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.
