All standard Aerofin coils feature 5/8" OD or 1" OD
seamless copper tubes conforming to ASTM specifications.
Standard tube wall thickness is 0.020 inches. Heavier wall
tubing is available. Copper-nickel, aluminum, stainless steel
and carbon steel are available material options.
With the exception of type R and RC coils which feature
roller-expanded tube joints, all joints for Aerofin heating
and cooling coils are brazed. All joints for steam heating coils
are silver brazed. Aerofin brazers and welders are ASME
qualified. Optional tube materials may require welded joints;
call Aerofin for guidance.
With the exception of type R and RC coils, standard Aerofin
coils feature carbon steel or non-ferrous headers with threaded
pipe connections (other materials are available). Water coils
are supplied with vents and drains. Type R and RC cooling coils
use carbon steel tube sheets and removable carbon steel headers
with threaded connections.
Aerofin® coil casings are heavy gauge galvanized steel
designed for high strength, durability and are doubled flanged
for coil stacking. Tube supports are provided on various centers
to support the tubes and to provide extra support during
handling and coil stacking. Coil casings are furnished without
mounting holes unless required. Stainless steel, aluminum and
other casing materials are available material options. Special
configurations are available such as welding casings for
With a wide selection of standard circuits, Aerofin can
optimize fluid velocity, maximize heat transfer, and minimize
fluid pressure loss. Special circuits can also be engineered to
meet special performance requirements.
Aerofin's standard coil test is performed with 300 psig air
under water. Type R and RC coils are tested hydrostatically to
150 psig. Higher design and test pressures are available for
