XF150MAx Crossflow Cellular Drift Eliminators

XF150MAx
Crossflow Cellular Drift Eliminators

XF150MAx Crossflow Cellular Drift Eliminators are specifically-designed to achieve maximum drift removal efficiency in crossflow tower applications by providing an upward flow path and discharge angle of 40-55° from horizontal (depending on installation angle) and molded-in drainage channels that direct the collected drift back to the wet section of the tower even when impacted by water spray.

The modules are constructed of a series of sinusoidal-shaped corrugated CTI STD-136 PVC sheets that are mechanically assembled to mating sinusoidal structural waves to form closed cells. These cells force the drift droplets carried in the leaving airstream to make three distinct changes in direction. This disruption of the air flow creates centrifugal forces on the drift droplets, forcing them to be captured by inertial impaction and direct interception with the module walls and thereby removed from the airstream.

Applications
The XF150MAx is designed for applications requiring very low drift levels in crossflow Cooling Towers, Evaporative Cooling systems, Scrubbers, and High Humidity Cooling systems.

Features and Benefits
• The upward flow path and discharge angle of 40-55° from horizontal (depending on installation angle) is specifically-designed for crossflow applications. The XF150MAx is fully-effective even when installed vertically.
• Installed at the standard 10° from vertical (as shown at right on Brentwood XF-600 Supports), XF150MAx modules are strong enough to span 10 ft (3.0 m), requiring fewer support beams and less air blockage.
• XF150MAx modules "nest" with the modules next to them (below left) to provide "seamless" drift removal. This nesting design makes the nested space between packs a fully-functiioning drift removal cell instead of a "dead space" that can allow drift droplets to completely bypass the drift eliminators (below right).

• Patented “MA” (Mechanical Assembly) Technology for environmentally-friendly, glue-free packs that can be assembled on-site
• Can be field cut for a tight fit around columns and other structures without sacrificing structural integrity.
• High surface area (cell dimension of 1.50" [38mm]) provides maximum performance at minimum pressure drop.

Drift Loss
.002% recirculation (Test Method CTI-HBIK Standard 140) is possible in new installations that are properly designed and installed and take advantage of the XF150MAx's fully-nesting design and Brentwood DriSeals. Retrofitting older cooling towers with XF150MAx Crossflow Drift Eliminators will also result in significant improvement in drift emissions.

Pressure Drop Curve
Pressure Drop testing is currently being conducted on this newly-introduced product. As soon as the testing is completed and verified, the results will be published here.

Materials
XF150MAx Crossflow Cellular Drift Eliminators are made from PVC material that meets CTI (Cooling Tower Institute) Standard 136 and is UV protected. The PVC compounds used in Brentwood cellular drift eliminators have outstanding resistance to weather exposure, and are nearly impervious to chemical degradation by alkalis and acids, grease, fats, oils, and biological attack. PVC has an excellent fire rating due to its self-extinguishing characteristics.
