This was followed, In 1949, by two 74,800 sq-ft condsnscrsfor Waterside 8tatlonNo. 1. Now, Worthington Is again building (or Con Edison tho "world's largest" singlo-eheti condenser ever ordered, 128,000 sq-ft, single-pass, for tho 160,000-kw Unit No. 7 addition to East River Station. Worthington, with over a century of experience in tho manufacture of steam power equipment, is prepared to build efficient condensers in all sixes.
