CS Tubes With Extruded Type Aluminum Fins for Air Coolers

CS tubes with extruded type aluminum fins for Air Coolers

Tube: OD1’’, 14BWG, CS

Fin: OD 2 1/4’’, Pitch 8FPI, thickness at crest 0.3-0.4mm, Aluminum B221-6063

Fin thickness0.4mm (0.016’’) is standard size for many air cooler suppliers——to name a few: Hudson, Harsco/Hammco, Thermal etc.

Some kinds of finned tubes can be effective cleaned with a fairly high-pressure water spray. Extruded fins are generally much tougher than helically wrapped fins. I have even seen people walking on them, but this is not recommended. They are also better for a salty air environment, since they have much more resistant to corrosive attack, which can eventually cause helical fins to break and loose all contact with the tubes.

If your finned tube bundles have L-footed, helically wrapped fins, then cleaning is a bit of problem because the fins are rather fragile.
