All standard Energy Flow® coils
feature 5/8" OD or 1" OD seamless copper tubes
conforming to ASTM specifications. Standard 5/8" OD tube
wall thickness is 0.020 inches, except Type WR and WRC coils,
which use 0.025 inch wall. Standard 1" OD tube wall
thickness is 0.035 inches. Heavier wall tubing is available.
Copper-nickel, aluminum, stainless steel and carbon steel are
available material options.
With the exception of type WR
and WRC coils which feature roller-expanded tube joints, all
joints for Energy Flow® heating and cooling water 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 help in
choosing the right material for your needs.
With the exception of type WR and WRC
coils, standard Energy Flow® 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 WR and WRC cooling coils use carbon steel tube
sheets and removable carbon steel headers with threaded
Energy Flow® coil casings are heavy gauge galvanized steel
for high strength, durability and are double flanged for 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 welded casings for airtight applications.
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 WR and WRC coils are tested hydrostatically to
150 psig. Higher design and test pressures are available for
