January, 1912 "TAE MaRINE REVIEW 37 View of Single Unit I. O. C. Generator for producing Oxygen & Hydrogen Works: Waverly Park, Newark, N. J. OXYGEN & HYDROGEN With the HIGH in EFFICIENCY--LOW in COST - HE I. 0. C. system for producing Oxygen and Hydrogen offers advantages which, for the purity of the gases and the economy of production costs are not equalled by any other system. As backing up this claim, where the cost of electric current is Ic. per kw. hour pure Oxygen and Hydrogen can be produced by the I. O. C. system at a cost of about 1-10 of Ic. per cubic foot. I. O. C. plants are built on a unit basis---they can be installed in any number of units to meet required production and units readily added to meet increased demand; the generators are practically automatic in operation and gases of the highest efficiency are produced. 3 Let us estimate on your Oxygen and Hydrogen requirements. We can save you money and give you gases pf the greatest purity. We install complete plants or furnish gases in cylinders Send for I. O. C.
