XF80MAx Crossflow Cellular Drift Eliminators

XF80MAx
Crossflow Cellular Drift Eliminators

XF80MAx Crossflow Cellular Drift Eliminators provide the best available drift removal efficiency on the market today. The upward flow path, steep water drainage angle, and “tuned venturi section” make this the ideal product for factory-built crossflow towers.

Brentwood ACCU-PAC Cellular Drift Eliminator 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 airstream to make three distinct changes in direction. This diversion of the air flow creates centrifugal forces on the drift droplets, forcing them to be captured by inertial impaction with the cell walls and thereby removing the droplets from the airstream.

Applications
The XF80MAx 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 steep water drainage angle maximizes the drift removal for crossflow applications, making it fully-effective even when installed vertically.
• The engineered venturi design (right) increases the velocity of the exit airflow to “scrub out” smaller droplets.
• The .86” (21.8 mm) flute spacing effectively removes drift (at the lowest pressure drop) in crossflow towers with high air velocities up to 800 fpm (4.0 m/s).
• Raw material meets CTI Standard 136 and has a flame spread rating of 25 or less per ASTM E84.

• XF80MAx modules "nest" with the modules next to them (above 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 (above right).
• Patented “MA” (Mechanical Assembly) Technology for glue-free, environmentally-friendly packs that can be assembled on-site
• Can be field cut for a tight fit around columns and other structures without sacrificing structural integrity.

Materials
XF80MAx 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.
