The article offers information on equipment used to control temperature and humidity at the RainForest exhibit of Cleveland Metroparks Zoo complex in Ohio. The area has two air-handling units (AHU), one used primarily for cooling, while the other is equipped with a pre-heater and humidifier rack. Both AHU have 10-feet diameter, 1,000 pound heat wheels, which transfer moisture from stale exhaust air to dry outside air once every 2.5 hours.
