Industrial air-conditioner cooling units often are used for cooling sealed enclosures. Yet, a cooler ambient environment could be used to help cool a warm electrical enclosure. Series PKS air-to-air technology takes advantage of a cooler ambient environment in harsh conditions when closed-loop cooling is required. The air-to-air heat exchanger consumes approximately one-third of the power compared to a traditional industrial AC unit, says the manufacturer. Designed for indoor, outdoor, remote and washdown applications that require a closed-loop system to protect electronics, the heat exchangers are offered in five configurations; 22, 45, 64, 100, 150 and 180 W/°C.
