The evaporative cooler module is designed to deliver cool and humidified air in regions with a hot dry climate. Units are designed for indoor or outdoor installation.

Packages are available in sizes that can handle up to 20,000 CFM. Units have a large access door on the side to provide access to all electrical components and to facilitate the removal of filters. Standard features include 12" thick Celdek media. Units consist of a galvanized enclosure with removable 12" media and pre-piped, pre-wired controls. Units are designed to work on standard water line pressure, and have a built in moisture control and temperature switch.

To satisfy a variety of installation and climatic requirements units can be joined together in conjunction with other modules, which include direct fired or indirect fired module and/or blower section. All modules bolt together to form a rigid common base structure that mount onto a single curb structure.
