Closed-Loop Cooling Described

Closed-loop enclosure 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.
