Aluminium Heat Exchangerr is a device built for efficient heat transfer from one fluid to another, whether the fluids are separated by a solid wall so that they never mix, or the fluids are directly contacted.  When selecting a Aluminium Heat Exchanger  technology, coolant compatibility with wetted surfaces must be considered. A copper fluid path is compatible with water and most common coolants used within heat exchangers.
Aluminum heat exchangers offer excellent performance with ethylene glycol/water solutions (EGW), oils, and other fluids, but are not compatible with untreated water. The table below shows fluid and heat exchanger compatibility.
