Air/Water exchangers for cabinets

Air/water exchangers are designed to maintain the temperature of enclosures and more particularly cabinets containing electronic components whose maximum operating temperature is limited (generally to 40°C). The cabinet is cooled by transferring heat to a circulating liquid (treated water or with 5% glycol). Exchangers are a good alternative to air conditioners when a sealing rate higher than IP54 is required in the enclosure and when a cold water circuit is available. They should be installed on the front door, or on the side panels of the enclosure. The exchangers have a temperature setting range of 26 to 40 °C and are supplied with a factory preset to maintain an average cabinet temperature of 35 °C.
