[av_one_third first] CF1200 Cooling Tower Film Fill [/av_one_third] [av_two_third] CF1200 has been designed for use in factory-assembled counterflow towers in HVAC and light industrial applications. It can also be used as a distribution pad in 3.9” (100 mm) and 5.9” (150 mm) depths where the water contains very low levels of total suspended solids. CF1200 splits the water stream ten times in an 11.8-inch (300 mm) vertical path, balancing high thermal performance and low pressure drop. [/av_two_third]
[av_one_third first] Cooling Counterflow thermacross [/av_one_third] [av_two_third] ThermaCross™ is a drop-in upgrade for standard 19mm-spaced, cross-fluted fills. When engineering the product, Brentwood developed its patent-pending 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 13% better than standard 19mm-spaced products, even matching the performance of 12mm-spaced high efficiency fills at higher fill heights. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] CF1900 is a popular choice for field-erected or factory assembled counterflow towers. It is predominantly used in HVAC and light industrial applications where the water contains low levels of total suspended solids. CF1900 splits the water stream eight times in a 12-inch (305 mm) vertical path, balancing high thermal performance and low pressure drop. [/av_two_third]

This fill is the metallic version of the popular CF1900, offering a high-performance structured packing made from 304L stainless steel. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] Used in the same applications as CF1900, – field-erected or factory assembled counterflow towers – CFS3000 incorporates larger channels for decreased fouling potential in lower quality water. It splits the water stream five times in a 12-inch (305 mm) vertical path, balancing high thermal performance and low pressure drop. [/av_two_third]
[av_one_third first] Cooling Tower Counterflow [/av_one_third] [av_two_third] 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. [/av_two_third]
[av_one_third first] Counterflow cooling tower [/av_one_third] [av_two_third] 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. [/av_two_third]
[av_one_third first] Counterflow ShockWave [/av_one_third] [av_two_third] 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. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] Used in counterflow towers where total suspended solids levels are high, VF19 PLUS features an engineered microstructure for improved water distribution and thermal mixing.

[/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] 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. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] 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. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] Brentwood’s AccuPac® HTP25 (High Thermal Performance) Splash Fill is an injection molded fill that produces heat transfer via droplet generation.

[av_one_third first] [/av_one_third] [av_two_third] For applications where extremely low drift ratings are not required, CF150MAx provides a cost-effective solution with drift loss of 0.001%. Its high surface area and nesting design provide maximum performance at minimum pressure drop. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] D15 drift eliminators are designed for applications requiring low drift levels with minimal airside pressure drop, meaning lower fan horsepower requirements. They offer drift loss of 0.003% and are made from corrugated, UV-protected PVC sheets that are bonded to provide 12-inch- or 24-inch-wide sections in lengths up to 10 feet. Pack stiffness can be varied with the addition of flat, 30-mil stiffener sheets that are bonded to the corrugated sheets. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] D15NEST drift eliminators are designed for applications requiring low drift levels with minimal airside pressure drop, meaning lower fan horsepower requirements. They combine high drift elimination with low pressure drop, yielding an efficient drift eliminator panel with drift loss of 0.003%. Constructed of 15-mil (after forming) PVC corrugated sheets and heavy, 30-mil stiffener sheets, the panels are designed to interlock to form a leak-tight integrated installed assembly. The packs are solvent-bonded to provide stiff, rugged, 24-inch-wide panels in lengths up to 10 feet. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] DE080 Blade Drift Eliminator Modules use a tightly spaced series of sinusoidal-shaped PVC blades that force the leaving air to make three distinct changes of direction, resulting in very efficient drift droplet removal. This performance does not come at the expense of fan energy, as the engineered flow through the DE080 achieves very low pressure drop with drift loss of 0.002%. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] DE097 Blade Drift Eliminator Modules are specifically designed for use in counterflow forced draft cooling towers. Like DE080 and DE120, DE097 utilizes a series of sinusoidal-shaped PVC (or HPVC) blades to achieve excellent drift droplet removal by forcing the leaving air to make three distinct changes of direction, yielding drift loss of 0.004%. Where this product differs is the additional deflector added to the discharge edge of each blade, which increases the velocity of the leaving airstream and directs it away from the intake fans to prevent recirculation of warm, moist air. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] DE120 Blade Drift Eliminator Modules use a series of sinusoidal-shaped PVC (or HPVC) blades to achieve excellent drift droplet removal by forcing the leaving air to make three distinct changes of direction. The 1.2-inch blade spacing allows for good performance at low pressure drop and cost, making the DE120 our most affordable drift eliminator. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] Spectra Drift Eliminators are site-assembled, blade-style drift eliminators that are most frequently used in the replacement market, dirty water applications, and for long spans such as in counterflow, natural draft towers.

It features a tight, nested seal between adjacent modules to prevent air and water bypass, and its refined flute geometry allows less light to penetrate into the tower, thus impeding the growth of algae in the cold water basin. CL80 is available in either individual modules or framed panels at both 3.2” (81.3 mm) and 2.5” (63.2mm) depths [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] CL100 Cellular Inlet Louvers are used in a variety of new and retrofit applications, including air inlets for both package and field-erected counterflow towers. They improve airflow into the cooling tower, keep out debris, eliminate water splash-out – which can cause icing, near-site water damage, and costly water and water treatment chemical loss, – restrict the amount of sunlight into the cooling tower to impede algae growth, reduce noise from the tower, and improve the tower's appearance. [/av_two_third]
[av_one_third first] [/av_one_third] [av_two_third] Cooling tower nozzles direct the hot water in need of cooling to the tower fill. Brentwood’s counterflow spray nozzles are located and sized in order to provide a uniform pattern of water over the fill with no gaps between their spray areas. This enables the fill to be fully wetted out and ensures high performance. [/av_two_third]
