little to be found about this unit. I hope for your cooperation to complete this story before this history is lost. Now 30 years after these test dives, there is almost nothing to be found about this system.

Hereby a call to send any available information on this rebreather. Among other things, I am curious if this unit is a derivative of the MCM100. The term SMS indicates Self – Mixing – System. The MCM100 and was a self-mixing units. This is where dräger seems to want to move towards ECCR. It seems Dräger never decided to commercialise any ECCR. Later SMT7000 was build.
The Dräger SMT 7000 is a mechanical self-mixing rebreather, developed for mine clearance dives and a replacement for the FGT 1.
Developed for dives up to 60 metres, it mixes oxygen and diluent gas to maintain the PPO2 value throughout the dive at an optimum level. This value is measured continuously and can be seen on a display. Integrated in the SMT is a separate back-up unit.
The Dräger SMT 7000 is worn on the back, compact and easy to handle.
The Dräger SMT 7000 has been developed according to the following standards: STANAG 2897 level A and AMP – 15 (STANAG 1097).
