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.

|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.
Maximum working pressure : 250psi
Maximum working temperature : 250oF
Cooler : Aluminum
Shroud : Powder Painted Steel.
Fan guard : Zinc Plated Steel.
Fan Blade : Polypropylene Blades Aluminum Hub.
Mounting brackets : Powder Painted Steel.
