POSEIDON T.D.A
Xstream has a built-in Poseidon T.D.A,
ThermoDynamic Anti-freeze, which requi-
res no maintenance. It is always there,
doing the job. It is thermodynamically pro-
tecting the parts which must not freeze.
It is identified by the large slots in the
cover, allowing the heat energy of the wa-
ter to reach the spring. The cold from the inside is conse-
quently insulated from the spring, via an insulation barrier
and insulating diaphragm. It is constructed without com-
promise to any detail to prevent cold reaching the sensitive
area. Using Poseidon T.D.A, a regulator can free-flow air in
fresh water of 0ºC (32ºF) for at least 10 minutes and after-
wards still be completely unaffected
DEEP / DEEP90 1:ST STAGE (TRIMIX, AIR)
All materials in Xstream Deep are chosen and tested to be
optimised for Helium and high flow. This requires special
attention to leak tightness, since Helium gas has such a
low density.
All o-rings are of the highest Nitrile quality, and rated for
use down to -40ºC (-40ºF)
Deep 1st stage comes in two different versions. One side
mounted and one bottom mounted. Both versions are certi-
fied to 200m (656 ft) depth, and colour-coded black which
in most countries represents a bottom gas mix.
The bottom mounted Deep was discontinued in 2005
Deep must never be used with an oxygen content > 21%,
or a helium content > 77%.
