XSTREAM RANGE

The objective; design the most reliable 1st stage in the world. A patented ruby ball seal is automatically positioned by the floating seat which balances any upstream pressure equally with the pressure adjustment spring, maintaining the benefits of having a perfect ball as the sealing element without the risks that follow with incorrect sealing pressures. This makes the Xstream Range self-balancing, giving the same high performance, irrespective of the pressure in the cylinder.

Added to this the range has a built in anti freeze protection in its construction. The TDA (Thermo Dynamic Antifreeze) ensures that the through-flowing water keeps the ice away, entirely without fluids or extra diaphragms.

Description

Poseidon Xstream Deep Regulator is the regulator of choice for any demanding divers that dive with air or trimix with a maximum of 21% oxygen. New Poseidon Xstream Regulators come with an OPV (over pressurization valve) in the 1st stage, and use a standard LP hose with an adapter on the 2nd stage. Excellent choice for rebreathers.

XSTREAM 1ST STAGE

• The first stage is a balanced rolling diaphragm ball valve producing extreme leak tightness. Conventional designs are sensitive to wear, misalignment, and manufacturing precision. A ball always finds its correct place.
• Combined with the 2nd stage, the enormous capacity of the 1st stage make the regulator meet the EN 250 breathing performance requirements even at as low as 16 bar (232psi) cylinder pressure. This means that you gain an extra 34 bar (493 psi) of gas compared to most other regulators!
• The Xstream construction requires less o-rings than any other regulator. Except for sealing the blind screws (3-4), there is just 1 sealing o-ring (semi-static) in the bottom mounted versions and 2 in the side mounted.
• The hose routing is developed to be optimized for a redundant system, using two regulators. The HP ports are positioned to accommodate the use of gas monitoring computers e.g. first stage mounted HP sender/receive units

XSTREAM 2ND STAGE
A number of features greatly improve safety and ease of use:

• If debris has degraded the function of the exhalation check-valve, it can easily be reached and corrected by just twisting off the diffuser. It is the only part which needs to be disassembled, and if it gets lost during the operation, the regulator will continue to function but must only be used for immediate ascent.
• In case of a malfunction in the 1st stage causing excessive intermediate pressure, the safety valve integrated in the1st stage will bleed off the excessive gas. This system both indicates to you that something is wrong so that you can take action, and because of the up-stream servo-valve technique, allows the regulator to continue to breath normally.(conventional downstream regulators are likely to free-flow in such a situation).
• Integrated surgical hose fixing points safely secures the regulator to the diver, but in an emergency allows a distressed buddy to retrieve the regulator without undue stress to the diver.
• The dead air space is low at just 49.5 ml (3 in3) making CO2 figures (hypercapnia) minimal. Inhalation resistance is incredibly low and unaffected by depth and breathing pattern.
• Because of the unique Poseidon valve technology, there is no need for external adjustments.
• Xstream is fitted with the new ergonomic mouthpiece Poseidon AIR, with asymmetrical lugs for the most comfortable bite.
• All diaphragms are protected so that a strong current or using a scooter or tug does not affect either inhalation or exhalation.
• A minimal number of moving parts, coupled with thermodynamic engineering, ensures the safe use in an extremely cold environment.

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.

Poseidon Cyklon X Metal Regulator

Robust, high performing, easy to use and cold water ready - the Cyklon just works. Poseidon's Cyklon regulator has been put to the test for over six decades. Through continuous and gradual improvements, the Cyklon guarantees the highest performance under all circumstances. Now as Cyklon X updated for Nitrox and Oxygen.

KEY PERFORMANCE FEATURES:

• No manual adjustment of breathing resistance needed, performs equally well at all depths
• Side purge prevents current-induced free flow, for example when scootering
• EAN 40 ready and compatible
• Ambidextrous, works perfectly either way up, from left or right side
• No environmental sealing required for cold water

CYKLON - EVEN MORE EXPERIENCED THAN YOU...
A regulator must possess a set of functions which are unaffected by the different environments it will see during its lifetime. Examples of these functions include inhalation resistance, exhalation bubble distraction, noise and leak tightness – to name just a few. Different environments such as cylinder pressure, diving attitude, depth, temperature, gas, type of water, the diver can have an effect on these functions.

When a new regulator is released on the market, it has to pass the EN 250 test. This test represents one single environment; the manufacturer may have managed to test perhaps another hundred such situations, which is good but not necessarily enough. Only after years and years of actual use by divers around the world will the manufacturer collect all the information which can guarantee a perfect performance under all circumstances. This of course, takes time...

The Poseidon Cyklon Junior was introduced in 1958. In small steps, it has been gradually improved every year, based on both divers’ experiences and technological evolution. And so it continues.

The expression “been there – done that” applies to The Poseidon Cyklon more than to any other regulator on the market.

POSEIDON REGULATOR TESTIMONIALS
Poseidon Regulators have repeatedly come out on top in US Navy testing and studies. During the NEDU McMurdo Antarctica testing program, the Poseidon Xstream was the only regulator that suffered no free flows.
Other Navy-approved regulators need extra environmental membranes and fillings with silicone oil in order to operate in cold water. This approach is wrong as it adds failure points that can quickly worsen cold water performance.

Regulators and harnesses at the Lyndon B. Johnson Space Center in Houston, TX, for space pre-mission training at the Neutral Buoyancy Lab (NBL).
Poseidon has established a protocol for O2 cleaning that NASA has adopted for their nitrox regulators.

Poseidon Regulator Xstream Duration 90

You are a technical diver performing your last deco stop just meters beneath the ice in frigid waters, you know that prolonged exposure could be your demise, you also know that surfacing before planned is equally dreadful.  In this moment, a free flow would be catastrophic.

If you were to choose one regulator to trust, wouldn’t it be the only one that suffered no free flows in all of the US Navy Antarctic testing? 

No matter how extreme the environment (pun intended), you want to breathe on something reliable.  That is why divers choose the Xstream Duration.  It has the same main functions of the Xstream Deep but meets all four of the O2 requirements for blends containing up to 99.95% O2.  It is the ideal stage regulator.

Xstream Duration 90 is approved for diving with pure oxygen (99,95%) and that makes the regulator suitable for usage as a deco regulator. But it can also be used for diving with Trimix and Nitrox. Top of the line regulator for tech divers and public safety divers!

The Duration comes standard with no hose, so that divers can choose what hose they prefer. For a Poseidon 02 ready hose we have the following hose options: 27.5", 35.4", 43.3", 59", 84.6" Click Here for Poseidon Hoses

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
