selection procedure
step 1 Determine the Air Compressor’s motor horsepower.
step 2 Enter the chart at the motor horsepower to select the
correct model.
step 3 Check the aftercooler sCFM. The SCFM of air discharged from
the air compressor must be equal to or less than the value in the
chart for the model selected. If it is not, choose a larger model.
If the SCFM is unknown, multiply the air compressor’s motor
horsepower by 4.5 to determine the SCFM capacity required.
Recommended Typical Installation
1. Support piping as needed. Flexible connectors must be properly installed
to validate warranty.
2. Coolers should not operate in ambient temperatures below 35°F (1°C).
Consult factory for recommendations.
3. The fan cannot be cycled.
4. AHP coolers operated outdoors must be protected from weather.
Consult factory for recommendations.
5. If ductwork or additional static resistance is added to the cooler airstream,
an auxiliary air mover may be required.
sizing
1. Oil flow is .45 GPM/HP.
2. Oil pressure drop - 15 psi or less
3. Oil heat transfer based on 100°F E.T.D.
(E.T.D. = Entering Temperature Difference)
(E.T.D. = Oil in Temperature - Ambient Air Temperature)
4. Air aftercooler pressure drop - 3 psi or less.
5. E.T.D. Temperature Correction Factor:
HPchart = HPcompressor x
100

maintenance
Periodic cleaning of the fins with compressed air is needed to remove the
accumulation of dirt and dust. Check the automatic drain on the separator
(not included) periodically.
If the inside of the tubes need to be cleaned of oil and carbon, use a
chlorinated solvent. Do not use strong solvents. Do not use acids or
caustic cleaners.
