Brentwood CF150MAx Cellular Drift Eliminator

High surface area and wide cell spacing allow CF150MAx to provide cost-effective and efficient drift removal at minimal pressure drop for counterflow applications.

  • High surface area provides maximum performance at minimum pressure drop.
  • Patented Mechanical Assembly (MA) technology for environmentally friendly, glue-free packs that can be assembled on-site.
  • 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 0.001% circulating water flow (Test Method CTI-HBIK Standard 140; with proper installation and use of Dri-Seals).
  • Material meets CTI Standard 136.

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

CF150MAx Counterflow Cellular Drift Eliminators are a cost-effective, high efficiency drift eliminator specifically designed to maximize drift removal. 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.
