Air/air heat exchangers use the external temperature for cooling and ensure thecomponents in the enclosure  working in clean, sealant and low temperature enviro-nment and thus make sure its best performance and long life.

The heat exchanger core is made by pure aluminum. By separating the internaland external air circuits, two separate circulations are formed ( interior circulation-interior of enclosure, outer circulation-exteral environment.) The completely separate airflows are routed through the heat exchanger module by powerful fans and thus cooling the enclosure. In general, a temperature difference of 10 K betweenambient temperature and interior temperature of enclosure is ideal.

Outstanding Performance and Design

The requirement for use of air/air heat exchangers is that the amb-sent temperature must be below the required enclosure internal tem-perature. Dust and aggressive ambient air are unable to enter the enc-losure interior, thanks to the two separate air circuits .In all situationswhere the ambient air is sufficient for cooling, air/air heat exchangersoffer effective, energy-saving solutions .The high specific thermaloutput is attributable to the special construction and functional designof the heat exchangers:

1.Compact structure provides big exchanging area

2.Good conductive material

3.Fan can be controlled separately

4.Optimal flow condition.
