After 5-8 years of normal use of general cooling tower, it is necessary to replace the pvc fill. In case of no normal maintenance, the fill needs to be replaced once every two years. If the following abnormalities occur to the fill in the tower, it shall be replaced in time to make the thermal efficiency of the whole tower reach the predetermined goal.

1. Scaling. The packing in the tower has scale, which is generally calcium carbonate scale attached to the fill, which is stone like and hard in texture.
2. Sinking. The fill of the tower body is stained with heavy mud ash, and sometimes a large number of algae grow, which makes the fill sink and cannot be used.
3. Aging. After long-term use, due to the erosion of water and air, the fill is gradually old, brittle and easy to be damaged. The aging of high temperature tower packing is faster than that of ordinary tower, and it is generally replaced once every 4 to 6 years.
4. The fill of cooling tower is seriously damaged due to improper selection or operation. Each type of cooling tower has design work index value, and improper selection will directly lead to serious damage and scrap of cooling tower. However, in the important working indexes such as inlet water temperature and configuration tonnage, if the working index is greater than the design index value due to improper operation, it will also cause serious damage to the filler.
Cooling tower fills also known as the surface or the wet deck is a medium that utilizes parts of the cooling tower in order to build its surface region. An extended surface territory considers the most extreme contact between the water and air which takes more prominent dissipation rates.
A PVC fill will give an extended water-air interface for the warming of air vanishing occurs. The water will be cooled as it slides through the fill with gravity. The cooled water is then gathered in a frosty water bowl under the fill from which it will be pumped again through the same process to assimilate more high temperature.

Our PVC Fills for cooling towers are made of corrugated high-quality PVC films that are edge-folded and vacuum formed for extended service life. Its edge folded technology can help reduce the erosion of the fills and can save the equipment from damages, thus ensuring a longer service life.
Available in black and blue colors, our PVC Fills for cooling towers is FRP induced draft for cross-flow type and counterflow type. Our PVC fills are also made of continuous forming and offer minimum resistance to airflow, thus providing more cooling and lowering power consumptions.
We guarantee that our PVC are durable, providing strength at critical locations and have a uniform thickness. Our PVC fills are very easy to glue at the site and install, therefore saves transportation costs.
