Brentwood CF80MAx Cellular Drift Eliminator

Offering the best drift removal efficiency of any drift eliminator on the market today, CF80MAx is designed for counterflow towers and features a beveled drainage tip to reduce pressure drop by up to 25 percent in the tightly spaced module.

CF80MAx is designed for applications requiring very low drift levels in counterflow cooling towers, evaporative cooling systems, turbine intake hoods, and scrubbers. With field-verified drift test results of 0.0004% per CTI Standard 140 (the industry standard for testing cooling tower drift), there is no need to use double layers of drift eliminators to achieve high drift removal efficiency.

  • 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 Mechanical Assembly (MA) technology for environmentally friendly, glue-free packs.
  • Strong enough to span 6 feet, requiring a small number of support beams and reducing 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).
  • Nests with adjacent modules to provide seamless drift removal by eliminating gaps between packs that can allow drift droplet bypass.
  • Drift loss of 0.0005% circulating water flow (Test Method CTI-HBIK Standard 140; with proper installation and use of Dri-Seals).
  • Material meets CTI Standard 136.

Materials

All Brentwood Cellular Drift Eliminators are made from PVC material that meets Cooling Technology 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, acids, greases, fats, oils, and biological attacks. PVC has an excellent fire rating due to its self-extinguishing characteristics.

Product description

CF80MAx Counterflow Cellular Drift Eliminators are specifically designed to achieve maximum drift removal. Unlike dual-purpose drift eliminators designed for both counterflow and crossflow applications, Brentwood’s counterflow eliminators have significantly lower pressure drop. The modules are constructed of a series of sinusoidal-shaped, corrugated PVC sheets that are mechanically assembled to mating sinusoidal structural waves, forming closed cells. These cells force the drift droplets being carried in the leaving airstream to make three distinct changes in direction. These forced changes to the air flow create centrifugal forces on the droplets that remove them from the air stream by causing them to impact the module walls, collect, and drain back to the wet section of the cooling tower.
