Air-to-air heat exchangers

Air-to-air heat exchangers provide a simple, standalone, low maintenance and energy efficient means of cooling electrical enclosures. The effectiveness of this type of cooling product is fundamentally dependent upon the ambient air temperature and the required internal air temperature; not only must the former be lower than the latter but the available cooling output varies with the difference between them.

Rittal's air-to-air heat exchangers have only two moving parts, an internal fan and an external fan, which draw air through separate circuits of a heat exchanger, ensuring that the ambient air, which may be aggressive, or any debris or contaminants present in it, are not permitted ingress into the enclosure.

Fans fitted in the Rittal air-to-air heat exchanger are maintenancefree.
