Treadwell AEOG(click for details) Submarines travel underwater, but they all need oxygen. Diesel-electric submarines need it for their engines, and must surface to get it, though modern AIP (Air Independent Propulsion) systems allow moderate power cruising for weeks at a time without surfacing. Nuclear-powered submarines can cruise at full power for years, of course, as their engines do not need air. Their crews, however, do. Hence Electrolytic Oxygen Generators (EOGs), which break up water molecules and keep the oxygen for use aboard ship. Treadwell Corp’s Model 6L16 EOG was first introduced in 1965… EOGs & Upgrades SSN-21 OGP(click to view full) The 6L16 breaks up distilled water by passing an electric current through an electrolyte solution (i.e. sea water) in 16 high-pressure cells, connected in series. This equipment can produce 150 standard cubic feet per hour of oxygen, and variants remain the primary oxygen producers aboard the USA’s SSN-688 Los Angeles Class fast attack submarines and SSBN-726 Ohio Class ballistic missile submarines. Treadwell also produces Oxygen Generation Plants (OGPs) for the USA’s high-end SSN 21 Seawolf fast attack submarines, which include OGP electrolysis modules that depend on proton exchange membranes to do the work of separation. The upgrade program is […]
