Stealth CDLSE

Stealth SC is the ideal, cost effective apparatus for a range of specialist diving operations where simplicity, ease of use and durability are a necessity.

Stealth SC (Semi-Closed) is a mechanical underwater Life Support System (LSS) designed for Mine Counter Measure / Explosive Ordnance Disposal (MCM / EOD) operations to 54 metres using nitrox breathing gases or to 60m using a helix or trimix breathing gas.

Stealth SC is a back-worn LSS, with gas provided by a twin, two litre cylinder assembly via an adjustable constant mass flow metering valve. A demand valve automatically provides gas into the counter lungs during decent, which may also be used as a manual gas bypass valve.

Stealth may be supplied with an integrated open circuit emergency breathing Secondary Breathing System (SBS), which may be augmented by a separate eXternal Breathing System (XBS).

Configuration Options:

Stealth SC is a modular, underwater life support system that can be tailored to suit mission requirements by using a combination of the following accessories:

Buoyancy compensation device with integral weight pockets
Bite mouthpiece and half mask
Open circuit bailout options for both bite mouthpiece and dual mode mask
Optional separate low magnetic external breathing system (XBS)
Full face dual mode mask, permitting breathing from closed and open circuit gas supplies such as XBS or special operations manned wet submersible built-in breathing system (BIBS)
Dual mode bite mouthpiece

Non-magnetic and low acoustic design

The requirement to meet NATO AEODP-7 Class A (STANAG 2897) without compromise is an operational necessity. Stealth CDLSE fully meets the requirements of AEODP-7 Class A (STANAG 2897) under both static and dynamic test conditions in all attitudes and for all components that may come into contact with magnetically sensitive ordnance.

Sea mines continue to increase in sophistication; in response Stealth CDLSE surpasses the low acoustic test requirements of NATO STANAG AMP15. Stealth CDLSE functions by analysing the breathing gas and through the automatic addition of 100% Oxygen, the Partial Pressure of Oxygen (PO2) is accurately maintained at a pre-set level dependent upon the depth.

Using three independent oxygen sensors, Stealth SC's control system rapidly and accurately responds to changes in life support system status.

A Diluent gas (Air, Heliox or Trimix) provides gas volume within the closed-circuit primary breathing system, whilst Carbon Dioxide (CO2) from exhaled gas is absorbed by the scrubber unit.
