POSEIDON T.D.A
Xstream has a built-in Poseidon T.D.A,
ThermoDynamic Anti-freeze, which requires
no maintenance. It is always there, doing
the job. It is thermodynamically protecting
the parts which must not freeze.
It is identified by the large slots in the
cover, allowing the heat energy of the
water to reach the spring. The cold from
the inside is consequently insulated from
the spring, via an insulation barrier and
insulating diaphragm. It is constructed
without compromise 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 afterwards still
be completely unaffected.
DEEP/DEEP90 1:ST STAGE
(TRIMIX, AIR, NITROX READY)
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 EPDM 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 certified to 200m (656 ft)
depth, and colour-coded black which in
most countries represents a bottom gas
mix.
