The Turbo Air 3000 Centrifugal Compressor Operator’s Manual
· Tubes The tubes must be cleaned using a series of brushes (in the case of the intercoolers and
aftercooler) or a rod (in the case of the oil cooler) and then given a thorough soaking with a
commercial descaling agent such as RydlymeÒ.
· Fins The aluminum fins of the intercoolers and aftercooler must be cleaned using a high pressure
air, steam, or water spray and then given an additional soaking with a commercial cleaning agent
such as Coil BoilÒ.
Instructions for cleaning both the water and air sides of the intercoolers and aftercooler are included
here, along with instructions for cleaning the oil cooler.
Refer to Section Seven, Parts and Service, for complete information about ordering specified commercial
products required for this procedure.
Intercoolers and Aftercooler Cleaning
Water Side:
Use a gun-cleaning or tube-cleaning kit for this procedure. Such commercially available kits come with
a selection of brushes in varying sizes, making them ideally suited for this purpose. The recommended
range of brush sizes is from 1/4” to 3/8” (6 to 10 mm), to allow the user to begin cleaning with a
smaller size brush and then progress to the largest size.
1. Shut down the compressor and exhaust all air pressure. Lockout the main motor starter and close
the system block valve.
2. Shut off the cooling water and remove the supply piping.
3. Drain the coolant, and then remove the intercooler headers.
4. Remove the intercoolers from the cooler cavity. (Refer to Figure 5—3.)
5. Inspect the cooler casings for corrosion. If necessary, clean the casings.
