NOTES

AutoCAD SHX Text General Electric Dwg T-9742927. There are 14 coils made of 1-inch finned copper tubing. The diameter of the tubing in the finned areas is 1 5/8". The coils are bent circular and there is an outer and inner ring with seven (7) tubes stacked vertically in each ring. There is a 1/4" steel brass stiffener plate located in between the 3rd and 4th tubes vertically from the bottom that provides rigidity to the coils. Vertically, the tubes are arranged on 2 1/4" centers. The diameter of the outer ring is 68" center to center. The diameter of the inner ring is 59" center to center. There are six (6), 1" brackets spaced evenly around the cooling coils that hold the coil tubes in place. The intake and the outlet of the cooling coil is fabricated with 2" copper tubing and both feed a common manifold.
