Air System Equipment Heat Transfer Surface The G & O Manufacturing Company 138 Winchester Avenue New Haven, Connecticut GdO SQUARE FIN TUBING STRAIGHT LENGTHS--U-BENDS--CONTINUOUS COILS RADIATING ELEMENTS FOR ALL HEAT TRANSFER PURPOSES G&O Finned Radiation Coils for industrial applications are available in a wide range of sizes. Universal U-IOS Standard No. 10 Send for Catalog and Price List THE use of INDIVIDUAL .fins results in high efficiency in heat transfer from primary tube surface to secondary fin surface. Fins of any size or shape may be obtained giving any desired proportion of primary and secondary surface. A square fin has about 30 per cent greater surface than a round .fin of a diameter equal to one side of the square. Individual fins permit of any fin spacing: also, of using fins in groups at intervals along tubes. STANDARD SIZES O.D. of Tube A--Generous Fin Collar provides large contact area between Tube and Fin. B--Tube expanded against Fin Collar; insures mechanically tight joint, made permanent by bond of high tempera ture alloy--complete thermal contact. C--Free air-flow passages; non-clogging. 942 >/.' >/. /.' '/* 3/.' r iy' Fin Size VtT *q- r'd. I'/e'r'd. I'/i* r'd. 1 W rq. P/t' r'd. Fin Sparing & 6 6 6 6 6 6 4 Surface Ltrwar .
