Wayne Products Inc., Malvern, PA, released a comprehensive catalog that describes its complete line of filter and ventilation systems. The Electra-KoolT systems are a "bolt-on" fix for overheated and/or dirty control enclosures in industrial environments. Hot air is blown out of the enclosure using clean, filtered cooler air, which reduces internal temperatures to ambient. The catalog describes seven sizes for use in enclosures having a volume of from 1 to 600 ft^3.
