It may not always be advisable for you to replace the cooling tower fill with fill of the same specification as the previous fill. This is because you may miss an opportunity to switch to cooling tower fill that will perform better. This article discusses some of the factors that you should think about when selecting cooling tower fill replacement.
Cooling tower fill is available in a variety of materials, including rubber and PVC. Select fill material that is durable, formable, flame resistant and stable as water conditions change. It is also prudent to specify fill material that has UV protection in case that fill material will be exposed to the elements during its service life. Compare the data sheets of the different fill materials available in order to select the material that meets the criteria outlined above.
You also need to pay attention to the thickness of the fill material that you select. It is advisable for you to select thicker material if the fill will be exposed to challenging service conditions, such as water that has dissolved minerals in it. You should also remember to specify that the thickness that you select should refer to the material once forming is completed. The starting thickness usually reduces during the forming process.
Cooling tower fill can be installed mechanically. Glue can also be used. However, avoid specifying fill that will be glued into the cooling tower. This is because such fill is harder to install when compared to fill that is attached mechanically. Furthermore, there may be environmental concerns about the glue used to install cooling tower fill. Avoid all those complications by specifying fill that will be installed using mechanical fasteners.
Another key feature that you should consider is the temperature rating of the fill. Select fill whose temperature rating is higher than the maximum water temperature in your cooling tower. In this way, the fill will last for a long time without succumbing to heat stress during peak temperature events.
It is advisable to assess the performance of the old fill before buying replacement fill. That assessment will help you to identify the shortcomings of the previous cooling tower fill. The replacement fill should then be carefully selected so that the shortcomings of the previous fill are addressed when the new fill is installed. Involve an expert in the replacement process if you lack experience in handling such technical issues. Contact a company like Marley Flow Control Pty Ltd.
