CF80MAx Counterflow Cellular Drift Eliminators

CF80MAx
Counterflow Cellular Drift Eliminators

CF80MAx Counterflow Cellular Drift Eliminators are specifically-designed to achieve maximum drift removal. Unlike other drift eliminators designed for both counterflow and crossflow towers, Brentwood's counterflow eliminators have significantly lower pressure drop than dual-purpose eliminators

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 CF80MAx is designed for applications requiring very low drift levels in counterflow Cooling Towers, Evaporative Cooling systems, Turbine Intake Hoods, and Scrubbers, providing the best drift removal efficiency. With field-verified drift test results of .0004% per CTI Standard 140 (the industry standard for testing of cooling tower drift), there is no need to use double layers of drift eliminators to achieve high drift-reduction efficiency.

Features and Benefits
•Beveled Drainage Tip design reduces pressure drop by up to 25% (based on air velocity of 800fpm [4.1m/s] over non-beveled design
• Patented “MA” (Mechanical Assembly) Technology for environmentally-friendly glue-free packs.
• Heavy Duty CF80MAx modules are strong enough to span 6 ft (1.8 m), requiring fewer support beams and less air blockage.
• Can be field cut for a tight fit around columns and other structures without sacrificing structural integrity. Dri-Seals are recommended for maximum performance.
•All Brentwood Cellular Drift Eliminators modules "nest" with the modules next to them (below left) to provide "seamless" panel installations.

Drift Loss
.0005% recirculation (Test Method CTI-HBIK Standard 140) is possible in new installations that are properly designed and installed and take advantage of the CF80MAx's fully-nesting design and Brentwood DriSeals. Retrofitting older cooling towers with CF80MAx Counterflow Drift Eliminators will also result in significant improvement in drift emissions.

Materials
All Brentwood Cellular Drift Eliminators are made from PVC material that meets CTI (Cooling Tower Institute) Standard 136 and are UV protected. These PVC compounds 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.
