Heai-Surface (Fan System) The G & O Manufacturing Company 138 Winchester Avenue New Haven, Connecticut INDIVIDUAL FIN TUBING RADIATING ELEMENTS FOR UNIT HEATERS (High and Low Pressure) AND CONCEALED RADIATORS INDUSTRIAL HEATING COILS REFRIGERATING CONDENSERS EVAPORATORS, INTERCOOLERS, AFTERCOOLERS, COOLING COILS AND OTHER HEAT TRANSFER PRODUCTS Individual G & O Fins--The use of individual fins results in high efficiency in heat transfer from primary tube surface to secondary fin surface, because all G & O fins have ample collars around the tube opening insuring liberal contact with tubing. Any Size or Shape--Fins of any size or shape may be obtained giving any desired proportion of primary and secondary radiating surface. Square Fins--A square fin has about 30% greater surface than a round fin of a diameter equal to a side of the square. along tubes. Individual Fins--Individual fins permit of any fin spacing: also, of using fins in groups at intervals Fins placed at practically any angle on tubes. Various Shapes--G & O individual fin tubing is furnished in straight lengths: in U bends with short radii: in continuous return bend coils(`or other shapes. Ends of tubes may be left free of alloy for mechanical joints. G & O Individual Fin Tube Data Standard Sizes Fin Surface O.D.

Pioneer Manufacturers of Individual Fin Tubing in this Country 822 Heaters, Unit Electric Air Heater Company Division of AMERICAN FOUNDRY EQUIPMENT CO. Mishawaka, Indiana, U. S. A. Manufacturers of Industrial and Domestic Electric Air Heaters Experience of hundreds of users arid many operation tests by power and public service interests, insurance companies, United States Government and other authorative Front View institutions have proved that the Electromode Electric Air Heaters are practical for hundreds of varied applications. They incorporate the unit heater principle in which forced air circulation provides uniform temperature. They are clean, convenient, instantaneous, efficient, fully automatic and portable. The low initial ^cost and minimum installation expense ^enables economical heating for many applications. The heart of the Electromode Heater is the I heating unit. This consists of a helicoil, sheathed wire type (Galrod) of resistance heater element cast integral with an Heater Element_____________ aluminum alloy fin type grkK The heat Back View transformed from electric energy is quickly Industrial Eleclromode AU-Electric Unit Heater conducted through the finned area of the heating unit and is carried off by the forced Eledromode "Built-in-Wall'' air circulation. The operating tempera AU-Eleciric Heater ture of the unit is comparatively low and with the special cut-out switch, absolute Eledromode Portable safety is assured. AU-Eledrii Heater In addition to the industrial type, the Electromode Heaters are made in domestic models. The "built-in-wall" type and the portable model are both ideal for home use where occasional heat is required. Write us for complete information on the Electromode Line of heaters Mode!
