Sistemas de arrefecimento fluido/Ar FLKS-1H


The FLKS-1H is a compact fluid/ air cooling system with a plastic tank housing and integrated air duct. This lightweight and robust design
makes it suitable for diverse applications.


The pump conveys the operating fluid from the tank through the part being cooled to the heat exchanger.  The axial fan provides the necessary air flow through the heat exchanger to cool the operating fluid.
