PVC Round Eliminator

Product Description

CDS130146 made out of rigid PVC is designed to remove maximum entrained drift particles from air stream efficiently with minimum pressure drop thereby reducing the fan power requirement. A time proven design the cellular drift eliminators are an economical lightweight and efficient solution for drift elimination. The eliminators can be assembled as well as cut at the field installation to ensure tight fit.

Cellular type drift eliminators have been tested in laboratory conditions as well as found wide acceptance in the industry and can limit the drift loss of less than 0.0005% of the circulating water. While the eliminators are designed to ensure nesting/interlocking with adjacent modules, in order to achieve these high efficiencies care has to be taken to ensure that no short circuit paths for the water are left during installation.

Principle of Working

The cellular eliminator module structure gives the three-pass structure that creates centrifugal forces on the droplets. The droplets get attached to the drift eliminator surface as a result of inertial forces, resulting in high drift elimination efficiency. The sinusoidal shape of the module ensures minimum resistance to the air travel path thus exerting minimum additional driving force on the fan.

These water droplets are drawn out of the air stream into the drainage channels. The resultant large water droplets fall out of the entering side of the modules without being re-entrained.

Structure and Strength

The CDS130146 drift eliminators provide a rugged cellular structure formed by the solvent bonding of sinusoidal shaped corrugated sheets. Individual S-shaped corrugated sheets are bonded with subsequent layers to create the structure. The entire area is thus divided into several smaller S-shaped mini zones.

The modules are provided additional strength by the insertion of stiffener sheets at regular intervals. For higher duty conditions, the number of stiffeners is recommended to be increased.
