Herringbone Fills
Herringbone fills take advantage of an engineered surface design to distribute water evenly over the entire fill area for high thermal performance. These fills are designed to replace OEM hanging fill sheets in crossflow cooling towers serving HVAC, light industrial, and other process cooling requirements.
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.

Case Studies
NFL Stadium Crossflow Tower Repack
The on-site cooling tower at a popular NFL stadium in the U.S. recently needed to replace their fill and drift eliminators. Brentwood improved the tower’s performance by providing bottom-supported XF75 packs and a combination of integral and stand-alone drift eliminators.
Replacement Of Hanging Sheets With Bottom-Supported Fill
After years of operation, a factory-assembled crossflow cooling tower in Columbus, Ohio, was due for an upgrade. The hanging sheets were experiencing stresses from fouling, so Brentwood suggested bottom-supported fill as a replacement and an upgraded drift solution.
New Fill For Field-erected Tower At University
A tower that was providing comfort cooling to a university in North Carolina utilized OEM hanging sheet material that was failing and falling out of the tower. Brentwood improved the tower’s performance by providing bottom-supported XF75 packs.
Upgrading Plugged Fill & Improving Drift Issues
A two-cell tower in Baltimore, Maryland, was experiencing fouling to the degree that its fill was plugged. Brentwood suggested a high-efficiency, bottom-supported fill with integral drift eliminators as an upgraded replacement.
