Aerofin Corporation Air System Equipment f1S`a"*fa Aerofin Corporation Air System Equipment Heat transfer Surface Fig. S 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. O.D. copper or admi ralty. Casings--Copper, aluminum or galvan ized iron. Fig. 6 Booster Aerofin (Fig. 5)--straight tube type, single pass construction for pres sures from 1 to 200 lb gauge. Headers--steel. Tubings--% in. O.D. copper. Casings--copper, aluminum or gal vanized iron. Recommended where small coils are needed or to raise the air temperatures in branch ducts. Fig. 8 Aerofin Heavy-DutyIndustrial Heating Coil (Fig. 4) for use where extra-rugged coil is needed for close control. Steam pressures from 25 to 450 lb gauge; tem peratures to 550 F. Headers--Pressed steel. Tubing--1 in. O.D. heavy copper. Narrow Width Aerofin: (Fig. 6) recom mended for water cooling or for flooded Freon systems. Made in straight tubes only with headers on opposite ends, joint between headers and tubing being brazed. Construction similar to Flea- Casings--12-gauge galvanized iron. tube Aerofin. 1344 Fig. 7 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 100 lb steam, followed by 450 lb air with coil submerged in water. Fig. 9 Aerofin Direct Expansion Units: (Fig. 9) Centrifugal Header Type--For cooling air, using Freon expanded directly into the coil.
