Our proprietary systems have produced breathing oxygen for every Nautilus, 637, 688, 726, Seawolf, and Ohio class submarine in the fleet, and today we continue to pioneer state-of-the-art proton exchange membrane (PEM) electrolyzer technology, custom electro-chemical systems, hydrogen generators, and precision oxygen cleaning services for military and aerospace applications. Experience or strong background in Proton Exchange Membrane (PEM) technologies — electrolyzer / fuel cell systems, oxygen / hydrogen systems, chemical processing, gas separation, gas and liquid delivery, water treatment, or military / submarine equipment.
