Treadwell has designed and manufactured electrolytic oxygen generation systems for the United States Navy. Treadwell saw service on Nautilus and 598 class submarines with Model 7L16 EOG that produced 90 SCFH of pure oxygen. Over the next nine years company developed more efficient 7L16 EOG versions that by 1965 were producing 125 SCFH of oxygen. In 1965 Treadwell designed and produced the electronically controlled, water cooled 6L16 EOG, producing 150 SCFH of oxygen. In the 90s firm further upgraded the EOG to a completely Automated EOG (AEOG) using a digital microprocessor. In 2007 Treadwell won the Low Pressure Electrolyzer (LPE) solicitation, whose purpose was to replace existing oxygen generators on both Seawolf and Ohio class submarines with new technology. The LPE uses a state-of-the-art proton exchange membrane electrolysis cell stack to produce 225 SCFH of oxygen. Treadwell is staffed and equipped to assemble and test oxygen generators to all pertinent military specifications.
