For over 40 years Treadwell has designed and manufactured electrolytic oxygen generation systems for the United States Navy. Shortly after the Korean War the United States Navy searched for a private company with the technical capabilities to design and build an Electrolytic Oxygen Generator (EOG) to provide breathing oxygen for the crew of it's 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 126 SCFH of oxygen. As submarine technology advanced, so did we. In 1965 the Navy called upon Treadwell to develop an oxygen generator to meet its increasingly more stringent specifications for extreme reliability and quiet operation. We responded by designing and producing the electronically controlled, water cooled 6L16 EOG, producing 150 SCFH of oxygen. This design has proven so successful that today there are more than 100 6L16 EOGs at work producing breathing oxygen for all of the Navy's SSN 688 and SSBN 726 class submarines.
