Aeronn Corporation Air System Equipment Heat Transfer Surface Aerofin Corporation Air System Equipment Heat Transfer Surface Universal Aerofin (Fig. 3) is distin guished by its "S" bend construction of tubing, units designed with steel headers on opposite ends, the ends of the "S" bends being connected thereto by com pression nuts, the bends taking care of the expansion and contraction of the tubing. Recommended where close control is desired. Headers--Pressed steel. Tubing--1 in. OD copper or admi ralty. Casings--Copper, aluminum or galvan ised iron. Fig. 5 Booster Aerofin (Fig. 5)--straight tube type, single pass construction for pres sures from 1 to 200 lb gage. Headers--steel. Tubings--% in. OD copper. Casings--copper, aluminum or gal vanized iron. Recommended where small coils are needed or to raise the air temperatures in branch ducts. Fig. 4 Fig. e Aerofin Heavy-Duty Industrial Heating Coll (Fig. 4) for use where extra-rugged coil is needed for close control. Steam pressures from 25 to 450 lb gage; tem peratures to 550 F. Headers--Pressed steel. Tubing--1 in. OD heavy copper. Harrow Width Aerofin: (Fig. 6) recom mended for water cooling or for flooded "Freon" systems. Made in straight tubes only with headers on opposite ends, jowl between headers and tubing being brazed. Construction similar to Flexi: Casings--12-gage galvanized iron. tube Aerofin. 172 Aerofin Continuous Tube Water Coils (Fig. 7) are designed for air cooling by circulating cold water through the Aerofin and air over extended fin surface. Made for either horizontal or vertical air flow. Tubes and fins are copper, completely tinned with permanent metallic bond between fin and tubes. Headers are made of steel and casings of heavy gal vanized iron or copper. Tested to 250 lb air with coil sub merged in water. Fig. 9 Aerofin Direct Expansion Units: (Fig. 9) Centrifugal Header Type--For cooling air, using "Freon" expanded directly into the coil. Aerofin Sizes Flexitube: 13 standard lengths, three widths, one and two rows deep. Narrow: same as Flexitube. Universal: 17 standard lengths, two widths, one and two rows deep. - Continuous Tube: 13 standard lengths, three widths, 2-3-4-5 and 6 rows deep. Cleanable Tube: 17 standard lengths, one width, 2 and 4 rows deep. Direct Expansion: Centrifugal Header --H standard lengths, three widths, 2-3-4-5-6 rows deep. Steel Supporting Legs: 18 in. and 24 in. high. Punched same bolt hole centers as Pig.e Aerofin Cleanable Tube Units (Fig. 8) for cooling only made with headers re standard casings. Quickly attached. No other foundation required. Sale: Aerofin is sold only by manu facturers of nationally advertised Fan movable to permit cleaning tubes. Recommended for use where sediment or scale forming chemicals are present in the cooling water. Headers--Fabricated steel. Tubing--Copper or admiralty. Casings--Copper or galvanized iron.
