Case study - helping submariners breathe

Submariners rely on our combined oxygen generating systems (COGS) and COremoval systems to breathe.

Our smart technology uses electronically charged membranes to separate water into oxygen and hydrogen. We also use a novel way of managing the hydrogen, carbon monoxide and other gases to create the optimum safe environment. Despite having over 11,000 components the system is compact and we’ve reduced its size to meet the design specifications for the Royal Navy’s ‘Astute’ class boats and are refining it further for the UK’s future submarine programme.

The technology is tested for the highest performance and reliability, as the UK’s submariners put their trust in us to breathe hundreds of metres beneath the surface, in one of the world’s most inhospitable environments.
