Brentwood’s AccuPac® Offset-Fluted Fills combine the low-fouling characteristics of vertical flow with the enhanced water distribution of cross-fluted designs. OF21MA’s design yields comparable thermal performance to CF1900 but with lower potential for fouling at a lower cost. It is generally used in field-erected and factory-assembled installations for applications where water contains a moderate level of total suspended solids.

The OF20SB Offset-Fluted Fill combines the fouling resistance of a vertical flow product with the thermal performance of a cross-fluted design. It is a solvent bonded fill that is made in metric dimensions to function as an easy drop-in replacement for metric dimensioned offset-vertical fill products. The OF20SB is typically used in field-erected or factory-assembled installations for power, refining, chemical, steel, food processing, and HVAC applications.

ShockWave™ is a thermally engineered advancement to standard vertical-fluted products. Its enhanced vertical flute orientation and patent-pending PowerCurve™ design leverage the fouling resistance of vertical-fluted products with the thermal performance of high-efficiency fills.
Brentwood has improved the use of the sheet surface area and incorporated diamond tube channels that provide a clear vertical sight path through the product. These design features promote mixing of the air as it moves through the pack, maximizing evaporative heat transfer and exceeding the performance of cross-fluted fills while incorporating the fouling resistance of vertical-fluted products.

Used in counterflow towers where total suspended solids levels are high, VF19 PLUS features an engineered microstructure for improved water distribution and thermal mixing. This fill has been tested and accepted by a major U.S. utility in an operating natural draft cooling tower. Its typical applications include the power, refining, chemical, mining, and food processing industries.

AFVF19 is ideal for metric counterflow cooling towers used for utility and industrial applications where surface waters are used for make-up. Tested extensively in an operating natural draft cooling tower serving a central station power plant, this unique fill features a vertical flute design with an engineered microstructure to laterally redistribute air and water for highly efficient thermal performance.

VF3800 is designed for use in the same counterflow applications as VF19 PLUS, but features larger flute openings and eliminates the microstructure to allow for maximum water velocity.

Brentwood’s AccuPac VF5000 is the most fouling resistant fill in our lines of anti-fouling modular film fills. Built with rigid triangular, vertically oriented flutes, VF5000 is designed for the most demanding fouling applications. With only 98.4 m2/m3 (30 ft2/ft3) of specific surface area, water film thickness is optimized, providing maximum water film velocity, and therefore, the highest shear stresses to maintain surface cleanliness.
VF5000 is the fill of choice when critical operations – such as steel production, mining, food processing, and power production – cannot withstand cooling disruptions due to downtime caused by fill plugging or cleaning. With a top layer of CF1900 cross-fluted fill acting as a water redistribution layer, thermal performance of the fill section is maximized while cleanliness is maintained.
