Air cooled aftercoolers
Air cooled compressed air aftercoolers cools the compressed air with atmospheric air.
The compressed air is cooled to approximately 9oC above ambient temperature. A sufficient
capacity aftercooler can take upto 80% of the moisture present in the compressed air.
The BL Series is a complete aftercooler package designed to work on most models of rotary air compressors. To select the appropriate model, simply determine compressor horse power, and select model from the chart.
| ROTARY COMPRESSOR | ||
| Air Compressor Horsepower | Internal Airflow Maximum CFM | Model Number |
| 50-75 HP | 539 | BL 450 |
| 100-125 HP | 785 | BL 600 |
| 150-200 HP | 1569 | BL 1000 |
| 225-350 HP | 2300 | BL 1600 |
Sizing Notes, Recommendations are based on the following :-
Heat Removal : After cooler = Compressor horsepower x 1.15 ( motor service factor ) x .17 (this assumes 17% of input horsepower is rejected to heat).
15oF Approach Temperature : Compressor air outlet temperature - ambient air temperature.
Temperatures : Ambient Air Temperature + 15oF = Compressed Air Outlet Temperature.
Flows : Compressor Horsepower x 4.5 = SCFM Air Flow.
Air flow rates are based on less than a 4 PSI pressure drop @ 100 PSI operating & 100oF ambient and 50% relative humidity.
