Sizing
- Determine inlet temperature to aftercooler
- Determine desired outlet temperature. (Aftercooler outlet
temperature = ambient temperature + approach)
- Determine needed approach. (Approach = desired outlet
temperature - ambient temperature)
- Find flow (SCFM) under column of correct inlet and approach
temperature and read left for model number.
Approach Temperatures
To use the approach temperature tables you need to decide if you
want a 5, 10, 15 or 20 degree approach temperature. Second you need
to know your flow rate (SCFM). Third you need to know the
temperature of your compressed air as it leaves the air compressor
(discharge temperature). For example:
- Air Compressor produces 250 SCFM
- Compressed air discharge temperature 250 F
- And we want a 10 F approach temperature
The correct unit for these conditions is a
AC-140
Approach temperature is the difference between the ambient
temperature and the compressed air temperature. So, going back to
our example. If the ambient temperature is 75°F and the
approach temperature is 10°F than the compressed air will be
approximately 85°F at the outlet of the air receiver. The
compressed air enters 250°F and leaves 85°F. It is critical
to have a separator and drain installed at the outlet of the
aftercooler to collect all the moiture that drops out as the air is
cooled.
