Cross Flow Fill Media

Replacement cross flow fill media for commercial cooling towers, available in kits for BAC and Marley towers. Worn, scaled or collapsed fill reduces heat transfer and makes the whole tower work harder, so replacing it is one of the most effective ways to restore cooling performance.

Cross flow vs counter flow cooling tower fill

In a cross flow tower, air moves horizontally across the fill while water falls vertically through it. In a counter flow tower, air moves upward against the falling water. The two fill types are not interchangeable, so check your tower design before ordering. If your tower is counter flow, see our counter flow fill media for BAC, Evapco and Reymsa towers.

When to replace cooling tower fill

  • Scale, mud or biological growth clogging the fill
  • Sagging, warped or collapsed fill sheets
  • Water channelling or uneven distribution across the fill
  • Rising leaving water temperatures with no other explanation

Ordering the right fill

Fill media is sized to your tower, so every kit is quoted to order. Use our How To Measure Fill Media guide on each product page, then request a quote with your tower make, model and measurements. Our parts team will confirm the right fill before you order. Questions? Email parts@commercialhvacparts.com.

Replacing fill is often a good time to check other cross flow components, including air inlet louvers and float valve kits. Browse all cooling tower parts or shop by brand: BAC and Marley.
