ThermaCross^®

ThermaCross is a drop-in upgrade for standard 19mm-spaced, cross-fluted fills. When engineering the product, Brentwood developed its patented MicroBoost™ design to maximize the air-water interface for increased thermal capacity and utilized a more vertical macrostructure for improved fouling resistance.

These design features enable ThermaCross to perform up to 7% better than standard 19mm-spaced products, even matching the performance of 12mm-spaced high efficiency fills at higher fill heights.

ThermaCross Cross-Fluted Film Fill Features

Two horizontally aligned, colored cylinders featuring the CF1200. The top cylinder is labeled "Efficiency" and is fully filled with blue. The bottom cylinder, labeled "Fouling Resistance," is filled with green for half its length, while the rest remains white.

Highly Efficient

Cross-fluted fills offer the highest level of efficiency of all film fill designs, improving heat transfer and maximizing overall tower performance.

Improved Water Distribution

The engineered microstructure incorporated into cross-fluted fills enhances water distribution and thermal mixing.

Dedicated Bond Points

Brentwood’s cross-fluted fills feature bonded edges for added media strength and durability.

Mechanical Assembly

Brentwood’s Mechanical Assembly technology has been improved for the production of ThermaCross, yielding connections that are 50% stronger than glued.
