Micropore

MICROPORE Submarine and Military Diving

Lithium hydroxide (LiOH) absorbent is used for both active CO2 absorption (powered scrubber systems) and passive CO2 absorption (hanging curtains). Lithium hydroxide outperforms other absorbents at low temperature or elevated pressure such as in disabled submarine, DISSUB. ExtendAir® LiOH curtains provide 55% increase in absorbent weight per given storage volume compared to granular LiOH. What this means to a submarine crew is increased life support duration without sacrificing the limited available space. ExtendAir® curtains outperform granular calcium hydroxide absorbents by as much as 4 times depending on temperature and pressure. The US Navy has approved Micropore’s ExtendAir® curtains for use onboard their submarines (part number RM-0601C, NSN 6810-01-560-3015). The UK Royal Navy approved ExtendAir® curtains for their submarines (OM-0612K, NSN 4240-01-543-3287). Independent testing by multiple Navies (US, UK, Italy, the Netherlands, Singapore, Canada) has confirmed superior performance by Micropore® curtains.
