Industrial Cooling Tower

   
Fills
 

The principle of operation of cooling tower fill is to put as much water surface area in contact with as much air as possible, for the longest amount of time possible. Depending on type of cooling tower, application and available circulating water quality the fill will be selected very carefully from below available fills:



(a) PVC Film Fills
 

Film fills allow the water to form thin flowing sheets to expose as much water surface area as possible to the interacting airflow. Fills are double edge folded to provide additional strength, erosion resistance at edges and longer life. These PVC fill shall be resistant to rot, decay, or biological attack and non-brittle. The PVC fills have excellent fire resistant qualities, with a flame spread rating as per ASTM-E84.

Higher temperature fills are available for water temperatures exceeding 55 degree C. Consult your “Nirvana” representative for further details.

We use below type of PVC fills:

(i) Cross-Fluted Film Fills: Cross fluted PVC film fills, which offers maximum heat exchange surface area, minimum pressure drop and higher water-air mixing time in result increase cooling tower thermal efficiency. Suitable for good water and industrial water quality.

(ii) Vertical Offset Fills: This fills has less fouling change, efficient and maximum surface area.

(iii) Vertical Fills: Good for dirty water, low fouling and low pressure drop.





(b) Splash Fills
 

Splash fills are good for dirty water application and offer low pressure drop. Below available splash fills are used for “Nirvana” cooling towers:

(i) Wooden Splash Bar: Chemically treated wooden bars used for cross-flow cooling tower.

(ii) PVC ‘V’-Bar: PVC ‘V’ Bars makes small droplets by splashing and shearing of water drops which produce better heat transfer efficiency. Used both for cross-flow and counter-flow cooling tower & suitable for turbid water application.

(iii) Opti-Grid: Opti-Grid is a direct replacement of splash fill for use in cross-flow and counter-flow towers where dirty water is concern. Opti-grid utilizes a floating hanger design that allows the fill layers to float for excellent fit in slanted cross-flow designs. This design offers reduced pressure drop, improved splash surface, non-fouling ability and maximum strength. Good for sea water and turbid water.

(iv) TURBO Splash PAC: Due to innovative design, there is no risk for the fills getting chocked, less resistance to the passage of air allows energy saving. Suitable both cross-flow and counter-flow cooling tower and any type of water quality including sea water.



PVC Drift Eliminators
 

“Drift” is the undesirable loss of liquid water to the environment via small droplets that become entrained in the leaving air stream. These water droplets carry with them chemicals and minerals thus impacting the surrounding environment.

“Nirvana” uses profile or cellular both type eliminator to ensure maximum removal of water droplets from air stream to limit the drift rate upto 0.005% of circulating water flow rate. With low drift rate, the “Nirvana" cooling tower saves valuable water and water treatment chemicals.

The drift eliminators are constructed of polyvinyl chloride (PVC) plastic material which effectively eliminates corrosion of these vital components. They are assembled in sections to facilitate easy removal for inspection and maintenance of the water distribution system and top of the fill area.
