88-09: The Usage of Fiber Cement as a Film Type Fill Media in Evaporative

This paper provides a chronology of the use of fiber cement as a film-type fill media in evaporative cooling towers. Three decades of worldwide experience with asbestos-cement fill systems are reviewed. Topics of discussion include design variations, durability, and thermal performance aspects of the various fiber-cement fill-system designs. Economic and regulatory forces behind the continued large-scale usage of asbestos-free fiber-cement fill sytems in West Germany's cooling towers are explored.
