Closed-loop air conditioners are specifically designed to mount on to
electronic enclosures and remove heat without letting outside air into
the sealed enclosure. This type of cooling is typically used to cool
electronic equipment housed inside a NEMA rated enclosure which
protects sensitive electronics from dust, splashing liquids and
production residues. In the closed-loop system, the heated enclosure
air is drawn into the air conditioner by a powerful blower where heat
and moisture are removed as it passes through an evaporator coil and
forced back into the enclosure, maintaining the NEMA integrity of the
enclosure.
