This model has been designed mainly for use in cold water. The MC7
diaphragm first stage comes with the standard issue antifreeze kit and
the second stage is identical to the one used in the Ellipse Titanium.
The first stage of the Ellipse Alaska is the already famous and
excellent Cressi MC7 model balanced diaphragm. It comes with the
antifreeze kit, which provides an additional waterproof chamber, to
screw onto the end of the first stage. This chamber ends with a silicon
diaphragm on the outside that seals off the inside from contact with
water, while still transmitting any pressure variation to the inner
organs, thanks to the flexibility of the material.
The antifreeze kit
is composed of two main parts, both made from strong chrome-plated
brass. There is a mushroom element inside, made from acetylic resin,
which connects the external diaphragm to the internal one. The use of
the antifreeze kit completely eliminates any water seepage into the
external part of the first stage, so not only does it prevent the
formation of ice in this area, but it also prevents the formation of
deposits and incrustations on the diaphragm and on the spring. This
provides considerable advantages for divers working in mineral-rich
water or with lots of suspension (archaeological sites, port works,
caving etc.)
Features
The first stage of the Ellipse Titanium is the already well-known and excellent Cressi MC7 balanced diaphragm model. It comes with both international yoke or 200 or 300 bar DIN connection; this is a hyper-balanced
model that guarantees improved performance when the tank pressure
diminishes. This highly useful feature means the regulator gives of its
best in the concluding phases of the dive, notoriously the most
important for correct de-saturation of the tissues.
The first stage is a compact size and has a very strong structure. It also has an optional antifreeze kit, which completely seals the spring and diaphragm from contact with the water.
The second stage of the Ellipse Titanium is made from a futuristic cocktail of titanium and new generation high-tech polymers.
The former is well-known for its properties – rust resistant,
mechanically strong and very lightweight. The high-tech polymer used
for the casing is futuristic, boasting flexibility, mechanical
strength, a capacity to absorb shocks and reduce noise that are truly
original in this sector.
