Herringbone Film Fill

Select A Product:


AccuPac® Herringbone Film Fills for crossflow cooling tower systems utilize a proven herringbone surface design to distribute water evenly over the entire fill area for high thermal performance. The fill packs have honeycomb bonded edges on the air inlets and outlets, plus interlocking offsets that space the sheets to form strong, stackable packs.

Brentwood has invested heavily in research, development and testing of all cooling tower fill and drift eliminator products over the years. We have collected results from thousands of high-performing installations. Whether your needs are for counterflow or crossflow tower applications, we can provide expert, data-driven recommendations for the correct fill replacement to meet existing design criteria or improve upon older tower installations.
