DE-097 Blade Drift Eliminators

DE-097 Blade Drift Eliminators are specifically-designed for use in forced draft cooling towers. Like the DE-080 and DE-120, these drift eliminators use a series of sinusoidal-shaped PVC (or HPVC) blades to achieve excellent drift droplet removal by forcing the leaving air to make 3 distinct changes of direction. Where this product differs is the additional deflector designed into the discharge edge of each blade that increases the velocity of the leaving airstream and directs it away from the intake fans.

Applications
The DE-097 is designed for applications requiring very low drift levels in forced draft counterflow or crossflow Cooling Towers, Evaporative Cooling systems, Turbine Intake Coolers, Scrubbers, and High Humidity Cooling systems.

Features and Benefits
	• Engineered discharge deflectors (left) on the trailing edge of each blade increase the velocity of the leaving airstream and direct it at a 45° angle away from the intake fans, to prevent recirculation of warm, moist air through the fans. • DE-097 modules "nest" with the modules next to them (below left) to provide "seamless" drift removal. This nesting design eliminates gaps between packs that can allow drift droplets to bypass the drift eliminators (below right).

Materials
DE-097 Blade Drift Eliminators are available in PVC and HPVC (for high temperatures) and are UV stabilized. These compounds have outstanding resistance to weather exposure and are nearly impervious to chemical degradation by alkali, acids, greases, fats, oils, and biological attack. They also have excellent fire rating due to their self-extinguishing characteristics, and meet or exceed Cooling Tower Institute Standard 136.
