Treadwell Corporation

For over 50 years Treadwell has designed and manufactured electrolytic oxygen generation systems for the United States Navy. Shortly after the Korean War the U.S. Navy searched for a company with the technical capabilities to design and build an Electrolytic Oxygen Generator (EOG) to provide breathing oxygen for the crew of its newly developed class of nuclear submarines. For this critical application, the Navy needed a contractor who not only could handle the technical and manufacturing challenge, but who also had a record of the highest possible reliability. The Navy recruited Treadwell, and we`ve been on board ever since. We first saw service on Nautilus and 598 class submarines with our Model 7L16 EOG that produced 90 SCFH of pure oxygen. Over the next nine years we developed more efficient 7L16 EOG versions that by 1965 were producing 125 SCFH of oxygen. As submarine technology advanced, so did we.
