The cooling tower is designed and manufactured to provide long-term heat rejection services in commercial and industrial setups. However, the device is not everlasting or infallible. If it is neglected throughout the year, it will decline in terms of performance. Moreover, the internal components might degrade significantly, and this will lead to accelerated damage or premature failure. Therefore, you should ensure that proper maintenance is performed. One of the critical servicing maintenance aspects which you should consider for your cooling tower is fan shaft bearing lubrication.
