Aftercooler
A fan-cooled aluminium aftercooler that cools the hot compressed air at the compressor outlet and condenses most of its moisture at the very first stage. It reduces the load on dryers and filters and increases the efficiency and service life of the entire air line.
Capacity
120 – 2,100 Nm³/h
Max. Pressure
40 bar
Fan Power
100 – 2,500 W
The First Stage of the Drying System
Compressed air leaving the compressor at around 80–100 °C is cooled to only about 10 °C above ambient temperature as it passes through the ACF series aftercooler. This rapid cooling condenses most of the water vapor at the very first stage, reducing the load on dryers and filters and increasing the efficiency and service life of the entire air line.
- Large heat transfer surface with aluminium heat exchanger
- Outlet temperature only 10 °C above ambient
- Axial fan with guard grille, powder-coated fan housing
- Reduces the heat and moisture load on dryers and filters
- Easy installation at the compressor outlet with threaded connections
- Fixed floor mounting with integrated feet
Operating Principle
Hot air from the compressor passes through an aluminium heat exchanger cooled by ambient air blown by the fan, and is cooled to approximately 10 °C above ambient temperature. Draining the condensate formed during cooling with a water separator installed at the aftercooler outlet is recommended.
Application Areas
ACF series aftercoolers are used wherever compressed air needs to be cooled before drying and filtration.
