There aren’t many parts to a chilled water coil but it still helps knowing the parts before placing an order or calling for a repair. If and when a coil is to leak it usually happens in the copper u-bends. But pressurized water will leak at the weakest point and this can happen in the middle of a coil behind the fin pack. When this happens it is impossible to fix without destroying the fins and therefore losing a lot of efficiency in your coil. Here is a quick rundown of your coils parts.
1. Material: copper, aluminum, galvanized plate.
2. Copper pipe: diameterΦ7, Φ7.94, Φ9.52, inner grooved or smooth tube.
3. Aluminum foil: hydrophilic or bare
4. Fin type: louver fin, flat fin, corrugated fin
5. Pitch of fins: Ø7 1.1~1.8mm Ø7.94 1.4~2.0 mm Ø9.52 1.4~2.3 mm
6. Pitch of holes and pitch of rows: 20.5x12.7mm, 22x19.05mm, 21x12.7mm, 25.4x22mm equilateral triangle arrangement.
