RAE Coil Basics:
Size: Fin Height (FH) x Fin Length (FL)
FH or # of Tubes High: 5/8” (FH/1.5” = # of tubes) 1/2” coil (FH/1.25” = # of tubes)
Face Velocities: Cooling 500 +/-50 Heating 700 +/-100 (Can be Higher based on APD)
Coil Materials of Construction: Typical tube diameters: DX & Water C/H 5/8” & 1/2” Steam 1” & 5/8”
Typical Tube Thicknesses: 5/8” .020/.025/.035/.049 1/2” .017/.025/.032 1” .035/.049
Typical Fin Thicknesses: Aluminum .006/.008/.010 Copper .006/.008/.010
Casing: Cooling Coils = Galv/SS/Aluminum Heating Coils = Galv/SS/Aluminum
Connections: Water/Steam = Steel/Brass/Copper DX = Copper
Dipped Coatings: Phenolic (aka:Heresite) and Epoxy (aka:Electro-fin, Technicoat, E-coat)
AcryCoat: Fin coated with Epoxy coating from the mill (80% less cost than dipped )
Coil Selection: Plan & Spec or Replacement – What is important on each?
What gets the most bang for the buck? #1 Tube Velocity/WPD, #2 FPI then FPM/Rows
