The OASys™ indirect/direct evaporative cooler contains an Indirect Cooling Module, which first cools incoming fresh air without adding moisture. The air then passes through the direct cooling module, is cleaned, and humidity is optimized. The cooled air enters the space directly or through conventional duct configurations and exits by roof vents or other openings. The small amount of water used in this process is renewed periodically by a self-purging reservoir. The key to OASys is a unique heat exchanger combined with a single pump/blower configuration. According to the manufacturer, unlike conventional air conditioning systems, which recirculate indoor air, the evaporative cooler continuously conditions and delivers fresh outdoor air. The unit produces up to 3.5 tons of cooling while using less than 600 W for an energy-efficiency equivalent to better than 40 SEER, said the company.
