Brentwood sheet thicknesses are quoted in final gauge (as measured in field) of .008' (.203 mm), .010' (.254 mm), .015 (.381 mm), or your specific requirement. All Brentwood fill products are available in PVC and are UV stabilized. The PVC compounds used in Brentwood fills have outstanding resistance to weather exposure and are nearly impervious to chemical degradation by alkali, acids, greases, fats, oils, and biological attack. Brentwood PVC has excellent fire rating due to its self-extinguishing characteristics, and meets or exceeds Cooling Tower Institute Standard 136. HPVC (high temperatures), PP (polypropylene), and ABS plastics are also available for special applications.

Since there are many different systems to which cooling towers are applied, there are many different fills used in them, each with their own benefits. The vast array of fills on the market can make your head spin as you review competing offerings. With our experience in and knowledge of cooling towers and fills, we can help make sense of your options to find the best solution to meet your needs.
CF has been designed for use in factory-assembled counterflow towers in HVAC and light industrial applications where the water contains very low levels of total suspended solids. It can also be used as a distribution pad in 2' [51mm], 3.9' [100mm], and 5.9' [150mm] depths. CF splits the water stream ten times in an 11.8' [300mm] vertical path, yielding high thermal performance and improved water distribution.
ThermaCross' is a drop-in upgrade for standard 19mm-spaced, cross-fluted fills. When designing 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 airflow and 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.
Used in the same applications as CF, ' field-erected or factory assembled towers ' CFS incorporates larger channels for decreased fouling potential in lower quality water. It splits the water stream five times in a 12' (305 mm) vertical path, balancing high thermal performance and low pressure drop. With its large sheet pitch CFS is also commonly used trickling filter and biofilter applications.
Offset-Fluted (OF) fills blend the benefits of Cross-Fluted (CF) fills and Vertical-Fluted (VF) fills into products that generally provide relatively high efficiency per volume along with greater resistance to fouling/plugging than cross-fluted fills. These fills were introduced after purely CF fills and purely VF fills showed the effects of opposite ends of the spectrum in fill designs. CF fills revolutionized cooling tower designs because they allowed much smaller fill depths to meet cooling requirements. Unfortunately, their susceptibility to fouling was a rude shock to customers who had historically given little thought to fouling based on towers that were built around the splash fills that preceded film fills. Those costly lessons pushed the market to VF designs to address the fouling problems, but the VF fills gave back a good bit of the performance improvements that the CF fills offered. As the need for greater performance became a market driver, fill designers developed OF fills to bridge the gap between the CF and VF products.
OF21MA's design yields comparable thermal performance to CF but with lower potential for fouling and 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.
Vertical-Fluted (VF) fills provide the greatest fouling resistance of all film fills since they maximize water film velocities and have no crossover points. However this greater resistance to fouling also leads to a reduction in efficiency compared to Cross-Fluted (CF) and Offset-Fluted (OF) fills. The benefit of VF fills is that for dirtier water applications, they can provide a consistent level of performance over time. This is as opposed to CF or OF fills that might perform very well early on but end up plugging and losing most of their efficiency, potentially in even a short period of time, if the water quality is poor enough.
Used in counterflow towers where total suspended solids levels are high, VF19 PLUS features a microstructure that improves water distribution and thermal mixing. This fill was rigorously tested and accepted by a major U.S. utility for use in their fleet of cooling towers. Its typical applications include power, refining, chemical, mining, and food processing industries.
AFVF19 is an evolution of early vertical-fluted fills and is a workhorse in many utility and industrial applications where surface waters are used for make-up. Based on a European design, its available sizes make it an ideal fit for towers based on meter-increment sizes. Like VF19 PLUS, AFVF19 was also rigorously tested and accepted for use by a major U.S. electric generation provider in their fleet of cooling towers.

VF 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 and greater fouling resistance.
VF is the most fouling resistant film fill in our portfolio. Built with rigid triangular, vertically oriented flutes and wide openings, VF is designed for the very demanding fouling applications. The combination of wide openings, no microstructure, and vertical flow maximizes the pull of gravity on the water. This results in high water film velocity and high shear stresses to maintain surface cleanliness. VF has been used in multiple counterflow natural draft cooling towers and power generation, steel production, mining, and food processing applications. VF is also commonly used mixed-media trickling filter and biofilter applications.
'L S Enterprise LLC is an excellent source for Brentwood parts. They have extensive knowledge of cooling towers, and they make sure they are quoting what I actually need and not blindly quote what I ask for. They have caught my measurement errors on more than one occasion saving me from misquoting jobs and being short on parts at a job. Great customer service. '
