AIR COOLED AFTER COOLER - Boosting Blasting & Painting Performance

Need of Aftercooler

Dry Compressed air is indispensable for fault-free performance of blasting and paint spraying equipment as well as for any compressed air tools.
In a compressor as the temperature rise due to compression, the moisture in the compressed air is present in the foam of vapor. As the air coming out of the compressor cools down during the flow though hoses, the vapor will condensate to liquid water.

Generally the air from a compressor is very warm and contains water and oil, this can cause the abrasive to jam up the blast pot or can have moisture presence on the blasted surface. A conditioned compressed air contributes to improving the quality of blasted surface since most of the oil and water have been removed from the air coming out of a compressor.


In an air cooled aftercooler, the principle of heat exchanger using air as a cooling media is followed. The cooing block consist of brass tubes with aluminum cooling fins. An axial fan driven by pneumatic motor which blows large qualities of ambient air over the compressor air which is in contact with the cooling block or heat exchanger surface, cools off. The compressed air to cool to approximately 9°C above ambient temperature. Due to this cooling effect moisture present as water vapor condensate to liquid water and separated by the centrifugal oil and water separator fitted at the outlet of the aftercooler. CLEANBLAST™ after coolers removes all contaminants and ensures higher qualities of dry and clean air.
After being conditioned the compressed air is dry enough to provide a continuous flow of abrasive media. Because of this feature the amount of blasting system breakdowns, maintenance and repairs is reduced to a minimum.
Standard after coolers are complete pneumatic operated and fitted with pneumatic motors, moisture separator, oiler, and silencer and mounted on a heavy duty transport frame.

Features

Air cooled compressed after coolers cool the compressed air with atmospheric air as cooling media. The compressed air is cooled to approximately 9°C above ambient temperature. This causes the oil and water vapor to condense so it can be removed by the separator.

CLEANBLAST™ after coolers removes all contaminants and ensures higher qualities of dry and clean air.

Standard after coolers are delivered with pneumatic motors, moisture separator, oiler , silencer and mounted on a heavy duty transport frame.  The option of electric motor is also there.
