Cellular Drift Eliminator
What is Drift & How Can We Minimize it?
In evaporative cooling applications, the word drift is used to describe the small water droplets that escape the cooling tower within the air stream. Drift is not to be confused with plume, which is the cloud- or mist-like result of… Read More
Flammability of Fills
Test Methods for the Flammability of Cooling Tower Media
Cooling towers are built from several different materials: wood, metal, and plastics just to name a few. Each of these materials of construction has an inherent risk in its ability to ignite, sustain, and spread a fire event. To properly… Read More
constant at variable airflows
Does a drift eliminator’s drift rating stay constant at variable airflows?
  To answer this question, we must first start with the basics of drift eliminators. Drift eliminators aid in the removal of water droplets from an airstream in a cooling tower. They work by changing the direction of the airflow… Read More
Cooling tower drift eliminators
How Material of Construction Relates to Drift Elimination
The two most common polymers used in cooling tower fills and drift eliminators are polyvinyl chloride (PVC) and polypropylene (PP). Both materials offer the benefits of durability, compatibility with the water environments of most cooling towers and processes, and cost-effective… Read More

Addressing Fire Codes by Using Stainless Steel Products
Due to several fire events that occurred in New York City and the difficulty of extinguishing flames on top of high-rise buildings, building codes have been revised in recent years to include detailed requirements for cooling tower fill combustibility. A… Read More
XF Fills for Fouling-Prone Applications
When evaluating which heat transfer media to install in a crossflow cooling tower, most options can be classified as a film fill or splash media. Film fill, either hanging sheets or bottom supported packs, are typically found in small to… Read More
Crossflow Test Cell
Approach & Range, Explained
A question Brentwood occasionally receives from customers is: “Why is my tower not performing as designed?” Along with the inquiry, we are typically given the hot and cold water operating temperatures for their tower and an observation that the difference… Read More
Brentwood's Metallic Inlet Louvers
All-New Metallic Inlet Louvers
Brentwood is excited to announce our new metallic inlet louvers, designed to complement our existing metallic products. The metallic louvers are intended for use with Brentwood’s metallic fill and metallic drift eliminators. All are ideal for non-combustible, high-temperature applications and are corrosion resistant.… Read More

Specific Surface Area’s Impact on Cooling
In the past when people would try to evaluate and compare different fills to each other, one of the pieces of data they would want to know is the Specific Surface Area (SSA) of a fill. SSA is the amount of… Read More

Process Cooling Loop Filtration: Installation Methods
In a recent blog article, we established the importance of mechanical filtration and reviewed a few common types for cooling tower applications. One of the key considerations for a tower owner when going through the selection process is to determine… Read More
Fouled Cooling Tower Fill
How to Select the Best Filtration System for your Cooling Tower
Why Your Tower May Need Mechanical Filtration Cooling towers are a type of heat exchanger that use direct contact between air and water to dissipate heat from a process to the outside environment. There are hundreds of processes that cooling… Read More
Understanding Cooling Tower Drift Rate
How Surfactants Affect Drift Rate
Drift is composed of entrained particles of water in the exit air stream of the cooling tower. Unlike the evaporated water that is pure, the drift particles will contain whatever soluble constituents are present in the circulating water. This could… Read More
