Van Air Air-Cooled Aftercoolers

Van Air Air-Cooled Aftercoolers

$0.00
Air-Cooled 20 scfm - 300 scfm

Van Air AC-10 to AC-20 featured

In Van Air AC series air-cooled after-coolers, hot compressed air is introduced to the core as ambient air is drawn across it, leaving the exiting air cooler. AC series after-coolers are normally sized for a 15°F (or less) approach to ambient air. For example, a compressor discharges 250°F air and the after-cooler is located in 80°F ambient conditions. With a 15°F approach, the air exiting the after-cooler will be 95°F and saturated, and the moisture created by cooling from 250°F to 95°F will condense.

Features & Benefits

  • • Horizontal or vertical flow directions
  • • Galvanized steel cabinet
  • • Open vented motor
  • • Pressure drop less than 3 psi at 80-125 psig

How to Size an Aftercooler

Sizing

  1. Determine inlet temperature to aftercooler
  2. Determine needed approach. (Approach = desired outlet temperature - ambient temperature)
  3. Determine desired outlet temperature. (Aftercooler outlet temperature = ambient temperature + approach)
  4. 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 moisture that drops out as the air is cooled.
