CF150MAx Counterflow Cellular Drift Eliminators

CF150MAx
Counterflow Cellular Drift Eliminators

CF150MAx Counterflow Cellular Drift Eliminators are specifically-designed to achieve maximum drift removal efficiency in counterflow tower applications while keeping pressure drop significantly lower than in cellular drift eliminators designed for crossflow cooling towers.

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 CF150MAx is designed for applications requiring very low drift levels in counterflow Cooling Towers, Evaporative Cooling systems, Scrubbers, and High Humidity Cooling systems.

Features and Benefits
• High surface area (cell dimension of 1.50" [38mm]) provides maximum performance at minimum pressure drop.
• CF150MAx 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).
Nested Seams vs. Flat Seams
• Patented “MA” (Mechanical Assembly) Technology for environmentally-friendly glue-free packs that can be assembled on-site
• CF150MAx 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.

Drift Loss
.001% recirculation (Test Method CTI-HBIK Standard 140) is possible in new installations that are properly designed and installed and take advantage of the CF150MAx's fully-nesting design and Brentwood DriSeals. Retrofitting older cooling towers with CF150MAx Counterflow Drift Eliminators will also result in significant improvement in drift emissions.

Materials
CF150MAx Counterflow Cellular Drift Eliminators are made from PVC material that meets CTI (Cooling Tower Institute) Standard 136 and are 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.
